APPLICATION FILED APR. 12, 1913.
Patented Feb. 10, 19144' JOSEPH LAFRANCE, 0E MONTREAL, QUEBEC, CANADA.
Specification of Letters Patent.
Patented Feb. 10, 1914.
Application filed April 12, 1913. Serial No. 760,795.
To all whom it may concern Be it known that I, JOSEPH LAFRANCE, a subject of the King of Great Britain, of the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements Relating to Adjustable Boiler-Stands, and do hereby declare that the following is a full, clear, and exact description of the same.
The invention relates to an improved adjustable boiler stand and has for its object the pro-vision of a device of this character which can be adjusted to suit boilers of different sizes and further to accomplish this result in an extremely cheap and simple manner.
The invention consists essentially of a plurality of legs coupled together at a concentric point from which the upper boiler supporting ends of said legs may be swung outwardly in an arc, a single bolt being provided to lock said legs simultaneously in their adjusted positions.
In the accompanying drawings Figure 1 is a side elevation of the boiler stand according to the invention with the lower end of a boiler supported thereon. Fig. 2 is a perspective view of the joint portions broken away from the legs and uncoupled.
Like numerals denote similar parts in each figure.
Referring to the drawings, 1, 2 and 3 are the legs forming the stand, each in the shape of an arrow head, the three points 4:, 5 and 6 being jointed together as hereinafter more fully described.
The upper extremity of each leg is fashioned into a shoulder 7 on which the lower edge of the boiler sits and the lower ends of said legs may be fashioned into si1ni lar shoulders for reversing the stand or into feet as desired.
8 is a ball rigidly secured to or forming part of one casting with the leg 1 at the end of the point 4, and having an elongated vertical slot 9 therethrough.
10 is a ball cup having a vertical elongated slot 11 therethrough and rigidly secured to or forming part of one casting with the leg 2 at the point 5, the interior of said cup being fashioned to fit on top of the ball 8.
12 is a ball cup exactly similar to the cup 10, having the slot 13 through its wall and rigidly secured to or forming part of a casting with the leg 3 at the point 6, said cup being adapted to fit under and against the ball 8.
In fitting the legs together, the cup 10 is placed on top of the ball 8 and the cup 12 beneath said ball as shown in Fig. 1.
A bolt 14, having a head 15 and a thread ed opposite end, is now passed through the slots 11, 9 and 13, and a nut 16 is screwed onto the threaded end of said bolt and tightened to clamp the parts 8, 10 and 12 together. Before tightening however, the legs, each of which can be moved in a plane radial of the ball 8, are. adjusted to fit the diameter of the particular boiler which is to be supported.
If found desirable I may change the shape of the legs or add ornamentation, all of which may be accomplished without departing from the invention.
hat I claim is An adjustable boiler stand comprising three legs each extending inwardly below the upper end to a concentric point, one of said legs having a ball at the inward extension with a vertical slot therethrough, another leg having a ball cup with a vertical slot therethrough and adapted to fit under and against said ball, the other leg h. ving a similar ball cup and slot adapted to fit on top and against said ball, and a 85 clamping bolt passing through said slot and holding the legs in their adjusted positions.
Signed at the city of Montreal, in Canada. this 11th day of March, 1913.
