SPECIFICATION forming part of Letters Patent No. 471,798, dated March 29, 1892.
Application led February 3, 1890. Serial No. 339.024. (No model.)
To all whom t may concern.-
Be it known that I, EMMIT G. LATTA, a citi- Zen 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 folthe durability of the driving-wheel bearings,
to render the saddle readily adjustable toward and from the handle-bars in asimple manner, and, finally, to improve the construction of the steering-head.
In the accompanying drawings, consisting of three sheets, Figure l is a side elevation of my improved velocipede with the brake and pedals omitted. Fig. 2 is a front elevation thereof. Fig. 3 is an enlarged side elevation of the central portion of the driving-wheel with the' crank removed and a portion of the bearing-box broken away, showing a pair of spokes in place. Fig. 4 is a sectional elevation of one end of the axle of the drivingwheel and connecting parts. Fig. 5 is a longitudinal section of the reach on an enlarged scale, showing the manner of adjusting the saddle-supporting fork upon the same. Fig. 6 is a vertical section in line l 1, Fig. 5. Fig. 7 is a horizontal section in line 2 2, Fig. 6. Fig. 8 is a sectional elevation of one end of the front-wheel axle and connecting parts on an enlarged scale. Fig. 9 is a cross-section of Vthe spokes in line 3 3, Fig. 3. Fig.1O is asectional elevation of the steering-head on an enlarged scale. Figs. 1]., 12, and 13 are crosssections of the same in lines 4 4, 5 5, and 6 6, Fig. 10, respectively. Fig. 14 is a longitudinal section of the intermediate fork of the driving`wheel in line 7 7, Fig. 10. Fig. 15 is a cross-section in line 8 8, Fig. l0.
Like letters of reference refer to -like part-s in the several figures.
A represents the axle ot the driving-wheel, A the hub-anges mounted thereon, and d the rim of the wheel.
b represents a series of spokes extending from the outer face of the hub-flange to the rim, and b a series of spokes extending from the inner face ofthe hub-flange to the rim at a dierent angle from the spokes of the opposite series.
C represents the upright fork of the driving-Wheel, and D is the bearing-box arranged in the circular opening in the fork end and. having an external screw-thread, which engages with'an internal thread formed in said opening, as represented in Fig. 4.
d represents an adjustable internallythreaded collar arranged upon the outer threaded portion d of the axle and provided with inner and outer cone-bearings d2 d3. This collar is also provided with the usual notched flange d4, with which the retaining-- screw d5 engages ina well-known manner.
e is a stationary outer collar arranged upon the axle outside of the threaded portion thereof and provided with inner and outer cone-bearings e e2.
e3 represents the balls interposed between the adjacent cones of the collars d e and the annular groove of the bearing-box D. The
inner face of the crank F andthe outer face of the hub-flange are recessed, asshown at e4, to receiveV the adjacent cones of the collars d e. As represented in Fig. 3, the outer stationary cone is held against turning by a projection f, formed on the cone and entering a longitudinal groove in the axle. The bearing-box D is held against turning in the fork end by a screw g, arranged in a threaded opening in the fork end and engaging with its reduced end in one of several openings g', formed in the periphery of the bearing-box, as represented in Fig. 3. The bearing-box rests with the upper part of its ball-groove' upon the anti-friction balls, causing the up-i per part of the ball-groove to rst wear out I of true. Upon loosening the holding-screw g the box may be removed from the fork end and reversed therein or screwed into the same from the opposite side, so as to change the position of the boxwhen its grooves are worn out of true and bring the part of the box which was below the axle above the same. and thus equalize the wear. After the box has been replaced it is again secured in position by the screw g.
h represents an oil-duct formed in the fork end and registering with one of the openings IOO g in the bearing-box. The oil-ducth is closed by a cap or cover h, which is secured tothe fork by the screw y. The openings g are arranged at such a distance apart that ono'opening will register with the oil-duct when the screw gis engaged in the other opening in either position of the bearing-box.
l If preferred, the box may be provided with a series of holes extending around the box, which construction permits the box to be adjusted by simply turning it in its seat without removing it from the fork. By making the bearing-box adjustable or reversible in this manner its durability is considerably increased.
Upon removing the crank from the axle one or both of the double cone-bearings d e may be reversed on the axle, so as to bring the opposite cones into play. The anti-friction balls gradually wear a groove into the face of thecones, causing increased friction and eventually requiring a new set of cones, and it frequently'happens that a portion 'of one vof the `cones breaks off, or,.o.wing to a flaw in the metal or poor tempering thereof, it wears unevenlj7 and requires to be replaced bya new one. In .the event of any of ythese occurrences it is only necessary to reverse the defective cone-bearing to bring the unused cone into an operative position, when the bearing will again be as useful and efficient ,as a new bearing. By thus making the cones .doublel and reversible the life of the bearin g is `doubled without materially addi-ng to the weight thereof or increasing its cost.
In case a cone wears outor becomes otherwise `disabled when the rider is in a locality where a new one cannot be obtained this double and reversible feature of the cones is especially important and useful, as an impaired cone can be readily reversed and readjusted without delay and inconvenience, s0 that my improved bearing possesses a greater benefit than the mere saving in the cost of repairs. By seating the short outer cone in the recess formed in the .crank-bars, as represented in Fig. 4, the cone is less liable to split under severe shocks than the short cones having square outer ends, as heretofore constructed.
In the modified construction of the bearing represented in Fig. 8, in which my improvement is applied to the small steering-wheel, a single double cone or collar is employed at each end of the axle, and theouter end of the cone is seated in a recess in the fork-arm. The hub of `the wheel revolves on the axle and is provided i-n its ends with annular bearing-boxes t' in the ordinary manner. In this construction the double cone may be reversed, as in the first-described construction.
