VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 438,551, dated October 14, 1890.

Application filed January 22, 1890- Serial No. 337,741. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, EMMIT G. LATTA, acitizen of the United States, residing at Friendship, in the county of Allegany and State of New York, have invented new and useful Improvements in Velocipedes, of which the following is a specification.

The objects of my invention are to produce a velocipede Which may be used by either sex, to reduce the Weight and cost ot' the main frame and construct the same in such manner as to render it particularly desirable for service on rough roads, to improve the steering mechanism, and, finally, to facilitate the interchanging of the driving-gears.

In the accompanying drawings, consisting of four sheets, Figure 1 is a side elevation of a velocipede containing my improvements. Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal section of the saddle-supports in line 1 1, Fig. 1, on an enlarged scale. Fig. 4 is a cross-section of the machine in line 2 2, Fig. 1, on an enlarged scale. Fig. 5 is afront elevation of the machine. Fig. 6 is a longitudinal section of the reach in line 3 3, Fig. l. Fig..7 is a fragmentary longitudinal section of the mud-guard and the springs attached thereto on an enlarged scale. Fig. Sis a cross-section thereof. Fig. 9 isa sectional elevation of the crank-shaft and connecting parts, on an enlarged scale, the plane of section being in line 4 4, Fig. 1. Fig. 10 is a fragmentaryside elevation of the rearwheel frame, on an enlarged scale, showing the adjusting mechanism of the rear axle. Fig. 11 is a cross-section in line 5 5, Fig. 10. Fig. 12 is a cross-section of the steering-head in line 6 6, Fig. 1, on an enlarged scale. Figs. 13 to l6,inclusive, represent modified constructions of the reversible reach. Fig. 17 is a cross-section in line @o oc, Fig. 14.

Like letters of reference in the several figures.

A represents the front Wheel, A the rear wheel, and A2 the hollow fork or frame ot' the front Wheel.

b b represent upward parallel extensions or continuations of the branches of the front fork and constituting together an open steering-head. These extensions are connected together by cross-heads or bridges b b2, havrefer to like parts ing collars which embrace the extensions, as represented in Figs. 2, 5, and 12.

C C represent independent handle-bars arranged With their Shanks inthe tubular parts b b of the steering-head, and which are adjustably clamped therein by the collars of the upper cross-head b. The collars of thelatter are split and each provided with a lug b3, through which passes a horizontal clampingbolt b4, the lug of one of the collars being provided with a smooth opening, through Which the headed portion of the bolt passes, and the lug of the other collar with a screw-threaded opening, With which the threaded end of the bolt engages, as represented in Fig. 12. Upon tightening this bolt both collars are contracted simultaneously,whereby the upper ends of the extensions b are caused to clamp the shanks of the handle-bars. The extensions b are also split to permit them to contract. The handle-bars are adjusted vertically to any desired elevation by loosening the clamping-bolt b4 and again tightening the same after making the adjustment. The handle-bars are made right and left and eX- tend upwardly from the steering-head parallel with the latter, thence outwardly, and thence backwardly to bring the handles Ainto the same position as the handles of an ordinary transverse bar having rearwardly-bent ends. This construction of thesteering-head and handle-bars requires fewer parts than the usual construction and reduces the Weight correspondingly. It permits of the same vertical adjustment as ordinary handle-bars, and as the handle-bars are separate and movable independently of each other they can be turned backwardly orl forwardly in their sockets to locate the handles in the most comfortable position for the rider.

D represents the reach, and D the steeringspindle, provided with the usual cones or steering-centers, which are seated in bearings in the cross-head or bridges b b2. Instead of arranging the spindle on a line with the steering-head, as heretofore proposed, the spindle is located in advance of the steering-head, as represented in Fig. 1, the inclination of the spindle being such that the planes of the spindle and steering-head intersect, as represented by dotted lines in Fig. 1. By this ar- Tco rangement the handle-bars are brought back to their proper position and the spindle is caused to assume a more desirable angle for easy steering than when the same stands in a plane with the steering-head or in rear thereof. The neck of the spindle is made longer than ordinarily to afford suflicient range of movement to the spindle. As representedin Fig. 1, the neck of the spindle terminates in a socket e, in which the upper front end of the reach D is secured by bra-zing or otherwise. The reach D extends downwardly and baekwardly from the steering-spindle to a point immediately in front of the rear wheel, and is secured at its lower end in a socket formed in a coupling E.

F F represent the upright tubular saddle supports or posts rising on opposite sides of the rear wheel, and which are secured to the coupling E by rearwardly-projecting lugs e, formed on the coupling E and fitting into the lower ends of the posts, as represented in Fig. 6. From the coupling E the tubular saddle-supports are curved backwardly and upwardly and thence forwardly, as represented in Fig. 1, forming with the reacha depressed frame of approximately U form. The saddle-supports are united at their upper'ends by a cross-barf, having a split clamping collar f and a clamping-bolt f2, so that the saddlepillars g, arranged in said collar, may be adjusted vertically.

