BICYCLE SADDLE-POST.

SPECIFICATION forming part of Letters Patent No. 596,699, dated January 4, 1898. Application i'iled January 22, 1897. Serial No. 620,300. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR L. GAREORD, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvementsl in Bicycle Saddle-Posts; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in direct seat-posts, so called, adapted for securing a bicycle-saddle upon a bicycle.

The object of the invention is to provide a cheap, simple, and easily-operated construction whereby the desired result may be attained.

The invention consists in the construction and combination of parts hereinafter described and claimed.

In the drawings, Figure l is a side elevation of my seat-post complete and in use for clamping the spring of a bicycle-saddle. Fig. 2 is a sectional front elevation on line 2 2 of Fig. l. Fig. 3 is a rear elevation of the post when the clamping-jaws are removed, and Fig. 4 is a detached rear view of said clamping-jaws.

Referring to the parts by letters, A represents the substantially-vertical stem of the post, which is adapted to be secured to the bicycle in the usual manner. upper end of this stem in any appropriate manner is a horizontal tube B, which is cut away upon its top side between its ends, thereby formingl the substantially-vertical ears Z2 b and a recess b between them. The seat support or spring G lies in this recess between said ears, resting upon the tube B. The spring Gis held in the position stated by the clamping-jaws O C', which are relatively movable laterally toward and from each other. Both jaws may be movable in the ears b b, as shown in Fig. 2 in the drawings. In such case the said movement may be effected by means of the bolt D, having a threaded end d, which screws into jaw C', a cylindrical shank d', which passes through the jaw C, and a head d2, which bears against the jaw C and causes it to be moved toward the jaw C.

In the proximate faces of the jaws the grooves c c are cut, which grooves receive and embrace the side edges of the spring G. The top wall of these grooves is beveled substantially as shown, whereby the spring G is Secured to the' clamped down upon the edges of the tube B as the jaws are drawn nearer to each other.

Modifications of the specific form or arrangement shown in the drawings which are within my invention will readily suggest .themselves to one skilled in this art, and I do not wish to be understood as limiting myself to that specific form or arrangement further than the claims require.

Having described my invention, I claiml. In a direct seat-post, the combination of the stem A, two parallel vertical ears on the upper end thereof, two relatively-movable clamping-jaws supported and surrounded by said ears, and means for moving said jaws relatively toward each other to clamp a saddle-spring placed between said ears, substantially as specified.

2. In a direct seat-post, the combination of the substantially-vertical stem, a horizontal tube secured upon its upper end, which tube is cut away upon its top side between its ends to form two ears and a recess between them which will receive the saddle support or spring, two relatively-movable clamping-jaws having in their proximate faces grooves with beveled top walls, and means forrelatively moving said jaws toward each other, substantially as and for the purpose specified.

3. In a direct seat-post, the combination of the stem, and the substantially-horizontal tube on the top of said stem, which tube is cut away on its top side between its ends, thereby forming the ears b b and arecess between them, with two clamping-jaws, mounted in said ears, said jaws having in their inner ends grooves adapted to embrace the edges of the saddle support or spring, and a screwbolt for moving said clamping-jaws toward each other, substantially as and for the purpose specified.

4. The combination, with a bicycle having the seat-post A and a saddle having the supporting-spring G, of the tube B cut away on its upper side and thereby leaving ears b h, the clamping-jaws C and C having the grooves c c, and means for moving said jaws relatively toward each other and preventing their separation, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR L. GARFORD.
