WI TNESSES TORN E YS Patented Feb. 23, 1932 UNITED STATES WILLIAM ELMER, OF PHILADELPHIA, PENNSYLVANIA WORK CAR FOR RAILWAYS Application filed July 24, 1930. Serial No. 470,383.

My invention relates particularly to work cars for use on railway tracks, the object of the invention, generally stated, being to provide a car, preferably one that is self-pro- '5` pelled, with means thereon for operating power-driven tools such as spike drivers, spike pullers, nutters and the like, the car having mounted thereon a supporting fra-me accomlnodating one or more beams which are l@ adapted to project outwardly from the frame and to hold the tools in a suspended position in which they can be conveniently applied to track work.

I-Ieretofore it has been proposed to mount power tools on work cars by means of brackets or other forms of extensions which do not permit the tools to be moved towards or away from the work car for convenient positioning at the point where the tools are to be applied.

My invention not only facilitates the movenient of the tools to the desired position, but also provides for the simultaneous operation of a number of tools in advance of and in the rear of the work car, thus enabling the ac- D complishment of more work while the car is standing in one place and reducing the time required to complete a particular operation on a section of track. In the practice y of my invention, tools such as spike drivers or 39 spike pullers are preferably spaced at intervals along the support from which they are suspended, these intervals corresponding to the distance between ties or a multiple thereof, and the front and rear supports are disposed with relation to each other, so that when one tool has been brought to the desired location, the other tools suspended from the same support and from the corresponding 40 rear support will all automatically assume their proper positions.

Furthermore, the work car and its appliances are so designed that at the end of the days work the spike pullers, or such other tools as have been used, may be removed from their supporting beams and loaded on the car platform, and the beams pushed back from their extended positions into housings at the sides of the car whereby the work car '50 and its appliances will take up no more room on the track thanthe space occupied by the underframe of the car.

Other advantages and objects of the invention will be more fully apparent from the detailed description hereinafter of one form or embodiment which the invention may take, the description having reference to the accompanying drawings, whereof:

Fig. I represents a plan view of a work car embodying the invention.

Fig. II represents a side View of the same, showing the application of spike-pulling tools to a track rail; and,

Fig. III represents an enlarged end view of the same, taken as indicated by the lines III- III of Fig. II.

In the drawings there is shown a light weight car comprising generally a car body l, wheels 2 and a supporting frame 3,

to be later described. Mounted at one end kof the platform 4, on the car body l, there is a conventional type of gasoline motor, comprehensively designated by the numeral 5, this motor serving to drive a similarly designated air compressor 6, and, 'I5 if desirable, to drive the work car itself. The details of the power mechanism employed form no part, however, of the present invention for the illustration of which I have selected a common form of power unit.

From an air reservoir 7 associated with the compressor 6, leXible hose connections 8, preferably maintained in a position clear of the ground, lead to the power-driven tools being used for track work. In the drawings, spike pulling machines9 are shown in outline in readiness for operation, but it will be apparent that the apparatus is adapted for use with a large variety of tools including spike driving machines, drills, riveters, nut- 99 ting machines, borers and the like.

The framework 3 on the car body 1 which is substantially co-eXtensive in length with the platform 4 preferably comprises a sub- 95 stantially T-shaped structure having upright members l() and transverse members 11 bridging the uprights and overhanging the rails l2 at the sides of the car. Suitable

diagonal bracing members

13, 14. prevent the 100 ythewo'rkist'obeperformed. ingthe site ofthe work,'the car is stopped frame from racking and give added rigidity to the structure.

Running longitudinally of the car at the sides thereof are box-shaped girders 15 supported by the overhanging members 11. As shown in Fig. III, the girders 15 are provided `with channels 16 at the sides thereof and channels 17 inthe center forming track ways for the tool-carrying beams 18, which are slidably mounted in the girders 15 by means of wheeled carriers 19,' the wheels 20 bearing on the flanges of the

channels

16 and 17. Two tool-carrying beams 18 are employed at each side of the work carythese Abeams being normally housed within the girders 15, but adapted to be manually projected from the frame 3, one beam in arforward and one beam in a rearward direction. To prevent the beams 18 from being pulled outward beyond a certain point, chains 21 are shown attached to the frame 3 at 22 and to the ends of the beams 18 at 23, but other suitable means such as stops may obviously be used for this purpose.

