SEAT-POST AND CLAMP.-
SPECIFICATION forming part of Letters Patent No. 670,414, dated March 19, 1901.
Application filed August i, 1900.- Serial No. 25,960. (No model.)
,Zo aZZ whom it may concern.- Be it known that we, JOHN ENGLAND, a resident of London township, and MOSES HUTCH INSON, a resident of the cityof London, in the coun ty of Middlesex, in the Province of Ontario, Canada, subjects of the Queen of Great Britain, have invented a certain new and useof which the follow- .in g specification, taken in connection with the accompanying drawings, forms a full, clear, and exact description. p
This invention relates to the construction of a device for firmly clamping and holding desired elevation in a the seat-post at any seat-post mast; and it consists in so constructing the seat-post and providing it with a taperedsleeve or clamp formed in sections whereby the seat-post may be adjusted at any desired elevation in the seat-post mast and by which said seat-post when properly adj usted is tion and by which without the use of tools the seat-post may be readily and easily removed from or adj usted and clamped at any desired elevation in the seat-post mast, all of which will be hereinafter first fully set forth and and then pointed outin the claims. Reference is had to the accompanying drawings, wherein- 1 a Figure 1 isa side elevation of the seat-post,
tapered sleeve or clam p, and the adjaceht portion of a bicycle-frame embodying ourjinvention. In this view a portion of the seat-post mast is shown in section and theadjacent parts of the bicyclerframe in dotted lines. Fig. 2 is another view of same, showing a central sectional view ofa portion of the seatpos, and tapered sleeve or clamp. Fig. 3 is a detail side elevation of the seat-post, partly in section, and a central sectional view of the tapered sleeve or clamp, the seat-postand clamp being slightly separated in order to more clearly illustrate the construction of these parts. Fig. 4 is a detail, central sectional view of the tapered sleeve or clamp; and Fig. 5 is a plan view of same, showing the sections of which the clamp is composed separated.
In the accompanying drawings the numeral 1 designates the seat-post mast, 2 the :op bar, and 3 the backstays of a bicyclefirmly clamped and held .at said eleva-- frame, the upper internal face .of the seatpost mast -1 being tapered at a.
4 designates the seat-post, tothe upperv end of which the seat or saddle is secured.
5 5 designate two rows of shoulders formed in the seat-post 4, and these shoulders 5 are preferably formed in said seat-post by swaging or pressing inward a portion of the metal of which the seat-post is com posed, thus leaving the inwardly-projecting tongues 6, as
shown particularly-in Fig. 3.
7 designates a tapered sleeve or clamp preferably each of which is provided with a stop 8, preferably formed by swaying or pressing inward a portion of the metal ofwhich the'sectionsof said clamp are composed, thus providing a. tongue 9, the end ofwhich forms the stop 8, as shown particularly in Figs. 3 and 4, and
formed in two segmental sections b 0,.
the upper internal face a of'the seat-post mast 1 is formed tapering to correspond with the taper on the sleeve or clamp 7, in order that said sleeve may bear on a large area of the adjacent face of the seat-post mast, andthus provide a wide and strong support for the seat-post.
By engaging the two opposite stops '8 of the tapered sleeve or clamp 7 with two opposite shoulders 5 in the seat-post 4 and then insorting said tapered sleeve or clamp 7 and seat-post 4 in the seat-post mast 1 until they fit snug in theupper tapered end thereof the seat-post 4, to which the saddle orseat is attached, will be firmly clamped and secured in the seat-post mast. Again, by removing the seat-post4 and tapered sleeve or clamp 7 from the seat-post mast 1 and adjusting the sections of the clamp 7 so that the stops 8 will engage with higher or lower shoulders 5 in the. seat-post the latter will be at a corresponding higher or lower elevation, according to the direction the tapered sleeve or clamp is adjusted on the seat-post. By adjusting said tapered sleeve or clamp 7 upward on the seat-post the seat-post and saddle or seat will beat a lower elevation, and byadjusting said tapered sleeve or clamp 7 downward on the seat-post the latter, as well as the saddle or seat secured thereto, will be ata higher elevation.
The frictional contact of the tapered sleeve IOO or clamp 7 with the tapered upper end a of the seat-post mast will firmly hold it in place and prevent it from turning. At the same time, post may be readily and easily removed without the use of tools for repair or renewal or to adjust it at a difierent elevation. Again, by forming the tongues 6 in the seat-post so that-the tongues 9 of the tapered sleeve or clamp will bear against them throughout their whole length a substantial support is given to said tongues 9, the upper ends of which form the stops 8.
Having thus described our invention, we claim- 1. A seat-post in the stem of which two series of shoulders are formed, in. combination with atapered sleeve or clamp formed in sepboth surfaces being tapered, the seat arate and independent sections, each provided with a stop, and a seat-post mast, substantially as and for the purpose set forth.
2. A seat-post, in the stem of which two series of shoulders are formed, and which is provided with two series of tongues, in combination with a tapered sleeve or clamp formed in separate and independent sections, each provided with a tongue and stop, and a seatpost mast tapered at the upper end, substantially as and for the purpose set forth.
In testimony whereof we have signed in the 30 presence of the two undersigned witnesses.
