CLAMP-FASTENING DEVICE FOR SKATES.

SPECIFICATION forming part of Letters Patent No. 618,321, dated January 24, 1899.

Application filed October 13, 1898. Serial No. 693,403. (No model.)

To aZZ whom it may concern:

Be it known that I, EVERETT II. BARNEY, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts,have invented new and useful Improvements in Clamp-Fastening Devices for Skates, of which the following is a. specification.

This invention relates to skates, the object being to provide improved devices for adj ustably connecting the sole and heel clamps thereof, whereby the clamp-bar extending between and unitingsaid clamps is screw-connected by one end with either the one or the other of the latter for clamp adjustment by turning said bar, and a bar connection for the other clamp parts is provided, containing means for both locking said bar frictionally against rotary movement and for preventing endwise movement of said bar therein, but when required permitting the same to be rotated for adj usting the clamps to a shoe; and the invention consists in the peculiar construction and arrangement of the said soleclamp connection which receives one end of said rod, and means structurally present in said connection and cooperating therewith for preventing endwise movement 0 if said rod and for locking the latter against rotary movement, all as hereinafter fully set forth, and more particularly pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a bottom plan view showing the runner partly broken away, and Fig. 2 is a side elevation of a skate provided with sole and heel clamp connections embodying my invention. Fig. 3 is a plan view of the rear end of the sole-plate of the skate, of the sole-clamp connection therein, and a portion of the connecting-rod which unites the sole and heel clamps of the skate. Fig. iis alongitudinal section of certain parts shown in Fig. 3 on line at at thereon and a side elevation. of the end of the said connecting-rod which is connected with said sole-clamps. Fig. 5 is a sectional view on line 5 5, Fig. 3, and includes a side elevation of the rod-locking screw shown in connection with the parts illustrated in Figs. 4: and 5.

Referring to the drawings, A indicates the runner; 13-, the sole-plate; C, the heel-plate, having a heel-abutment a; thereon; D, the

sole-clamp5 E, the heel-clamp, and F the clamp-operating lever of the skate pivoted on said heel-clamp, said several parts constituting well-known structural elements of skates of the class shown.

The novel construction of said sole-clamp connection and of the clamp-rod which unites said sole and heel clamps and other parts cooperating with the above, whereby the results set forth in the foregoing statement of invention are obtained, is as follows:

The said sole-clamp connection consists of a stud h, having a cylindrical body, as shown; a head 3, preferably of outwardly-convex form; a transverse perforation 4: through said body, in which is received one end of said clamp-rod, a second transverse perforation 5 at right angles to said perforation 4 and in tersecting the lower side of the latter, as shown, and a longitudinal perforation 6 extending through the head 3 and inwardly to and communicating with the upper side of said perforation 4. The body of said stud it passes through a slot in said sole-plate B and through the rear ends of the sole-clamps D, said stud being adapted for movement longitudinally in said slot when said clamps are moved to carry their outer extremities toward or away from the border of the shoe to which the skate maybe applied. A clamprod-locking screw 7 screws into the said perforation 6 extending through the head 3 of said stud, said screw having a fiat-faced eX- .tremity on its end opposite said head or, in

other words, an extremity whose face is at right angles to the axis of the screw, and said screw when in operative position against the clamp-rod, as hereinafter described and as shown in Figs. at and 5, has its head brought slightly below the surface of the headB of said stud h. The aforesaid clamp-rod is indicated by 8, and has a concentric groove 9 formed therein near one end, as clearly shown in Fig. 4, and after placing the end of said rod, in which is said groove, into the said transverse perforation 4c of the stud h a pin 10 is driven through the said transverse perfora tion 5 in said stud under said clamp-rod 8 and has the side thereof within said stud engaging in said concentric groove 9, whereby the said clamp-rod may be rotated within said stud, but prevented from any longitudinal movement therein. After said clamprod shall have been so entered. into said stud it is there locked rigidly against any rotary movement by said locking-screw 7, the said flat inner end of said screw bearing frictionally upon the surface of said rod beyond the borders of said groove 9, and as the head of said screw is below the surface of the head of said stud it is guarded against being inadvertently disturbed or moved from the position which it is shown to occupy in Figs. 4 and 5, this last-named figure being a sectional view of that part of said clamp-rod 8 directly beneath the inner end of said locking-screw '7, and both Figs. 4 and 5 illustrate clearly the engagement of said pin with the concentric groove 9 formed in the said clamprod. The opposite end of the clamp-rod 8 to that which is engaged by said stud it has a screw-threaded connection with the stud 12, which is pivotally connected to the clampoperating lever F, as shown in Figs. 1 and 2, and intermediate of the extremities of said clamp-rod the latter has its surface knurled to provide for conveniently grasping the same with the fingers to rotate it, thereby increasing or diminishing the distance between the studs h and 12, whereby the said sole-clamp and heel-clamps of the skate are so adjusted that by swinging said clamppperating lever F in one direction the clamps are brought to bear upon the sole and heel of the shoe, and by swinging the same in the opposite direction they are released therefrom.

The manner of operating the before-mentioned improvements is as follows: Assuming that it be desirable for the purpose of adjusting a skate to a shoe to change the relative positions of the studs h and 12, (shown in Fig. 2,) whereby they shall be more separated or brought nearer to each other, the said locking-screw 7 is first turned back to draw its inner end out of said frictional engagement with the surface of the clamp-rod 8. Said rod is then turned by applying the finger and thumb to the said knurled portion thereof, and since the end of said rod which is held in said stud It cannot slide therein because of the engagement of the said pin 10 there- -with, as described, the said stud 12 and the erations ordinarily take place after placing the skate against the sole and heel of a shoe, and by operating said clamp-rod,as described, and the clamp-lever F the proper adjustment is soon attained. After said adjustment shall be found to be satisfactory the said lockingscrew 7 is again screwed tightly against said clam p-rod and the parts are thereby held permanently in adjustment. It will be noted that in the construction herein shown and described the means for preventing any separating or approaching movement of said two studs h and 12 consists of said rotatable clamprod screw connected with one of said studs 12, and that the means for holding said rod against endwise movement in said stud h and for locking said rod against rotary movement are both embodied in said last-named stud and comprise the said pin 10 and screw '7, acting in the manner described to hold and to lock said rod, thus embodying said means for controlling the action of said rod wholly in one of said two studs. Thus the construction herein shown for effecting the last-named objects is simplified and rendered compact, so that the operations for said adjustments are more conveniently and surely effected.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In'skate-fasteningdevices, two pivot studs connected with the sole and heel clamps of the skate respectively, a clamp-rod extending between said studs having one end screwengaged with the body of one of said studs transversely of the axis thereof and having its opposite end entering a transverse perforation in the second of said studs, combined with means .in said last-nan1ed stud engaging and holding said rod against endwise movement therein, and means within the same stud for locking said rod against rotary movement, substantially as described.

2. In skate fastening devices, two pivotstnds connected with the sole and heel clamps of the skate respectively, a clamp-rod extending between said studs having one end screwengaged with the body of one of said studs transversely of the axis thereof and having its opposite end grooved and entering a transverse perforation in the second of said studs, combined with means in said last-named stud engaging said groove and holding said rod against endwise movement therein, and a screw axially located in said last-named stud, engaging the surface of said rod, whereby the latter is locked against rotary movement, substantially as described.

EVERETT H. BARNEY.
