To all 'LU/wm it ,may concern.'

Be it known that JOSEPH H. AMES, residing` at New York, county of New York, State of New vYork, and being a citizen of the United States, have invented certain new and useful improvement-s in an Erection Truck, of whichthe following is a full, clear, and exact description, suchv as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which `illustrate the preferred form ofthe invention, though it is to be understood that the invention is not limited tothe exact detailsof construction shown and described, asit is obvious that various modications thereof within the scope of theclaims will occur to persons skilled in vthe art.

v In said drawings:

Fig.- 1 is a view in elevation, showing the manner of using my improved erection truc-k;

Fig. 2 is a plan view of my device, parts being broken awayto show other parts more clearly;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig. .4 is a central vertical section showing y the driving dog which engages the conveyor chain in operative or engaging position;

F 5 is a fragmentary section showing the dog in theinoperative or release position;

Fig. 6 is a section vtaken on the linev 6-6 of Fig. l; and

Fig. 7 is asection taken on the line 7 7 ofFig. 2 showing the manner of supporting ra seat from the truck bolster.

It is an object of my invention to provide an improved truckuponwhich railway carbodies may be supported during-*erection. .Itlis also Van object ofmy invention to provide a truck of the typedescribed dcsigned to vbe moved forward continuously a chain conveyor or other suitable driv- `ing means during: the construction of the car l body supported thereon. :It is alsoan vobject of my invention to provide a truck of `the type described that 4may .be readily :adapted to support :bodies of .different widths. It is .also -an .object of my invention Vtor provide .a means for quickly engag- -ing ythe truck with or 'disengaging it from the driving means.

With these and other objects xin view, my `improved truck comprises y.a plurality of cast side? frame members 1, of substantially beam shape at the center and having bifurcated ends formed of `channel- -shaoed end sections 2 and seats 3 formed integral withfthe center portion of the side frame to accommodate a reduced endportion 4; formed on a cast bolster member The bolster is of substantially,-beam shape and is secured to theside 'frames by the rivets 6. In bearings '7 formed in the end sections 2 there are mounted axles ,8 which are secured in place by cotter pins 9 and have wheels 10 .journaled thereon. The outer ends of the en'd sections 2 at each end of each side member `1 are vjoined by channel-shaped lend members 1l secured to flanges 12 formed on the en'd sections/2. To the bottom flanges of the end members 11 at the vfrontof the truck there `are secured brushes 13 which serve @to remove small y obstructions from the `rails -14 on which the wheels 10 travel.l -lVheel covers 15 are secured to the end sections 2 andthe upper flanges of the end members 11'and prevent small objects from falling intovthe wheel openings.

rlhe bolster 5 is provided at its center, adjacent to its upper flange, witha bearing 16 to receive a pin 17 which secures cast center lpedestal 18 to its seat on thenpper flange of the bolster 5. The vupper `end of the pedestal 18 is formed with a flat face having a central .circular opening adapted to j receive the cylindrical shank 19 formed on the center plate 20. The center plate 2O is shaped to conform to the worvkiit is int-ended to support and is detachably and rotatably held in the opening inthe ped estal r1S by pin 21 which engages in kcooperatinggrooves `formed inthe shank 19 and in Vthe wall of the opening in the pedestal.

Adjacent each end of the bolsterl 5 zu side pedestal 22 is secured to its seat on the upper :flange of the bolster by a pin 23 which has a bearing, not showinin the bolster similar to the bearing 16. Each pedestal 22 is provided at its top with an opening to receive the shank 24-of a side the walls ofthe opening'in the pedestal.

The side bearings Q5 are mounted eccentrically upon their shanks 2i as illustrated in 'full lines in 3, and adapted to be turned laterally to the position indicated in dotted lines in Fig. 3, it' it is desired to extend the supporting areay ot' the bearings to provide a wider support 'for the work carried by them. Bearings of different heights are provided and are substituted when necessari.v to properly supporty the work.

