SADDLE-SUPPORTING DEVICE FOR CYCLES.
SPECIFIGATIONforming part of Letters Patent No. 658,909, dated October 2, 1900. Application filed December 2, 1899. Serial No. 738,955. (No model.)
To (ZZZ whom it may concern:
Be it-known that I, DOSSABHOI SHAPoYE FRASER, a subject of Queen Victoria,Empress of India, and a resident of Bombay, India, have invented new and useful Improvements in Saddle-Supporting Devices for Cycles and the Like, (for which I have filed an application for British Letters Patent No. 21,391, dated October 26, 1899,) of which the following is a specification.
This invention relates to an improved device for supporting in a yielding manner the seat-pillars of cycles and like vehicles; and it consists of a self-contained device applicable to existing cycles in which the seat-pillar is supported in an unyielding manner by being nipped by a bolt in the seat-bracket at the top of the diagonal frame-tube without any alteration of the cycle itself, whereby such disadvantages as appertain to such existing devices of the kind which require the cycle to be altered or adapted to them are avoided, the improved device thus permitting of the advantages of a yielding seat pillar being more generally obtained.
On the accompanying drawings, Figure 1 represents the improved device in sectional elevation, showing the same applied to an ordinary cycle-frame shown in dotted outline. Fig. 2 represents a sectional plan on 2 2, Fig. 1, without representing the cycle-frame. Fig. 3 represents a like view on 3 3, Fig. 1; and Fig. 4 represents a like view on 4 4, Fig. 1.
In carrying out the invention I arrange within the upper end of an incasing tube 1 a guide-tube 2, locating the same in the tube 1 in a separable manner by screws 3, and I arrange within the tube 2 the stem or downward member 4 of the seat-pillar, locating'the same in the tube in a separable manner and also in such a manner as to allow of limited endwise or falling and rising movements of.
the seat-pillar and as to prevent rotative movements thereof by screws 5, working in slots 6, made in the tube 2. I also arrange within the lower end of the tube 1 an internally-screw-threaded collar 7, locating the same in the tube in a separable manner by screws 8, and within and engaging with such collar I arrange in an adjustable manner an eXternally-screw-threaded elongated tubular bolt 9, having a flange 10 at its top end and being nicked at 11 at both its top and bottom ends to facilitate its placement and its adjustment in the collar 7 by means of a screwdriver or the like.
Between the bottom of the seat-pillar stem and the top of the adjustable bolt 9 I arrange -a helical spring 12, preferably locating the holes 14 in the tube 1.
The device thus forms a self-contained cycle auxiliary as an entity applicable to and removable from the diagonal frame-tube 15 of a cycle without any alteration of the latter and is located within the ordinary seatbracket 16 by the ordinary nut and bolt 17 exactly in the manner in which the ordinary seat-pillar is located in a rigid or unyielding manner, but with the advantage of obtaining a yielding seat-pillar. The device also allows of any desired adjustment of the height of the seat to suit different riders without requiring any alteration in the adjustment or relation of its parts and simply by slackening and refastening the nut 17 and raising or lowering the device as required.
What I claim as my invention, and desire to secure by Letters Patent, is-
A device for supporting in a yielding manner the seat-pillars of cycles and the like, consisting of the combination with an incasing tube, of a guide-tube therein having longitudinal slots, a seat-pillar fitting in said guidetube and carrying studs engaging with said slots, a nut secured in the incasing tube below the ends of the guide-tube and seat-pillar, a screw meshing with said nut, flanged caps on said screw and under the ends of the guide-tube and pillar, and a helical spring between said caps.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses;
