WALTER H. ANDERSON, OF NEW YORK, N. Y.

RUNNER ATTACHMENT FOR AUTOMOBILES.

SPECIFICATION forming part of Letters Patent` No. 756,556, dated April 5, 1904.

Application led August 13, 1903.

To all whom it mctyconcern:

Beit known that I, 1V ALTER H. ANDERSON, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Runner Attachment for Automobiles, of which the following is a full, clear, and exact description.` The purpose of my invention is to provide a form of runner adapted to be fitted to the rear axle as a substitute for wheels and to provide the runners with propelling mechanism and driving devices for said mechanism, together with means for operating the driving devices from the rear or driving axle of the automobile, the propelling mechanism including an endless chain of lugs or spurs adapted to extend through slots in the shoes of the runners and enter the snow or piercethe ice to such an extent as to have sufficient grip when the propelling-chain is operated to force the machine forward, the improved runners being used in connection with any desired style of forward runners.

A further purpose of the invention is to provide runners of the character described which will be strong, light, and readily applied and removed and to provide supporting devices for such runners that will enable them to adjust themselves to the irregularities of the surfaces traveled over and also to provide simple v and conveniently-operated means for adjusting the carriers for the propelling-chain of lugs or spurs to take up the slack of the chains or to raise or lower the lower stretches of the chains, as may be desired.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of one of the irnproved runners and a portion of the body of a vehicle. Fig. 2 is a longitudinal vertical section through a portion of the runner shown located, preferably made of steel, and the sa in Fig. 1.` Fig. 3 is a central transverselsecf serai No. 169,346. (No model.)

tion through the runner and a side elevation of a portion of the driving-axle and its bearing and a hanger for adjustably connectingJ the runner with the axle-bar; and Fig. 4 is a ection taken practically on the line 4 4 of A represents one of the runners,two of which are employed at the rear of the vehicle, a portion of the body B whereof is shown in Figs. 1 and 2. Each runner is of the same construction, and consists of` a body, east, forged, or otherwise produced, comprisingparallel side members 10, a front member 11, curved rearwardly at the bottom, and a rear member 12, more or less curved-downward and forward at-itsv bottom. p

The top of the body frame or casing of a runner is open from front to rear, and in the bottom of the said body frame or casing a longitudinal opening 13 is made, extending from a point near the front to a point near the back, as is indicated by dotted lines in Fig. 1. 1^ the bottom portion of a runner a shoe B' shoe is provided with a longitudinal opening.,

14, registering with the bottom opening 13 in' the body frame or casing of the runner, and the forward end 16 of the shoe is upwardly curved andts close to the forward end of the runner'a/tits exterior, extending to a point practically between the center and upper edge of the body frame or casing, as is shown in Figs.` 1 and 2, while the rear or heel end 15of the shoe is upwardly and rearwardly curved and is fitted to the corresponding lower portion of the said body frame or casing, as is illustrated in Fig. 1.

Theforward portion of the shoe is secured to the said body frame or casing of the runner by means of bolts 17 or their equivalents, as is illustrated by dotted lines in Fig. 1, and other bolts 18 are located intermediate of the' ends of the shoe and at the heel portion of the slice, extending upward into the side portions of the body frame or casing, the said side portions 1() of the body frame orcasing having openings 19 therein to receive the upper ends of the bolts 18, which 'upperendsare provided withsuitable nuts, asis shownyin Figs. l and 3,

thus rendering it very convenient to remove a shoe when it has become unduly worn and replace it by another.

rlhe outer side member 10 of the casing or body frame of each runner is provided oen-Y trally between its ends with an interiorly-located tubular boss 20, as is shown in Fig. 3,

and the chamber of the boss is closed at the outside by a suitable plug 2l, so that access to the chamber or bore of the boss may be conveniently secured, and at the inner face of the boss 2O a ball-race 22 is located, which ball-race is adapted to receive a conical section 26, formed on the hub of a pinion 24, which pinion 24, as is shown in Fig. 3, is secured upon an outer end of the rear or driving axle 25 of the vehicle. The said rear axle 25 is adapted to turn in a tubular bearing 27, at tached to the body of the vehicle or its running-gear by suitable braces 28. The outer ends of the tubular bearings 27 extend into the hub portions of the pinions24, one of which pinions, it will be understood, is employed in connection with each runner. The said hub portions of the pinions 24 have bearing-rollers 24 therein to engage with the said tubular bearing, as is indicated in Fig. 3.

