SPECIFICATION forming part of Letters Patent No. 526,655, dated September 25, 1894.

Application iiled October 23. 1893. Serial No. 488,922. (No model.)

To all whom it may concern,.- y

Be it known that I, ALEXANDER AsBUeY JOHNSON, a citizen of the United States, re-

` siding at Clarksville, in the county of Montgomery and State of Tennessee, have invented a new and useful Skate, of which the following is a specification. I

My invention relates to improvements in skates; and the objects in view are to provide a combination ice and roller-skate; and to adapt the same to be readily changed or converted from the one to the other; and to provide for a ready adjustment of the skate to the shoe of the user and securement thereto. With these and various other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawings:-Figure 1 is a perspective View of a skate constructed in accordance with my invention, the same being designed for use upon ice. Fig. 2 is a similar view, the skate being designed for use as a roller skate. Fig. 3 is a transverse sectional view through the front truck or rollers. Fig. 4 is a longitudinal sectional View of the skate. Fig. 5 is a perspective view of a front runner-section of the skate. Fig. 6 is a bottom plan view of the skate, the runners being removed. Fig. 7 is a detail in perspective of one of the front trucks with the wheels removed. Fig. 8 is a similar view of the rubberfcushion employed therein.

Like numerals of reference indicate like parts in all the figures of the drawings.

In the practice of my invention I employa foot-rest, comprising separate plates or sections, of which 1 designates the toe-plate and 2 the heel-plate, the latter having its front end upturned to form the flange 3 for embracing the'face of the heel. The heel and. toe-plates are provided with the usual openings through which extend studs 4 from the runner of the skate, said studs beingheaded to prevent the separation of the members.`

To the center of the under side of the toeplate l is pivoted by means of the above mentioned stud a pair of levers 5, which arearranged at an angle to each other. In front and in rear of these crossed levers and pivoted by similar studs 4a are pairs of short independent levers 6 connected to the extremiof a pair of levers 10, the outer ends of which are loosely connected by means of pivots 11. A hand lever 13 is pivoted on the outer front rivet 9, and locatedl eccentrically upon said klever is a threaded post 14, a second post 15 serving as the rear pivot 9 at the outer side of the skate. These posts arethreaded in reverse directions, and are connected by an intermediate adjusting screw 1G. By operating this screw it will be seen that the levers 5 may be adjusted toward 0r from each other at their outer ends to adjust the sole clips 12 closer to or farther from the side edges of the toe-plate to accommodate soles of dierent widths. The hand lever 13, it will be understood, is swung to the front when the adjustment occurs, and after the adjustment and the application of the foot-rest to the foot, said hand-lever is swung to the rear thereby causing the parts above described to work in toggle fashion, and by reason of the eccentric pivot of said lever cause the sole-clips 12 to move inward and firmly embrace the soleI of the shoe. If desired a'heel-strap may be employed for the heel-plate, and in fact straps may be substituted for the securing mechanism, or clamping devices above described for the toe-plate, but I prefer, however, to employ a similar mechanism at the rear end or heel plate of the skate. To a central stud, by which said heel-plate is secured to the runner, are pivotally connected the levers 20,

' and in front of the same is arranged apair of independent levers 22, which are connected at their outer ends to the corresponding extremities of the levers 20 by means of links 21, rivets 23 serving to form the pivotal connections between said parts. A pair of links 24 are pivoted, as at 25, to the rear ends of the levers 20, and at their inner ends are connected by the pivot 26, upon which is mounted a forked heel-clip 27. A handlever28 is pivoted at 29 to the rear end of a lever 2O at the post 30. A similar post 31 serves as the pivot 23 at the front end of the other lever 2O at said outer side of the heel-plate, and the two IOO posts, which vhave their bores reversely threaded, are connected by a right and 'left' threaded bolt 34. It will be seen that by operating this bolt the two levers in the manner heretofore described may be adjusted to carry the heel-clipfrom or toward the heelplate, and by swinging the lever 28 toward the plate the clip is caused to coact with the flange 3 to clamp the heel of ashoe upon the heel-plate. clips 27 and l2 with the clamping mechanism insures the automatic adjustment of the clips to the curvature or contour of the sole and heel of the shoe. 'i