On the forward side et the web otl the bolster 5 there is mounted a bracket 2T tor supporting a collapsible driving mechanisn'i. The bracket is provided Tith a pair ot projecting arms in which is mounted a pin 28 having a driving dog or puller pivotally mounted thereon. The dog Q9 is long enough to project into slot formed in the floor and engage with the links of a chain conveyor 30 that is driven by any suitable means and at a. suitable speed. The dog 23 has -formed integral therewith a hook 3l adapted to be engaged by a latch secured to bolster 5 by eye-bolts 33, when the dog 29 is raised to the release position as shown in Fig. 5. Mounted in the dog 2t) is a pin 3st upon which an operating, handle 35 is pivotally mounted7 the handle 35 being kept from engagement with the tloor by a support 3G Secured to theV lower flange ot the bolster :'i. There is also pivotallyv mounted on the pin 3i. a yoke 3.7 having a ilat strap-like portion 3S adapted to project through an opening 3f) in the web ot the bolster 5 and to rest upon the bottom flange ot the bolster when the dog 29 is in position to engage the chain 30. The strap-like portion 38 is provided with a tapered projection 40 adapted to engage with the bottom tlange of the bol ster 5, the outer edge ot the bolster' llange having a portion provided with an inclined surface to engage with the inclined sin-face of the projection 40. Yoke 3T is held in operative engagement with the lower llange ot the bolster by a locking cam all moving between the arms d3 ot bracket secured to the web ot bolster The locking cam is lixed to a transverse shaft 4Q having a bearing in the arms d3 olf bracket lf3 and also journaled in bearings on the side trame members l. The sha't't is fitted at its ends with operating handles -i which are limited in their movement by means ot' the stop lugs 46 on the side trames.

For some ot the operations in the construction ot car bodies it is desirable to have the workman travel with the truck so there is provided a seat support ti' upon which a. seat 48 is adjustably mounted. llhe support ll' is provided with oppositely disposed projections lf) and all tormed ot' pairs ot metal strips secured together and to the support TJT and having' their outer ends bent in opposite directions to torni teet adapted to engage with the web and bottom tlange,

respectively. ot the bolster As .shown in i and '7, the end ot the support t7 passed through an opening in the bolster web so that the projection El engages with one side ot the bolster web and the projection en'V 'es with the bottom i'lange on the other side oit the web.

In the construction of' car bodiesl using my erection truck pair ol the trucks are placed on the erection track. spaced the proper distance tor the reception ot the trame members and the i une members. rested thereon. The leading' truck has, itsA dog 3) placed in position to engage the coin.'e},'or chain 20 while on the other truck the dog QS) is held clear ot the chain fill by the latch 3Q, the second truck being pulled b v the trame me1nbers carried thereon. "lo place. the dog Q in the engaging position. the latch 3Q is dis engaged trom the doe' :25) so that the dog Q9 wll take the posib on shown in Fie. l

vith the yoke 2 i? projecting through t-he opening 3f) and t ie projection l0 in engagement with the bolster bottom flange. The locking cani is then brought into engageient with the yoke 23T b v the operation ot the shaft l2 by the han-lle l5 so that thel yoke 3T and projection lll are locked in engeinent with said bok-iter llauge. lt

be noted that the pull evertedibv the dog Q9 on the yoke, 23T tends to operate the locking cam l to 'torce the voke 3T against, the bolster flange. To diseugage the dog QQ Yfrom the chain ltl. the cam 1li is dis- 'eel from the yoke 3T and the dogy 2f) y means ot handle 5K5 until the latch ges with the hook 8l. as shown in .lt will be noted Ytrom the Vforegoing that when two trucks built as described are positioned in spaced relation upon a straight track they provide complemental elements ot' a mobile crectioi'i bench having a variable supporting area tor the aceomimnlation ot work ot dill'erent length and width. lt will also he noted that low side trames ol the individual trucks and the relatively high work-supportiup` pcdestals and the. use ot .s pro\.'ide ample room 'or the operations ot the workmen at the truck positions.

lVhat I claim is:

l. ln a truck` spaced side trames, a bolster connecting said side trames, a driving dog tor the truck carried by said bolster. a latch carried by said dog for engaging the bolster' and holding the dog in an operative position, and means carried bv the bolster tor securing the dog in operative engagement with the bolster.
