To all whom it may concern:

Be it known that I, Lnnor Pnmmn Currrma, a citizen of the United States of America, residing at Deer Lick. in the county of Greene and State of Pennsylvania, have invented certain new vand useful Im rovements in Excavating-Machines, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to excavating inuchincs, particularly designed for use on land and commonly known as u steam shovel.

My invention aims to rovide a portable excavating machine for nil kinds of excavating and rehundling of material. The machine can be used for loading cars., for widening cuts or embankmcnts, cutting down grades, cleaning ditches, digging canals,

uilding u railroad embankments, and so on, througi the constantly multiplying variety of uses.

The invention further aims to provide an attachment for on ordinary traction engine such as is used for threshing and contract work. It is o. well known fact thata large number of traction on 'nes are merely used for threshing or fodlfdr shredding five or six weeks in a year, and it is in view of this fact that I intend to utilize a traction englue in connection with my invention for grading streets, ditching, making shallow cuts, and working in confined places where ordinary machines could not be used with any success.

To this end, I have devised a )ortablo machine, wherein positive and re inblu means are employed for manipulating the show] or scoop of the machine as though the some were manually handled, said means hein compactly nrrungrd and within easy room of an operator positioned at a safe location upon the machine.

My invention cmlmdics certain novel dctnils of construction thut will be hereinafter described and thou specifically pointed out in the appended claims.

In the drawings, Figure l is a side ch-vution of my machine, Fig. 2 is an cnlnrgcd elevation of u portion of tho mnchiuc portly broken away and partly in section. Fig. ll is a. front elevation of the sumo portly broken away and partly in suction, Fig. 4 is u dcluil scchonul vicw oi u clutch forming purl of the o wrutiug mcclmuimu of the machine,-

- and big. I; is u pluu of the machine as illustrated in Fig. 1.

To put my invention into practice, 1 .provide a suitable frame work with a .p'ivotcd jib or crime having a movable shovel or bucket. The frame work is adapted to be attached to the forward end of a traction engine ia'nd the mechanism for swiniing the lb or crane raisin or lowering thes ovel or ucket thereofgafi for drug mg said shovel or bucket, to scoop up a m is operated by the traction e1 attendant th'ereo In ortler thatfmy invention can be clearly understood, the detail construction entering into the some will be described under the following captions: The attachment u-ndthe frame work thereof, Jib or crane and the operating mechanism thereof, Shovel or bucket, and the operating mechanism thereof, and The general operation of the oxcavator.

The attachment and the frame work thercof.--The attachment comgrises longitudinal ch'ntmel bars 2 connects by a lower sill 4. The bars 2 are adapted to be connected to a traction engine 1 by a strap 3. Mounted nor: the bars 2 adjacent to the forward -en-s thereof are transverse beams 9 and 10. Connected to the beams 9 and -10 are two sets of uprights 1.1 and 12 having the upper ends thereof connected by transverse braces 18 and 14 respectively. The sets of'upgi hts 11 and 12 are tied together by ongu r disposed side stringers .15, having the ower ends thereof fixed upon the rear ends of the bars 2. The tronsversc braces 13 and .14 are connected by a longitudinal central hem-lug 16, and the beam 10 is provided with a forwardly extending oeutrnl hearing 17, said bearings 16 and 17 being connected by vertical frames 18. The uprights 12 are connected by transverse braces 19 and 20, for a purpose that will hereinafter appear. In connection with the attachment, suitable jacks 21 and anchors, (not shown) can be used for fixing the atluchmout and engine to a roudbed or truck upon which it travels, whereby the attackmcut can he tilled when the cxonvnlor is in operation.

J-ib or'crmu: and flu: operating wm-nlmmlsm Uu'roof.--'ll1c jib or crane comprises a must maulc of two uprights 22, u boom made of two lifillllll-l 23, and diagonally disposed humus 9.4-, connecting the outer ends of the booms .23 to tho lower curls of the uprights 22, said uprights uud booms providing u trine and controlled by on till upon a transverse brace 40 carried by the stand the strains and stresses to which it is subjected when the excavator is in operation. The upper end of the mast is provided with a bearing block 25 fixed between the upper ends of the uprights 22 and the rear ends of the beams 23. This bearing block is connected to the forward end of the bearing 16 bv a in 26. The lower end of the mast is title with a bearing block 27, said block being secured between the lower ends of the beams 24. In the sill 4 is mounted a socket bearing 28 and loosely mounted upon said bearing and surrounding a socket portion thereof is a bearing block 27, serv- 1 ing functionally as a king bolt to pivot. a jib or crane. To swing the jib or crane 1p :1 horizontal plane, I provide the bearing block 25 with a large horizontal wheel 29, i said wheel being fixed to the boom of the 1 jib, as at 30. Secured to the periphery of I the wheel 29 and adjacent to the boom of a crane are the ends of a sprocket chain 31, 5 said chain extending rearwardly over a sprocket wheel 32, mounted upon a vertical shaft 33, journaled in a bearing 31 carried centrally of the brace 14, said shaft also being journaled in a brace 19. Upon the shaft. 33 at the lower end thereof is mounted a gear wheel 35 adapted to mesh with a worm 6 mounted upon the longitudinal shaft 37 jonrnaled in a bearing 38 swiveled u on the brace 19. The forward end of the s aft 37 is journaled in a bearing 39 fulcrumed anglplnr structure of suflicient rigidity to i wit uprights 11. The bearing 39 is pivotally connected by a link 41 to a bell crank lever 42, which is pivotally connected to the upri ht 11. By movin a lever 42 the rear end 0 the shaft 37 can fie moved, and this rear end of the shaft is rovided with a friction clutch wheel 43 a apted to be driven, as will hereinafter appear, for swinging the jib or crane in a horizontal plane. The for ward sides of the uprights 11 are provided with transverse alining bearin s 44 for a main operating shaft. 45, said siaft having a belt wheel 46 for a belt 47, this belt being driven by the hell wheel of the engine 1. Mounted upon the shaft are two clutch wheels 48 and 49. min )ted to be engaged by I a frictional clutch w incl 43. for swinging l the jib or crane. The latter clutch wheel l 49 is adapted to be engaged by a clutch member 50 mounted upon the inner end of a i spool 51, said spool being slidably mounted upon the shaft 45 and adapted to rotate tlu-rcwith. The spool 51 is provided with a sprocketwheel 5:! and with u loosely bold hand M for shill-in said spool upon the shaft 45, said bnnil being conuecttul by means of u link M to u boll crank lover l'ui, pivoted upon the uprights It at the right mud side of the machine. This purliculm' upright. is provided with a rack fill for lochwifh the clutch iug the lever 55 and either holding the clutch member 50 in or out of engagement wheel 49.

