F. H. BOLTE.

VBLOCIPEDE SADDLE.

Patented Aug. 18, 1891.`

UNITED STATES PATENT OFFICE.

FRANK H. BOLTE, OF MILVAUKEE, VISCONSIN, ASSIGN OR OF ONE-HALF TO PARKER H. SERCOMBE, OF SAME PLACE.

VELOCIPEDE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 457,964, dated August 18, 1891.

Serial No. 389.888. (No model.)

To all whom it may concern:

Be it known that I, FRANK H. BoLTE, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Velocipede-Saddles; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in certain peculiarities of construction and combination of parts to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a side elevation of a velocipede-saddle, partlyin section, and embodying my improvements; Fig. 2, a front elevation of the same; Figs. 3 and 4, detail sections respectively taken on lines 3 3 and 4 4 of Fig. 1; Figs. 5 and 6, detail views of a portion of one form of reach forming partof the saddle; Fig. 7, a detail section on line 7 7 of Fig. l; Fig. 8, a side View of a portion of a rear spring, shown as part of said saddle; Fig. 9, a detail side elevation, partly in section, and illustrating another form of reach; and Fig. 10,a section taken on line l() 10 of Fig. 9.

Referring by letter to the drawings, A represents a velocipede-saddle post, and adjustably secured on the horizontal arm b of this post, by means of a set-screw c, is the usual block B, that engages the saddle-reach C, the latter being adjustably held in said block by means of another set-screw d, as shown in Fig. 1. Adjacent to its front end the underside of the saddle-reach C is provided with a socket e for engagement with a set-screw f, that has its bearing in a cross-head D, slipped onto said saddle-reach. The cross-head is provided with longitudinal openings or guides that engage the lower rearwardly-extended portions g of springs E, these springs being preferably volute in form and having said portions g thereof offset from the coils, in order that the latter may clear said cross-head, as best illus- Ytrated in Fig. 2, and by this construction and arrangement of springs I obtain an increase of elasticity.

The volute springs E are preferably made from a single rod sobent as to form a yoke h, that engages a hook t' on the polnmel F of the saddle, this pommel and the cantle G being connected by a seat H, of leather or other suitable material, while at the same time said 5 5 cantle is connected in some manner to the rear portion of the reach C, above described, it being preferable to employcoil-springs I for this purpose.

As best illustrated in Fig. 4, the longitudi- 6c nal openings in the cross-head D communicate with the reach-opening of the latter, and consequently the portions g of the springs E in said cross-head impinge against the sad'- 1 dle-reach C, the latter, if made from a round 6 5' rod, being preferably slabbed where it opposes said portions of the springs. The setscrewf being turned in the proper direction, the cross-head D is drawn down to bind those portions of the springs therein firm against 7o the saddle-reach C; but in case it is desirable to adjust said springs in order to take up slack in the seat H said set-screw is run down far enough to loosen said cross-head, but not far enough to come out of engagement with the socket c in said saddle-reach, after which the aforesaid springs are driven forward to attain the desired result, there being enough friction between the parts to prevent these springs from slipping lback in 8o the intervals between blows of a hammer or other tool by which the driving operation is accomplished.

By the foregoing description it will be understood that the cross-headD is always held 8 5 at one place on the saddle-reach C, and that the pommel-supporting springs E are ad'- justed in said cross-head instead of being rigidly connected thereto and movable therewith, as is ordinarily the case in that class of 9o devices to which my invention relates.

If at any time the cross-head is to be detached from the saddle-reach, the set-screwf must be run down out of the socket e in said saddle-reach, and while I have thus far described the latter as a stiff rod it may be in the form of a spring-plate, as shown in Figs. 9 and l0, Without departure from the spirit of my invention.

The cantle G of the saddle is shown as rool preferably provided with sockets y', longitudinal of said saddle', and the upper ends of the coil-springs I are recurved toward the rear to form hooks 7a, that engage the sockets, as shown in Fig. 1. By means of the construction just described the draw of the saddie-seat is always against the hooks at the upper ends of the springs I, and consequently the latter are prevented from becoming disengaged from said cantle by the weight of the rider on said saddle-seat or the taking up of slack in this seat by the forward adjustment of the pommel F and its supportingsprings.

The lower ends of the cantle-supporting springs I are bent to form hooks on for engagement with vertically-disposed sockets in another cross-head J, the latter being provided with a set-screw n, that is run up in a socket in the saddle-reach C, before described.

The vertically-disposed sockets in the rear cross-head communicate with the reach-opening of the latter, and the lower hook ends of the springs I are ground out to form notches fr, that engage the saddle-reach, as best illustrated in Figs. 7 and 8, whereby in the construction and arrangement of parts just described said springs are prevented from being accidentally disengaged from said cross-head.

The seat of a saddle such as I have described will yield only in a longitudinal and vertical direction, as the general construction and arrangement of the parts prevent lateral rocking of said seat on the reach-a fault common to many velocipede-saddles now in use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A velocipede-saddle having its reach provided with a clamping cross-bead stationary in a longitudinal direction and furnished with longitudinal guides that communicate with its reach-opening, in combination with pominel-supporting springs having extensions that engage the guides in the cross-head to impinge against said reach, substantially as set forth.

2. Avelocipede-saddle havingits reach provided with a clamping cross-head stationary in a longitudinal direction and furnished with longitudinal guides that communicate with its reach-opening, in combination with voluted pommel-supporting springs having oit'- set portions that engage the guides in the cross-head to impinge against said reach, substantially as set forth.

3. A velocipede-saddle comprising a reach, a clamping cross-head engaging the same and provided with longitudinal guides that communicate with the reach-opening, springs having portions thereof engaging the guides in the cross-head to oppose said reach, and a seat having its pommel supported by the springs and its cantle connected to the aforesaid reach, substantially as set forth.

4. A velocipede-saddle comprising a reach, a front cross-head engaging the reach and having longitudinal guides that communicate with the reach-opening therein, a rear crosshead also engaging said reach and provided with vertical sockets in communication with its reach-opening, springs that engage the guides in the front cross-head, other springs having notched lower ends engaging the sockets in the rear cross-head, and a seat supported on the springs, substantially as set forth.

5. A velocipede-saddle comprising a reach having a cross-head provided with verticallydisposed sockets communicating with the reach-opening therein, coil-springs having hook-shaped and notched lower ends engaging said sockets and recurved upper ends, a seat having its cantle provided with Sockets for the latter ends of the springs, and suitable means for connecting the pommel of the seat with said reach, substantially as set forth.

In testimony that I claim the foregoing l have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Visconsin, in the presence of two Witnesses,

Y FRANK H. BOI/FE.