It willbe noted that there'is .a-pair of beams-18 at each side of the work car, and that each set of beams includes one member disposed directly above the inside edge of the flange of a rail 12 andianother member directly disposed aboveV the outside edge of the rail flange. Accordingly, when two beams aremoved endwise from their housings, one forward andone rearward from the work car, the spike pulling tools are moved longitudinally ofthe rail directly above the lineJOfSpikeS, andthe tools can, therefore, lbe .quickly positioned for opera-tion, they forward tools beingapplied to spikes at one side of; therail Vand the. rearward tools being-applied to spikes at the other'side of the rail.

Each tool 9 is suspended by a iiexible connection24 includingal spring .'25, the weight nof the tool being carried on the beamvand the Vtool vhaving suficient` flexibility for adjustment and'proper manipulation by the -operfator. The points of attachment 26 for the tools on the beams 18 are; provided at spaced intervals with a distance between them correspondingv to a multiple of the distanoebe- .tween ties, rand,theprearbeams are'so dis- 'posed'with relation tothe forward beams that when the beams are fully extended the distance between any tool at the rear and any tool at the front of thev work car will equal .amultiple of the distance between ties. In

the example illustrated the tools vare spaced at a distance of four feet from each other, the ties being spaced two feet apart.

When the work car is to be placed inoperation itis driven to the locality at which Upon approachand *the beams'18 are manually runout hefyond the limits of the framework 3 to the position shown in Fig. II, one forwardly Vand one rearwardly from the supporting frame 3. Ordinarily only one pair of beams is selected depending upon which rail is to be worked on. The tools to be used are then taken from the car platform 4 and suspended o from the beams 18 at the points of attachment 26 with their respective hose': connections 8 coupled totheair reservoir 7 vand maintained clear .of the ground. The operator of the work car then proceeds to move the ca r with v the tools suspended as "described, until he sees that ,onetool is substantially in registry with the center of a tie. At this point the car is stopped, Vand itwill be found that each tool is positioned above a tie, the distance between the points ofzattachment :26 onthe-'forward beam an-d. the points yoff-attachment 26 on the rearbeambeing equal to a multiple ofthe distance'between'ties fThe tools-.are

now in readinessfor operation. fDue to the 'g5 which thework is to be performed. vWhile so the weight of tools is carried on the beams' 18, the springsQpermit the operators to fhandily force the tools downward to engagement with rail spikes. lAfter the desired-'work has been performed upon.onesetA of ties, `the -work '-95 car is propelled.v -to anotherzset fof ties,.andV it will Abe observed that the frontV and rear-,tools are so spaced with respect to eachother that repetition can be avoided. Inother words the car may be movedso that in each new .po- T.100

sitiona diiferentset of ties-willbe in registr with the toolstand no tie of asectionof track will be skipped. A vvFrom the :abovedescriptionit willi .heapparent that with the oar at rest, twogangs of "T operators can be set to work, Vone inzadvance .of the work car and one in thefrear,and.t.he operations -on fourties 'canbe completed'. be-

fore it is necessaryto, progressv the .caralong .thel track. By `an obvious modification=:six'?110 tools may .bei usedand six workerseinployed simultaneously on six ties. .When the work `on-a sectionfof track hasbeen. completed; fthe 4tools Aare yremovedfrom vtheir .supporting beams 18, and the beams are returnedto their ifi-15 housings Yin the ,girders 15.

While I -have described myV inventionwith l reference to one embodiment thereof in which specific instrumentalities have `been, selected for performing the various. functionsfof the "(20 work car; it will be appa-rent, especiallyto those skilled in the art, that various changes define'din the appended claims.