The runner consists of a front portion V35 and a rear or heel portion 36, which are secured respectively as above indicated to the heel and toe-plates,and are with said heel and toe plates adjustable'toward and from each other to vary the length of -theskate The runner section 35 -isprovidedinE one side with a longitudinal'recess 38, extending from its rear end .to-a point adjacent to its-front end, and the bottom of this recess is grooved, as shown at 37. A pin 39vprojects from the bottom of this. groove near-itsfront end, and in the recess islocatedl a metal=strip 40 having a perforation-at its front end to =receive said pin 39. This strip is further provided upon its inner face witha groove-.4l'correspending-with` the groove inthe bottom of the recess 38, and said recess is spanned at its rear end by a cross-bar 42 having a threaded perforation in whichis fitted a binding screw 43 adapted to bear uponthe outer surface of the strip-40, which is preferablyv of rstrong metaltopress-the freerear end of the latter inward orA toward the ioor of. the recess-38. The plate'35 is provided with one ormore teeth .44, which stand outward toward the strip 40.

v The rear runner section 36 is provided-at its front end `with a forwardly disposed stem 45 provided upon opposite sides with longitudinal ribs 46,- whichcorrespond with Ithe grooves formed in the opposing faces of the strip 40 andfthe runner 35,- whereby when said stem is fitted `in the recess 38,\said ribs 46 iit snugly inthegrooves 4ll andl 37. This stem is `provided with a series of notches 47 to receive the teeth 44 which are normally heldin engagement `therewith-'by the pressure of the binding-screw43 upon the outer surfaceof the-strip 40. -v It is preferableto round the front ends of both runner sections to avoid unnecessary friction with the surface of the ice.

Thismay complete the construction ofthe skate, as I contemplate manufacturing both as an ice skate exclusively and as a combination roller and ice skate, but I prefer^to=pro vide the above described construction with attach ments, whereby the skate may be adapted for use as a roller skate,said attachments being asfollows: Each runnersection-35 and'36l is-provided withhorizontal superficial ribs 48 terminating at their rear ends in shoul- The pivotal connection of theV ders 49, and these ribs are adapted to engage the vframes 'respectively of front and rear trucks provided with suitable rollers or wheels. rIhe construction of said front and rear trucks is identical, and hence it will be necessary to describe but one.

50 represents a U-shaped casting, the inner surface of the vertical walls or terminals of which are grooved horizontally adjacent to their upper edges, as shown at 51 for the reception of the horizontal ribs 48 above described. The rear edges of these castings "when adjust-ed upon the runner sections bear against the terminal'shoulders 49 of -the ribs, vwhich form suitable fixed means for conveying the forward movement imparted to-the foot-rest by the wearer to the trucks. The -casting isjprovided at opposite `sides and ad- :walls with forwardly extending perforated ears 52, which are adapted-to register with a perforation 54 in the runner section for the reception of` a fastening screw 53. Thus vthe screw prevents the detach-ment of the truck from the runner section by a forwardmovement withrelationthereto,but doesnot bear the strain ofi-the forwardy .motion in the use of-the skate. This strain is sustained entirely by the yshoulders 49 at the rearends of the ribs. yThe casting is provided adjacent to the lower end with a vertically elongatcd,hori zontally disposed bearing opening 55, which communicates lwith the 4space between the side walls or cheeks of the casting, and in this bearing opening is located a transverse axle 156 carrying the rollers'or wheels 57. kThe walls orl terminals 50 of the casting below the zplane of the grooves 57 are cut away or recessed, as shown at 58, and fitted betweenthe Iwalls or terminals of the castingabove and bearing upon the transverseaxle, and with its yupper surface in contact with the shoulders at the upper sides of the-recesses 58, is a rubfber cushion 59, which allows a rocking movement of the body-portion of the skate with relation to the rollers or'wheels bythe coin- 4pression of this cushion. Furthermore, said cushion ser-ves to absorb the vibrations of the rollers or wheels, caused by irregularities in the surface overwhich the skate passes.

I do not. limit myinvention to the details -f of construction herein shown and described, ibut hold that I may vary the same to any degree and extent within the knowledge of the skilled mechanic.
