"ADJUSTABLE MOTOR DRAFT ATTACHMENT.
Specification of Letters Patent.
, PatentedDec. 1,1908.
Application flled June 17, 1908. Serial No. 438,899,
which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. 1
This invention is designed for connecting" a road englne or other suitablemotor to a road grader or scraper,
The object of the invention is to provide a strong, and eflicient-draft attachment which shall 'beadjustable to allow the engine or motor to travel-on the central or best part of the road while drawin the road grader or scraper along on one si e of the road-bed for ditching the road or for scrapin the side of the road-bed. And to that en the invention consists in thenovel construction of the motor draft attachment hereinafter dein the annexed claims. I
In the, accompanying drawings, forming part of this application, Fi ure 1 is a plan view of a motor draft attac me'nt embody, ing my invention; and, Big. 2 is a side view of the same. Y
Q Arepresents in dottedr'lines the rear end of a road engine or motor which may be of any suitable construction adapted to propel a road -scraper or grader;
B designates the front end portion of one ofthe numerous different styles of roa'd scrapers, the detail construction of whichis immaterial to my invention.
The essential feature of my invention resides in the means for connecting the road scraper to a road engine or motor in a manner which allows the engine or motor to travel in the center or on the best portion of the road while propelling the road'scraper at one side of the road bed. And for this .purpose the invention consists in the novel construction and combination Jf the component parts of the adjustable mptor draft attachment, which is as follows, to wit: The forward portion of the scraper frame B is secured to the steering frame D- (shown in Fig. 2) mounted on the axle c of the carrying -wheels 0. The frame D is composed of a central longitudinal beam -a', which is employed in place of the ordinary tongue of the machine and is fastened to the underside of the fifth wheel b and rigidly sustained at right angles to the axle .--ct by means'of the usual braces d'd-.
firmly attached two forwardly diverging their front ends by means of transverse bars -w. The arms have fastened to their front ends, plates, f* which sustain belates. Said sheaves are grooved circumferentially for'the purpose hereinafterexplained.
''h represents a shaft which is mounted on the beam a and sustained at ri ht angles thereon by means of brackets bfastened to the tops of the rear ends of the arms -.eeand formed with journal bearings receiving the shaft h through by means of braces j fastened to the rear end of the beam a and formed at their front ends with rings vk--o embracing the ends of the shaft. 1
-Z denotes a worm ear which is rigidly secured to the shaft and engages a Worm m pivotally connectedat nn-- to the adjacent bracket i attached to the beam a. The worm has fastened -to it a shaft -o which is inclined rearwardly and is provided at its free end with a crank -o which is disposed conveniently To the sides of the central beam-aare tween them the sheaves -g pivoted to the arms -ee, connectedto each other at them, The shaft -72, is further sustained o the shaft h'*-' are suitably fastened two'sleeves r-r u on which are wound in opposite directions t e rear ends of chains sswhich traverse the grooved sheaves -gg and are fastened at their front ends to the draft-pole P which is pivoted at,
its rear end as shown at t to metal straps" its steering frame and road engine of a draftpole pivotally connected at its rear end to the said steering frame, and provided on its front end with means for coupling it to the road 1. The combination, with a road scraper, 1
' engine, and means for adjustably sustaining its steering frame and road engine of a draftpole pivotally connected atits rear end to the said steering frame and provided on its front end with means for coupling it'to the road said draft-pole at anangle in relation tothe line of travelof the road engine,
3. The combination, with a road scraper, its steering frame and road engine, of a draft pole pivotally connected at its rear end to the steering frame and provided on its front end with means for coupling it to the road enine, and means secured to the steering frame for adjustably sustaining said draft pole at an angle in relation to the line of travel of the road engine.
4. The combination, with a road-scraper, of a steering-frame secured to the scranerframe, a draft-pole pivotally connected at its rear end to said steering-frame and provided on its front end with means for coupling it to a road engine, sheaves pivoted to the said steerin -frame at opposite sides of the draftole, c ains traversing said sheaves and attac ed at their front endsto the draftole, and means secured to the steeringrame for operating the said chains.
5. The combination, w t a road-scraper, of a steer'in -frame secured to the scraperframe, a dra tole pivotally connected at its rear end to sai steering-frame and rovided at its front end with means for coup ing it to frame at opposite sides of the draft-pole, a a road engine, sheaves pivoted to the steeringrevoluble shaft mounted transversely on the steering-frame,'chains traversing the sheaves and attached at their front ends to the draftpole, and wound at their rear ends in opposite directions on. the aforesaid shaft, and" means for turning said shaft.
' 6. The combination, with a road scraper,
of a steering-frame secured to the scraperframe and formed with forwardly diverging arms, a draft- O16 ivoted at its rear end to the steering ame between the aforesaid arms and provided on its front end with means for coupling it to a road engine, sheaves pivoted to the front ends of the aforesaid arms, a revoluble shaft mounted transversely on the steering frame, braces attached to said steeringframe and formed with rings embracin the ends of the revoluble shaft, sleeves fastened to said shaft, means for turning the shaft, and chains trav ersing the sheaves and attached at their front ends to the draft-pole and wound at their rear ends in opposite directions on the aforesaid sleeves.
, 7. The combination, with a road scraper, of a steering-frame secured to the scraperframe and composed of a longitudinal center beam and forwardly diverging arms attached to said center beam, plates attached to the front ends of the arms, sheaves pivoted to said plates, a draft-pole pivoted at its rear endv to the front end of the center beam and provided on its front end with means for coupling it to a road engine, a revoluble shaft mounted transversely on the said steeringframe, braces attached to the steering-frame and formed with rings embracing. the ends of the shaft, sleeves fastened to said shaft, chains traversing the sheaves and attached at their front ends to the draft-pole and wound at their rear ends in oppositedirections on the sleeves, a wormear attached to the aforesaid shaft, a brac ret attached to the steering-frame, a worm pivoted on said bracket and enga ing the worm-gear, a shaft extending from t e worm, and a crank attached to said shaft.