ZL represents the crank-shaft, which is supported in a transverse dependingjournal-box H, formed on the under side of the coupling E at the lower end of the reach D, as represented in Fig. 9.

i is the sprocket-wheel mounted on the crank-shaft, and z" the sprocket-wheel secured to the axle of the rear wheel and connected with the sprocket-wheel of the crankshaft by a chain Z2 in the usual way. The crank-shaft is provided at its ends with the usual cones h h2, and the journal-box is formed at its open ends with cones having steel linings h3, between which and the cones of the crank-shaft the balls h4 are interposed.

J represents the mud-guard, J the lower fork of the rear wheel-frame, and J 2 the upper fork thereof. The branches of the lower fork J are firmly Vconnected at their front ends by a head or cross-barj, and are provided at their rear ends on opposite sides of the rear wheel with slotted lugs j', in which the axle of the rear wheel is supported. The lower end of the mud-guard is secured to the head or cross-baryl by brazing or otherwise. The branches of the upper fork are secured at their lower ends to the slotted lugs j and at their upper ends to the mud-guard. 7c is a horizontal pivot-bolt connecting the lower fork of the rear wheel to the journal-box H, and which is located in rear of the crankshaft. This pivot-bolt passes through a central opening in the head j of the lower fork, and is secured with its threaded ends in `screw-threaded openings arranged in rearwardly-projecting lugs 7c', formed on the rear side of the journalbox,'as representedin Fig. 9, the bolt being provided with clamping-nuts, which bear against the outer sides of said lugs. The mud-guard J and upper and lower forks J J2 together form a triangular rear wheel-frame, which is pivotally attached to the reach or front frame of the machine by the bolt k, and which is capable of swinging on said pivot toward and from the frontframe.

Zrepresents a series of spiral springs arranged on opposite sides of the rear wheel, and which connect the mud-guard J with the upright or curved saddle-supports F F,form ing an elastic or yielding connection between the front and rear wheel-frames. The springs Z are arranged in pairs-one on each side of the rear wheels-and thesprings of each pair are connected at their front ends by a bow Z', which embraces the mud-guard, 'as represented in Fig. 8. The springs are heldagainst displacement on the mud-guard by a curved plate Z2, secured to the front side of the guard by screws or other means and provided on its inner side with transverse recesses or grooves Z3, inv which the connecting-bows of the springs are confined. The rear ends of the springs are preferably provided with hooks, which are attached to perforated lugs on the saddlesupports F F', as represented in Fig. l. Upon removing one of the fastening-screws of the recessed plate Z2 the latter can be moved outward suiiiciently to permit the springs to be adjusted higher or lower on the mud-guard, to cause the same to counterbalance the riders weight. If the rider isV comparatively light, one or more pairs of springs may be removed, and in case the machine is to be used by a very heavy rider one ormore pairs of springs may be added. The spiral springs Z, in connection with the curved saddle-supports F F', also serve as an efficient dressguard without requiring any additional parts or incurring extra expense.

By locating the joint k of the frame in rear of the crank-shaft the drive-chain is caused to slacken slightly at the instant that the wheel strikes an obstruction, thereby materially relieving the driving-gear from strain. This arrangement also causes the rear wheel to swing forwardly and upwardly on the conneetiug-joint in passing over an obstruction, the springs acting to push the wheel backward against the obstruction in passing down over it, thereby assisting in the forward propulsion of the machine and preventing side slip to a certain extent. A further advantage of this construction is that a rigid connection is obtained between the support of the crank-shaft and the saddle and reach, which materially reduces the wear of the connecting-pivot.

Each slotted lugj of the rear wheel-frame is provided above its slot with a horizontal rack-bar m, and the rear axle is provided near opposite ends with pinions m m', which mesh with said rack-bars, so that by turning the IOO TIO

axle in the lugs it willbe moved forwardly or backwardly and the tension of the drivechain adjusted accordingly. These pinions are held against turning on the axle by a tongue and groove on the respective parts, as represented in Fig. 10, or by other means. The ends of the axle are made square or flatsided, so that the axle may be turned by a suitable wrench. In adjusting the drive-chain the check-nuts m2, applied to the ends of the axle, (shown in Fig. 11,) are irst loosened, preferably just sufficiently to permit the axle to be turned by using a little force. This movement of the axle is transmitted to both pinions m', causing both ends of the axle to be moved backward or forward simultaneously and uniformly. After the axle has been shifted to properly adj ust the chain .the checknuts on the ends of the axle are again tightened. By this construction the adjustment is effected rapidly and accurately, and the rear wheel is held in the center of its frame and prevented from getting out of place, even if one of the check-nuts of the axle becomes loose, the axle and wheel being retained in place so long as the other check-nut is tight.

The journal-bearings of the axle are of the ordinary type, having a single row of balls, and are adjusted in the usual manner by means of the cone n, Fig. 11, Without disturbing the chain adjustment, as but one of the check-nuts of the axle is required to be loosened to adjust the bearings. The pinions m also serve the purpose of the usual washers employed in this place, so that no extra parts are required for the chain adjustment.

