I carrying Patented 11 1930- PATENT orrlca m8 4. FISHER, OI KANSAS CITY, IISSOUBI ronrmn rowan arrnuxcn' Application filed Kay 28,

'My invention relates to portable powerappliances and one object is-to provide an appliance of this character. including a vehicle which will enable the appliance to be readily transported from place to place, a

mast mounted upon said vehicle, a motor adjustably mounted upon said mast, and hoisting mechanism for raising and lowering said motor. i While the appliance may be employed to advantage in a variety of places I have designed it more especially for'use in railway yards where it can be employed in repairing box and other cars having sheet metal end 16 and side walls which become bulged by loads shifting while in transit. The appliance may also be used for trimming lumber and other loads that become displaced on flat cars whilein transit and thus save the time and labor of performing this work by hand.

In order that the invention may be fully understood reference will now be had to the accompanying drawings,in which:

Fig. -1 is a side elevation of the appliance coupled to a box car and with one of the front and rear wheels of the .vehicle removed. Fig. 2 is an irregular horizontal section on line 22 of Fig. 1, uncoupled from the box car. i a Fig. 3 is a section on line 3 -3 of Fig. 1. Fig. 4 is a section on line 44 of Fig. 1.

.Fig. 5 is a fragmentary detail showing-the hook-shaped endsof a pair of stays engagin under the balls of a pair of rails.

out the invention I employ a suitable vehicle for enabling the appliance to be readily moved from place to .place by hand; In the present instance I haveshown said vehicle in the form of a truck consisting of a reach 4, front and rear axles 6 and '8, and front and rear wheels 10 -and 12, mounted upon said axles 6 and 8, respectively. The front axle 6extendsbeneath the forward portion of the reach 4' to which it is pivotally connected by arking-bolt 14 so that said axle 6'may swingto the right or left to guide the appliance while the latter is being moved fromplace to place. The front 50 axle 6 is provided with a handle 16 swiveled groove for a purpose which will herein 1928. Serial No. 280,929.

at its rear ends to metallic straps 18 secured to opposite ends of said axle 6.

20 designates a mast which is rigidly secured to the rear end of the reach 4 and the rear axle 8, the ends of which latter are re 55' inforced with a brace 22 secured intermediate its ends to the mast 20. The mast 20 is further secured to the reach 4 by

braces

24 and 26, the latter of which extends from the intermediate portion of the mast 20 to the forward portion of said reach 4. The brace 24 extends from the lower forward portion of the brace 26 to the upper portion of the mast 20. The intermediate portions of the mast 20 and the brace 24 are reinforced and united by a strut 28.

29 designates a suitable motor which is fixedly mounted upon a bracket 32 adjustably connected to the mast 20 by slides 33. The motor 29, in the present instance; con sists of a cylinder 30 and a reciprocatory piston head 34 which latter is equipped with a piston rod 36 projecting through the forward cylinder head-4.4 and provided at its outer end with a fitting 38 havinga V-shaped after appear. The piston head 34is normally held at the end of its backward stroke by a coil spring interposed between said lpiston head 34 and the, forward cylinder ead 44. v Fluid under pressure is admitted to the cylinder 30 through a nipple 46 projecting from the rear cylinder head 48 and equipped with a hose 50 provided with a valve 52 hav-- I ing a relief port 53. 4 Suitable hoisting mechanism is provided for raising and lowering the cylinder 30. In the present instance said mechanism consists of a' sling 54, a sheave 56, a cable 58, and a Windlass 60. The sling 54- extends beneath the bracket 32 and is connected at its upper ends to one end of the cable 58, which runs over the sheave 56 and down to a drum 62.

The Windlass 60 consists of the drum 62, a

'ratchet wheel66 fixedly mounted upon said drum 62, a hand wheel 68 fixedly mounted upon the drum 62, and a' pawl 72 pivotally mounted u on a bracket 7 0 which is firmly securedto ebra'ce-24.- Thedrum 62 is jour- -Q naled in bearings 64 secured to the bracket 7 0. just beneath the coupler D. The cylinder 30 74 designates a coupling member which is folded intermediate its ends and extends backwardly at opposite sides of the mast 20 to which it is clamped by suitable means such as

bolts

76 and 78. The-rear portion ofthe coupling member 74 has a series of holes 80 for the reception of the bolt 76 and to enable said coupling member 74 to be adjusted forwardly when necessary for enga ement with the coupling of a railway car to be repaired.

'A brace 82 is connected at its upper end by a bolt 85 to the forward portion of the coupling member 74 to assist the

bolts

76 and 78 in suppbrting said coupling member. The

lower portion of the brace 82 is secured to a clevis 84 which is fixed to the lower portion of the mast 20. The brace 82 hasia series of holes 86 any one of which is adapted to receive the

bolts

78 or 85 and allow for longitudinal or vertical adjustment of the coupling member 74 upon the mast 20.

88 designates a pair of links secured to opposite sides of the mast 20 and connected to the upper ends of stays 90 formed into hooks 92 at their lower ends for engagement with the under portion of theballs A of railway rails B. The stays 90 are equipped with turn-buckles 94 whereby they may be lengthened or shortened as required.

96 designates a braceconnected at its rear end to a clevis 98 projecting from the intermediate portion of the rear axle .8. l The brace-96 is equipped with a turn-buckle 100 whereby it may be lengthened or shortened as required.

102 designates a lifting jack threaded in the forward portion of the truck 2. The lowof the coupling member 74 which is then connected to the coupler D by means of the coupler pin E, after which the front wheels 10 of the truck are raised with the jack 102 to prevent them from sinking into the ground between the rails B, a large block 108 being placed beneath the base 104 of the jack to pro 'de a wide footing therefor. The applia ce is then firmly secured against lateral displacement by means of the stays 90, the hook-shaped ends 92 of which are engaged under the balls A of the rails B against which they are firmly drawn by proper adjustment of the turn-buckles 94. The free end ofthe brace 96 is then placed against any convenient portion of the box car, in the present instance it being shown bearing against the box car ing from a supply of fluid under pressure,

usually compressed air in a tank having pipe lines leading to different parts of the railway yard for furnishing a supply of compressed air for testing air brakes and other purposes.

Just before admitting air to the cylinder 30 for the purpose of advancing the pistonhead 34, a pipe or round bar G is placed in the V-shaped groove 40 to provide a wide bearing against the bulged portion of the end wall C, so that when the piston head 34 ad-- vancespressure will be applied to said bar G which in turn forces the'end wall G back to its original position. i As pressure is applied against the end wall C, said pressure has a tendency to push the upper portion of the mast 20 backwardly and its lower portion forwardly towards the box car, the coupling 74 acting as a fulcrum, but'such tendency is effectually overcome by the stays and the brace 96 which cooperate with the coupling members74 in firmly holding the appliance in working position. v I

Afterthe end wall C has been pushedback to normal position the valve 52 is adjusted to cut off the supply of fluid under pressure and open the port 53 so that the fluid in the cylinder 30 may escape therefrom and permit the spring 45 to push the piston head 34 backwardly towards the cylinder head 48.

From the foregoing description it is apparent that I have provided a power appliance possessing the advantages hereinbe ore pointed out, and while I have shown and described one embodiment of the invention I reserve all rights to such changes and modifications as properly fall within the spirit and scope of the invention as claimed.
