Specification forming part of Letters Patent No. 115,321, dated May 30, 1871.

` l "To all whom it may concern; Y M `Be `it known that I, JEROME B. HULBERT, of Hermon, in the county ofSt.'l Lawrence and z] State of New York, have invented a new and r `ll useful Improvement `in l Self -Loading and E ."Dumping Cart; and I do hereby declare that `the following is afull, clear, and exact descrips tion thereof, which `will enable others uskilled in the art to make and use the same, reference 1 being had to the accompanying drawing forming part of this specication.-

\ `The ob'ect of this invention is to provide convenien `means `for removing earth and gravelin the .construction of embankments,

" and in excavating, andfor` all purposes for whichthe machine maybe adapted and it.

.s l `fconsists ina box "cr scraper and frame-work .1 and attachment thereto, supported on wheels,

" thescraper being made to load and dump itself as thejwheels move forward, the arrangel ment and operation beingas hereinafter more fully described and specified.

. Intheaccompanyingdrawing, Figure 1 repl` resents a side view with one wheel olif', showing the box or scraper as being loaded. Fig. 2 is ,l a vertical `section of Fig. 4, taken on the line @showing the scraper lled and as being l. transported. or moved. l Fig. 3 is a side view, showing the scrapergreversed and the earth w dumped. Fig. 4 is a vertical section taken on .thelineyyofFig 1.`

B is a t are the axles `lorarms ofthe wheels sups The lower portions ofthe uprights E E (which uprights are rigidly attached to` the shafts) trunnions, `firmlyattached to the sides of the :l scraper,from whichthe scraper is suspended l and on whichI it turns.` G G are links which 3? slots receive theupper endsof the links.

HHare `slotted cam-levers, the form together by the bar I, by means of which the levers and cams are operated simultaneously by tliedriver, whostands on the front part of the platform. J is a spring-catch on the cross-piece K, (which connects the rear ends of the shafts together,) which catch supports the rear of the scraper or balances it on the trunnions. scraper, which engages with the catch. M is a lever (one or more) inserted into a socket or sockets, N, on the rear end of the scraper, by means of which the scraper may be guided or kept steady by an attendant in loading and carrying. These levers are readily slipped out when the scraper is to be reversed or dumped. l

When the scraper is to be loaded the barI s is raised, as seen in Fig. 1, which actionl carries the trunnions down the cam-slots in the levers H H and lowers the edge of the scraper.` Aforward movement loads the scraper. When so loaded the bar Iis brought down, as seen in Fig. 2. The rear of the scraper now rests upon the catch J, and may be supported and kept steady by means of the lever or levers M. Inrthis condition the scraper with its load may be transported any required distance.

When it is desired to dump the load the bar I is again raised, which lowers the edge or blade of the scraper so that it will catch in the ground; but as the forward motion of the cart is, continued the effect is to reverse the scraper or turn it over and dump the load, as seen in Fig. 3.

The earth leaves the scraper as the latter is moving forward, it is consequently leveled ofi' as it is deposited.

l In this example of my invention, it will be seen that the apparatus is adapted to horsepower; but I do not confine myself to any particular kindv of motive power. It maybe operated by a locomotive or traction `steamengine adapted to common roads, the latter of which I design to use.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1.
