BICYCLE.
SPECIFICATION forming part of Letters Patent No. 324,264, dated August l1, 1885.
Application filed April Q9, 1884.
To all whom, it may concern:
Be it known that I, EMMrr G. LATTA, of Friendship, in the county of Allegany and State of New York, have invented new and useful Improvements in Bicycles, of which the following is a specification.
The object of my invention is to secure the crank and handle-bars in such manner that in case of a fall they will be detached from the ro machine by the breakage of the attaching device, thereby avoiding the breakage of or in- Y jury to the same, and saving the more expensive parts of the machine;also, to prevent the crank and handlebars from working loose,
and to provide means for removing the same readily, if desired; also, to provide means for adjusting the handle-bars at different positions, also, to secure the adjustment of the steering-head without the employment of an 23 outside check-nut, and to construct the dustcap over the steering-head centerin such manner that the center can be oiled without removing the cap; also, in securing the crank in such a way that the means for securing it also serves to adjust the bearings; also, to attach the bearing tothe fork or frame in a way that will preventY it from working loose at the joint, and at the same time provide a universal coupling between the fork and frame, whereby the machine will run free at all times; also to improve the construction of the brake.
My invention consists to these ends of the improvements in the construction of the machine,whicl1 will be hereinafter fully set forth,
3 5 and pointed out in the claims.
In the accompanying drawings, consisting of two sheets, Figure l is a vertical section of one end of the axle and parts connected there with. Fig. 2 is a vertical sectional elevation in line a; w, Fig. 1. Fig. 3 is a horizontal section in line x fr, Fig. 2. Fig. 4 is a perspectiveview of the wedge interposed between the crank and axle. Figs. 5 and 6 are vertical sections showing modified constructions of the device, whereby the crank is attached to the axle. Fig. 7 is a vertical sectional elevation in line x x, Fig. 5.

Fig. 13 is a vertical cross-section showing a modified construction of the handle-bars. Fig. 14 is a cross-section in line x x, Fig. 18. Fig. 15 is ahorizontai section in line y y, Fig. 2. Fig. 16 is a side elevation of the crank and axle on a reduced scale.
Like letters of reference refer to like parts in the several figures.
A represents the axle, provided with flattened inclined ends ce, and B the crank provided with an inclined inner end, b, overlapping the inclined end a of the axle.
C is a wedge or inclined key interposed between the inclined ends a andb of the axle and crank, and attached to the inner end of a screw, c, arranged axially in the crank B,and working in a threaded opening in the wedge C, the head of the screw bearing against the outer side of the crank.
D represents a sleeve whereby the crank is connected with the axle, the sleeve being provided with an outer screw-thread, d, whereby it is attached to the hub of the crank, and an inner screw-thread, d', whereby it is attached to the hub D', secured to the axle. One of the screw-threads, el, is aright-hand thread andthe 8o other a left-hand thread, so that by turning the sleeve the axle and crank will be drawn toward each other until the overlapping ends a b are iirmly clamped against the adjacent sides of the wedge C. The wedge C may, however, be omitted, and the overlapping ends ot' the axle and crank may'be fitted directly against each other.
Instead of a right and left hand thread, one end of the sleeve may be provided with a ne 9o thread and the other with a coarse thread, or a thread of greater pitch, whereby the same result will be attained, the essential feature of this construction being'the connection of the axle with the crank by a sleeve provided with 9 5 differential screw threads, so that the two parts are drawn toward each other by turning the sleeve. The end ot' the axle may project into the crank, as represented in Fig. 5, or the axle and crank may lap against each other :oo
Within the sleeve, as represented in Fig. 6, or a hollow axle may be used-such as is de- Jro scribed in Letters Iatent No. 280,633, granted to me .Iuly 3, ISSS-and the ends of the cranks may be secured in the center of the wheel.
