EPHRAIM N. BOWEN. OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-HALF TO "WILLIAM S. BULL, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 334,635, dated January 19, 1886.
Application filed June 10, 1885.
To aZZ whom it may concern:
Be it known that I, EPHRAIM N. BOWEN, of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Exercising-Machines, of which the following is a specification.
This invention relates to an improvement in that class of exercising-machines which are used by bicycle-riders, and are called home- I0 trainers.
These machines consist, principally, of a crank-shaft provided with pedals, a standard in which said shaft is journaled, and which carries at its upper end a handlebar, and a saddle attached to said standard. i
The Object of this invention is to improve the construction of the machine in various respects, whereby it is rendered more convenient in use and better adjustable in accord 2o ance with the requirements of the rider; and
my invention consists, to that end, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.
In the accompanying drawings, consisting of three sheets, Figure l is a side elevation of my improved exercising-machine. Fig. 2 is a front elevation of the same. Fig. 3 is a fragmentary sectional elevation of the lower portion of the standard and connecting parts on an enlarged scale. Fig. 4 is a longitudinal sectional elevation of the saddle. Fig. 5 is a cross-section in line x w, Fig.4. Fig. 6 is a perspectiveview of the saddle-support. Fig. 7 isa horizontal cross-section in line y Fig. 3. Fig. 8 is a side elevation of the registering device. Fig. 9 is a front elevation thereof, with the bell shown in dotted lines. Fig. 10 is a longitudinal sectional elcwation of the shaft and supporting parts. Fig. 11 is a horizontel section of one of the pedals. Fig. 12 is a cross-section of the same. Fig. 13 is an elevation of the outer portion of the pedal-pin on an enlarged scale. Fig. 14 is a 1ongitudinal sectional elevation of the handle. Fig. 15 is a cross-seetion of the same.
Like letters of reference refer to like parts in the several figures.
A represents the base or foot of the machine, which is firmly secured to the floor by screws or other fastenings.
a represents the lower stationary portion of Serial No. 168,176. (No model.)
| the standard, rigidly secured, with its lower end in the base A, and c is the upper movable portion of the standard, which is capable of vertical adjustment in the lower portion, a. The portions a a of the standard are constructed of tubes, the upper portion, a, being made of smaller diameter, so as to fit snugly in the bore of the lower portion, a. The latter is composed of two parts, which are united by a cross-piece or fitting, I), to which are secured short horizontal tubes 1), which project on both sides of the standard and form the bearings for the horizontal shaft 0. The bore of the lower portion, a, of the standard is closed below the shalt c by a plug. 0, whereby the bore or cavity around and above the shalt can be utilized as an oil-reservoir, into which the oil is introduced through an opening, 0', formed in thestandard above the shaft. Thisoil-res- 7o ervoir may be filled with sponge or other absorbent material.
D represents the wheels, secured to the ends of the shaft 0 on both sides of the central standard, and E represents the pedals attached to said wheels.
e represents the pedalpins, secured adj ustably in radial slots 6, formed in the wheels D. Each pedal-pin is provided with a flat neck,
6", which fits in the slot e, and a screw-shank, 8o 0 to which is applied a screw-nut, by which the pedal-pin is secured in the slot.
F represents the sleeve, which is mounted on the pedal-pin and provided with the pedal plates f f. The plates fare made of sheetsteel, and secured by soldering or riveting to the flat parallel faces of the sleeve F, on opposite sides of the pin. These platesfare covered with plates f, of rubber, which afford a strong foothold and form a lightpedal. The c sleeve F is open at its inner end and closed at its outer end, where it is provided with an enlargement or cap, F, which covers the outer end of the pedal-pin.
g is an annular groove formed in the pin .3 5 near its outer end, and g is a ring which is arranged in said groove, split lengthwise, or divided into halves lengthwise, as shown in Figs. 12 and 13. The outer surface of this ring is flush with the pin 0, and it is held to- Ioc gether by a steel spring,
g is a screw which works in a threaderilv lCO t l opening in the cap F, and enters with its inner end between the adjoining; ends of the split ring g, so that by moving the screw toward the pin 0 the split ring; is opened and forced againstlhe bore. of the sleeve F. thereby clamping the ring; to the sleeve l and preventing longitudinal displacement of the latter on the pin (2, while permitting the sleeve to turn on the pin. in this manner the pedal is securely attach d to the pin and the fastening screw released iron: -the greater part of the strain.
