ANDERS ANDERSON, OF GARNET, MICHIGAN.

LOG-LOADER.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed June 16, 1913. Serial No. 773,974.

To all whom it may concern Be it known that I, ANDnRs ANDERSON, a citizen of the United States, residing at Garnet, in the county of Mackinac and State of Michigan, have invented certain new and useful Improvements in Log-Loaders, of which the following is a specification.

This invention relates to log loading apparatus designed chiefly for use in removing logs from streams to the bank and v1ce versa and for loading them onto cars, and the primary aim of the invention is to pro vide means for winding and paying out the hoisting cable, which means may be employed also for the purpose of swinging the boom after the log has been elevated from the ground.

Another object of the invention is to provide means for automatically taking up the slack in the hoisting cable as the boom is swung around from one side to the other, the hoisting cable constituting the means provided for also swinging the boom.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of the log loading apparatus embodying the present invention. Fig. 2 is a top plan view thereof. Fig. 3 is a side elevation on an enlarged scale. Fig. 4 is a vertical sectional view on the line 44 of Fig. 2. Fig. 5 is a vertical transverse sectional view on the line 6-6 of Fig. 2.

Corresponding and like parts are referred to the following description and indicated in al'l the views of the accompanying drawings by the same reference characters.

In the drawings, the loading apparatus is illustrated as mounted upon a suitable baseframe, the side sills of which are indicated by the numeral 1 and may be supported directly upon the ground as shown in Fig. 3 or within an especially constructed car, as shown in Fig.1.. The side-sills 1 are connected by a number of cross-beams 2 and upstanding from the sills are spaced uprights 3. These uprights are located at the for ward end of the frame and constitute the mast for the boom. .Longitudinal beams 4 are supported upon the cross-beams 2 and upstanding from the beams 4 are uprights5 which are connected by beams 6 with the uprights 3, as clearly shown in F ig. 3 of the drawings. Mounted in suitable bearings 7 is a vertical shaft 8 and fixed at the upper end of the shaft is a turn-table 9 provided throughout the major portion of its periphery with gear-teeth 10. In its plane portion of the periphery of the table 9 is formed with a recess 11 and the said periphery of the table is further provided with a flange 12 which overhangs the teeth 10. The boom is indicated by the numeral 13 and at its lower end is secured to a sleeve 14 fixed upon the shaft 8 near the lower end thereof. The boom 13 extends upwardly at an angle from the mast 3 and is received within the recess 11, as clearly shown in Fig. 2 of the drawings.

The numeral 15 denotes a pulley which is mounted in a box 16 supported for swinging movement upon a pin 17 at the upper end of the mast 3. A yoke 18 is connected to the box 16 and is provided with a hook with which is engaged one end of a guyrope 19 attached at its other end to theboom 13. A guy-rope 20 is connected at one end to the upper end of the boom and at its other end to a hook 21 upon the said box 16. Mounted in a bracket 22 upon the turn-table 9 is a pulley 23 and other pulleys 24, 25, and 26. are mounted upon the table as shown in It will be observed that the pulley 23 rotates about a horizontal axis, whereas the pulleys 24, 25 and 26 rotate about a vertical axis, and it will further be noted that the pulley 23 is located relatively near the center of the turn-table, whereas the other pulleys are located near the periphery thereof.

The hoisting cable is indicated by the numeral 27 and is trained over a pulley 28 at the upper end of the boom 13, over the pulley 15, beneath the pulley 23 and around either the pulley 24 or the pulley 26, de-

pending upon the direction in which the turn-table is to be turned. It will be noted that all of the brackets in which the pulleys are mounted are open brackets so that the cable may be readilydisengaged from the pulleys and rearranged. A cross-piece 29 is mounted upon the beams 6 and mounted in brackets 30 upon this cross-piece 29 are pulleys 31, around either of which'the cable 27 may be trained, depending upon whetherit is first passed around the pulley 24 or the pulley 26. p.