The object of lapping the crank and axle within the sleeve is to make the sleeve the weakest part of the axle, and cause the sleeve to break in case of a heavy fall, which would otherwise break or bend the axle or crank. rlhe sleeve can be more cheaply replaced than either of these parts, and as it is small an extra sleeve can be carried to be used when a sleeve is broken. This method of securing the crank to the axle gives a larger bearingsurface, and the crank is therefore not liable to wear loose, and it also avoids the use of the usual cross-keys, the ends of which are in the way, and produces a more sightly finish. The end of the sleeve is made of any desired form to receive a tool or wrench for turning it. I prefer to make one end of t-he sleeve larger than the other, with an internal screwthrcad, the outside being made in the form of a screwnut. This end of the sleeve can be screwed onto the hub ofthe crank, or to a projection of the wheel-hub, or directly to the axle. The outer enlarged end of the sleeve D is provided on its inner side with a cone, e, which forms the adjustable part of the bearing.
e represents the inner cone, and c2 the balls interposed between the cones e e and the bearing-box E. The cone c' may be niadc separate, as shown in Fig. l; but for cheap work it may be formed in one piece with the hub D', or with the hub of the crank B. Both cones may be made separate from the sleeve D, if desired. XVhen the bearings require to be adjusted, the screw cis unscrewed slightly to permit the wedge C to be pushed back, and the sleeve is turned enough to take up the wear and at the same time again secure the crank to the axle.
In the case of bearings adjusted in the box ihe cones arc omitted and a simple groove is formed around the center of the sleeve, and both ends ofthe sleeve are provided with internal screw threads, while in the case of parallel bearings both ends of the sleeve can be made of smaller size and provided with external screw-threads engaging in threads in the whecl-hub and the cranloliub, or with internal threads engaging with the two parts of the axle.
I am aware that a sleeve to receive the wear has been used; but such a sleeve was loose on the axle or secured to the axle between the hub and crank. This is essentially different from the construction hereinbefore described, in which the sleeve is employed for securing the crank to the axle, and in which the sleeve serves as a safety-coupling, which saves the more valuable parts ofthe machine.
F represents the inner arm of the fork or frame which straddles the wheel. The lower portion oi' thc'fork F is bifurcatcd, as shown at F, and embraces the bearing-box E. The latter is provided on its underside with alug,
E', extending downwz'trdly between lugs F2, formed at the lower ends of the bifurcatcd portion F ofthe fork F. The box E is se cured to the `fork F below the axle by a hori- Zontal bolt, y. This construction prevents the joint from working loose, which it usually docs when located above the axle. The outer edges of the bearing-box are preferabl y rounded off so that the fork can spring in or out without touching the box, except at the shoulders 7L, where the bearing and fork are in close contact to prevent the bearing from tipping backward or forward. The upper surface, I'I, of the bearing E is made spherical concentric with the center of the bolt g, and the fork is provided with ahspherical bearingsurface, Il', resting on the spherical top H of the bearingbox E. The lug E', at the lower end of the box, is made cylindrical, as shown in Fig. 3, and provided with a central opening,I, through which the bolt q passes. The bolt-holes in the lugEare made flaring outwardly to permit the fork to swivel on the lug. The shoulders h on the bearing-box are made in the form of cylinder-segments, and the corresponding shoulders, h, on the fork are made straight, as represented in Fig. 15. This construction permits the fork to turn or swivel slightly on the box without clamping the box on the balls, and the spherical top of the box permits the upper part of the fork to spring in or out, the bolt acting as a pivot. The bolt r/ is placed in front, or outside of a line drawn through the balls, as represented in Fig. 1, to bring the bolt in line with the fork and in the direction of the greatest strain.
In the construction represented in Fig. 8 the pivot I is omitted, and the saine result is attained by making the bolt-hole through the lug E flaring from the middle toward both ends. This construction is simpler than the construction represented in Figs.l 2 and 3, but is liable to wear loose. The wear can, however, be compensated for by forming the tlaring bolt-hole in a bushing seated in a straight opening formed through the lug Il', as represented in Figs. G and S, and this bushing can be renewed from time to time, as may be required.
