NTTnD STATES FRANCIS T. T. STANIER, OF C-HILLIVACK, CANADA.

SUPPLEMENTAL SEAT FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 621,722, dated March 21, 1899.

* Application filed September 19,1898. Serial No. 691,361. (No model.)

T0 all whom t may concern:

Be it known that I, FRANCIS T. T. STANIER, a citizen of the Dominion of Canada, residing at Chilliwack, in the Province of British Columbia, Canada, have invented a new and useful Supplemental Seat for Bicycles, of which the following is a specification.

My invention relates to improvements in supplemental seats for bicycles; and it consists of a horizontal support-bar ,passing through the rear frame of the bicycle, to which it is attached, with the inner end resting against the rear part of the frame, into which the saddle-post is introduced, and resting on the cross-tie of the saidframe. The backward end of the bar iswidened to support the seat, and this is supported byafleXible stay passed over the saddle-post.

The object of my invention is to provide a seat for a child that is very simple and cheap and that may be attached to any of the standard patterns of bicycle frames with little trouble and delay and also that may be adj usted to place the seat at the desired pitch for the comfort of the rider. I attain this object by the mechanism or the apparatus illustrated in the accompanying drawings, in which- Figure 1 shows the position of my invention when in use. Fig. 2 is a plan of the seat detached. Fig. 3 isan inverted detail plan showing the means for fastening the opposite ends of the tension-wire. Fig. 4 shows a side elevation of the same and Fig. 5 is a cross-section of the clamping-plate, taken on the line 1 1 in Fig. 2.

Similar letters and nu'merals refer to similar parts throughout the several views.

The longitudinal bar 10 is preferably made of wood, and it is formed to pass between the forks of the rear part of the frame, as a, and rest on the cross-tie b, which forms afulcrum, and its inner end is provided with a flute 10a, which snugly fits and rests against the frame c. The projecting end of the bar 10 is widened and formed to support aseat 11. This, however, may be modified and made to suit the requirements of the demand. Secured .to and beneath the bar 10, approximately at its point of enlargement for the seat, is a wedgeshaped plate 12, and lying against this plate 12 is a similar one, 13, the same being held drawn from between the

plates

12 and 13 by the weight of the rider, Iprovide their facing surfaces with corrugations 16, these flutes being placed at right angles to the ends of the wires 15,so that as the plates are forced toward each other by the bolt 14 the said ends of the wire will be securely gripped by the ribs of the corrugationsA As the rear forks of the frames in bicycles are not all placed the same distance apart itI is obvious that the bar 10 in some instances will not fit and lie close to such forks. Therei fore to provide against any lateral movement of the bar I provide a slidable plate 17. (See Figs. 2 and 5.) The said plate 17 is secured to the bar 10 by a bolt 18 passing through a longitudinal slot therein and through a slot 17fL in the said plate. When the bar 10 is placed between the forks o, the plate 17 is pressed tight against the same and secured with its wide end on the inner side of the forks, so that the bar 10 cannot work backward.

To prevent the edges of the plate 17 from making contact with and abrading the forks and from having lateral movement, the edges are turned down, as at 17h, and thus present iiatsurfaces to the said forks instead of narrow edges.

From the foregoing it'is shown that my seat may be universally adopted, and it may be attached and detached to and from abicycle in a very short space of time, it being simply necessary to drop the loop over the saddle and let it rest on the post d and adjust the plate 17 to prevent the bar 10 from having any lateral movement.

Having now described my invention, what I claim, and desire to secure by Letters Pat ent, is;

roo

l. Asupplenlental seat for a bicycle,oo1npris ing a bar l0 arranged to lie on the cross-tie I) of the frame and with its fluted end resting against the frame c, and an adjustable tension- Support l5 secured beneath the seat on the projecting end of the said bar and lying over the saddle-post d, as specified.

2. A bar l0 having a fluted end to lie against the upward rear proj ectin g frame cof abicycle, the said bar to pass between the rear frames of same, a wedge-shaped clamping-plate 17 on the upper side of said bar, and a bolt passing through a longitudinal slot in the bar and a slot in the said plate7 whereby the plate may be secured to connect with the opposite forks a of the frame, and means forsupporting the projecting end of the bar on which is arranged a seat, as specied.