The cable 27 is wound upon a drum. 32

which is fixed upon a shaft 33 mounted in suitable bearings 34 upon the uprights 5. At this point it will be noted that the drum 32 is displaced rearwardly with respect to the turn table and that consequently the cable 27 is led rearw'ardly from the table in winding it about the drum. For a purpose to be presently explained a gear 35 is fixed upon the shaft at one end of the and a sprocket-gear 36 is fixed upon the shaft at the other end of the drum. A shaft 37 is mounted in suitable bearings 38 upon the said uprights 5 and fixed upon this shaft is a clutch member 39 provided in its opposite faces with conical clutch surfaces 40. Clutch cones 41 and 42 are slidably mounted upon the shaft 37 and rotatable with the cone 41 is a pinion 43 which meshes with the gear 35, the cone 42 being provided with a sprocket gear 44 about which and the sprocket gear 36 is trained a sprocket-chain 45. The clutch cones 41 and 42 are pro-. vided between their body portions and their pinions and gears respectively, with grooves 46 which receive the forks of brackets 47,

which brackets serve to prevent longitudinal movement of the clutch-cones upon the shaft 37, although permitting of longitudinal shifting of the said shaft so that the member 39 may cooperate with either of the clutch cones for the purpose of clutching the same for rotation with the shaft. At one end the shaft 37 has secured upon it spaced collars 48 and mounted in a bracket 49 upon the adjacent beam 6 is an angle lever 50 having'a forked arm 51 engaging with the said shaft 37 between the collars 48. Connected to the other arm of the angle lever is a rod 52 which extends forwardly and is operatively connected with a hand-lever 53 which may be rocked so as to impart rocking movement to the angle lever whereby to shift the shaft 37 and bring the clutch member 39 into clutch with one or the other of the clutch cones 41 and 42. It will now be apparent that when the shaft 37 is rotating and the clutch-member is in intermediate position neither of the gears 35 or 36 will be driven but if the clutch member 39 is 50 shifted into engagement with the clutch cone 41 then the drum 32 will be rotated in a direction to wind up the cable 27. On the other hand should the clutch member 39 be shifted into engagement with the clutch cone 42 the drum 32 would be rotated in a reverse direction and the cable 27 would be paid out. The shaft 37 is driven through the medium of a chain 53 trained about a sprocket 54 thereon and a sprocket upon the 60 engine, showing of which has been omitted. A shaft 55 is journaled in suitable bearings upon the beams 6 and fixed upon this shaft is a clutch member 56 having a peripheral braking surface 57 about which is fitted a 65 brake-band 58. The band 58 is adapted to drum 32 be contracted about the periphery of the clutclrmember 56 by means of the crankend 59 of a shaft 60 which may be rocked through the medium of a hand-lever 61. Slidably fitted upon the shaft 15 andfreely 70 rotatable thereon is a clutch-cone 62 designed for co'ciperation with the clutch member 56. This cone 62 has its hub provided with a groove 63' to'receive the usual shifting yoke 64 designed to be actuated by a lever 65 mounted beside the levers 53 and 61. The hub of the clutch-cone 62 is also provided with a sprocket gear 66 about which and a similar gear 69 upon the drum-shaft, is trained a sprocket chain 68. The shaft 55 so also carries a bevel pinion 69 adapted to mesh with bevel gears 70 and 7 0 at the lower end of a shaft 71 mounted in a suitable bracket upon one of the beams 6. Fixed upon the shaft 71 at the upper end thereof is a pinion 72 which meshes with the gear-teeth 10 of the turn-table 9.

-When the cable 27 is trained over the pulley 24 the pinion 69 is to be placed in mesh with the gear 70 and when the'cable is trained over the pulley 26, the gear wheel 7 0 will be placed in mesh with the pinion 69, the gear 70 having been shifted upon the shaft 71 to position out of mesh with the said pinion. i

If the operator desires to lift a load without swinging the turn table, the brake band 58 is tightened upon the clutch wheel 56'and the clutch member 62' is shifted out of clutch with the said member 56 by means of'the lever 65 after which the drum 32 is rotated to wind up the cable. When the load has been lifted to the desired height and the operator wishes to carry it around to position for unloading the brake band 58 is 1 5 slackened, the clutch member 62 having been first shifted into clutch with the member 56. The weight of. the load will then cause the turn table to rotate and as it rotates power will betransmitted through 1 the shaft 55 and gear connections 68 and 69 to the drum 32 so that the drum will take up the slack of the cable and not permit the load to lower. After the load has beendeposited and it is desired to return the table to its original position the clutch member 62 is thrown into clutch. with the member 56 and the drum32 is. set in motion. Power will then be transmitted through the gear connections 69 and 68 to the shaft55 and by way ofthe pinion 72' to the said table.

Having thus describedthe invention what is claimed as new is 1. In apparatus of the class described, a swinging. boom, a turn-table arranged to turn, with the boom, a winding drum displaced'with relation to the turn-table, a pulley upon the turn-table, a pulley upon the boom, and a hoisting cable wound upon the drum and threaded about the pulley, the
