OLIVER M. RICE, OF BIRMINGHAM, ALABAMA.
' AUTOMOBILE DEMOUN'I'AIBLE-RIM TOOL.
Specification 'of Letters Patent.
Patented July 1921.
Application filed March 6, 1920. Serial No.'363,694.
' To aZZ whom it may concern:
Beit known that I, OLIVER M. RICE, a citizen of the United States, residing at Birmingham, in the county. of Jefferson and State of Alabama, have invented certain new and useful Improvements in Automobile Demountable-Rim Tools; and I do hereby declare the following to be a full, clear, 1 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 present invention relates to improvements in tools for contracting and expanding demountable rims, and has for an object to produce a device of this character that will be exceedingly easy to operate and exceedingly strong in construction. v
With the foregoing and other objects in view the invention consists in the constructions, combinations and arrangements hereinafter described and pointed ,out in the claims.
In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: I
Figure. 1 is a plan view of a tool constructed according to the present invention and shown applied to a fragmentary rim.
Fig. 2 is a sectional view taken on the line 2-2 in Fig. 1;
Fig. 3 is a sectional view. taken on line 3-3 in Fig. 2; and
Fig. 4 is' a transverse sectional view throu h the gear mechanism.
Reining more particularly to the drawings, 1 and 2 designate the adjacent ends of the usual demountable rim having the cross cut 3 at which the rim may be expanded or contracted in the usual manner.
The rim is perforated as indicated at 4 and 5 to receive headed pins 6 and 7 projecting from a-pair of heads 8 and 9.
The head 9 is carried on the outer end of a threaded shaft 10, which fits loosely for reciprocating movement in a bore 11 provided in a frame 12, which carries the other head 8.
As shown to advantage in Fig. 3, the frame 12 is provided with one or more longitudinally extending slots 13 adapted to receive-a pin 14 carried'on the threaded shaft 10 for preventing relative turning between the shaft 10 and frame 12, while allowing the free axial movement thereof a bevel pinion 15 is provided interiorly with spiral the threads whereby it may be received over the threaded shaft 10 and the teeth of which mesh with correspondingly formed teeth on a bevel gear wheel'16. A handle 17 is arranged inoperative relation to the gear wheel 16 for rotating the same, whereby similar movement may be communicated to the pinion 15. l
.As shown in Fig. 3, a sleeve 18forming part of the frame 12 extends against one side of the pinion 15, while the end of a housing 19 engages the opposite end ofsaid p1I11OIl 15 so that the same is fixed against longitudinal travel.
A stud 20 is formed together with the frame 12 or housing 19 and projects at right angles to the axis of .the frame and screw shaft 10, and provides a bearing on whichthe gear wheel 16 may be mounted. The gear wheel 16 and crank handle 17 are referably rotatably mounted on the stu 20, which is fixed, said handle and gear wheel being splined together. It is obvious that other arrangements, however, may be made if desired.
The housing 19 is also provided with one or more legs 21, two legs being shown in the drawings extending in opposite directions from the lower edges of the housing 19 and having outwardly projecting feet 22 for engagin the ground or a supporting surface where y the device maybe sustained at an elevation thereabove as indicated in Fig. 4.
In use, the handle 17 may be rotated in either-direction according as it is desired to expand or contract the rim' 1, 2. Rotary motion of the handle 17 is imparted to the gear wheel 16, and consequently to the pinion 15 which-is fixed in the housing 19 against axial movement.
The threads on the interior of the pinion 15 turning about in engagement with the spiral threads of the shaft 10, will cause the longitudinal or axial feeding of said shaft in the one or the other direction.
The pin 14 traveling longitudinally in the slot 13 of the frame 12, will keep both the frame and spiral shaft 10 from relativerotation, and the frame and the shaft will therefore be moved apart or together so cordingl as the 'inion 15 is driven in the one or t e other irection.
The pin 14 traveling in the slot 13 will also reserve the heads 8 and 9 in a correct position with their pins 6 and 7 projecting tions 4 and 5 in the rim. The feet 21 support the parts above the ground so that no interference ma be had with the operation of the gears an their movable parts. i
In actual use the device has been found to give excellent results, as it develops great power with the application of little energy. lit will, of course, be understood that the feet 21 may be adjustable if desired.
It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.
I claim: y
1. A tool of the character described comprising a frame having a smooth bore therein and a groove extending longitudinally with said bore, a threaded shaft slidably fitted insaid smooth bore and having a projection entering said groove to prevent relative rotation between the shaft and frame, heads carried by the outer ends of said frame and shaft, parts on said heads adapted to engage with a demountable rim, a housing extending about one portion of said frame and having an end-wall disposed close to said threaded shaft, a sleeve forming a continuation .of said frame closely embracing the threaded shaft and spaced from said end wall, a pinion having spiral interior threads engaged with the threads on said threaded shaft, said pinion disposed between the end of said sleeve and said wall, a stud projecting from said frame at right angles to said threaded shaft, a beveled gear wheel on said stud meshing with said pinion, means engageable over said stud and having connection with'said gear wheel to rotate the latter, and a pair of feet diverging in opposite directions and provided with angularly disposed toes for supporting the frame and housing, said feet being formed on said frame and housing, substantially as described.
2. A tool of the character described, comprising a frame having a smooth bore therein, a threaded shaft slidably fitted in said smooth bore, heads carried by the outer ends of said frame and shaft, parts on said heads adapted to engage with a demountable rim, a housing extending about one portion of said frame and having an end wall disposed close to said threaded shaft, a sleeve forming a continuation of said frame closely embracing the threaded shaft and spaced from said end wall, a pinion having spiral interior threads engaged with the threads on said threaded shaft, said pinion disposed between the end of said sleeve and said wall, a stud projecting from said frame, a beveled gear wheel on said stud meshing with said pinion, means engageable over said stud and having connection with said gear wheel to rotate the latter, and feet diverging in opposite directions for supporting the frame and housing, said feet being formed on said frame and housing, substantially as described.
