rownn TRANSMISSION FOB nx'esvn'rrrre APPARATUS.
To all whom it may concern:
Be it known that 1, WILLIAM J. NEWMAN, a citizen of the United States,re'siding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements. in Power Transmission for Excavating Apparatus, of which'the following is a specification.
This invention relates more particularlyto the dragrope or cable apparatus used in connection with excavating shovels, to drag the shovel forward for filling the same, and to such other details of construction and arrangement of parts as willbe fully described and claimed hereinafter;
If a block and tackle is used with an excavating apparatus, and connected directly to the shovel, the
tackle ropes and one or both of the blocks are subject to being dragged. in the earth or dirt which'is being excavated, and will'soon become abraded and worn and consequently are apt to give considerable trouble. They are also'inconvenient in operation.
In order to provide an eflicient transmission device for operating the shovel, I have providedthe mechanism shown in the accompanying drawings in which Figure 1 is a side elevationoi an excavating apparatus provided with my im'proved transmission mechanism, the shovel also being shown provided with adjustable'guide-shoes; Fig. 2 is a top-plan view of the same, parts being broken away to show the'transmission apparatus; and Fig. 3 is a detail view showing one of the block-guides.
As shown in the drawings, 4 represents suitable skids or frame-work for-supporting the hoisting apparatus, this apparatus consisting in general, of a boom 5 and a shovel 6, with suitable means for operating the shovel to fillQraise and discharge the same,- :At one end of thefiame-work is a block [provided with'one or more sheaves, 8, this block being rigidly supported in the frame in any suitable manner; or if desired, the sheaves may be mounted upon a suitable shaft supported on the frame. This block is preferably arranged beneathlthe floor 9 of the frame-work so that it, and its cooperating devices, will be protected.'
' This block. is arranged at one end of a suitable guidecable 15, between the sheaves 16 way which consists of beams 10 having plates 11 secured thereto A second block 12 is .provided, on either side, with shoes or guides 13 which rest upon the plates 11.
the frame, and then up over a second sheave 17, mounted withthe boom'5. so that it is free to swing therewith, and then directly'to a suitable fastening on the shovel 6. The boom, with its swinging apparatus, is somounted that the vertical portion of the axis of rotation of the boom.

ber of times, does not receive as great a strain.
e shackle 14 is connected witha cable. 15 which leads under a guide-sheave or pulley 16 and 17, is along the Patented July 16, 1907.
The shovels is operated for filling by means of any ordinary or preferred form of winding drum, such as used with hoisting apparatus, and which is indicated on the drawings'at l8. cable or line 19 leads from the windingrlrumv 18 around the various sheaves or pulleys in the blocks 7 and '12, in the manner commonly known, the extreme end of the cable finally being fastened, as at 20 where it is shown secured to the block 7. The operation of the transmission mechanism 'will be readily understood from the drawings and the above description. When the shovel 6 has been lowered for filling, the winding drum 18 is turned to wind up the cable 19. As the cable is wound up,
the block 12 -travels along 'on the guide-plates 11 toward the block 7 as indicated in dotted lines in Fig.
l. This causes the drag-cable 15 to be drawn in, and
the shovel 6 to be drawn forward for filling. By means of this novel arrangement of transmission apparatus, a great mechanical advantage is gained and a small hoisting engine may be used for exerting an extremely 'heavy pull on the drag-cable 15. At the same time,
a light line may be used for the block and tackle portion of the apparatus, and a very heavy line can be used for the connection to the shovel, the latter line being exposed to comparatively rough usage and being subjected to a great strain, while the line on the block and tackle is protected and being multiplied a num- The shovel 6 is-preferably provided with guide- 'shoes 21, of the 'same general character as shown in my prior application, Serial No. 281,140, filed .-Octobe: 3, 1905; but in this instance, the shoes 21 are pivoted at 22 to the arms or frame 23, and at the rear end,
.the shoes are adjustably connected to the arms 23, as lor instance, by means of bolts 24, which pass through 'holes in the arms 23 and may engage one or the other of a series of holes 25 in the ends of the shoes 21. By
'means of this arrangement, the shoes may be readily adj usted as for digging in different kinds of earth.
Having thus described my invention, what l'claim is: y
1.- In an excavating apparatus, the combination of a frame-work, a block and tackle in said frame work, a winding drum connected with said block and tackle, and a. dragdlne leading from one of said blocks to' an excavating shovel or the like.
2. The combination of a frame work, a block rigidly secured in said frame, work a guidewziy in said frame work, a. second block movably mounted in said guidowny,
a line rove. around the sheaves in said blocks and [curling to a winding drum, and a second line connected with the movable block and leading to a shovel or other apparatus to he moved.-
3. The combination or a frame work, our or more sheaves or pulleys mounted in said frame work, a guidewriy in said frame work, one or more sheaves slidnhly mounted .to move along said gulllewny, :l cable or line wound from the stationary sheaves around the mmurht-r for said drag-line.
sheaves, one end thereof being rigidly secured and the other' end thereof leading'tofawinding drum, 2; second line or cable secured to thel'snp'port for the movable'sheaves and leading-to an excavating shovel or the like.
4. In an excavating apparatus,.the combination of a suitable frame-work, a block and tackle arranged within ,saidfram work in a protected position, a winding drum for winding up the line of said block and tackle, a.drag-line connected withpne of the block's, an excavating shovel with which said drag-line is connected, and wide-sheaves 5'. In'an excavating apparatus,.the conibfiationot a suitable 'frame work, a boom bivotally mounted on said frame work, an excavating shovel, means connected with saidboom for raising and dumping said shovel, a guidesheavetangent to the pivotal axis of said boom, a second guide-sheave below said first-named guide-sheave, a drag- WILLIAM J.
