SPECIFICATION forming part of Letters Patent No. 463,251,

dated November 1'7, 1891.

Application tiled February l, 1890. Serial No. 338,923. (No model.)

Be it known that I, EDWARD L. LAv'roN, a citizenof the United States, residing at Trenton, Mercer cou nty, New Jersey, have invented certain new and useful Improvements in Coal- VVa-gons, of which the following is a specification.

My in vent-ion relates to dum ping-wagons, and more especially to that class of dumpingwagons which are usually employed inl the delivery of coal and ot'ier similar heavy and bulky objects.

Prior to my invention it has been common to' provide dumping wagons with means whereby the rear of the Wagon could be depressed or the front elevated, so that the contents of the Wagon could be dumped to the rear. It has also been proposed to construct such wagons' so that-'the load could be dumped at the side.` y

One of the objects of my invention is to 'construct a Wagon in such amanner that the load may be dumped either at the rear or at the side at4 pleasure and as is most convenient in delivering the material.

A further object of -iny invention is to provide means whereby the body of the wagon may be elevated to any desired height and inclined at4 any desired angle, either toward the rear or either side of the running-gear.

A still further object of my invention is to provide meanswhereby these various .objects may be attained, which shall be simple, cheap, and not liable to get out of and etl'ective, order, and capable of withstanding the heavy Wear and tear incident to the use of such. Wagons in 'carrying and delivering heavy loads. y

To these ends my invention consists in a du mpin g-wa gon havin gthe capabilitiesherein set forth and provided with means for carrying .them out, arranged and constructed substantially as hereinafter described.

In the accompanying drawings I have illustrated the preferred embodiment of my invention, in which- Figure l is a rear View showing the Wagonbody elevated to deliver the load at one side of the running-gear. Fig. 2 is a side view, partially in section,`showing' the wagon-body in" position for delivering the load to the rear of the running-gear; and Fig. 3 is a plan view to the axle at the rear, and at the front end 'connected to a head-block 4, carrying a fifthwhecl 5, mounted on a head-block 6, supported by 'a platform 7, which in turn is supported.

by a truck-spring S, secured to the axle i). While I have found this to be a most satisfactory running-gear for the purposes of my invention, it will be understood that this forms no part of my invention, and anyother well-known and' suitable running-gear may be used.

The bed-plate l isa substantial structure of frame-work made in any desired manner to properly support the wagon-,body 10 and the operating mechanisms. As shown in the accompanying drawings, it consists of the side pieces l1, connected together bysnitable crosspieces 12 l2, and having on each side of its center a number of cross-pieces 13, although it is evident that this particular construction can beivaried to suit the exigencies of the case. Mounted upon the top of this bed-piece are two segmental track-pieces le, and upon these track-pieces bear the rollers 15, secured to the under side of the wagon-body 10, they being preferably mounted in stands or bearings, as shown. Normally the ends' of the' wagon-body rest upon these segmental tracks through the medium of these rollers; but the main portion of the weight of the body and its lead is supported upon the turn-table 16, mounted in the central, portion of the bedplate. This turn-table 16 consists of asuitable frame-work, preferably circular in outline, to the under 4side of which is secured a track i7, made of a metal plate, circular in form. This turn-table is connected by a pivot 18 to ene et the cross-pieces 13 of the bed-plate to maintain it in itscentralposition,andit is supported upon a series of rollers 19, mountedin stands secured to the cross-piece. There may be any desired number of these rollers, and I have shown in the present instance six, so distributed around the periphery of the turn-table that it willbe supported equally in all directions. This construction l deem of considerable. importance, in that thebearing-surface loo of the track connected to the turntable is ou the under side, and this bears upon the top of the rollers 19. In this wayl avoid the objection tothe use of turn-tables as heretofore constructed, as there is no liability of the track becoming foul and` dirty through the dust and refuse or other mattei;'lod'gingy upon the track and interfering with its free rotation; but Iliave found ltha thetrack in this forni is kept free and clear rom obstructions and allows the turn -table to rotate freely. f

The wagon-body is connected to the turntable through the medium of the links or pitmen 2 0, which are pivot-ally secured at one end to the under side of the wagon-body by any suitable strips or connections and at the other end to a rod or bearing 21, mounted in the frame-work of the turn-table. construction it 'will be seen that the wagonbody, being supported .substantially uponv the turn-table and its ends resting upon the seg.- mental tracks at the end of. the frame-Work, is, free to be turned to either side. of the wagon,v so that its rear can be brought at pleasure to the most convenient place for depositing the load.

In order to prevent the wagon-body turning too far, it being preferable to have it vat ri ght angles to the bed-plate when a side dump is to be effected, I provide a st p 2,2, which in thel present instance I have s ofwn mounted on the central cross-bar 13, which' is adapted to engage arstop 23, shown in dotted lines on the underside of the turn-table. iVhile it will be understood thatl this stop is not absolutely essential, still I/liave found it con- 24 arranged on cach side of the wagon-body and adapted to be thrown down to engage with the sides of the bed-plate when it is desired to secure the parallelism between the wagon-bod y and the bed-plate, or to be thrown up into the position shown in Fig. 2. This arm or lever may be a simple st0p,or, as preferred, may he adapted t0 perform other functions.

In order to elevate the wagon-body and its load preparatory to delivering the latter, I provide on each side of the bed-plate a lifting device, which is preferably in the frm of a toggle-lever, consisting of the arms 25, pivotedtogether at one end and connected at their outer ends to the screwblocks 26. These screw-blocks are mounted upon a shaft 27, supported in the bcdsplato and provided From this.

