APPARATUS FOR REMOVING VULCANIZING BAGS; ii

Application filed February 23, 1924. Serial No. 694,519.

To all whom it may concern:

Be it known that I, GEORGE K. MCNEILL, a citizen of the United States, and a resident of Detroit, county of \Vayne, and State of Michigan. have invented a certain new and useful Apparatus for Removing Vulcanizing Bags, of which the following is a full,

\ clear, and exact description.

This invention relates to a machine for removing vulcanlzingbags from casings. It aims to provide a simple, lnexperisive, laborsaving and readily manipulated appliance gaged with one side of the casing, andmay be pulled upon to" strip the bag from within the casing. An embodiment of the invention is illustrated in the accompanying drawings, in which 4 p Figure 1 is a perspective view of the apparatus;

Figure 2 shows the first step in mounting a nested casing and bag; a

And Figure 3 illustrates the parts when the bag has been partly drawn out of the casing.

The apparatu comprises a frame, indicated generally the numeral 1, consisting of structural steel parts bolted or riveted together in any manner convenient, not requiring detailed explanation. To a crossbar 2 of the framel is secured a downwardly directed hook 3, preferably with provision for adjustment provided by the slot and bolt connections indicated at 4. This adjustment capacitates the apparatus for tires of different sizes. At opposite sides of the hook 3 are more or less upright arms or rests 5, carrying preferably. fairly broad plates 6-, afl'ording an abutment against which the casing 7 may lie and be pulled upon without scar or injury. Lengthwise and at opposite sides of the frame 1, are guide-rods 8, which are suitably secured to the cross-bars 2. These afi'ord guides for a cross-head or slidable member 9 to which at 10 is pivoted a hook 11 normally held in the raised position shown in Figure '1 by a spring 12.

bag 13 falls 11 This construction permits the hook 11 to be moved manually down past the hook 3 and between the'casing'T and the vulcanizing bags 13 nested therewithin.

While the cross-head 9, carrying the hook 11, may be actuated in any suitable manner, it is preferred to employ a pneumatietor hydraulic) cylinder .14 whose piston rod 15 is connected directly with the cross-head, the axis of the cylinder 14 being parallel with the guide-rods 8. The cylinder l t'may be secured rinmiy in any suitable manner to the frame 1. Through a foot treadle 16, a rod 17, boll-crank 18, rod 19 and crank shaft 20,

any convenient type of valve mechanism:

may be actuated to control the admission. 4

In the preferred construction, depression of the tre-adle 16 retracts the hook 11 away from the hook 3' and release of the foot treadle 16 returns the hook 11 to the starting position in proximity or adjacent the hook 3. a

In operation. the nested bag and easing arepIacedin osition with the hook 3 en gaging one of he bead portions of a, casing. This may be done conveniently by canting thetire forward somewhat, as illustrated in- Fi-gure 2 of the drawings Then, the operator manually moves the hookll from the raised position shown inFigure 1 down past the hook 3 and between the bag 13 and the casin" 7 By resting his weight upon the hook 11, the operator can insert it suflici'entlv and exhaustof fluid under pressure to and from the opposite ends of the cylinder 14.

to get a good grip on the bag 13. -While maintaining the pressure of his weight upon the hook 11, the operator then depresses the foot treadle 16 so as to supply'fluid under pressure to the proper. end of thecylinder 14 and thereby draw the hook 11 away from the hook 3. This. results in. forcibly pulling the bag and stripping it out of the casing. The n the inclined platform 21 and is deflecte to one side out of the way;

The invention is not limited to the precise. construction and arrangement described above and illustrated in the drawings, and

reference should therefore be made to the appendedelaims for afull understanding of its scope. 1 Y

Having thus described my invention, what I claim and desire to protect by Letters Patent is a 1. An apparatus for removing vulcanizing bags from casings comprising, in combination, means engageable with a bead portion of a casing at one side thereof, rests for the opposite sideof the casing, and power operable means manually engageable with a bag within the casing for pulling the two apart.

-2. An apparatus for, removing Vulcanizing bags from casings comprising, aframe, a hook fixed to the frame, arms secured to the frame on opposite sides of the hook and therewith constituting a supporting holder for an annular casing, a manually and bodily movable hook, and means for moving the latter bodily whereby a bag may be pulled out of a casing.

3. An apparatus for removing vulcanizing bags from casings comprising, a frame, a hook fixed to the frame, arms secured to the frame at opposite sides of the hook and therewith constituting a supporting holder for an annular easing, a member slidable on the frame away from said hook, a second hook movably mounted on the member for engaging a'loag in proximity to said firstmentioned hook, and means for shifting said member away from the first-mentioned hook whereby a bag may be pulled out of a casing.

4. An apparatus for removing vulcanizing bags from casings comprising, a frame,

hook fixed to the frame, arms secured rigidly at opposite sides of the hook and therewith constituting a supporting holder for an annular casing, a second hook movable transversely of the supporting holder and in a line passing in proximity to the fixed hook, said second hook bein also manually movable in a plane perpendicular to that defined by thesupporting holder for the casing, and means for moving the second hook.

5. An apparatus for removing vulcanizing bags from casings comprising, a fixed hook, a movable hook, means for shifting the movable hook away from, the fixed hook, rests at opposite sides of the fixed hook and constituting therewith a supporting holder for a casing, and a spring normally holding said second hook in an elevated position but permitting it to be manually moved into proximity with the first-mentioned hook whereby a bag may be pulled out of a casing.

6. An apparatus for removing vulcanizing bags from casings comprising, a frame, a hook fixed to the frame, arms secured to the frame at opposite sides of the hook and therewith constituting a supporting holder for an annular casing, a member slidable on the frame away from said hook, a hook on the member for engaging a bag in proximity to said first-mentioned hook, means for shifting said member away from the firstmentioned hook whereby a bag may be pulled out of a casing, and an inclined platform within the frame and below the slidable member for deflecting removed bags to a non-obstructing position.
