Specification of Letters Patent.
PatentedSept. 21, 1915.
Application filed June 11, 1915. .Serial No. 33,620.
To all whom it may concern:
Be it known that I, LEWIS VJILEY BARKER, a subject of the King of Great Britain, and residing at No. 96 Carleton street, Fredericton, Province of New Brunswick, Canada, have invented certain new and useful Tmprovements in Skate-Clamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention to be hereinafter described relates to skate clamps.
In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.
Throughout the several figures of the drawings like reference characters designate the same parts.
In the drawings: Figure 1. is a top plan view of the clamp; Fig. 2 is a front view of the same with one of the front bracket arms broken away; Fig. 3 is an end view of the clamp in use; and Fig. 4 is a section on line 44 of Fig. 2 looking in the direction of the arrows.
The main objects of the invention are to provide a compact and etlicient (lamp for holding skates for sharpening and like purposes of simple construction and operation which can be produced at a relatively low cost and can be readily and. easily moved about as required.
Referring to the drawings in detail, the base plate 1 is provided, near each end, with a transverse strip 2 riveted thereto and provided, in its under face and near each end thereof, witha recess about and concentric with a recess l in the plate 1 through the bottom of which is a circular opening having a suitable beveled edge. These recesses form ball cages or chambers in each of which is mounted a suitable ball bearing 3 of suflicient size to project slightly beyond the under face of plate 1. This provides a ball bearing mounting for the plate so that it can be readily and easily moved about on the table of the grinding machine.
An upper'plate 4 is mounted above plate 1 and is hingedly connected thereto, at its back edge, by means of a pin 5 passed through lugs 6 carried thereby and in alinement with lugs 7 integral with plate 1. A
thumb screw 8 is threaded through plate 1, at the center of the front thereof, and has its lower end secured by a loose nut in plate 1. By turning the thumb screw the front of plate 4 can be raised or lowered so as to vary its inclination as desired.
Near the front of plate 4, .at each end thereof, there is secured a transverse U shaped bracket 9 the outer or front arm 9 of which is extended and is secured, at its upper end, to the lower clamp bar 10. A second clamp bar 11 is mounted above bar 10 and the two bars are bored and threaded at their ends to receive the thumb screws 12, the upper one being recessed at each end to receive a check nut 13 threaded on to the shank of the screw. By placing the skate blade between these two bars and turning the thumb screws 12 down the blade will be firmly gripped and secured in position for grinding.
The inner arm 9 of each bracket 9 is bored and threaded to receive a thumb screw 14 the shank of which passes through a slOt in the stem of a T bracket 15 which is slidably mounted on the arm 9* and provided with lateral flanges inclosing the same for guiding purposes. A look nut 16 is threaded on the shank of screw 14, beyond the stem of T bracket 15 so that, by turning the thumb screw, the bracket may be firmly secured in vertical adjustment. Each of the brackets 15 carries a horizontal supporting plate 17 adapted to support the clearing plate or base of the skate, or the shoe if the skate be attached to a shoe. This effectually prevents any injury to the skate from strain during the sharpening operation. The supporting plates 17, due to their vertical adjustability, can be regulated to suit practically any type or size of skate, as will be evident. Also the inclination of the skate blade to be sharpened can be accurately adjusted by means of screw 8 thus insuring a proper and true sharpening.
In using my clamp the skate is secured in position and properly adjusted, and the clamp is moved along the table of the grinding machine, on the ball bearings 3, so as to bring the edge of the blade into engagement with the cutting face of an emery wheel, or other suitable grinding means, as in Fig. 3.
It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.
Changes may be made in the construction,
arrangement, and disposition of the several Within this application wherein only a pre-' ferred form has been disclosed.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a device of the character described, a base plate, a plate carried thereby and adapted to have its inclination varied, means for varying the inclination of the said plate, clamping means carried by the second mentioned plate, vertically adjustable supporting plates mounted in back of the said clamping means, and means for securing the said supporting plates in adjustment.
2. In a device of the character described, a base plate, a plate mounted above the base plate and hingedly connected thereto at its back edge, means for raising or lowering j the front of the second mentioned plate, U
brackets carried by the said second plate and having their outer arms extended,
clamping means carried by the extended outer arms of the said brackets, brackets slidably mounted on the shorter arms of the said U brackets and adapted to be adjusted vertically, supporting plates carried by the said T brackets, and means for securing the said Tbrackets in vertical adjustment.
f 3. In a device of the character described,
abase plate, ball bearings mounted in said base plate andprojecting beyond the lower 7 face thereof, a plate mounted above the base plate and hingedly connected thereto at its back edge, means for raising'or lowering the front of the second mentioned plate, .U brackets carriedby the said second plate and having their outer arms extended,-
clamping means carried by the extended my hand in the presence of two witnesses.