'at its ends with right and left hand screws enf 4- gag-ng the screw-blocks: .'These screwfblcks are preferably formed with a flat base bear- 'f ing upon the track- pieces 2,8,.n1ounted in the bed-plate, so that the shaft-2,7'is relieved from the direct pressure of the weight of the load, and as these blocks are moved toward 'or from each other by turning the shaft they nieve along this track and are practically supported thereby. These togglelevers,there being one on each side, are not connected directly with the wagon-body, but are preferably tted to bear in sockets 29, which are preferably of metal and secured to the under side bf the wagon-sills.v Y ,t i i;

Some suitable means of turnirigfthe shafts 27 must be provided, and. I have shown each shaft having a squaredv end or4 key-post 30, by means of which, with the aid ofa suitable wrench or key, the shafts. may be turned in.- dependently. W'hen, however, it isy desired to dump the load at the rear, it Iis preferable to operate both of the said shafts 27 sim-uhtaneously, and I` therefore provide means for doing the same, and in the present instance I have shown a cross-shaft 3l, mounted inthe frame-work between the transversefsills and provided at itsV ends with a bevelgear 33, se,- cured to the shafts. In order that theshafts may be rotated independently, notwithstanding this beveled gear connection, I arrange one of the bevel-gears, as 32, loosely upon the shaft 3l and provide a suitable shifting device Si, by means of which it may be thrown.l into and out of gear with the bevel-wheel 33, so that the shafts maybe operated independently or together, as desired, by simply ship ping or uushipping the bevel-gear 32% In order that the `rear end of the wagonbody may be raised somewhat from thebedplate when the body and its load are raised for a rear dump, I provide the toes 35, which are mounted in the bearings 3ti, secured upon one of the cross-pieces I3, and these toes normally rest upon the segmental track li at the rear of the wagon.

To the under side of the wagon-bod y I at'- tach lips 37 ,which are adjacent to th'e tips of the toe-pieces 35 and engage with the same as the body is elevmed, and'thei'eby insure the. elevation of the rear of the body when the screwshafts and toggle-levers are being operated to prepare for a rear dump. l

' Such being the general construction of my improved dump-wagon, I will now describe the mode of operation. iVheri it is desired to dump the load at the rear, the bevel-gear 32L being shipped into engagement 'withits corresponding bevel-gear 33", power is applied to one of the shafts by a suitable wrench or key and the shaft rotated, and this through the intervention of the bevehgears and their shafts causes the other shaft to rotate in unison therewith and the blocks 26 on each side of the wagon-bod y are gradually brought toward each other, causing the togglelcvers 25 to bear against the under portion of the body roo i i m5 IIO' rzo

' elevate the rea-r and to raise the same. As the body commences to rise, the links or pitmen 2O hold the wagon-bod y steady and cause it to move forward slightly, and at the same time the toes 35, engaging the lips 37, act as levers to portion of the body from the bed-plate. lVhen the body is raised to the desired elevation, it is held in position without the intervention of any locking devices and the load is delivered through the me dium of any suitable chute or otherwise, and then the body is returned to its normal position by the reverse movement et' the shafts 27 and is ready for another load. `When, however, it is desired to deliver the load at the side, the stops or arms 2t are turned up, in the manner indicated in Fig. 2, and the body rotated upon the turn-table 16 t0 the position desired, the stops 22 limiting its movement in either direction. Suppose the wagon-bod y to be thrown into the position shown in Fig. l. To elevate the trontendotthe body it is only necessary to operate the shaft 27 on the right-hand side of the bed-plate, and to do this the bevel-gear 32a is unshipped and the key or wrench is applied to the propershaft,

` and the toggle-levers 25, which now bear upon the under side of the wagon-body,

and preferably in a socket-piece 38, operate to elevate the body to the desired angle, and the load may be delivered. Il", however, it is desired v to deliver the load at a higher elevation-es,

links under the rear end.

for instance, over a fence or other obstruction-the whole wagon-body may be elevated in the manner shown in Fig. l. To do this i preferably operate the shaft 27 adjacent to the rear vot the wagon-body to elevate it to the desired position, when the arms or stop-pieces 2l, which are provided with teeth on either side, as shown, may be made to engage with lugs or projections 89 on the bedplate, and thereby serve to support the rear portion olV the wagon free from the toggle The shaft of the toggle-link under the front end of the wagon is then operated and the toggles elevated to the desired angle, and the wasgom'body is then practically supported by the arms 2t at the rear and the togglmarms 25 at the front and is maintained or stcadied by the pitmen or links 2O and, kept from sliding oft trom the bed-plate. 'lhe load then beiner delivered, the parts are returned to theirnormal positions by the reverse movement of the shafts and thennlocking ot the arms 2t and the rotation oi the body and the ti1rn-table lli, when the arms Q4 are dropped into their normal position and the Wagon is in condition to receive another load. it will thus be seen that by the construction set forth l am enabled todeliverthe load at the rearor at either side of thc bed-platc, and i make irse ot the .saine elevating apparatus under either nondition. It will l'nrther be seen that under all 'conditions the wagon-holly is maintained in proper relations to the tiirirtalllo by the links O and may lwvsnplwrlod in :in elevated position at its rear, either by the toc-pieces or, the arms at the side, as the ease may be. lt will further be observed that it requires the least. expenditure of power to operate the wagon-body, the toggledevers and their connecting-screws exerting an immense pressureupon the bottom of the body with the least expenditure of torce on the part of the operator, and as the body normally rests upon rollers it can easily be rotated to either side.

`lv'hile I have th ns described the preferred embodiment of my invention and the means of .operating it, it willloe understood that the details of construction and arrangement may be varied by those skilled in the art without materially departing from the principles of `my invention, and l therefore do not wish to be con fined to the exact construction shown and described.
