To all whom. itmfeg/ concern.' Y

Be it known that I, RICHARD F. DUDLEY, a citizen oi' the United States of America,

residing at Dudley,in the county of Lin-'- coln and State of lVisconsin, have inventedcertain new and useful' Improvements Log Loaders, of whichfthe following 1s a`Y specification. Y .Y

This invention relates to a log loader. Theobject ofthe present inventionis to providea simple, practical and. efficient' log loader of strong and durable construction designed for use in forests where trees-'are Vfelled and the branches yremoved 'therefromand the logs piled onrskidways from which they are loaded von. motor trucks or other` vehicles by the said log loader. l

Another object ofY thel invention is to provide a log loader of this character adapted to be easily manipulated and capable ofhav.- ing the derrick or frame from lwhich hoist-A ing mechanism is suspended racked from one side of a road vto the other to enable the log loader to be employed for loading logs from skidways at either side of the said road without. the inconvenience of turning the log loader around on the road.

With these andV other objects in view, the' invention consists in the novelrconstruction,

combination and' arrangement of parts hereinafter fully described, illustrated in the accompanying drawingsfand pointed" out in the claims* hereto appended, it being understood that various changes in the form,

proportion and minordetail's of construction, within the scope of theV claims, may be resorted to 'Without departing from` thel spirit or 'sacriiicinglany of the advantages of the invention. l

In the drawings in whichlike `characters of. reference designate corresponding parts in the several figures: ,y l Y Figure l is aV side elevation of. a log loader constructed in accordance with this invention Yand shown in position -for loading logs onf'a motor vehicle havinga trailer attachment.

'The transversebars ormembersy l are provided withv rack bars '5' suitably se'- curedl to the upper acesf'of` the said bars ory members -4 and having extended terminalportions which arecu'rved upwardly and in# 85 Y wardly forming substantially semicircula'rv arms-'6 whichv constitute stops -and provide seats for pinions or gears "14 which ineslr With the vracks ofthe' transverse ba-rs as'li'ereinater fully explained. 'The'curved armsQO 6 are equipped'with pawls or 'dogs`8 con` neoted by suitable hinge jointsgf?V with the terminals of the* armv 6 and` adapted'toen--v ff- "i gage the pinion'siorgears` 14E, for locking the samel againstrotary movement as illustrated` in Figure 5 of the drawings. i 1 v v Mounted on the rackmernber 5 is the der A rick frame 9' composed of oppostely fin-1 clined sides` or frame members and horizon-Y tal' connecting' braeesl'lifandf 1.2', the-brace lll 1.00

being located at' apoint'intermediate t'life'` ends of the derri'ck'frame a'ndthe brace 12"" being arranged atzthebottomfof the.cle'r'rifc'l` rameias clearly illustrated inv Figure@` of the drawings. 'Theshat'l extends through 105 the bottoml brace 12 and alsothroirgh the lower ends of the: trame members of! the derriclrrame 9v and-.the pinionslo'r gears-14 are suitably fixed to the end portions of the shaft 13 which 'is radaptedV to 1 rotate to per-- mit theV derrick frame to beracked from one side of the base to the other when the base is arranged in ahorizontal positionas illustrated. The ends of the shaft 13 are square and are adapted to receive suitable meansfor rotating the shaft for racking the derrick frame along the transverse bars of the base and any suitable means may be employed for this purpose. When the log loader is in working position as illustrated in Figure 3 of the drawings, the base wis, swung up,- wardly to an inclined position contiguous to the kderrick frame and thegears rest inthe curved arm 6 at the bottom of the inclined base, a board *14"*V or ,the like being preferably placed vunder the derrick frame to prevent ,thesame from sinking into the earth.'y

The pawls of dogs engaging in the pinions or gears 1a will hold `t-he gears against rotation and the :base securely Qin the Vinclined position shown in Figuref. A s

The upperYV ends ofthe inclined side members of the derrickframe can be secured together leither by means o'fa ring orfby the i cap piece 10 as shown, the pivot 10aprojecting upwardly longitudinally of the derrick frame and receiving a collarv 15 of. an approximate L-shaped bracket 15'LL extending outwardly and downwardly from the sai pivot and having a sheave 16 pivotally Vsuspended from itby a suitable hanger 16a.'

VThe bracket is free to swivel on the pivot 1()a whichalso has mounted on it a collar 17a of a hanger cable vattaching member 17 located above and resting upon the collar 1 5 il winch ofthe drum extends upwardly thereand adapted tol swivel on the said pivot 10ft.

Hanger cables 18 forming guys are secured at their upper ends to the member 17 and are designed to be secured at their lower ends to a tree or otherwise anchored in the ground. The retaining collar 19- is suitably secured to the upper end of the pivot 10 'for retaining the collars 15 and 17 a thereon.

The cable 2O whichis wound around the from to the sheave 164 andis arranged thereon and Vit extends downwardly therefrom and is equipped with a suitable lower cabling Y ydevice 20a which may Y consist-fof branch ,f cables provided with terminal hooks 21 for engaging the ends of a log as illustrated in Figure 1 of the drawings The cable 20 Ais adapted to be wound; aroundA the drum of the winch for sliding the logs upwardly along an inclined skidway l22and thenceA onto the truck, the loading device-enabling the logs to be readily lifted .and `swung to the proper positiononthe truck for loadingfthe same. f

'When the log loader istransported from one location to another, the base is arranged in a horizontal position and the` derrick frame is rigidly connected .with the base by `shown in Figure 6 of the drawings.

Aopposite'side of the base. The brace is conl- Vposedo the two bars or members 23 having overlapping intermediate portions and provided at their terminals with suitable keep- Vers 24 of rectangular form and having base members arranged within them asv clearly The brace bars orimembers aresecured together n and held against relative longitudinal movement by a bolt 25 and thelower end'of the brace is secured by a bolt 26 to an ear 27 of the adjacent sill-side' member 3. The upper end of the brace is suitably secured at 28 tothe brace 11 or other suitable :tastening device on the derrick frame. Each ofthe sills or sidemembers 3 yof the base :is preferably provided with an ear or. attaching member 27 to enablethe derrick frame' to be yplaced at either side ofthe base. The ends of the sills or side members 3 are pref.- erably beveled at the lower faces at 29 to enable them to constitute runners to per-1 mit the loader to be readily moved over the ground from one location to another. In practise one man usually walks on either side of thelog loader holding the hanger cables 18 for steadying the structure while the same is being transported. What is claimed is: A1. A log loader, including a base and an inclined derrick frame extending upwardly at an inclination from the side ot the base, said frame being shiftable laterally to either side of the base to enable logs to be loaded at either side of a roadway without moving the log loader. c f
