IMPROVEMENT IN SKATES.
To ALL wHoM IT'MAY ooNoERN;
-Be it known that OLIVER G. BRADY, of thc city and county of New York, in the State of-New York, did invent certain new and useful Improvements in Means for Attaching Skates to Boots, for which improvements Letters Pat-oni of the United States were issued to saidQBRADY on the' twenty-third day of September, 1862,
.and numbered 36,503; that said Letters Patent, by a deed of assignment, duly executed and recorded, were conveyed to me, PHINEAS SMITII, of the city of New York aforesaid; andr that having been advised by counsel learned in the law that said Letters Patent are inoperative and invalid, by reason of a defective specification, I have applied to the Commissioner of Patents to issue to me, for said invention, new Letters Patent, under an amended specification; and I do hereby declare that the following is a full-'and exact description thereof, reference being had toA the accompanying drawings, making a part of this specieation, in which- Figure 1 is a side elevation of a skate-iron furnished with my improved fastenings. Figure 2 is a. transverse section through fig. 1,'in the vertical plane indicated by the red line z zethereon Figure 3 is a transverse section through fig. 1, in the vertical plane indicated by the red line yy thereon. Figure 4-is a top view of the heel part of the skate shown in iig. I Figure 5 is a bottom view of the front attachment. Similar letters of reference indicateecorresponding parts in the several figures.
'To enable others'skilled in the art to make and use my invention, I will procced'to describe its construction and operation.
A represents the skate-iron, which is bent in the shape represented 'in iig. 1 of the drawings, the ends thereof being turned up and curved over, so 'as to form 'respectively the heel and toe-supports. B represents the heel-stand, which is of a suiiicient size to give a firm bearing for the heel of `the boot, and C represents the sole-stand, which may be covered with leather or other suitable yielding substance. These two plates, B and C, are rivetedgsecurely to thc -upper portions ofthe skate-iron Aand they form the supports furthe boot when the skate isi-secured to it.A The front edge, b, of the heel-plate B, is turned up, as shown in figs. l, 3, and 4 of the drawings, and a slot, z', is formed in this turned-up portion, for receiving a tenen-projection, d, which is on a shank-plate, D, when the skate is secured to the boot, and preventing the boot, atrthe heel, from having any lateral play on the heel-plate B. E represents a hooked portion, which is of suitable length, having a mulescrew thread cut on its lower cud. This screw portion E is passed down through a hole, 'which is made vertically through the-end of the iron, A, in frent'of the heel-plate B, as shown in figs. 1 and 3 of the drawings, and on the lower end of'this hooked screw E is a thumb-nut, F. D represents the shank-piece, which is suitably secured to the shank of the boot, directly in front of the heel of the boot, as shown in iig 1 of the drawings, wherein the red lines represent the sole of a'hoot to which the skate is fastened. This shank-portion D has an eye, in it, for receiving thehook E, as shown in iigs, 1, 3, and 4, and has also a tenen, d, projecting from its back surface, which tenori lies up` against the inside surface of the heel of the. boot, leaving a space .on each side of the tenon d, sufficient to receive the turned-up edge b of the heel-plate B. Then when the heel of the boot is put upon the plate B, and the ten'on d passed into the slot z', in the edge b, the hook on portion E is passed into the Aeye in the shankfportion D, and by means of. the nut F, the hooked portion E can be set up light, and the skate secured rigidly to the heel of the boot. The objection to skates hitherto used, having fastenings which secure them to the sole'and heel of -the boot,lis,`that in the ordinary movements and exertions of skating, the heels of the boots are frequently strained and twisted off. But it will be seen, from the above description of my improved heel-fastening, that th'e skate is not secured to the heel-of the boot, butto lthe shank ,Y
of the boot, in advance of the heel, and so near to the heel that thegshank will not be strained or injured in the l least. The plate D, which is secured to the shank, is not subject to any wear in using the boots for ordinary purposes, and this is another advantage attained over other sliate-fastenings which have plates secured to the surface of the-heel, and which are soon wornout, rendering the fastening useless. y
The fastening for attaching the skate to the sole of the boot, under the ball of rthe foot, consists of two slotted clamping-jaws, J J, shown in figs-1,2, and 5, of the drawings. `Each has aV serrated griping-portion, j, and an ear-portion, j', and is formed by turningup one end of a straight piece of metal,'ar1 d turning down the opposite yend, as shown in g. 2. These clamping-jaws J J are attached to the plate C by means of set- 4 .l l A I l screws, k k, which pass through transverse slots, e e, in plate C, and are tapped into the clamping-Jaws J J.