Each runner is held in position by means of I a bracket-arm 29, and these bracket-arms are attached to the central portion of the outer faces of the inner side members of the runners. Each bracket-arm 29 terminates in an upwardly-extending jaw 30 of segmental formation, as is shown in Fig. 4, and each jaw 30 is provided in its inner edge with a groove 31, as is indicated in Fig. 4. One upper member of the jaw 30 is provided with a hinged section 32, having a downwardly-extending integral lug 32a at its bottom portion and below the pivot 33 for the said hinged section, as is indicated in Figs. 3 and 4. The said upper hinged section or member 32 of the jaw 30 is held in closed position (shown by dotted lines in Fig. 4) by means of a bolt 34, passed through the stationary portion of the jaw 30, entering a recess in the lug 32 of the said drop or pivoted member or section 32 of the jaw.,

The jaw 30 is adapted to hold a plate 35, which has a peripheral rib formed thereon, adapted to turn loosely in the groove 31 in the inner edge of the jaw 30. The said plate 35 has apertured lugs 36 extending from its ends, as is shown by Figs. 3 and 4, and is provided with a substantially central opening of suilicient size to receive the bearing 27 of the driving-axle 25, and the said plate 35 is further provided at its upper central portion with a vertical opening communicating with the central opening just mentioned, the vertical openings in the plate 35 being adapted to receive a clamping-block 37, having serrations 38 at its bottom edge for engagement with the upper surface of the tubular bearing 27 for the driving-axle25, the under or lower serrated face of the said clamping-block being made to conform to the upper surface of the said tubular bearing 27. This clamping-block 37 is held firmly in engagement with the tubular bearing 27 for the driving-axle 25 by means of yokes 39, the ends of which are threaded and passed through apertures in the aforesaid lugs 36 on the plate 35. The said 1 yokes are held in clamping position' by means of suitable nuts 40 at their lower threaded ends bearing against the under faces of the lugs 36, as is shown in both Figs. 3 and 4. Under this construction Of support for the said runners it is obvious that therunners while suitably supported by the driving-axle and bearings therefor are capable of vertical movement at their forward and end portions, so as to permit the said runners to pass over an undulating surface without undue interference.

Slots 41 are produced in the upper edges of the side members of the frame or casing of the runners, the said slots being one at each side of the center of a runner, and the slots are oppositely and downwardly curved, as is illustrated in Fig. l.

At the margin of each slot 41 on the outer faces of the runner bodies or casings offset and eXteriorly toothed or serrated surfaces or bosses 42 are formed, as is shown in Fig. 1, and through transversely-opposing slots 4l in each runner a spindle 43 is passed, provided ,at each outer end with a washer 44, toothed or serrated to engage the serrations of the bosses 42, above referred to. These washers are held lirmly in engagement with the bosses 42 by suitable nuts 45 on the outer ends of the spindles 43.

A sprocket-wheel 46 is held to turn loosely on each spindle 43 within the frame or casing of the runner carrying the spindle, and each sprocketwheel. 46 has preferably attached thereto a gear-wheel 47, the sprocket-wheels being of equal size and the gear-wheels 47 larger, but of the same size one with the other. The gear-wheels in each runner mesh with the teeth of the pinion 24, carried by the end of the driving-axle 25 entering the runner, so that as the aXle 25 is revolved the gears 47 are set in motion, and consequently the sprocketewheels 46.

The sprocket-wheels in each runner carry an endless chain C, and each chain C consists of a series of lugs or spurs 48,` connected by links 49. The said spurs or lugs 48 are preferably so formed that one edge is segmental and the other edge is straight, and the said edges are so disposed that the lugs or spurs on the lower stretch of the chain C have their straight edges facing rearward and their seg- 'mental edges facing forward.

the runners and the longitudinal openings 14 in the shoes attached to the runners, and the lower stretches of the propelling-chains C are held parallel with the bottom of the shoes by engagement with friction-rollers 50, provided, preferably, with end flanges, as is shownv in Figs. 2 and 3, the trunnions of the said rollers being mounted Vin boxes 5l, suitably located in the inner faces of the casings of the runners, as is shown in Fig. 3, and held in place bythe shoes B of the runners when the shoes are applied.

It will be observed that by adjusting the spindles 43 upward or downward the propelling-chains may be tightened or loosened, as required. In order to prevent the runners from having undue lateral movement, couplings 52 are pivotally attached to their forward ends and are likewise pivotally attached, preferably, to the reach 53 of the vehicle, although. the said couplings may be attached to any other convenient portion of the running-gear or when desirable to the bottom of the body B of the vehicle.

The runners A at the rear of the vehicle may be used in connection with any suitable form of forward runners, and as the propelling-chains C are set in motion the lower spurs or lugs 48 will enter the snow or penetrate the ice over which the vehicle is being pro-` pelled. As the chains at their lower stretches move in direction of the rear of the vehicle the said chains in their rotation around the sprocket-wheels 46 serve to propel the vehicle forward with more or less speed, according to the speed at which the driving-axle is rotated.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
