 WE MANUFACTURE 
 
 JACKS 
 
 FOR ALL KINDS OF LIFTING. 
 
 Our Prices are Right. 
 
 ^\^E make the most complete line, and our Jacks are bet- 
 ter adapted to all branches of railway service, from track 
 to shops, and for carrying on locomotives and tool cars, 
 than any manufactured in the United States. 
 
 Jacks for special work, made to order at short notice, and at 
 reasonable prices. All the Jacks we illustrate are made in 
 our own shops and are fully guaranteed. 
 
 Have you ever figured the cost of maintenance and repairs 
 on Hydraulic Jacks and loss of their use while in the hospi- 
 tal ? If not, the figures will astonish you. 
 
 This trouble and expense can be avoided by using the 
 Norton Ball-bearing Ratchet Screw Jacks. 
 
 V/e make one claim only — The Norton Jacks are the 
 best in the world.

 The Norton Ball=bearing Ratchet 
 Screw Jacks. 
 
 TpHE Norton Ball-bearing Ratchet Screw Jacks are constructed 
 on an entirely different principle from any other Jacks in the 
 world ; as will be seen by the cuts, they have a stationary standard 
 and sliding sleeve fitting over the same. The standard has a re- 
 movable nut (usually Phosphor Bronze) fitted within it and rest- 
 ing on a shoulder, in which the screw turns (the standards are 
 hollow, and can be ////<?^/ with oil, thus keeping the screw constantly 
 lubricated). To the upper end of the screw is fastened a steel 
 gear ; a hardened tool steel plate encircles the hub, and rests on 
 the body of said gear, on which are placed circular trains of 
 hardened steel balls, held in place by rings between the rows (as 
 shown in cut). \\\ the top, or head of the sliding sleeve (which is 
 bored to fit standard), is placed another hardened tool steel plate 
 with a hole in the centre, through which the end of the screw 
 projects. 
 
 When the Jack is assembled the sleeve slides down over the 
 screw and standard, the bearing ])late in the head resting on the 
 balls on the plate on the gear, so that the whole weight is carried 
 by the balls (between the steel plates), which act as a thrust-bear- 
 ing between the screw and head of the sleeve, reducing the friction 
 and increasing the lifting power of the Jack. 
 
 The sleeve which revolves on the standard, allowing the lever to 
 be used from either side, carries the load, and is raised or lowered 
 by the screw, which is turned by means of a gear on the rachet 
 shaft, engaging with the gear on the screw, and operated by a re- 
 versible ratchet and lever having the /// and do7vn, or ''pump 
 handle"" motion. This is the only screw Jack made having this 
 motion of the lever. The sleeve at the lower end is provided 
 with a '' stop dog'' or pawl, which prevents the screw from being 
 run out of the nut. 
 
 The advantage of this sliding sleeve cannot be over estimated. 
 It takes all the side strain off the screw, preventing it from bending, 
 and also protecting all the working parts from sand, coal-dirt and 
 water, making it the only Jae-k suitable to carry on locomotives. 
 
 All of the Norton Railroad Jacks are steel and malleable iron 
 throughout.

 WHY WE CLAIM THE NORTON JACKS 
 
 ARE SUPERIOR TO ALL OTHERS, 
 
 Especially for Railway Service. 
 
 Because of their Simplicity, Durability and Cheapness 
 
 They are the Lightest Ratchet Jacks in the world ot same 
 capacity. 
 
 Cost Less for maintenance, are always Safe and Reliable, 
 
 even in the hands of careless and unskilled workmen, as the screvv 
 holds the load without blocking, and cannot drop or run down. 
 This is a very important feature in a Railway Jack and should 
 not be overlooked. 
 
 The screws are Self-lubricating. Ball-bearings never wear, 
 and seldom need oiling or attention. 
 
 They can be operated by ordinary workmen without previous 
 instructions. 
 
 'I'hey can be left standing in Tool Car or Shop, or carried on 
 Locomotive for Months at a time without any attention 
 whatever, and be found Ready for Service when needed, as 
 there is no Alcohol, Packing or Valves to keep in order. 
 
 All Parts are Interchangeable, and can be replaced ina few 
 minutes by ordinary workmen at trifling cost without returning to 
 Factory. 
 
 The Norton Journal Jacks Weigh about one-third and 
 Cost about one-fourth as much as Hydraulics of same 
 capacity, for same purpose. 
 
 All of our Screw Jacks can be used in any position, flat for 
 pushing or bottom up, if necessary. 
 
 The cost for maintenance and repairs on all Jacks in use for 
 past four years averages less than 1 per cent, per annum. 
 
 We will guarantee to keep our Jacks in perfect working order 
 for five years for one-half what it costs for Alcohol alone, for 
 Hydraulics of same capacity and service.

 These Jacks are designed for Extra Heavy Bridge and 
 other work, and are made with great care from the best 
 material, and have given excellent satisfaction. 
 
 When raising light load (30 to 50 tons) use ratchet on 
 upper shaft, which gives more speed. 
 
 When full power of Jack is required, use ratchet on 
 lower shaft.

 without BalhBearings. 
 
 Our Non-lJalMJearing Jacks are made on the same princii)le 
 as the Bali-Bearings, except the load is raised by the end of the 
 screw, which rests on a hardened steel step, or bushing, in the 
 head of the sliding sleeve. Up to 15 tons they are as good as the 
 Bali-Bearing, except they need a little more' attention in oiling. 
 All are fully guaranteed. 
 
 DIRECTIONS FOR NORTON JACK WITHOUT 
 BALL=BEARINQ. 
 
