MAGDALENA DIENER AND CHARLES FREDOLIN URBAN OF MILWAUKEE WISCONSIN.
Specification of Ietters Patent.. Patented May 14 1912. Application filed November 14 1810. Serial No.
To all'whomit may camera:
Be it known that we MAenaLFNA DIENER a citizen of the. United States and CIIASLES FREDOLIN URBAN a citizen of the' Republic
5 of. Switzerland both residents of Sycamore street Milwaukee in the county of Milwaukee anal the State of Wisconsin have invented a new and useful Sleigh of which the following is a specification.
10 This invention has for Its object to 'provide a sleigh or coasting device comprising a single runner having a comparatively short bearing surface with curved ends which facilitate the turning of the runner
15 beneath the rider for steering' purposes and for assuring. an easy landing after making' leaps when coasting down irregular surfaces.
Another object of this invention is to
20 provide such a coasting device with a foot rest which will assist the rider in maintaining equilibrium.
Another object of this invention is to provide such a coasting device of strong and
25 durable construction while being inexpensive to construct and of light weight and easily carried from place to place.
With the above and other objects in view the invention consists in the sleigh as here30 in claimed and all equivalents.
Referring to the accompanying drawings in which like characters of reference indicate the same parts in the different views : Figure 1 is a side elevationof a coasting
35 device constructed in accordance with thin invention and. illustrating the preferred form thereof Fig. 2 is a plan view thereof Fig. 3 is a front elevation thereof with the runner in section and showing by dotted
40 lines the movements of the swinging foot rest Fig. 4 is a side 'elevation of a modified form of . the invention adapted for use by ladies and Fig. 5 is a detail plan view of the swinging foot' rest thereof.
45 In these drawings 1' indicates the runner
frame which is preferably of light. Tiron
as shown and is bent to a substantially oval
shape with its two ends brought together
and welded 9r riveted or otherwise firmly
So united and 2 Indicates a strengthening brace
rod extending transversely across the frame
with its ends riveted to the flanges of the
frame to prevent the possibility of the
frame collapsing on striking the ground
55 after' a long leap. Some distance in front
of the brace the flange of the runner frame is provided with an opening into which is engaged the hooked upper end of a Tshaped foot rest 3 which is thus suspended and free to swing from side to side as shown 60 by dotted lines in Fig. 3. Another foot rest 4 is adjustably and detachably clamped sta. the flange of the runner frame and is employed by the more experienced riders for assisting in swinging the frame beneath the 65 rider for steering.
A seat 5 is adjustably and removably mounted on the runner frame by having clips 6 fitting around the flange of the frame and field to the seat by winged nuts 70 'T and while the nuts are loose the seat may be moved along the runner frame to position it properly according to the' angularity of the descent to be made. This seat is desirably padded at its middle portion and is 75 provided with openings 13 at the ends to form hand holds which are grasped by the rider.
In use the rider sits upon the seat and firmly grasps the hand holds at each side 80 with his weight resting upon the device and with his feet on the ground to hold him upright he starts the descent by taking a few steps and then as soon as he has acquired enough momentum to enable him to main 85 tain equilibrium he places both feet upon one of'the foot rests and continues the descent. ' The device is kept beneath the rider by his pulling upon one or the other of the hand holds so as to tilt it one way or the 90 other as required and when it is desired to turn to avoid obstruction or for steering' a desired course the rider leans to one side or the other so as to throw his weight out
of equilibrium and at the same time swings 95 the runner beneath him on a vertical axis by ' pushing forward with one hand and pulling rearward with the other.
While running on a smooth surface either horizontal or inclined the runner rides on a flat surface which is approximately onethird of its entire length. In order that the runner may easily pass up and down irregularities in its course its bearingg surface iscurved at a varying pitch which has been found in practice to be most desirable for leaping as being capable of landing successfully whatever point of the bearing surface the runner is the first to strike. These leaps are made of great length
the rider acquiring a high speed in a descent . and then quickly turning up a short incline so that his momentum will carry him many yards. It is obvious that after such a
5 leap the runner may again land on an incline or a decline or a level surface and it is of utmost importance that wherever the runner may first strike it will present' a smooth bearing surface capable of support
10 ing the rider. It is for this reason that the curvature at the front end of the runner occupies nearly half the length of the device while the curvature at the rear is of sufficient extent to right the position of the
15 device after a leap which is ended upon a further decline. The short comparatively straight portion of the bearing surface of the runner is of further advantage in that it is positioned directly beneath the seat and
20 offers much less resistance to the turning movement thereof for steering purposes than would be true if it were longer.
That form of the invention shown m Figs 4 and 5 is designed for lathes' use the oval
2.5 shape of the frame 1 being departed from while the shape of the bearing portion of the runner remains the same. In fact the frame 8 "beginning at the front end follows the same outline as the frame 1 until after
30 the seat is passed when it turns abruptly downwardly and meets the runner just in advance of the straight portion thereof. Thus the downwardly bent portion takes the place of the brace 2 of the other construe
35 tion and leaves the frame open in front of the seat to accommodate the skirts of the rider. As this portion of the frame is open the footrest cannot be suspended as before
and consequently it takes the form of a
bracket 9 pivotally mounted on hooks 10 on
this downwardly bent portion of the frame
the bracket carrying a cross piece 11 at its
end held by a clamping screw 12. This form
of the : invention is operated in the same
manner as the. other. When desired the bracket footrest (9) may be provided for that form of the invention shown in Figs. 1 2 and 3 the bracket being pivotally attached to the brace (2) in the same manner
as it is attached to the downwardly bent 50 portion of the frame in Fig. 4.
The swinging foot rests are more particularly used by beginners to enable them to more readily throw their weight from one side to the other to maintain equilibrium 55 but with experienced riders this becomes an acquired accomplishment and then the fixed or adjustable foot rest 4 is preferred as being more effective for assisting in bracing the body when . making long leaps. The 60 seat and foot rests are made detachable so as to be capable of being packed within the frame for shipment or for carrying the device from place to place.
What we claim as new and desire to se 65 cure by Letters Patent is:
1. A coasting device comprising a single runner frame of Tiron having an oval shape with comparatively straight parallel topand bottom portions the bottom portion 70 forming a straight bearing surface of approximately onethird the length of the frame with a rounded front end and the top portion forming a seat support a transversely extending seat adjustably mounted 75 on the straight top portion of the frame and clamped thereto said top . portion of the frame also affording a support for a swinging foot rest in front of the seat support a swinging foot rest suspended therefrom 80 and the rounded front of the bottom portion of the frame affording a support for a foot rest and a foot 'rest adjustably mounted thereon.
2. A coasting device comprising a frame 85 of Tiron having an oval shape with approximately parallel top and bottom portions a seat adjustably clamped to the top portion of the frame a brace connecting the tap and bottom portions of the frame be 90 neath the seat and a bracket foot rest pivotally mounted on the brace.
