APPARATUS FOR PULLING PLIES OR THE LIKE.
Specification of Letters Patent. Patented Mar. 22, 1921.
Application filed April 28, 1919. Serial No. 293,273.
To all whom it may concern:
Be it known that we, JAMES A. PURvIs and HERBERT A. SESSIONS, citizens of the United States, and residents of Traverse City, in the county of Grand Traverse and State of Michi an, have invented certain new and useful mprovements in Apparatus for Pulling Plies or the like, of which the following is a specification.
Our invention is an improvement in apparatus for pulling 'plies or the like, and has for its object to. rovide a machine of the character specifie especially designedfor pulling plies of fabric from old pneu-.
section of the I tion, and in this frame there is arran ed a wheel or drum 2, said wheel or drum eing secured to a shaft 3.
The ends of the shaft 3 are journaled in hooks l in the arms 5 of a yoke consisting of the said arms and a body 6. This yoke is connected to the end of the frame by a chain 7, one end of the chain engaging the body of the yoke, which is V-shaped as shown, 35
and the other is engaged with a bracket 8 on the frame. a
The bracket consists of a plate which is secured to the frame at the center of one end, and two upstanding lugs on the plate, said lugs being spaced apart far enough to receive a link of the chain, when the plane of the link .is vertical. Thus the drum and the shaft may be adjusted longitudinally of i and it is obvious that when the crank shaft is rotated, the drum 9 will also .be rotated,
but in the-opposite direction to the rotation of the crank shaft.
The drum has on its periphery a longitu- I dinally extending-slot 17, and this slot is adapted to receive a holding bar 18 pivoted on one end to an arm 19 extending radially from the shaft 10, and having at the other a bearing for enga ing a reduced threaded stem 20 .on a radial arm 21 at the opposite end of the drum. A nut 22 engages the stem to prevent displacement of the bar.
In operation, the oldtire from which it is desired to remove a reater or-less number of fabric plies, has rst the bead strip removed, after which the tire is placed on the wheel or drum 2, in the manner shown in Fig. 1 started in any suitable or desired manner.
The ends of these plies are then engaged within the groove 17, and are locked in the groove by the locking bar. When now the drum 9 is turned by means of the crank, it will be obvious that the plies will be wound upon the said drum, and will be stripped As the plies are stripped the tire which acts as a belt will rotate the wheel '2, in the opposite direction to the rotation of the drum 9.
As is known, reliners thus obtained are preferable, since in themakmg of the tire,
the .fabric is vulcanized under great pressure, and will .not separate. In the usual reliners the fabric is merely cemented. Stripping the tires manually is a slow, difficult and costly process. 'Wlth the improved machine a tire may be stripped in a very short space of time and with but little labor. By means of the chain 7 the holding drum 2 may be moved toward and from the stripping drum, to provide for tires ofdilferent diameter. Referring to Fig; 3 it will be noticed that the spiders 11 and the radial arms 19Jand 21 are keyed to the shaft 10.
We claim:
1. A machine of the character specified, comprising a supporting frame, a drum journaled thereon and having a longitudinally extending groove in its periphery, a locking bar for engaging the groove to clamp the fabric material therein, means for rotating the drum, and means for supporting the tire to be stripped during the stripping, said supporting means comprising a drum for engagement by the tire, and means for supporting the drum for rotation on the and the desired number of plies is from the tire, which is held by the wheel 2.
frame, said supporting means being adjust- 2; A machine of the character specified, comprising a supporting frame, a drum journaled thereon and having a longitudinally extending groove in its periphery, a locking bar for engaging the groove to clamp the fabric material therein, means for rotating the drum, and means for supporting the tire to be stripped during the stripping, said supportim means comprising a drum for engagement by the tire, and means for supporting the drum for rotation on the frame.
3. A machine of the character specified, comprising a supporting frame, a drum journaled thereon and having a longitudinally extending groove in its periphery, a locking bar for engaging the groove to clamp the fabric material therein, means for rotating the drum, and means for supporting the tire to be stripped during the stripping, the looking bar having a pivotal connection'at one end with the drum, and a detachable connection at the other end.
4. A machine of the character specified, comprising a supporting frame, a drum 'jour-- naled thereon and having a longitudinally extending groove in its periphery, a locking bar for engaging the groove to clamp the fabric material therein, means for rotating the drum, and means for supporting the tire to be stripped during the stripping.
5. A machine of the character described comprising a frame, means for engaging plies of the tire and pulling the same thererom, a rotatable drum for supporting the tire during the pulling operation, and means for varying the position of the drum to accommodate various size tires including a yoke having side arms slidably arranged on said frame said arms being provided with hooked ends constituting journals for said drum, a chain having one end connected to said yoke, and means fixed to the frame and selectively engageable with the links of the chain, as and for the purpose set forth.
