Patented Aug. 12, 1930 PATENT OFFICE WILLIAM A. THOMPSON, OF NORTHLAND MINES, ONTARIO, CANADA INTEBCHANGEABLE SKATE Application filed May 27,

This invention relates to the class of skates, and more particularly relates to tubularice skates.

The principal object of the invention is the production of a combination of parts well suited for economical manufacture, which may be utilized to produce a skate suitable for racing, a skate suitable for pleasure skating or for hockey, and a skate suitable for figure or fancy skating.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which- Figure 1 is a side View of a racing form of skate constructed in accordance with the invention, ortions being broken away to show certain structural features.

Fig. 2 is a side view of the heel plate and connected plug.

Fig. 3 is a side view of the sole plate and connected plugs.

Fig. 4 is a side view of the runner structure and connected sockets.

Fig. 5 is a section taken on the line 5-5 of Fig. 1.

It is to be understood that the invention contemplates a combination of parts which will include runners of different forms namely a runner for racing, a runner for pleasure skating or for hockey, and a runner for figure or fancy skating. Each runner is secured to a main part of tubiform having attaching 3 hoses. The runner and tubiform part will constitute a unitary structure adapted for application thereto of other parts to be hereinafter described to constitute a skate of one of the forms mentioned.

Referring now more particularly to the drawing, it will be apparent that there has been shown a main tubiform part 10 having depending flanges 11 embracing and secured to a runner. As shown in Fig. 1, the runner 12 is suitable for racing, whereas the runner 13 shown in Fig. 4, is suitable for figure or fancy skating. Obviously other forms of runners may be provided which will be suitable for pleasure skating or suitable for hockey. The tubiform part 10 has secured 1929. Serial No. 366,437.

or brazed thereto bosses 14, 15 and 16 of desired shapes and proportions. Each boss has a threaded hole 17. Use is made of hollow parts or sockets 18, 19 and 20 of the desired shapes and proportions. Use is also made of hollow parts or plugs 21, 22 and 23 adapted for association respectively with the parts 18, 19 and 20.

The parts 18 and 19 are identical, each being, in the form of a truncated cone having a lower integral end wall 24 with a hole 25 therein. The part 20 is cylindrical and also has an end wall and hole like the parts 18 and 19. The parts 18, 19 and 20 are adapted to be detachably secured respectively to the bosses 14, 15 and 16 by headed screws 26. Each screw 26 is projected through the hole 25 in the related part and is screwed into the threaded hole 17 in the related boss, the head of the screw being brought into engagement with the end wall 24. v

The parts 21 and 22 are identical, each be ing in the form of an open ended-truncated cone. The part 21 is secured in any suitable manner to a shoe or boot attaching plate 27, the same being the heel plate, whereas the part 22 is secured in any suitable manner to a shoe or boot attaching plate 28, the same being the sole plate. The part 23 is cylindrical to conform to the part 20, and said part 23 is open at each end. The part 20 is secured to the sole plate 28 in any suitable manner.

In order to detachably and turnably conneet each of the parts 21, 22 and 23, individually with the related parts 18, 19 and 20, each of the parts 21, 22 and 23 and said parts 18, 19 and 20 has coacting means in the form of threads 29 on the said parts-18, 19 and 20 and threads 30 on the parts 21, 22 and 23. It will therefore be understood that the part 18 is adapted for threading engagement with the part 21, the part 19 is adapted for threading engagement with the part 22, and the part 20 is adapted for threading engagement with the part 23.

To assemble the parts of a skate the parts 18, 19 and 20 are connected with the parts 21, 22 and 23; after which the screws 26 are driven home to connect the parts 18, 19 and 20 respectively with the bosses M, 15 and 16. In this manner the heel and sole plates are detachably connected With the desired runner to constitute a skate of the desired form.

I claim:

1. A skate having the combination of a runner member, a boss integral With said runner member and having a threaded hole, a socket, a screw engageable with the lower end of the socket and adapted for threading engagement in said hole to detachably secure said socket to said boss, a hoot or shoe attaching plate having a hollow plug, and coacting means on the socket and plug to detachahly secure them together.

' 2. A skate having the combination of a runner member, a socket, a fastening element to detachably secure said socket to said runner member, a boot or shoe attaching plate having a hollow plug, and coacting means on the socket and plug todetachably and turnahly secure them together.

3. A skate having the combination of a runner member, a socket, a fastening element to detachahly secure said socket to said runner member, a boot or shoe attaching plate having a hollow plug, and coacting threads on the socket and plug to detachably secure them together.

4. A skaw having the combination of a runnerv member, a cone-shaped socket, a {as tening element to detachably secure said socket to said runner, a boot or shoe attaching plate having a hollow cone-shaped plug, and coacting means on the socket and plug to detachably secure them together.

5. A skate having the combination of a runner member, sockets, fastening elements to detachably secure said sockets to said runner member, hollow open-ended plugs, there being one plug for each socket, coacting means on each socket and its plug to detachabl secure them together, and means car.- rie by the plugs for securing the skate to a boot or shoe.
