Patented Sept. 30,. 1947 UNITED STATE s 1 PATENT oFFlcE 2,423,085V l Locr Hors-rma -AND HAULING naar William M. Largeu, Roanoke, Va. application october c5, 194i,`serial No. 560,316 y This .invention relates to log hoisting Aand haul Y l ing carts, and has more particular reference to atwo-wheeled trailer type such as is adapted 'to b'e hitched to a tractor orother powering vehicle, fand the primary objective 'of the invention is to generally, specifically and otherwise improve uponvr known marketed and patented log wagons, this in a manner to better serve 'the aims and requirements of manufacturers and users alike.

The purpose of this .log 4cart er trailer fis to lift saw quickly becomes dull'ed, and the `sawmill must be shut down for sharpening the saw a number of times each shift. By carrying the log with only one end "scraping along the ground, it is pcs-v sible vto keep theA log almost 'entirely'clean land the reefs'harpening period, twenty minutes, isf

eliminated entirely. except 'du-'ring the noon rest time,:f=an'd:"at the end of the shift. If the saw Iis not dulled -lcyfdirt, the whole sawing operation is speeded up considerably, and several hours sawing time 'saved duringeach shi-it. f

- One phase of apparent novelty has to do with the adoption and use of a well balanced, simple,

two-wheeled cart characterized by a horizontal frame, a perpendicular frame vattached to and rising vertically therefrom, andan upwardly inclined, rearwardly projecting boom attached to said frames and provided at its rear hoisting 'and hauling zend with 'a `cable-acommodation sheave.

Further novelty is predicated upon the wheelsupportedV axle, this provided with a motiontransmitting, fixedly mounted gear meshing with a power take-off gear on a suitably mountedshaft, appropriate operational facilities being provided between said axle and shaft, and said shaft carrying abrake-equipped drum for cable winding and reeling purposes.

In carrying out the preferred embodiment of the invention; IV have levolved and produced anaclequate vand expedient structural assemblage which is comparatively simple, substantially fool-proof,

sturdy 'and reliable, and otherwise constructed and -balancedto achieve the desired Vaims in `a practicable and reliab'lernanner.

Other features andfadvantages will becomemore readily apparent from the following description andtheaccompanyng illustrative drawings.

However, the Amachine, becausefof the ratchet and pawl action, may b'e backed EWithout 'the axle turning,l and also be* cause of vthe' ratchet `and pawll arrangement,I the machinemay be pulled forward 'and turned sidewise, al1-owing the wheels te travel the-necessary different Aspeeds to make the turn. As the Imachine is pulled forward, 'theaxle thus turnsa gear wheel mounted on theraxl'e and this in turn drives 'another mesh'ed gear wheel, which is `f-ree running on another axle or shaft, attached to the frame, above rand in front of the wheel Referring now tothe r'drawings by distin'guis e ing .reference numerals and referring .-flrs't to Figure 1, it will be seen that the structure come prises ahor-izontal frame 8 'of "the top .plan lcon'- guration seen in Figu're'z. the rear rectangular portion 'of-'said frame fi's a perp'endieular complemental frame 9 attachedto andY ris ing perpendicularly ,from thehorizortalffranie. 0n Vthei crown portier-itis fan :accommoiation block l to which an I-beam Il forming a boom is attached. 'I'his boom is suitably inclined and has its forward end attached to the corresponding end of the frame and has its rear end provided with an adapter bracket I2 well over and beyond the rear end of the frame and carrying a pulley or sheave I3. The frontal portion of the frame 8 is provided with a tongue I4 and an appropriate hitchl I5 attachableY tothe tractor connection shown j in I dotted lines in Figure 1. The rear axle vI6 "(see Fig. 6) is journaled for rotation in bearings provided in the side mem bers of the frame 8 and the projecting outer the cable so that the log grabs can be set in the ends have traction-type, ground-engaging wheels I1 loosely mounted for rotation thereon. In

this connection, it will be observed that a ratchet pawl I9 (see Fig. 7) is pivotally mounted on 4 so that the main pulley drum cannot revolve and allow the cable to run out or olf of the drum. I-Ie disengages the clutch wheel from the gear wheel on the same axle so that the revolution of the cleated wheels is not transmitted to the pulley drum. Or, in other words, the machine is allowed to run entirely free. The operator then proceeds to the place where he desires to pick up the logs, and backs the tractor and log cart -to a point as closer as he can to the log or logs he desires to haul to the sawmill set. The operator then releases the hand brake arrange- `ment so that the drum runs free, and pulls out log orv logs he proposes to haul to the sawmill.

`The operator then remounts and sees that the hand brake is not set. He then pulls the con- Ytrol cable so that the lugs of the pulley wlheel the hub of the wheel so that when lthe machine* is pulled forward by thetractor, the axle is thus turned. This pawl and ratchet arrangement also provides for the aforementioned back-up and differential action previouslyset forth.4 While considering Figure 6, it willebe vobserved'that a suitable gear 2llis xedlymountedon the axle, this being thefpowertransmission' gearv which serves in a manner to be hereinafter set forth. Attention is now conveniently.v directed to Figure 4 which discloses the horizontal :power or motion take-off shaft 2| ljournaled in bearings 221 and having at oneend an idling gear 23 in mesh with theV gear ,20. A reeling andk winding drum fof suitable.; construction 24 lis pinned or otherwise keyed on the central portion ofV the shaft ZIfor rotationtherewith.

During the hauling otheiilogsirfrom thesite where cut to thesawmill` set; thewlog wagonis pulled by a tractor-.Knot shownlian'd its'` operation is as follows: 1 f

The tractor operator reache-sffoverthe of hisseat and sets the control tothe :brake 'leverf will become engaged in the gear wheel, thus transmitting all motion from the cleated wheels to the cable drum. He thenV puts the tractor in motion, and the weight of the logs on the cable and pulley causes a great deal of traction on the cleated wheels, which, as soon as they start, of course, cause the dr-um to revolve and this causes the cable to be wound up on the drum. The operator drives the tractor and wagon forward far enough for the front end of the dragged logs to be Well olf of the ground. He then disengages the clutch wheel from the gearr by the control on the front end of the log wagon. At the same time, he sets the hand brake so that the pulley drum cannotV revolve, and the logs now being securely held at one end well olf the ground, the operator proceeds to the sawmill set, dragging thelogs behind the log wagon, with only one end of the logs draggingon the grounds,

It has been found that the weight of the logs Y transmitted through the. cable to the sheave Wheel, and from there through the boom and frame to the cleated wheels provides simple traction so that. the drum always revolves when the controls are properly set, and the wagon is pulled forward, thereby winding up the cable and so dragging and lifting the logs being hauled.

'Novelty is thought to reside in the horizontal and vertical frames 8 and 9 suitably wheel supported andv theinclined boomV II, this extending well to the rear of the trailerand Wheels on` said .trailer to provide the requisite accommodation base and elevation for lifting` the log ends to the desired points fordragging purposes.

Additional novelty is predicated on the shaft, drum, gear and clutch assembly emphasized in the construction shown in Figure 4.
