I SKATE.

Specification of Letters Patent; I Patented Sept 21 1915;

i Application filed December 15, 1914. Serial No. 877,384.

To all whom it may concern Be it known that 1, WILLIAM B. HARRELL, a citizen of the United States, residing at Baldwin, in the county of Duval and State of Florida, have invented new and useful Improvements in Skates, of which the following is a specification. v p

The invention relates to skates, and more particularly to the class'of wheel skates.

' The primary object of the invention is the provision of a skate wherein the same will be propelled under the movement ofthe foot of the user, that is to say, correspondingly to the action of the feet when in the act of walking, the skate 'being of novel form so that no excess energy-is employed over that ordinarily required during the act of walking for actuating the skate to propel the same.

Another object of the invention is the provision of a skate wherein the frame thereof is constructed so that it will be ren dered rigid to possess the requisite strength and rdurability', while the foot stirrup is swingingly supported to allow freedom of I action in the movement of the foot of the user of the skate.

A further object of the invention is the provision of a skate whereinthe user on raising and lowering-the legs willactuate the propelling mechanismof the said skate to advance the same, the speed of travel thereof being regulated by the movement of the legs, and the advancement of theskate is not retarded resultant from the dragging of either skate resultant from thrusting either leg of the user backwardlyr in a fashion of skating with the ordinary skates during the continuity of strokes required therefor.

A still further object of the invention is the provision of a skate wherein the user can readily control the travel thereof and also can brake the same for bringing either skate to a standstill either gradually or suddenly, as the occasion may re quire. I

A still further. object of the invention is the provision of a skate of this character which is simple in construction, reliable and eflicient in use, and inexpensive in manu-.

facture. I

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described,illustrated in the accompanying drawings, and'pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a sideelevation of a skate constructed in accordance with the invention; Fig. 2 is a top plan view thereof. Fig. 3 is a front elevation. Fig. 4 is a rear elevation. Fig 5 is a fragmentary sectional view on the line 5-5 of F1g. 2. Fig. 6 is a similar view taken on the line 66 of Fig. 2. Fig. 7 is a side Fig. 8 is a.

U-shaped sections 10 which are disposed in spaced relation to each other at opposite sldes of the wheels B and C, and have their limbs upwardly converging and united through the medium of the bolt members 11, while journaled in the limbs of the sections 10 are the axles 12 supporting the said wheels. the said axles being fixed in the frame in any suitable manner. Located be. tween the front and rear wheels B and C and fastened inthe sections 10 of the frame are cross bolts 13 supporting spacer sleeves 14 which hold the said sections in their spaced relation to each other. I-

Suitably fixed to the spacer sleeves 14 and rising over the front and rear wheels B andG are the forwardand

rear mud guards

15 and 16, respectively, which are also suitably fixed at the point of the unity of the limbs of the sections 10, the guards being of any preferred form.

. .At one side of the front wheel B concentrically about the axle 12 supporting the same, and fixed to said wheel, is a brake band 18, one end of which is suitably fixed to a bracket 19 carried by one section of the frame A, while its opposite end is loosely connected to a stud 20 mounted in the forward end-of a rocking operating lever: 21.

. supported upon a pivot 22 mounted on the frame,while connected to the rearmostend of the lever 21 is a flexible member 23 preferably in the form of a rope,.which carries at its free end a bail handle 24, the same Same 'being fixed to the said drum, while its opposite end'is eonnect-ed to a rocking yoke 27,the rearmostends ofwhich-are swingingly-connected through the medium of piv- -.ots 2-8 to the sections lOof the frame A, and

supported by this yoke is the stirrup E, here'inaf-ter 'fully' described.

The stirrup E comprises a base plate 29 having mounted thereon the respective -toe and heel boxings 30 and'8l,-an d*th-e buckle straps 32 so;that the foot of the user of the skateca'n be 'fastened in the stirrup. Fixed to and depending centrally from the 'base plate 29 is a pivot bearing'33 receiving a pivot 84 which, together with the-connection 35, -sw-ingingly attaches the stirrups E in' place upon the yoke 27, thereby allowing free action of the foot during the-working or propellingof the skate. Suitably supported by the yoke 27 directly beneath the toeand'heel ;portions of the footiE are cushion springs 36 which retard undue rocking of thestirrup whenworking the skate.

Connected to the drum 25 and trained for a distance about the remaining portion of the outer periphery thereof is a coiled retracti-le .springi37which is also'connected to the frame A, and this spring serves to ro tate the drum '25 in a reverse direction to the pulling action of the band 26 on the'loweri ng of the yoke '27 when depressing the sameby the footof the skater.

Fixed tothe rear wheel 'c about :the'aXle 12 is a ratchet wheel 38, whilezpivoted interna'lly of the drum-25 is a ratchet dog or pawl39, which is adapted to ride over the teeth of the ratchet wheel 38 when the drum rotates in one direction but on movement of the drum in the reverse direction the said dog or pawl 89 will lock with one of the teeth of the ratchet wheelSS so as to rotate the Wheel C in unison with the drum 25, wl iichis actuated by the yoke -27 on pressing the same downwardly by the foot of the user of the skate, and in this manner the skate -'is driven forwardly. The dog or -pa-wl39 is acted upon bymea-ns of a spring 40-which is mounted interiorly of-the drum 25 and is designed tohold thesaid dog or -pawl 39in positive engagement or operative relation to the ratchet wheel 38 Within the drum. Prvoted a tthe front end of the yoke 27*isa hanger 41 carrying a cross pin 42 which is engageablewith' the frame A at one tothe frame intermediate the front and rear wheels therein. Fixed to the front wheel 434 concentrically about its axle is a brake 'd-rum tS, over a portion of-theouter periph- --ery 0f which isxtr-ained a brake "band 49 having one end llXBd to one side-of the frame 43, =while itscpposite end is loosely connected to the forward extremity I of a rocking operating lever 50 pivoted at 51 to the frame, while connected 2 to the rearex- -tremity of this lever "50 'is a flexible pull member 52.carryinga hand grip 53 so that the operator of -the skate; can ;pull upon the HIQIIibGI'fi-Z -for the rocking of the lever 50 which f ictional'ly binds the brake band 49 about the drum 48130 control the speed of rotation of the skate, which is :propelled by manipulation of the limbs of the user in the usual- -Wel l known ananner.

Fixed in any suitable manner in the frame extending over the front and :

rear wheels

44 and 45 are the front and rear mud guards 5st and 55, respectively, andfixegil to'ithe rear wheel 45 concentrically about its -a-Xle is a ratchet wheel 56, while pivoted to one side of the frame 43 is a -pawl -or dog '57 which :engages with the teeth of the ratchet wheel for holding the wheelagainst rotation in-one direction, yet permitting the said wheel -to rotate in the reverse direction, the ratchet wheel and-dog or pawlbeing designedto prevent any back "movement of *the'ska-te when in use.

'-Mounted in {the frame 43 and working against the pawls 57 is'a spring 58 which acts *to hold the pawl in positive or operative relation to "the ratchet 56 to avoid any possibility of slight downward movement ofceither of the skates when app'liedto the foot of the wearer and being propelled.

,F-romthe foregoing description, taken in connection with the "accompanying drawkin-gs, it is thought -'t-h-at the construction of *the device will -be clearly understood, and therefore "a chore extended explanation 'has been omitted.