H represents the star-wheel of the registering mechanism or cyclometer, which is turned by a pin. 71, secured to one of the wheels I), and checked by a springdetent, h. The wheel H is mounted on a shalt, 71 which is provided with a screwthread, If. The latter engages with a worm-whcel, l, which makes, prel'erably, one revolution for every mile traveled by the circumference otthewheels. The wheel 1 turns loosely on a stud, which is secured to a collar, 1", emhracinglhe standard a. The wheel I is secured to or l'ormed with the bell l, and the outer face of the latter is provided with a grzuluation, upon which the distance is read off by means of a stationary pointer. i". affixed to the stud i. The wheel I is provided with pins j, which operate the striking-hammer j.
K represents the brake arranged to bear against the lower sides of the wheels D D, and hung to a plate, 0, which is attached to the base A.
it are rods which connect the brake K to the lower end of the spring-balance L, whose upper end is attached to a bolt, Z. The latter is supported by a screw-nut, Z, upon thejaws M of a divided ring or collar, M, so that by turning the screw-nut l the tension on the brake can be increased or reduced. The tension applied to the brake can be read off on the graduation of thespring scale, thus al'l'ording ready means for adjusting the resistance according to the requirements of the rider. The collar M embraces the upper end of the lower portion, (r, of the standard, which latter is also divided 'ertically at its upper end, so that upon tightening the screw m, which passes through the jaws M, the upper end of the lower portion, a, is tightened upon the upper portion, a, thereby holding the latterin place, while upon loosening the screw m the upper portion, a, is released, and can he raised and lowered to adjust the height of the machine to the rider. The upper portion, a, of the standai .1 provided with a suitable graduation corresponding with driving-wheels of various diameters, so that the rider can readily adjust the machine to correspond withawheel ot a given diameter.
N represents the saddle, and N the metallic frame or stretcher on which the leather cover of the saddle is mounted.
0 represents a curved supporting-arm or backbone projecting rearwardly from the upper end of the portion a of the standard, and
1 is a metallic bracket, by which the saddleis supported on the arm 0. Thebracket Poonsists of a plate.p, to which the saddle-frame N is attached by a clip. 7), and which is provided on its underside with project ions, which form a concave front hear ng, and similar rear bearingsp", all resting upon thearin O.
q is a clip which connects the rear end of the support-l with the arm 0. Upon loosening the clip the saddle can be adjusted forwardly and rearwardly on the arm 0.
R represents the handle-bu r. sr-cu red to the upper end of the portion a of the standard by a T-piece, 1', or other suitable means. and S are the handles attached to the end of the bar R. Each arm of the handle-bar is provided with a neck or reduced end portion, r, upon which the handle 5 is mounted. Each handle S consists of an open metallic frame, .9, provided with a central socket, s, and a rubber body, .9", which is formed around the frame 8 and fills the open SPILttGSlllQICOf. The socket s is closed at its outer end and tits snugly on the neck r of the handle-bar. The neck 1* is provided near its outer end with an annular groove, 1", into which enters a sliding bolt, t. The latter is titted in an opening, t, formed in the frame 8, and is held into the groove 1" of the neck r by a screw,t. A spring, if, of rubber or other suitable material, is interposed between the screw and the bolt t. The spring t equalizes the pressure which the screw it exerts upon the bolt '1, and the screw 1 is so adjusted that it presses the bolt against the neck 1- with sulficicnt l'orce to hold thehandle stationary on thence-k. cxceptwhen the handle is turned by the ha ml. The handle adapts itselt' easily to the position of the hand, and can be comfortably held in the hand.
