INVENT [1H I @AEM ATTUHNEYE CARL B. DREVITSON, OF SOMERVILLE, MASSACHUSETTS.

SKATE.

Application filed February 15, 1921.

To all whom t may concern.'

Be it known that I, CARL B. DREvrrsoN, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Skates, of which the following is a specification. 'l

This -invention relates to a skate of the type'disclosed by my Patent No. 1,115,790,

1,0 of November 3, 1914, including a runner, and a 'cast-metal foot-supporting frame united to the runner, and composed of a metal different from that of the runner, the frame being usually cast from a metallic mixture containing aluminum, while the runner is usuallyA composed of steel.

I-Ieretofore the frame has been cast in one piece. patent the frame is united with the runner by being cast directly thereon, the frame being interlocked with the runner by the casting operation. Owing to the somewhat compleX form of the frame the casting operation sometimes results in the formation of imperfect castings, involving loss ofl time,l labor and material.

The present invention has for its object to prevent liability of such loss', and is embodied in a skate, the frame of which is cast in two separate sections, united to each other and to the runner after the casting operation, the assemblage of said sections and the runner forming a skate of the same general form and appearance as that of my' former patent. l

` Of the accompanying drawings forming a part of this specication,-`

Figure 1 is a side elevation 'of a skate embodying the invention.

Figure 2 is a top plan view of the same.

Figure 3 is a section on line 3-3 of :.F i re 1.

igure 4 is a section on line 4-4 of A Fi re I.

igure 5 1s a section on line 5-'5 of Fi re 1.

i re 6 is a perspective view of one of the ame sections.

The same reference characters indicate the same parts in all of the figures.

In the drawings,- 12 represents the runner, which may be of any'desired form.

The cast-metal foot-supporting frame is composed of two independently cast sections forming, when-assembled an elongated base 13, 13, recessed to recelve the upper In the skate shown by my former Specification of Letters Patent. rPatented Feb. 7, 1922.

Serial No. 445,144.

-ate standard designated by 16, 16, a heel support, designated by 17 17a at the upper end of the rear standard, and a sole support designated by 18, 18a at the upper ends of the front and intermediate standards. The rear and intermediate standards are usually hollow and of tapering form. l

' The sectional construction of the frame is disclosed in the completed skate by a longitudinal seam or joint at the median line of the frame, as indicated by Figures 2, 3, 4 and 5. v

Each section is provided with a downwardly facing longitudinal shoulder 19 on its base portion, bearing on the upper edge of the runner, a side face 20 above j said shoulder, the side faces 2Ol of the two sections being reciprocal and abutting against each other, and lower side faces 21 below the Ashoulders 19 bearing on the opposite sides of the runner.

Each reciprocal side face 20 is extended or ramied, as best shown by Figure 6, so that it includes portions formed on the base, vthe standards and the heel and sole supports.

' -It will be seen that the form of the sections is relatively simple, so that liability of forming imperfect castings is reduced to a minimum. v

When the sections are assembled on the runner they are united to the'runner and to each other. The base sections 13, 13a are united toeach other and to the upper portion of the runner by rivets 23, and the standard sections are united to each other by rivets 24, engaged with ears 25, formed p on said sections, thel meeting faces of the,` ears being flush with the side faces 20.-

lThe bearing of the downwardly facing shoulders 19 of the base sections on the upper edge of the runner 12, prevents shear'- ing pressure on the rivets 23 and 24, by the pressure of the wearers foot on the sectional heel and sole supports. 105

I claim: y

1. A skate comprising V,a runner and a cast-metal foot-supporting `frame, composed of independent sections forming, Whenassembled, an elongated sectional base recessed to-receive the' upper ledge of the runner, spaced apart Sectional standards prol jecting upward from the' base; sectional opposite sides of therunner, rivets uniting the base sections to Athe runner, and rivets uniting .the standard 'sections to each other, the bearing foi said downwardlyT facing shoulders'on the upper edge of the runner ,preventing shearing pressure o-n said rivets.

2. A skate comprislng a runner and a cast-metal foot-supporting frame, composed of independent sections forming, when assembled, anv elongated base recessed' to receive the upper edge of the runner, spaced apart standards projecting upward from the base, and heel and sole supports at the f upper ends of said standards, said sections being provided with. downwardly 'facing longltudinally extending shoulders, lbear-i ing' on the upper edge of the runner, upper re sai side -faees abuttingv against each other and including portions formed on the base, the standards, and the heel and solev sup-` ports, and lower side faces below said shoulders lbearing on opposite sides of the' runner, the base portions of the sections being united to each other and to the runner, and the., standard portions being` provided with reciprocal ears flush with said side faces, and united to each other above the runner by rivets. l 3. A skatev substantially as specified by claim 1, the base portions of thel sections being united to each other and t0 thev runner, land the standard portions being provided with reciprocalears Hush: with said the runner by rivets.
