DOUBLE RUNNER.

To all whom t may concern.'

Be it known that I, Jnssn E. CHnNE'rrE, a citizen of the United States, residing at Montpelier, in the county of Washington andfState ofrVermont, have invented certain. new and useful' Improvements 1n Double Runners; and I do declare the f ollowing-.to be. a full, clear, and exact desemption of the invention, such as will enable others skilled in the artto which it appertai-ns to make and use the same. D

This invention relates to improvements in combinedrunners and traction attachments forvehicles.

One object of the invention is to provide an' attachmentof this character comprising double runners connected by an integral web and having.- revolubly mounted therein sprockets with which is engaged a traction chain havingthereon a plurality. of shoes adapted -to engage the ground :or to dig into the snow( or ice whereby the chain is enabled toobtain a firm grip onthe surface over which the xvehicle is traveling.-

Another@ object is .to Yprovide. a runner and traction attachment adapted to be mounted onan axle spindle to take the place of the wheel thereon.

With-:these and other objects in view the invention consists of certain novel `features of construction, and the combination and arrangement of parts as will be more fully described yand claimed.

view through one side of the runner to more thereof; Fig. 14 is a side View of one of the tractionshoes; Fig. 15 is an end view there, of; and, Fig. 16 1s an inverted perspective View of the same.

Referring more particularly to the drawings, my improved runner comprises paralbars 1 spaced a suitable distance apart and connected at their inner edges by. 'an integral web l".v The runner bar comprises aA fiat ground engaging portion 2, curved or rounded ends 3 and 4, andinclined upper members 5 as shown. portions 2 of the runner and the top tions 5 where the same are the 'greatest distance apartlby pairs of verticali disposed sup. porting bars (Shaving on tli'eir inner edges lateral outwardly projecting bea1-ing,flangcs 7 which are curved outwardly between their ends to form a bearing 8 to receive the axle spindle and the runner attaching member whereby the runner is atta'chedto the axle as will be hereinafter more fully described.v The bars `6 are firmly braced and 'secured to the opposite ends of the runners by fronti and rear longitudinally disposed combined brace andbearing bars 9 and 10, the inner. ends of` which are riveted to the plates` 6 while the outerends thereof are riveted to the, flanges of the curvedlends ofthe runneri bars. The outer portion of the bar-sl) and 10 are disposed horizontally and 'have formed therein bearing openings 11 and 1.2 the purpose of which will be hereinafter described. The runner bars and the bearing bars 9 and 10 are braced by a series of.di'. agonally arranged brace bars 13 securedto the flanges of the upper and lowermembers as shown. The runner* bars are braced laterally by inclined brace bars 13 secured to the supporting bars 6 and to collars 13? arranged on the vehicle axle as shown. Rcvolubly engaged with flanges 8 of the inner Section of a bearing -boX and runner attaching sleeve 14 "which, when the lrunners are applied to a drivingaxle, is adapted axle spindle as shown in Fig. 4 of the draw; ings ,and which when l applied to stationaryV axlesis revolublymountedfen the spindle.

of the runner, bars and to saidbearing.barsV the hearing the runner is.

to be keyed. to the.

^ 4 mayhave applied thereto a braking mechanism and which when employed as shown in Fig. 5 has bolted or otherwise secured -thereto a driving sprocket with which the chain drive of the vehicle is engaged. When the runner is thus applied to the box 14 and the latter engaged with the spindle of the axle, a ball bearing 16 is arranged between the bearing flange 8 of the inner runner section and a ball bearin 17 is preferably arranged between the bearlng lia-nge 8 of the outer runner sectie-n, and the outer end of the spindle as shown. The axle spindle is provided with the usual tap or retaining nut 18 and the outer end of the bearing flange 8 of the outer runner section is preferably internally threaded and has secured therein a cap 19 which covers the tap 18 and outer end of the spindle. The portion of the sleeve or box between the sectlons of the runners is externally threaded and onto said threaded surface is screwed the main driving sprocket 20 of a traction mechanism hereinafter described, said sprocket being thus driven by the sleeve or box either through the axle as shown in Fig. 4 or by a chain drive as described in connection with Fig. 5. The sprocket a20 in. addition to its teeth for engaging the traction chain has annular series of teeth 21 arranged on opposite sides of its body and constituting driving gears connected by a pair of chains 22 with similar series of teeth 23 constituting pinions formed on the sides of a supplemental traction sprocket 24 revolubly mounted in the bearing apertures 12 of the brace and bearing bars 10 of the runners, said sprocket and its pinions 24 when thus arranged being adapted to work in the rear curved or rounded ends of the runners as shown. The driving gears 21 and driven pinions 23 are smaller than their respective sprockets, with the result that the chain or other connection between the gears and pinions are at their lower sides elevated above the first-engaging stretch of the traction chain so that dirt in the latter is not communicated to the former.