In the construction represented in Figs. 5 and 7 the box can adjust itself on the balls in one direction only. In this construction the lug E is made with lat sides and fits between the ilat forked ends. This construction, although notas desirable as the constructions hereinbefore described, is still an improvement on the usual construction of attaching the bearing to the fork above the axle, and forms a very secure joint, which is not liable to wear loose.
It is obvious that this method of attaching the bearing to the fork is applicable to tricycles as well as bicycles.
J represents the front portion of the reach or backbone provided with the centers j j in the usual manner.
K represents the steering-head, formed with IOO a center-bearing, k, in which the lower center, j, rests.
L represents the upper adjustable centerbearing, which rests on the upper center, j. The bearing L is provided with an external screw-thread which engages in a threaded opening in the upper part of the steeringhead K.
Z is the oil-passage formed centrally in the bearing L above the center j, and provided with a lateral branch, l', which opens on one side of the bearing L.
M is a dust-cap, adapted t close the openening of the oil-duct l', and provided with a screw, m, which screws into a threaded opening arranged in line with the oil-duct Z. Vhen the dust-cap M is screwed down, as represented in Fig. 9, it closes the opening of the oil-duct l. By slightly unscrewing the dust-cap it uncovers the opening of the oil-duct Z without requiring the dust-cap to be disengaged from the bearing L` thereby avoiding the danger of losing the dust-cap.
N N represent the handle-bars, and N the horizontal lug, to which the handle-bars are l secured by screw-threaded sleeves O.
P represents a block arranged in the lug N between the inner ends of the handle-bars N for the purpose of connecting the same. This block or bar P is provided with inclined ends p, which are closely drawn against the inclined ends 'aof the handle-bars by the screw-threads in the sleeves O. The latter are each pro- 'vided with aright and left handscrew-thread, or with screw-threads of different pitch, as described with reference to the coupling-sleeve D, by which the cranks are attached to the axle, so that by turning the sleeves O the handle-bars are firmly drawn against the intermediate block, P, and secured in place. The sleeves O are made so light that-in case of a fall they will break before the handle-bars are broken or injured, thereby saving the handlebars and steering-head.
Q represents a polygonal or fiat-sided collar formed centrally on the block P and arranged in a mortise, q, of the lug or sleeve N.
R represents a wedge interposed between the collar Q and the adjustable center-bearing L, in the mortise q, and r is a set-screw whereby the Wedge R is adj usted. After t-he centerbearing L has been adj usted to properly rest on the center j the wedge R is firmly clamped against the bearing and the collar Q, thereby securing both the bearing and the handle-bars 1n position. This device for securing the adjustable center-bearing L dispenses with the use of an outside check-nut and permits a closer build of the steering-head.
When the handle-bars N N are formed in one piece, the fiat-sided collar Q is formed directly on the handle-bars. The intermediate block, P, may be omitted and the inner ends of the handle-bars may be constructed to overlap each other and fit against the wedge R.
In thc construction represented in Fig. 13
the intermediate block, P, is formed in one piece with the steering-head, and its ends are serrated or notched and fit into correspondingly serrated or notched ends of the handlebars, the latter being connected to the serrated ends of t-he intermediate. block by sleeves O, as above described.
S represents the brake spoon or plate, provided with a bifurcated rear end, S, which straddl es the front portion of the steering-head K, and is pivoted to the sides of the latter by screws S2. The bifurcated arms S extend upwardly from the pivots S2 along both sides of the steering-head, and are attached at their upper ends to the brake arm or lever T.
t represents a spring whereby the brake S is held in an elevated position. The rear end of this spring is seated in a mortise formed in the front side of the steering-head K, and its front end in a mortise on the under side of the brakespoon S. The spring t is arranged between the arms of the bifurcated portion S', whereby the spring is concealed from a side view. This construction of t-he brake permits the brakelever to be snugly fitted-to the front end of the steering-head, and gives room for the set-screw r, and renders the brake more convenient and more sightly.
