LEATHER MOLDING MACHINE.
APPLICATION IILED JUNE 24. 1912.
1,064,159, Patented June 10,1913.
Swwentoo UNITED TATE PATEN QFFICE,
DON O. NATION, OF OKLAHOMA, OKLAHOMA.
LEATHER-MOLDING MACHINE.
To all whom it may concern:
Be it known that I, DON O. NATION, a citizen of the United States, residing at ()klahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Leather- Molding Machines, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to new and useful improvements in molding machines and more particularly to a leather molding machine and the primary object of the invention is to provide a device of this character which will efliciently mold leather for pneumatic tire casings such as shown in my pending application, filed May 16th, 1912, Serial Number 697 ,71 1, or for molding leather faces for cone clutches used on a number of automobiles.
A further object of the invention resides in providing a machine having a pair of rolls between which the leather is adapted to be disposed, one of said rolls being stationary and the other movable to correspond with the base and core member of an ordinary mold.
A further object of the invention resides in providing resilient means for normally retaining the movable roll in its effective position against the stationary mold and a further object resides in the provision of means for the manual disposition of said movable mold to its ineffective position.
Still another object of the invention resides in providing a device which is extremely simple and durable in construction, inexpensive to manufacture and one whlch will be most eflicient and useful in operation. 1
With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.
In the accompanying drawing forming a part of this application, Figure 1 1s a side elevation of my device set up for use. Fig. 2 is a top plan view thereof; and F 3 is a side elevation of a slightly modified form of the device showing a pair of rolls adapted to be substituted for the rolls shown in Fig. 1.
Specification of Letters Patent.
Application filed June 24, 1912.
In describing my invention, I shall refer atented J une 10, 1913. Serial No. 705,611.
to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which- 1 indicates a supporting base or standard, the upper portion of which has formed thereon a frame-like portion comprising a horizontal base 2 and a pair of spaced vertical arms 3 and 41-. Rotatably mounted on a vertical axis in the one end of the base or horizontal portion 2, is a convcxed roll 5, the upper portion of which terminates in a bevel gear 6 and formed on the roll intermediate of the convexed portion thereof and said gear 6, is a flattened portion 7, providing a substantial shoulder thereon.
Extending horizontally of the arms 3 and 4t, and rotatably mounted therein is a shaft 8, the one end of which has mounted thereon the concave roll 9, the curvature of which is designed coincident to the outline of the convexed roll 5, and formed adjacent the axial center of said roll 9, is an additional bevel gear 10 adapted for engagement with the gear (5 of the aforesaid roll 5. This roll 9 is also provided with a flat portion 11 intermediate the gear and the concave portion thereof, which flat portion also forms a substantial shoulder and is adapted to rest against the flat portion or shoulder 7 of the roll 5 and in order to retain said roll 9 in normal contact with the roll 5, said shaft 8 has mounted thereon a collar 12 which is disposed intermediate of the arms 3 and t, while a coil spring 13 is encircled about said shaft between said collar 12 and the arm 1. This spring 13, it will be seen, has a normal tendency to force the shaft 8 in a direction toward the roll 5, thereby forcing the roll 9 into engagement with said roll 5 and correspondingly engaging the two gears (i and 10 and carried on the opposite end of the shaft 8 is a crank or handle member 1 1 which may be manually operated to cause the shaft and rolls to be rotated. Strips of leather are adapted to be inserted bet-ween the rolls and as said shaft 8 is rotated, the rolls will form the strips of leather in a design corresponding to the outline of the eonvexed and concave rolls, the leather being simultaneously fed therefrom. From the showing made in the drawing, it will be seen that the leather will be designed arcuate for a greater portion of its width, the one edge thereof being flattened through the medium of the flattened portions 7 and 11 of the rolls is engaged the collar 12.
5 and 9 respectively, which design will correspond to the leather sections forming the tire casing in my pending application, filed May 16th, 1.912, Serial Number 697,714.
In order to properly insert the strips of leather between the rolls prior to setting the machine in operation, I provide a means for withdrawing the roll 9 from its normal effective position. To this end, I provide a lever or the like 15 which is pivoted at its upper end to ears 16 carried on the upper portion of the arm 3, said lever being provided with a circular portion 17 through which the shaft 8 extends and with which This lever normally receives the collar 12 thereagainst to limit the movement of the shaft 8, as shown in Fig. 1, and the lower free end of said lever 15, which in its normal position contacts with the lower portion of the arm 3, has engaged therewith a flexible connection 18, which extends over the pulleys 19 and is connected with a pivoted foot-lever 20 at the lower portion of the base or standard 1. lVhen pressure is placed upon the free end of the foot lever 20, it will be seen that the lever 15 will be swung on its pivot to withdraw the shaft 8, thereby drawing the roll 9 from the stationary roll 5 and disengaging the gear portions 6 and 10 which will allow the leather to be inserted or removed as desired. The disposition of this roll 9 to its ineffective position, may also be desired for the purpose of removing the rolls shown in Fig. l in order to substitute the rolls shown in Fig. 3. In this latter figure, I have shown a pair of rolls 21 and 22, which are both of frusto-conical design, the former being adapted to be mounted on the portion 2 similar to the roll 5, while the latter is adapted to be mounted on the shaft 8, similar to the roll 9. These two rolls have the outer faces at the axial centers thereof provided with gear portions 23 and 24: respectively which are adapted to normally intermesh and the roll 21 is provided intermediate of its gear portion and its conical face, with a shoulder 25 which is adapted to receive thereon a flange or rib 26 formed on the roll 22 intermediate the gear portion and frusto-conical face thereof. These rolls, when properly applied to the machine in substitution for the rolls 5 and 9, are adapted to receive a flat leather strip therebetween and when the machine is properly operated, the leather strip will form a longitudinally arcuate strip from a flat straight strip, the re sulting arcuate strip being particularly adapted for use as a face for a cone or clutch used on automobiles.
From the foregoing description of the construction of my device, the operation thereof will be readily understood and it will be seen that I have provided an improved leather molding machine which is simple and durable in construction, inex pensive to manufacture and one which will be very efficient and useful in operation.
While I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the in vention.
Having thus described this invention, what I claim is 1. A leather molding machine comprising a supporting member, a roll rotatably mounted on a vertical axis thereon, a horizontal shaft rotatably and slidably mounted 011 said supporting member, an additional roll carried on one end of said shaft, bevel gears formed on the outer faces of said rolls, 5 means for normally retaining the last mentioned roll in yielding contact with the first mentioned roll to correspondingly retain said gears in mesh with one another, means for rotating said shaft, and means for slide0 ing said shaft to correspondingly disengage the rolls.
