CHILDS SULKY.
Specification of Letters atent.
Patented Feb. 18,1913.
' Application filed March 22, 1912. Serial No. 685,494.
- improvements in collapsible sulkies for children of the type shown in my application No. 654,3?5, filed October 12, 1911, and is designed primarily to produce a sulky that can be drawn ofi of the curbsitone', or some similar offset, without a serious jar. To this end, I employ small supplemental-wheels located to the rear of, and preferably with their axles in the same horizontal line as the axles of, the two main wheels.
Another feature is designed to provide an improved locking mechanism t0 hold the parts in their extended'positions.
To illustrate my invention; I annex hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of Which,
Figure l is a sideelevation with the adjacent wheel and fender removed, as if the same were in section on the line A A. of Fig. 2; Fig. 2 is atop plan view; Fig. 3 is an enlarged detail in section on the line E-B oi Fig.1; and Fig. 4: is an enlarged I To illiistrate my invention, I have shown a collapsible sullry of substantially the same construction that shown in my aforesaid applicat on No. 4,375, where the horizontal. "ea ame 10 has the handle 19 conu etc, so that it can be held rigid with name in. use, or folded back upon it for collapsihg the sullry. The back-rest frame 30 is pivoted tnthe rear of the seatthe frame, and the J-shaped vertical arm-frame pivoted to the seat-frame at 43' coiiperates with lugs 58 secured to and projecting inward from the under side of the horizontal braces-56 of the wheel frames 51, which are pivoted to the lugs 52 extending down from the sides of the seatframe 10, so that the Wheel frames can he -collapsed and.
folded up underneath the seatframe'by-the closing movement of the back-rest frame 30 and the arm-frame 42,: these frames being.
connected by the horizontal links or arm rests 45. The stop-frame pivoted to seat frame I l the horizontal seat-fraine at 32, and the foot-rest frame 37 is pivotally connected at its forward end to the stop-frame or standard 34 and at its rear end to the bottom .bar- 40 of. the U-shaped arm-frame, so'th'at' a lazy-tong construction is formed which per mits of the cart being collapsed. In the ord-inary construction of these sulk-ies, when it is necessary to run off of a curb,it is practi cally impossible to prevent a jar without picking up the sulky bodily and lifting it down. To remedy this difficulty, I provide an extension 55 having journaled. on the rear end thereof the small Wheel ,62, and
preferably I provide apair of these exten-, sions 55 and WhBBlS'GQ, and secure one on v the rear side of each of the Wheel-frames 51.
This extension may be constructed of metal shape and location as to bring the hubs of the wheels 62 in the same horizontal plane as the hubs of the main Wheels 48 when the stands' horizontally. These wheels- 62 serve to prevent the jar that otherwise occurs in passing over a curb, as
-when the main Wheels pass off of the curb and the body of the sulky is held level, the Wheels 62 catch on the curb as the main wheels leave the curb, and prevent the jar which-would otherwise occur. The .sulky can be run upon a curb by backing up to it and tilting the handle down until the standard 34 strokes the ground, in which position the auxiliary wheels 62 will be raised high enough so that they will extend .over the top of th'e ourb, after which the sulky can be lifted higher at its front end by the handle and the main wheels 48 rolled onto the curb Without any substantial jar.
In copnection with my invention I may employ a novel mounting for the seat proper'll, and this seat is preferably con structed offa sheet of metal rigidly secured at the forward side to the arm-frame 42, preferably by being riveted to a cross-v bar 63, which has turned-downends riveted to the vertical bars of thearm-frame 42.
,The rear corners of the seat, which rear is have riveted to the under side of the bar the curved springs 65, the other ends of which are riveted to theend bar 14 of the horizontal seat-frame-IO, and are preferably strengthened by the short auxiliary pieces 66,--betweenwhich and the bar 14" the ends of the springs 65 are riveted. By the construction shown; it will be seen that I have produced a very light seat that is springsupported at its-rear end, so that it can yield under the weight of the occupant sulficiently to take up some of the jars met with in the use of the sulky.
The last feature which may be used with.
my invention consists of the novel locking mechanism employed to hold the parts in their extended position. As best shown in Fig. 3, the bottom bars 50 of the wheel frames have riveted on the forward corners thereof the catches 67, which have the verti' cal blade portions terminating in the curved ends 68, which are adapted to be struck by the lower partsof the verticalbars of the arn'i-rest frame 42 as the parts are swung to their extended position and to spring the clips until the curved ends 68 are passed,
. While I have shown and described my invention as embodied in the form which I at present consider best ada ted to carry out its purposes, it will be un crstood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claim except as may be necessitated by the state of the prior art.
\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is:
In a. collapsible vehicle, the combination with a horizontal scat frame, of wheel frames pivoted to the sides thereof and hav- 111g rearward extensions, the rear ends oi which extend beyond the seat frame, means for moving said wheel frames into and out of and securin them in operative position, a main wheel or each of said wheel frames journaled thereon below the seat frai e, and
small wheel for the purpose de cribed journaled on the rear end of each of the extensions.
In witness whereof, I have hereunto 'set my hand and affixed my seal this 20th day of March, A. D. 1912' RHINEIIARDT H. BROWN- W'itncsses JOHN HowAn'n MoELnor, MILDRED ELSNER.
