ICE-VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 485,345, dated November 1, 1892.

Application filed December 7, 1891. Elerial No. 414.323. No model.)

To all whom it may concern:

Be it known that I, MYRON B. Gicsoiwa citizen of the United States, residing at Ukiah, in the county of Mendocino and State of California, have invented a new and useful Ice- Velocipede, of which the following is a specification.

This invention relates to ice-velocipedes of that class known as rear-driving safety-machines, and more especially thereto when constructed and adapted for use upon snow or ice and the object of the same is to efi'ect certain improvements in machines of this class.

To this end the invention consists in an ice-bicycle constructed substantially as hereinafter more fully described and claimed, and

as illustrated on the two sheets of drawings, wherein- Figure 1 is a side elevation of the machine complete, viewed from the right side and showing one of the runners as provided with its sled-shoe. Fig. 2 is a left-side elevation of the framework and guide-rod, showing, also, the pivoted framework held elevated by the coasting device, and, further, showing the brake as being applied. Fig. 3 is a plan view of the machine complete with the exception of the seat. Fig. 4 is a perspective detail showing the loop of the coasting device and a portion of the head and brake-rod and also illustrating the foot-rests. Fig. 5 is a perspective detail of the hub and a sectorof the driving-Wheel.

This improved ice-bicycle com prisesa main framework F, through whose steering-head extends the guide-rod G, carrying the handle-bar H. Runners R support the lower end of the guide-rod and the rear end of the framework, and from the latter rises a standard supporting a seat S.

D is the driving mechanism, on whose shaft is pivoted a swinging or pivoted framework P, carrying the driving-Wheel W, which is covered by a mud-guard M.

To the front end of the pivoted framework is connected the coasting device 0, operated by a device similar to abrake-handle and adjacent one end of the handle-bar, while a brake proper is provided, as at B, which is operated by a brakehandle adjacent the other end of the handle-bar. The details of construction, whether illustrated and described or not, depend to a great extent 011 the fancy of the manufacturer, the wishes of the rider, and the desired selling-price of the finished machine, and hence it will'be under stood that they are susceptible of a great degree of modification without departing from the spirit of my invention. The latter possesses as its principal features the points covered by the claims hereto appended, and even in these some change can be made, as will be understood.

The various parts of the machine as designated by reference letters and figures are each of the specific construction, preferably, described below.

The mainframework F.This is preferably tubular and of drop-steel forging, the body standing nearly horizontal, the rear end 2 being turned down to the rear runner R and the front end being forked, as at 3, and connected by bolting or otherwise with the tubular steering-head 4. From the horizontal body rises a standard 5', which supports a seat or saddle S, that may, of course, be of any preferred construction, and hence needs no further description.

The guide-rod G.This is also preferably tubular, although in cheaper grades of machines it may be solid, as, indeed, can the framework. The body of the rod is preferably straight, as shown, and stands oblique, so that the jars'which the machine receives in running over obstructions may not weaken or wear the bearings of this rod in the steering-head. Said bearings are preferably lo cated at the upper and lower ends of the head, as at 5 and 6, and may be ball, conical, or otherwise.

The runners R.Each runner comprises a skate-shoe 10 of thin strong steel and pivoted at 11 to the lower end of the framework or the guide-rod, which it will be understood is forked, so as to set astride the skate-shoe. In Fig. 1 one sled-shoe 12 is shown as applied to the skate-shoe for the obvious purpose of increasing the length and breadth of the runner, as the sled-shoe is considerably larger than the skate-shoe. The latter is used on ice or thick crusted snow, while the sled-shoe is for softer snowand perhaps slush and sleet. It is provided with a deep groove 13 of a size and shape to receive, the skate-shoe, and the pointed front end 14 of the skate-shoe fits into a socket 15 at the front end of said groove, while the rear end thereof is open, as at 16. After the sled-shoe is applied as shown a screw or bolt 17 is passed through its body and across its groove above the rear end of the skate-shoe to hold the parts together. The sides of the sled-shoe are cut away, as at 18, to permit the turning of the runner on its pivot 11.

The handle-bar H.I do not limit myself to the shape and size of this bar, though it is preferably curved, as shown, and provided with rubber handles, as are common. The bar is centrally secured to the upper end of the guide-rod G and stands in the proper and most convenient position for the rider when sitting on the seat.

The driving mechanism D.I preferably employ a shaft 20, mounted in ball-bearings supported by braces 21, that are connected to the ,main framework, the shaft extending through the forked lower end of the standard 5 and having cranks 22 on its ends, which carry pedals 23. Near the right crank 22 is a driving sprocket-wheel 24, from which a sprocket-chain 25 leads rearwardly to the driving-wheel W,hereinafter described, as is usual in rear-driving safeties. Although not so shown, the entire driving mechanism may be covered by a shield or protector to pret'ent snow and ice and possibly the riders clothing from getting into the same; but these details will readily suggest themselves. The pedals preferably have ball-bearings on the. crank:

ins. p The pivoted framework P.A strong framework 30, approximately-U shaped in plan, has bearings 31 on the shaft20 of the driving mechanism inside the cranks 22, the ends of this framework extending to the rear normally in about a horizontal plane, as seen. From these ends rise rods 32, which support the mudguard M. The bent front end of this framework is bolted or otherwise connected, as at 33, to the coasting device O hereinafter described, whereby the entire framework P can be rocked around its pivot-the shaft 20to raise the driving-wheel when it is desired to coast 01' to depress the driving-wheel when it becomes necessary to apply greater force, as in ascending steep hills.