The earsjj pass down through a largehole, which is made through `platel C, and the griping-portions jj project up eaehside of this plate C. Slots e e in the plate C, allow thejaws J J to be adjusted laterally when the set-screws cc are loosened. L is an adjusting-screw, which passes loosely through one of the ears and isV tapped into the opposite ear. This screw L isl used to adjust the plates J J, and a square head is formed on it, for receiving :they for turningthe screw. New, it will beseen that byloosening one or both of the set-screws c k, one or both of the clampingjaws or plates J J may be adjusted to any desired point, and then secured rigidly to the'plate C, by tightening the set-screw or screws r. When only one of the clamping-jaws J J is thus liberated, and thcvscrew L is turned, the looscja-n only will he moved. By this arrangement the'boot may be set exactly in the centre of the skate,A and whether the sole of the boot be very much twisted or straight, the plates or jaws J' J 4can be adjusted so as to bring the foot exactly in the centre of the skate.
The operation of securing the skate herein describedto theboot is as follows: The plates B C are brought up against the sole of the boot, and the portion E is hooked into the oye in the shank-piece D. Then the nut F is screwed up tightly, so as to draw the heel of the boot solidly against the plate B. The lip or turned-np portion, I), of the heel-plate, will non preventany longitudinal or lateral play of the skate at the heel, and the hooked portion E will keep the parts xedly in place. The setscrews k k being previously slackcned, the screw L is new tightened, and then the sot-screws k k are again tightened, so that the jaws jj are made to clamp the boot by the edges of the sole, and hold the Ysole of the boot down securely to .the plate G. Should it be found, when the skate is secured to the'boot, that the skate-iron is not in the centre of the boot, the set-screws k 7c are loosened, and the skate-iron may be moved tothe right or to the left, until it is in the centre of the hoot, when one of the screws k is tightened again, thus establishing the skate-iron in the desired position.- The plate C is covered on its top surface with a piece lof leather or'other suitable material, which is eut'out so as to tit over the transverse portions of the clamping-jaws or plates J J, which are on thetop of thel plate C, thus leaving a.
smoothsurface for thefront part of the boot to rest upon.
I do not wish to confine myself to the particular' form of the skate-iron, as the fastcnings can be readily applied to ditferentishaped irons. K f A v' Y Having thus described the invention, 'what I claimv as new, and desire to secure by Letters Patent, is as follows: l l I 1. I claim, in skates, the side clamps J J, arranged nearthe toe of the'skate, and the tightening-means L,
adapted to drawthe same` forciblytogether, all combined and arranged as and for the purposes herein set forth.
2. I claim, inskates, the set-screws c, arranged as specified,l i'n combination with the tightening-means L, andside clamps J J, so as not only to allow the side clamps to be drawn forcibly together, to seize the boot,
brut also to allow the foot to -be adjusted, either centrally upon the skate, or to any extent one side or the other, Y to suit the wearer, and be held firmly against shaking in any position, all as and for the purposes herein set forth` 3.' claim the arrangement of the shank-piece D and heel-plate B with the shank of the hoot, runner A,
and adjustable tighteninghook, E, as herein shown and described. I i y p Y PHINES SMITH.