Shovel or bucket and the operating mechanism fIn-r-of.-'Ihe beams '23 of the crane boom support a guide 57, said guide being, loosely mounted on u pivot pin 58 journaled transversely of the beams '23. Movably mounted in the pivoted guide 57 is a shovel or bucket arm .19 and to the lower end of this arm is scoured a shovel or bucket 60 of the ordinary and well known type, having a trip drop bottom 61. The arm 59 is provided with a rack 62 adapted to mesh with a pinion 63 mounted upon the pin 58. One end of the pin is provided with a s n'ockct wheel 6-1 am] over this sprocket wheel passes an endless sprocket chain 65, said chain also passing over the sprocket wheel 66 mounted upon the end of the shaft 67, journalcd in the mast of the crane. Upon the shaft (37, between the uprights 22 of the crane mast is a gear wheel 6b adapted to mesh with a worm 69 mounted u on a vertical shaft- 70, 'ournaled in the soc ct bearing '28 and the ieuring 71 carried by the frames 18. ll )on the shaft is mounted a sprocket whee 72 and over this sprocket wheel extends a sprocket chain 73, which also passes over a sprocket wheel 74, mounted upon a vertical raft 75 having the lower end thereof loosely jonrnaled in the bearing 17. The upper end of the shaft 7.1 is jonrnaled in a ivotcd bearing 76, carried by a transverse Jrace 40. This pivoted bearing 76 is conncelcd by a link 77 to a lever 78 pivotally mounted upon the upright 11 at the right hand side of the machine. The 11 )per end of the shaft 75 is u'ovidcd with a rictional clutch wheel T9 at opted to engage either of the clutch wheels 43 or 49.

The jib or crane head is provided with u revolnbhsheave $0. and attached to said head is a chain or cubic Rt extending downwurdlv around a sheave 52, carried by the shove or bucket 60. This chain or cable uxtvndsupwardly over the sheave 80 and 0W! :1 rcvoluhle sheave H2 supported at. one side of the jib or crane by bearings 83 and H-l. 'lhr rhaiu or cable extends rmlmvardly over a sin-ave Sit jourludcd in the uprights :31! of the rrnnc must. The chain or cable then passes under a sin-aw HI; jnurnnled lirlwccn tho i'rmncs l8 and upwardly to a drum mounted u mu a shaft 9. journalrd upon the uprights ll. 'lhu chum or cable is attached to this drum and is adapt- (ti to wind (hereon for dragging the shovel Um of the heads of the drum 8? conforms to u sproclu-l wlu-ol 8!! and over this sprmtlul wheel and the sprocket wheel 5!. is mounted an endless sprocket chain lltl.

,' description. it will be observed that t u h illtl till revs i2, 5-- aud 78 are located upon the ri 'ht hand side of the machine, and in order tint these levels can be easily mani minted, the uprights 11 and 12 are provi ed with an outwardly extending platform J1 u on which an operator or machine atten ant stands for moving the jib or crane and the shovel or bucket: carried thereby. Assuming that the engine 1 has been placed in operation, the rotary movement will be 1mparted to the shaft 45. When the lever {:5 hi moved to place the clutch member in engagement with the clutch wheel 49, the drum 8? will be rotated to wind the chain or cable 5t thereon and drag the shovel or bucket. (it) into the material to be scooped up or excavated. Simultaneous with this movement. the shore] or bucket can be raised or lowered. This is accomplished by manipulating the lever 78 to shift the bean-i 39 and place the wheels '79 into frictlona enga cment with the clutch wheel 49 and 48.

fter the shovel or bucket has been loaded and raised to clear the cut. or pile from which the material has been removed, the jib or crane is swung to place the shovel or bucket over it than or a car for receivi the contents of said shovel or bucket. ThlS is accomplished by movin the lever 42 to shift the bearing 39 and place the wheel 43 in frictional engagement with either of the clutch wheels 48 or 49, according to the direction in which the jib or crane is to be swan".

I reserve the right to provide the engine 1 with a suitable canopy for )mtectiu the engine and the operating mac ianism o the machine.

While in the drawings forming a art of this a plication, there is illustrated t 1e preflllvtP embodiments of my invention, I would have it undelstood that the details of construction can be varied or changed as to the shape, proportion aiid manner of assemblage without departing from the spirit of the invention.