The driving-wheel I V.In Fig. 5 this wheel is perhaps best illustrated. It comprises duplicate halves, as will be seen, the object being that the halves may work on opposite sides of the main framework and of the rear runner. A shaft 40 is adju's't'ably secured by nuts 41 in slots 39 in the rear ends of the pivoted framework, and on this shaft is mounted, by cone or ball bearings, the double hub 42, whose center is preferably solid and whose two ends 43 are secured to the center by bolts 44 or otherwise. Between eachend of the center and its adjacent end piece is tightly clamped a number of radiating spokes 45,

each of which is preferably of stout tubing for the sake of lightness, with its outer end reduced, sharpened, or pointed, as shown at 46. A ring 47, preferably, also, of tubing, though somewhat larger, connects the spokes near their outer ends and is concentric with the hub, the spokes in the two halves alternating with each other, so that the peripheries of the halves will present as nearly as possible a perfect circle to the ground. If preferred, the hub may be made solid and the spokes threaded thereinto; but the hub should in all cases be of about six inches diameter, for the obvious purpose of giving "greater strength to the spokes. Secured to one end of the hub is a sprocket-wheel 48, over which the chain 25 from the driving mechanism passes and by which power is communicated to the wheel, the sprocket-wheels 24 and 48 preferably differing in size in order that the speed of the machine maybe geared up, as will be understood. A larger or smaller wheel 48 can be substituted to change the gearing by adjusting the shaft 40 in the slots 39, and the chain 25 can also be tightened in this manner when it becomes necessary.

The coasting device O.-Pivoted at 50 to the I right arm of the handle-bar is a lever 5l,having a branched outer end 52, whose arms stand above and below the right handle, and 53 is a stiff rod pivotally connected with the inner end of this lever and leading down in front of the guide-rod G, its lower end being connected by a ball-and-socket joint 54 with a loop 55, (see Fig. 4,) which surrounds the head4 andeis pivo,ted, as atr56, to opposite sides thereof. 57 is a link pivotally connecting the rear end of this loop with the front end of a stout arm 58, which extends to the rear just above the body of the main framework, and is connected by bolts 33 to the front end of the pivoted framework above described. From this arm 58 preferably project the foot-rests 59, which, as seen, are properly located to receive the riders feet, as in coasting.

The brake B.Pivoted at 60 to the left arm of the handle-bar is a brake-lever 61, whose outer end stands above the left handle, and 63 is a small rod pivotally connected with the inner end of this lever and leading down in front of the guide-rod G through eyes or guides 64, preferably carried by the guiderod through the loop 55 and through an expansive spring 65, located between the lowermost guide 64 and an enlargement 66 on the rod to the brake proper. The latter consists of a steel body 67, its front end being pivoted, as at 68, to the lower end of the rod 63, its sides standing outside the forked lower end of the guide-rod G and being pivoted on the bolt 11, which connects said forked end with the skate-shoe and its rear ends being turned down and pointed, as at 69.

The mucZ-guarclll[.More strictlyspeaking, this device is a snow-guard or slush-guard, since the device will hardly be operated or used in the mud. The guard differs from those in general use only as to its width, being, of course,wide enough to coverboth halves of the driving-wheel, so as to prevent any snow or slush which may be taken up by the spokes from being thrown on the operators back. ItfolloWs the curvature of the wheel, is supported by the rods 32, above described, and is connected at its front end, as at 35, with the pivoted framework P, so as to rise and fall therewith.

The operation and uses-To use the ma chine on ice or hard-crusted snow, the sledshoes are not necessary; butif the snow be soft they will be applied in the manner described. The rider, taking his seat on the saddle, puts his feet on the pedals, and through the driv ing mechanism transmits power to the driving-wheel. As the latter revolves, the sharp ened points of its spokes alternately engage the ice or snow and the machine is driven over the ground. Under ordinary circumstances the weight of the pivoted framework and the driving-wheel will be sufficient to embed the points of the spokes enough to give them the necessary hold in the snow or ice; but when a steep hill is reached the operator with his right hand grasps the handle and the lower end 52 of the branched lever 51 and by drawing up on said end he bears the shaft 40 down, and therefore forces the points of the spokes deeper into the snow or ice. On reaching a downgrade, or whenever he desires to coast, he depresses the upper end 52 of this lever, which raises the wheel off the ice; or by applying his feet to the foot-rests 59 their Weight will hold the wheel raised, and the machine will then slide over the ice without the driving-wheel turning at all. At this, or, in fact, at any other time, the brake is applied by depressing the lever 61 and thereby throwing the point 69 into the ice alongside the front runner, and when the pressure is removed the spring will throw this point out of the ice. The steering is, of course, done in the usual manner. If the pivot 11 at the lower end of the guide-rod G passes through the runner forward of the longitudinal center of the latter, so that it can traillike a rudder, it is obvious that the operator could remove his hands from the handle-bar. The machine can be suitably ornamented to make it neat as well as serviceable, and it presents a bicycle which can be used on ice or snow by a gentleman or a lady. By the necessary changes the machine may be made in the form of a tricycle, a sociable, or a tandem bicycle.