In the drawings the bearing is shown as applied to the wheels of a velocipede; but it may obviously be applied to other journal parts of the velocipede. It is also obvious that the movable cone may be adjusted and locked in various ways and that it may be arl fork ends.
the coupling M, and a cones `may be made adjustable, if desired.
. J represents the lower horizontal fork ofv the driving-wheel, and J the intermediate fork.
K is the upper rear portion of the reach, and K the lower front part thereof, the two parts forming the main connecting-frame.
As represented in Fig. 4the lower ends of the upright rear fork-arms C are secured Ito upwardly-projecting lugs 7c, formed on the The lower and intermediate forkarms are connected 4together at their rear ends by a coupling l, and are vpivoted to a forwardly-projecting lug on the end of the upright fork C by a horizontal pivot-bolt l', as represented in Figs. 1 and 3. As represented in Figs. 1 and .6, the armsof `the up# right fork C are united above the drivingwheel by a union or coupling M, which is provided with an opening m, through which the upper part K of the reach passes, the upper endof the ,upright fork C being capable of moving forwardly and backwardly on the upper part of the reach.
Referring to Figs. l, 5, and 7, n represents aspring-cateh secured to the front side of the union M above ythe upper part of the reach and having a bolt or projection n',
which is designed-to ,engagein one of a number of recesses or depressions n2, formed in vthe upper side of the reach., so as to lock the l upper end of the upright fork() to the Teach. The spring-catch n is provided with a forwardly and upwardly curved handle n3, which terminates in convenient reach of the rider, and whereby the catch is raised to disengage its projection from the reach and release the upright fork.
o is a stop or bolt secured to the rear `end of the reach, whereby the upright fork is pre Vented from moving rearwardly off the reach.
P represents the saddle attached to the upper end of the upright fork C.. Upon releasing the fork from the reach the fork, with the saddle, may be adjusted forwardly `or backwardly on the reach in the most convenient position for the rider, thereby enabling him to take advantage of the varying road-surface over which he passes by moving the saddle farther forward on ascending grades.
For expert riders the screw or projection 'n' may be adjusted to project only slightly beyond the spring-catch, so that the saddle-supporting fork may be shifted in either vdirection by the movement of the body alone without raising the catch by hand.
p p represent the front and rear springs of I the saddle, which support the iexible seat. As represented in Figs/1,5, 6, and '7, these springs are each formed with down-ward extensions or posts p2, which pass through vertical openings in the coupling M and are adjustably secured inthe upper ends of the tubular arms of the fork C by upright clamping-plates q q, arranged on opposite sides of horizontal clam ping-bolt IOC IIO
ermesa q', passing through thev coupling and clamp-y ing-plates. The upper portion ofthe coupling M is recessed on opposite sides to receive the clamping-plates, as shown Yin Fig. G, and the clamping-plates are provided in their inner faces with grooves in which the vertical posts of the saddle-springs are seated. Upon loosening the clamping-bolt q the saddle may be adjusted to any desired elevation. As the posts of the two supporting-springs are independent, the posts of the'front spring may be raised and those of the rear spring lowered, or vice versa, so as to tilt the saddle in either direction. Thesprings of the saddle are each preferably composed of a singlepiece of steel wire secured at its doubled central portion to the end of the saddle, both springs extending outwardly and downwardly from the ends of the saddle, and thence inwardly under the saddle, as represented in Fig. l. In case the rider does not desire to shift the saddle while riding the spring-catch n is removed and the screw n thereof inserted in a threaded opening r, formed in the coupling M, so as toA project with its end into one of the recesses of the reach and rigidly secure the upright fork to the reach. Fora cheaper class of machine the upper end of the upright fork may be permanently secured to the reach by brazing, in which case the spring-catch nis omitted, and the rear ends of the intermediate andV lower forks J J are rigidly secured to the lower endr the outer end of the intermediate fork J by a coupling T, which is secured to the adjacent front ends of the fork J and upper reach K by brazing or in any other suitable manner. The lower part K of the reach is provided in its upper end with a stub t, having a square projecting shank t', which passes through a square opening in the coupling T, as represented in Figs. lO and 14, and is secured to the coupling by a screw-nut t2, applied to the threaded upper end of its shank. The arms of the intermediate fork J are preferably constructed of steel rods and are secured to the unions or couplings Z and T by right and left hand threads formed at opposite ends of the rods and engaging in correspondinglythreaded openings or sockets formed, respectively, in said couplings.
U represents the inclined tubular steeringhead, which surrounds the lower cylindrical part K ofthe reach.
U is an upward extension or handle-bar support secured to the upper end of the cylindrical head by a forging u, and U2 is the fork of the front wheel secured to the lower end steering-head, and the handle-bar support'is brazed to a lug a2, formed on the front side of the forging u. The forgings u u are provided with recessed or open flaring ends to form bearing-boxes, inwhich are arranged hardened-steel linings ug.
fu is a fixed cone surrounding thelower end of the cylindrical reach inside of the lower box u', and 'u' is an adjustable cone arranged upon the threaded upper portion of the cylindrical reach inside of the upper box u, and which is held in place by a jam-nut 02.
e3 represents a row of balls arrangedbetween the lining of the box u and the adjustable cone fu', and v4 a row of balls interposed betweenthe lining of the lower box u and the fixed cone fu.
port U. The handle-bars can be adjusted vertically in their support without materially changing their position in front of the saddle. As represented inFig. l5, the neck of the angular coupling S is made comparatively narrow, and the opening w in the upper rear side of the front fork is somewhat enlarged to afford the requisite range of movement to the coupling. 1
