RUNNER ATTACHMENT FOR TRACK-SULKIES.

set and State of Maine, have invented certainnew and useful Improvements in Runner Attachments for Track-Sulkies; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same.

This invention relates to improvements in runner attachments for track sulkies of that type wherein the ordinary track wheels are held to thesulky through the medium of a displaceable bolt spanning the space hetween theforked wheel carryingmembers.

The main and primary object of the present invention is the pro-vision of a runner attachment of the character described, by which the modern type of track sulkies may be readily converted from a wheeled vehicle into a runner supportedvehicle, there by adapting the same forice racing as well as for racing under the ordinary conditions.

A further object of the present invention is the provision of a runner attachment the construction of which is such that therunners are preserved in parallelism with each other so as to insure proper trackmg of the sulkyandto include with the construction of the attachment simple andeflicient means for rigidly supporting the same upon the sulky.

While the invention is primarily intended a for use with the light-frame sulky of the modern type it is also capable ofuse with other types of road sulkies and carts, so that its use is not limited to the modern track Q sulkywhich is now commonly used.

I-Iaving these general objects in view the invention conslsts substantially in the novel construction, comb natlon and arrangement of parts hereinafterfully described, illus-. trated. in the accompanying drawing, and;

pointed out in the appended claim.

with the runner applied thereto. I

Referring in detail to the accompanying drawings, the numeral 10 designates the frame of a track sulky. Asjthese modern sulkies are commonly constructed they include depending forked members llprovided with forwardly extending braces 12, the rear ends of the braces being connected to the lower ends of the forked members 11, while the forward ends of said braces "are connected to theshafts 13 of the sulky, The road wheels are held within the forked members 11 by means of bolts 14;, and it'is the purpose of the presentinvention to utilize these bolts as the securing means for connecting the runner attachments to the sulky frame. r

As clearly illustrated in Figs.1 and 2,,the

runner attachment constituting the present 75 invention comprises a shoe 1 5, the forward at a pointzsubstan'tially midway its ends, is a substantially U-shaped standard 16, the

lower end of which is secured as by rivet ingto theshoe 15. j The upper ends of the standard 16 being separated, a space is provided thereat and fitting within the upper ends of the standard, 16 is a supporting plate 17, the sides of which are provided with upwardly extending parallel. ears 18 which are perforated and designed to receive the bolt 14:- At the under side of the supwhich are inclined downwardly to the shoe 15 and are preferablyriveted thereto." It will thus beseen that the supportingplate 17 is sustained bythe middle portion of the brace 19' and lateral movement of said supsides of the vertical standard 16.

ture, an inverted U-shaped strap 20 is ar ranged in the lower end of the standard 16, the extremities ofsaid strap being also secured to the shoe 15 at the front and rear sides of the standard-16. a

Seated uponthe ears 18 is a securing clip 21 of inverted .U-shapegthe extremitiesof bolt 14, and connected to said clip 21 is a brace 22, which extends upwardly within the forwardly extending brace .12 of the sulky 6 frame, the upper end of the brace 22 being 110 porting, plate is likewise prevented'by the runner attachment at the opposite side of the sulky. In doing this, however, the shoe 15 is free to rotate upon the bolt 14: as its axis and thus to rise and fall with the inequalities of the road bed but without disturbing the parallel relation previously re-' ferred to.

As a further means of guiding the for- Ward end of the shoe 15 a strap 2% is employed, said strap being connected to the forward end of the shoe 15 and also to the sulky frame as at 25.

lVhen it is desired to equip a sulky with the herein described runner attachment the ordinary road wheels are removed by properly displacing the bolt 14 at each side of the sulky. hen this has been effected the hereindescribed runner is introduced between the lower end of the forked members 11 of the sulky frame, the clip 21 being positioned so that its perforated portions will register with the perforated ears 18 of the supporting plate 17. The bolt 14: is now passed through the perforated ears 18, the clip 21 and the forked members 11 of the frame and the upper end of the brace 22 is attached by its clip 23 to thebrace 12 of said frame. The strap 24 when employed is also attached in the manner as previously described.

With the parts adjusted as stated it will be seen that the runner is free to oscillate upon the bolt 14% but by means of the brace 22 it is held rigid against lateral movement so that both runners are always preserved in proper parallel lines and under these conditions it will be understood that the sulky may be used for ice racing without liability of derangement of the runners.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:

A runner attachment for sulky frames comprising a shoe, a substantially U-shaped standard rising therefrom, a supporting plate fitted between the sides of said standard and provided with parallel perforated ears, a brace arranged at the under side of said supporting plate and having its ends connected to said shoe for supporting said plate in relation to said shoe, a bolt passing through the sides of the U-shaped standard, a clip 21 connected to said bolt and a second brace 22 connected at its lower extremity to said clip 21 and removably attached to the sulky frame to furnish additional rigidity to said frame and preserve the parallelism of the runners.

In testimony whereof I affix my signature in presence of two witnesses.
