FREDERICK E. ALLEN, SAN LENDRQ, CALFORNL.

To rtZZ- whom :It marleen/cern:

Be it known that I, FREDERroK E. ALLEN, of San Leandro, in the county of' Alameda and State of California, have invented certain 'new and useful Im rovements in EX- cavating and Elevating pparatus, of which the following is a speciiication.

This invention relates to portable devices adapted to be movedand located at any spot wherein excavation is to be made, and its object is to provide an improved device of this sort by which the earth to be excavated may be dug by a scraper capable of moving in every direction, and in which the material accumulated by the scraper may be hoisted to a sut'ricient elevation for dumping into a cart. l

Another object of the invention is to furn nish a drive for' the moving parts ofthe apparatus whereby the ldevice maybe operated by horses or ,by a hoisting engine.

The preferred embodiment of the invention is illustrated in the accompanying draw?.

ings, in Wliich,- l

Figure l represents a plan view of the ap- Fig. 2 represents a side elevation of the upper part, and a longitudinal section of the lower part, of the apparatus. Fig. 3 represents a perspective view of the universally movable scraper. Fig. a represents an elevation, showing the scraper tilted up to dump its contents. Fig. represents a perspective view of the conveyer or carriageby which the material is elevated. Fig. 6 represents a similar view, showing the drawers forming the bottom of the receptacle in their open position. Fig. .7 represents a perspecn tive view of one of the drawers. Fig. S represents a perspective view of a clutch forn'xing part ol the elevator-drive mechanism. Fig. S) represents a cross-section'of the carrier, showing;r its manner of support on its guideway. I

'lhe same reference characters indicate the same parts in all the figures.

The apparatus comprises als its base a frame or body portion having two longitudinal side members l which occupy an inclined position when the device is in use, as shown in Fig'. 2. These longitudinal side members or bars are tied together by transverse braces 2. The main frame or body is supported upon the column or standard 3, and stayed by braces 4 5 which are fastened. to the standard. The latter has a swivel connection at 6 with an axle? on which are mounted. road Specification of Letters Patent. 4,fipplicatlicim filed ugnt 4,1906. Serial No. 329,192-

the auxiliary frame and its ends passii'ig;v

through plates 100 secured to the outer sides of the mainframe, said plates embracing and.

coni'ining the auxiliary rame. @n each side of the body are pivoted nuts 14 into4 whichv are threaded screws l5 pivotcd to the auxiliary frame il. One of the screws has a crank lfor turning it and the two screws. are connected by sprockets 'i7 and chain 18 so that they will turn in unison, the two screws being located at corresponding points on opn posite side members o the two frames. Rctation of the screws causes the non-connected portions 'of the ramesl and 1l to be pushed apart or drawn. together, and vthereby .the pivot l0 is raised orlowered respective, r, so as to elevate or depress the rear end of the in clined body. When the`parts are in the pofv sition shown in Fi 1, the body has its greatest inclination an such inclination is diminished and the 'l the frames 1 and 1l, as will be readily under'- stood. g

The lower end of theinclined hodyniay be made to rest directly on,tlie ground near the wheels 8 and to which is connected a drawd ower end raised by separating This conveyer is a box-like carriage, shown 'in detail in Fics. 5 and havin su ortindV ['5 kf* wheels Z0 which run on metal rails 2] ofthe main frame longitudinals 1. As sliown'iri Fie. 9 the convever has on its sides fiancee 22 D l YD which extend under the rails and so prevent possibility of the carriage jumping ofi the track. i 1

The conveyer normally ,resides inthe position shown in full lines in Fig. 2, wherein it may' receive `loads of earth brought to it by loose on the shaft 29, and l'inally auf-'ay from the apparatus under one oi the two 'guide puileys 30 on either slde of the-machine.

The rope may be hitched to a draft animal or it ,may also be connected with lioistmgem gine, and it may be led away from either side .IQ y

ofthe apparatus, as may be most convenient. 3l' is .a rope connected to the rear end of the .scraper by which the latter may be drawn vbaolf. It Will be seen that the serapei'is not 'constrained to travel in. any speoitied path, but may be placed in any position and drawn directly ltoward the elevating apparatus by the drive described.

The elevating carriage i9 has a bail 32'- to Io which is connected a rope 33 passing over a guide pulley 34 at the top ot the inclined liody, .andthenee `armind a drinn 35 to which it is seeured and which isitseli." fastened 'to thelshatt 29'. A pulley 36 is also fastened yto fthe shaft 2 9, randreceives a. rope to which oonneeted aoonnter-weight 37 which partially balances the weight ot the oarri er 19 when empty. l

.while the slot 412 allows the dumping device olutoh-disconnecting direction. Thereupon the hoisting drive for tho earl-.inne is diseonneeted and the latter is tree to return by gravity. Before this return happenshowever, the contents of the carriage are dninprd by the following ineens:

Referring'to Figs. 5, (i and 7, it will be seen that the bottom of the oarrier l2) is ooinposed ot'I two doors; 5l 52 which are hinged nonioprposite endsot the earring-e so :is to 'open downwardly, and when closed, to over the entire bottoni of the carrier. The door' 5l has arms 53 at its ends which aiieoiiiieoted by links 54 with the swinging edge 'olf' the other door so as to eauso both to open or olos'e simultaneously. Vhen the doors are closed, latches 55 take over projod 'ons on the door 52, and 'thereby' .hold the latter door shut, door 5l being` held by the links and Springs 5? tend to hold tho lo tehes lWhen the (anriingre is in engaging position. raised to its most elevated position, pins ,o on the inclined traine engage the late-hes o end hold them bank, thereim disongnging thorn trein the projet-.tions :36 und allowing.r the doors to open. Thereupon the material is discharged. On return of the enrriege, the doWn-l'ianging door 51 engages rollers 5t.) on :t traiisverse shait 60, and is raised thereby into closed position. In so risiiig, door Si also closes door 52, and so lifts it above the Upon being closed the doors are immediately eanght by the spring lat/vlies which were held against stops Gi on the sides of the Carriage. .f the latches have inclined faces on their lower ends, they are displaced' by the projections :5G when the doors close.
