To all whom it may concern:

Be it known that I, FRANK FnAsEn JAMInsoN, a subject of the King of Great Britain, a resident of'Montreal, in the Province of Quebec and Dominion of Canada, have invented a certain new and useful Improvement in a Stripping Device,

of which the following is a full, clear,

and exact description. I

This inventionrelates toa stripping de-' vice, more particularly to a device for stripping vulcanized articles from the cores on which they are formed. 7

In the making of many ticle over the point of greatest diameter of,

stretch required in this operationis con siderable, beingfrequently over 500%: If

' such articles are made of a stock which is 5 move them from the core.

not sufficiently elastic and toughthey' will be torn and damaged in attempting to rehand, ifa tough and good quality stock is used the stretch required is'too great for the strength of the average workman, and in the struggle to remove the bag the latter in frequently damaged by the hooks and must be scrapped.

An objectof my invention is toprovide' V ation.

For a detailed disclosure of the invention,

reference is had to the accompanying specification and drawing, in which latter:

Fig. 1 is a front tion; and

vulcanized ar tlcles such as hot water bottles, syringe bags, f

1 represents a table or: other support upon which the device may ,bemounted, and secured to, this in any suitable manneris an upr1ght'2 carrying at its top a pulley 3 over whlch' 1s movablea chain A. To the rear end of the chain one end of'a. link Sis con A ooRroRArIoN or Referring to the drawing, the numeral nected, the other end of which -ijs pivotally connected to the foot lever 6, the latter have i ing a return spring 7'. The other end of] i the chain 42 carries a hook 8, and the pro jectlng portion 9 of a core maybe secured to this hook by means of an opening in the surrounding flange 10.

p The projecting. portion 9 of the core is iverticallymovable: in a guideway 11 secured tothesupport 2,

and the sides of the guideway-prevent. lateral movement of the core. "Secured to the upright 2 is a cross-bar 12, vto the" ends of "which levers 13 are pivotally Se cured at 14. Also mounted on the pivots "1a and secured ,to the respective levers 18 are operating earns 15' each of which has a curved side 16 which is provided i to. each cam adjacent one end of the groove 17 and in alignment with the groove,

with the longitudinal groove 17. Secu'red is a chain 18, the other end of which is connected toa stripping hook 19 intheman- Each hook on its ner shown in 'Fig. 1. outer side 1s provlded with a groove 20 adapted to interfit with the rounded edge of h the core used. A second chain 21 is also a secured to the cam 15 at one end and at the-1v I other end to the free or 'shanl'r end of the hook. Cooperating with each cam 15 is a stop pin'22 movable through the cross-' bar 12. I a

In operation, the core 9' and its surround-' ing water bottle 23' after removal from the mold are hung upon the hookS and the, stripping hooks 19 are inserted between the 4 core neck' and bottle neck in the manner shown on the right-hand Side of Fig.1

with the groove, 20 of each hook engaging? One of the operating level-s13 is then moved the inclined upper edge of the core.

As the lever 13 moves outwardly the, hook 19 moves laterally and downwardly on the