O represents one of the cranks, which is formed integral with the crank-shaft, as represented in Fig. 9, and O is the other crank detachably secured to the opposite end of the shaft. By forming one of the cranks in one piece with the crank-shaft the weight of one joint is avoided. The inner portion of the detachable crank is arranged inside of .the sprocket-wheel t', while the hub of the latter occupies the place usually occupied by the crank. The web of the sprocket-wheel is dished or made concave, and the inner portion of the crank is' bent or offset and passes through the web of the wheel to permit of this relative arrangement of the parts and locate its outer portion outside of the rim of the sprocket-wheel. This construction and arrangement Apermits the sprocket-wheel to be removed and another substituted therefor without necessitating the detachment of the crank or disturbing the adjustment of the crank-shaft bearings.

Referring to Fig. 1, Q represents a reversible brace or auxiliary reach connecting the main reach with the saddle-supports F F and having its rear portion forked or bifurcated to straddle the front portion of the rear wheel. This auxiliary reach is attached at its flattened front end to the socket e of the steering-spindle by a bolt q. The socket c is preferably provided 'on its upper'sidewith av tongue or rib q', which enters one of two grooves arranged in Opposite sides of the flattened portion of the auxiliary reach, as represented in Fig. t, whereby the latter is pre vented from twisting or moving laterally on the socket. In the position represented in Fig. 1 the reversible reach extends downwardly and rearwardly, and thence upwardly to the saddle-supports, to which latter it is detachably secured bya clip r, brazed or otherwise secured to said supports, and transverse bolts passing through the rear end of the reach and perforated lugs formed on said clips, as represented in Fig. 1. The central depressed portion of the auxiliary reach is de tachably secured to the main reach by a similar clip r and a connecting-bolt, When in this position, the auxiliary reach forms a depressed truss, Which admits of the machine being used bya woman, while serving to sufiiciently brace the frame to enable it to resist the Various strains to which it is subjected. Upon removingthefastening-bolts of the auxiliary reach the same may bereversed and placed in the position represented by dotted lines in Fig. 1,the ends of the reach being secured to the socket e and clip 'r in both its raised and lowered positions,'while its central portion is detachably secured to the upper ends of the saddle-supports F F by theclamping-bolt f2, as shown. In this raised position the auxiliary reachconsiderablystrengthensandstiffensthe main frameand renders the machine especially servicable for a man upon rough roads.

In the modified construction represented in Fig. 13 the form of the auxiliary reach is substantially like that shown in Fig.`1; but the upper fork of thev rear wheel-frame instead of being connected with the mud-guard is attached to the saddle-supports where the auxiliary reach is united to the latter.

In the modification illustrated in Fig. 14 the front end of the auxiliary reach is journaled in a socket s, formed on the steeringspindle, and the rear end thereof is attached to the outer end of an upright bar S, which latter is pivoted at its inner end to the front side of the saddle-supports, so that the reach may be swung upwardly and reversed, as represented by dotted lines in Fig. 14. The front end of the reach is held in its socket by a transverse pin arranged in the socket and entering an annular groove in the end of the reach. rlhe rear portion of the reach is preferably secured in either position by a springcatch S3, arranged in the end of the tubular reach and engaging with either of two clips s s2, secured, respectively, to the upper and lower portions of the saddle-supports. If desired, a fastening-bolt may be employed in ad'- dition to said catch. This construction of the auxliary reach is cheaper than that shown in Fig. 1 and permits of a more rapid reversal of the reach.

In the modification represented in Fig. 15

IOO

IIO

' the main reach D is made reversible and the upper fork of the rear wheel forms a continuation of the same.

T is a iixed brace connecting the upper end of the steering-post with the front end of the rear wheel-frame. The reversible reach is forked to permit it to straddle the fixed brace T in either position, and is detachably secured at its front end to the spindle-socket e, preferably by two bolts, as shown, at its central portion to the saddlesupporting post and at its rear end 'to the -lug at the rear end of the rear wheel-f rame.

In Fi g. i6 is illustrated another modification of the reach, in which the latter consists of two reaches or perches constructed exactly alike, so that when in a depressed position One of the reaches they stand side by side. is permanently secured at its front end to the steering-spindle and at its opposite end to the rear wheel-frame, while the other member of the reach is reversible and attached at its front end to the spindle by two bolts, at its l central portion to the fixed reach by a connecting-bolt u and .at its rear end to the rear wheel-frame by a bolt u. The fixed rear wheel-.frame consists of an upper arm V, 1arranged on the left-hand side of the wheel, and a lower `arm V on the opposite side of the wheel, both of these arms being secured at their 'front ends to the saddle-support and terminating at their rear ends in a slotted lug for receiving the axle. The rea'r portion V2 of the reversible member of the reach `also forms a part of the rear wheel-frame, being located on the left-hand side of the wheel when in a lowered position and on the righthand side thereof when in a raised position. This reversible feature of the reach is capable of many variations, and also applicable to tandem velocipedes, and I do not, therefore, wish to be confined to the forms herein 'shown Vand described.