Revolubly mounted in the bearings 11 of the bearing and bracing bars 9 and in the opposite ends 3 of the runners is an idle sprocket 25 with which and with the main sprocket l20 and supplemental sprocket 24 is engaged a traction sprocket chain 26, said chain being adapted to travel in the space between the channel bars 1 of the runners and on the web 1a. It will be noted that where the sprockets are located the web, 1a

which connects the channel bars is cut out to form passages suiiiciently long to permit the teeth of said sprocket to project through the web and between the channels to engage the links of the sprocket chain 26. At suitable positions and preferabl at the ends of the passages in the webs 'or the sprockets 24 and 25 the channel iron runner bars are rigidly braced by channel iron brace bars 1b which are riveted or otherwise rigidly secured to the inner sides of the runner bars as shown. l

Secured to the traction chain 26 and preferably in alternate spaces between its links are shoes 28, each of which preferably comprises a body portion in the form of a flat block having its ends slightly reduced and rounded to form integral attaching lugs 29 which are adapted to be engaged by the adjoining links -ofv the chain and which are riveted or otherwise pivotally connected to said links, thus forming practically a part of the chain. The outer edges of the blocks extend beyond the outer edges of the chain and have formed thereon longitudinally disposed V-shaped ground engaging ribs 30 and said edges have also rigidly secured thereto or formed integral therewith transversely disposed ground engagin bars 31 having sharp or V-shaped outer e ges which together with the V-shaped ribs 30 bite into the ground or surface over which the runner is passing and thus insure a firm grip on said surface. The bars 31 extend beyond the opposite sides of the blocks to a considerable distance to provide an increased gri ping or traction engagement with t e ground. By providing both the longitudinal gripping ribs 30 and the transverse ripping bars 31 a resistance is offered in oth directions and the shoes` thus prevented from slipping either longitudinally or laterally.

The sprockets 24 and 25 are adjustably secured in their bearings in the bars 10 and 9 by adjusting screws 32 whereby the slack is taken up in the traction chain and in the drive chain 22 as will be readily understood. From the above description it will be seen that when power is applied to the shaft or hub of the main sprocket 20, its teeth engage the traction chain as indicated at the top of Fig. 1 and drive said chain in either direction around the runner; and its driving gears 21, connected by the chains 22 with the driving pinions 23, cause the supplemental sprocket 24 to rotate in the same direction as the main sprocket 20. The teeth of this supplemental sprocket engage the traction chain at a point where VJhe latter makes a sharp bend as seen, and therefore the links of this chain are in engagementl with said teeth for a distance almost half way around the sprocket. It follows that.

the rotation of the latter simultaneously assists in the movement of the traction chain over the runner in either direction, and yet by the construction described it is not necessary to apply the power to more than one point which by preference is the axle or ub of the main sprocket and the main driving gears.

Various changes in the formfproportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advanta es of the invention as claimed.

aving thus described my invention, what I claim 1s:

1. In a traction device of the class described, the combination with a runner comprising two spaced channeled members connected byan integral web so as to produce a lerigheral groovearound the runner, the we I avmg openings at points, and sprockets w ose teeth project through said openings; of a chain whose links travel in said groove and engage said teeth, and shoes each consisting of a body pivoted within the line of the chain and traveling within said groove, and transverse earth-engaging portions carried by the body and projecting laterally outward over the channel members ofthe runner.

2. In a traction device of the class described, the combination with a sleeve adapted to be mounted on an axle spindle, means for rotating said sleeve, a main sprocket fast on the latter, and a runner in which the sleeve is journaled; of a traction chain passing around the periphery of the runner and engaging the teeth of said sprocket, a supplemental sprocket journaled in the runner and its teeth also engaging said chain, and means for connecting the main and supplemental sprockets so that power from the former will be im arted to the latter, for the purpose set fort 1.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