 Keep working parts xue/l oiled. Take particular pains with tlie top hole, as 
 all of the loeight is l)i)rne on the ,?;;f/ of the screw. In oiling the top hole, first 
 till the hole with oil. Then raisi the shell a little to allow the oil to settle well 
 on end of Screw. Do not neglect this, and use plenty of oil. Also see that the 
 screw is kept well oiled. Keep gears 7vell in mesh. ' To adjtist gears— \.oo%en 
 four nuts on cap-holts and check nut on set screw at bottom of cap. Turn set 
 screw till gears are as close in meshes as they will run freely. Then tighten 
 check nut on set screw to hold gears in place, and tighten the nuts on cap-bolts. 
 To take Jack apart, take the nuts off liolding cap, remove the ratchet and gear, 
 then lift the shell up, pressing bottom dog to let it pass groove in top of standard.

 This Jack is intended for carrying on locomotives, for putting in brasses, 
 and yard work. 
 
 It can be placed almost instantly and works very rapidly. The screw being 
 protected, it never gets rusty and useless from exposure on the engine, as is so 
 often the case with common Bottle Jacks, but is always ready for USe. 
 
 Brasses can be changed in half the time, and much easier, than with the 
 old style Jack. 
 
 It would be economy to supply every car inspector with one.

 This Jack is made of malleable iron and steel throughout, with 
 phosphor bronze nut, same as all our bail-bearing Railway Jacks. 
 
 Instead of ball bearings, the end of screw is conical shape, 
 working on a removable, hardened steel plate, fitted in the head 
 of sliding sleeve. In case of wear, this plate can be replaced at 
 slight expense. 
 
 Where a very serviceable and low-priced Jack, from lo^o ij 
 tons capacity, is required, this pattern cannot be excelled; fully 
 guaranteed.

 These Jacks are made on the same principle as the Railway 
 Jacks, and are unsurpassed for all kinds of work. 
 
 They are especially adapted in price and quality to the wants 
 of house movers and others using a large number of Jacks for 
 ordinary work, and in all respects suitable for general service. 
 
 For raising buildings where the sills are close to the ground, 
 the hook will save all the t/iX^i.'-ifijr, conse([uently the Jacks can 
 be placed and the building raised with much less labor and ex- 
 pense than with the common Jacks.

 THE NORTON "SURE DROP" 
 TRACK JACK. 
 
 DESCRIPTION. 
 
 The body of the Jack is of malleable iron, made in two pieces, 
 the sides and bearings of each part being accurately milled, joined 
 together and firmly riveted above the foot, which is in one piece, mak- 
 ing a strong, solid base. The lifting bar is made from best 
 quality forged steel, milled to fit body of Jack, with teeth 
 cut on two sides, one for lifting and one for holding pawl. 
 The teeth in lifting side of bar are cut square on top, making it 
 impossible for pawl to become disengaged while lifting. 
 
 The mechanism for lifting consists of a cam on end of lever 
 socket 3 (see cut 3), working in strap which carries lifting pawl (!. 
 Strap and cam are bored and turned to fit, and hardened. 
 The cam turns on a f inch hardened tool steel pin, which is 
 keyed to frame so it cannot turn. The cam has sufificient 
 throw to raise the bar \ inch, 1 inch, or U inches, as may be de- 
 sired, with one stroke of the lever. 
 
 The teeth on holding side of bar are cut in line with an 
 arc of a circle struck from centre of pin in holding pawl 4 (see 
 cut). Hinged to holding pawl 4, is tripping cam T). 
 
 To raise, turn tripping cam to left (see fig. 1). 
 To trip the jack it is only necessary to turn tripping cam 
 into position as shown in cut 2, raise the lever and turn 
 lifting pawl back. Pressing down on the lever brings the 
 end of lever socket in contact with tripping cam 5, forming 
 a wedge, which in combination with the shape of the teeth on 
 lifting bar, before mentioned, is so powerful that a man can 
 easily and instantly trip with one hand, any load that can 
 be raised with the Jack, even with two or three men on 
 the lever.

 CLAinS. 
 
 We claim that the " Norton " is the most perfectly made 
 track Jack in the market. Our lifting device is the easiest, 
 quickest working and most powerful ever applied to 
 any track Jack. Our tripping device is perfect. It is 
 
 not necessary to lift the load before it can be dropped, as 
 with other Jacks. There are less parts to wear and keep 
 in repair, and each part can be duplicated. 
 
 The wear, if any, being on the cam (which is protected from 
 the sand and grit by the strap) is distributed over so much surface, 
 that it cannot interfere with the working of the Jack, 
 while the perfect fitting of the parts is a great improvement 
 over other Jacks which are nearly all made from castings put to- 
 gether in the rough, with the lifting pawls hinged on small pins. 
 
 In a word, we claim the "Norton" Jacr.s are the nearest 
 perfection of any tools of the kind ever produced.

 These Jacks are designed for use in car repair shops, street 
 railway service, mills, stone yards and quarries, and for truckmen 
 and machinery movers. They are built for speed, and with the 
 crank, light loads can be raised or lowered very rapidly, while 
 heavy weights are easily raised with the ratchet and lever. 
 
 In addition to the crank, we send free with each Jack, a 
 tool steel pinch bar, which will be found very convenient. 
 
 Both the Car and Stone Jacks are made compound or double 
 geared. Fig. 1 represents the compound geared car Jack, 
 broad base. Fig. 2 represents the double geared stone Jack. 
 All have forged steel lifting bar, cut teeth and steel gears.
