DEVICE FOR msnnrmo BAGS.

plp imannn center 6, 1924, se iaiit fiMeSa Y My invention relates to the manufacture of pneumatic tire casings and more particu larly to devices'for inserting; expansible cores usually referred to'ras bags in the raw casings preparatory to vulcanization. V l It is .anobject of my invention to provide a device of the character stated which: shall be positive in action and perform its'operation expeditiously and with a minimumof wear,

on the bag; Other objects will appear from the following specification and claims.

i In the accompanying" drawings which illustrate one embodiment of my invention Figure 1 is a side elevatiomand Figure 2 is a View in the direction of the arrow in Figure 1. I

secured two

upright channel members

2 and 3 by means of angle irons and 5. Ifhe;

channel members

flangesoi channel members

2 and 3. A D111 22 is rig1d- I secured to carriage 20 and extends outward ly' between the flanges of the channels A Y transverse uideway 23 is formed in the carriage, below and parallel topin 22,1n which pin 24 1s mounted for longitudinal A piston rod12 provided with head 13' pipes 14 and 1 5 connected to athree-way valve 16 (operated b'yhandle movement.

Spring'sg48 andi49 normally maintain ar -S 41 and 42 against the lower heads of the 'bo'l'tsloutper} mit the armsto swing up'ward'ly asilat'er described.

the

channels

2 and 3 and the carriage 20 are Secured between relatively fixed points two toggle s generally .indicated at 50 in Figure 2. These tog'f les each comprise

double arms

51 and 52 secured to a shaft 53 supported in b'earings'54secured to channels 2. and 3 at 55, and double arms 56' and 57 securedtd shafts 58 supported in bearing:s 5'9 formed'integral with carriageQO (seeFigIn-e 1) two' sets of arms aren'ivotally connected by pins 61 and the arms comprising eaclrset are maintained inspac'ed relation by

bearings

54 and 59 and by spacingsleeves 60'which surround pins 61. Pins 61 are extended" at 62 to formsupports for groovedrollers 63; v

Slidably mounted between the forward flanges of channels 2 and'3is a bracket 64 pro: vifd'ed at its free end with a bag seat'65. The bracl fet 54 is vertically adjustable through rod .66 rotatably secured to the bracket and threaded through lug 67, formed Y in cross-piece 618 secured between the upper ends of channels 2 and 4' by bolts 70.

a The operation of the device is as follows:

I With the parts in'the position shown in Figure 2a bag 75 is positioned on member 6 5?- with rolls63 and pin 22 engagingthe inner periphery of the bag and pin 24 engaging the outer periphery; as shown in dotted line in said figure. "Air isnow admitted'to thelower end of cylinder 7, thus raising carriage 20, carrying

pins

22 and 24, and moving rolls 63 outwardly as shown in Figure 7; Upon con-- tinued upward movement, pin 24 folds the bag about rolls 63, the latter moving inwardly to the. position shown in Figure 8. As the carriage reaches the upper end of its travel 7 lugs 32 engage pivoted arms 41 and 42 which yield against springs 48 and 49 to let the lugs pass as shown in Figure 5. A raw tire casing 80 is now positioned over the folded bag as shown in Figure 9 and air pressure admitted to the upper end of cylinder 7 to move carriage 20 downwardly. As the carriage descends rolls 63 again move outwardly forcing the side portions of the bag into'the casing. On the downward movement of the carriage lugs 32 engage flanges 43 and 44 of arms 41 and 42 thus withdrawing pin 24 as shown in Figure 6. v V s The bag being of resilient material tends to return'to its normal shape when the restraint of pin 24 and rolls. 63 are removed, and in returning to normal shape it tends to enter the casing, this tendency aiding rolls 63 in forcing the bag intothe sides of the casing as above described. Pin 22 acts to positively force the last portion of the bag into POSItlOIL, wlth the bag enclosed is now re- The casing moved. a 7

As the carriage 20 approaches its lowest positionlugs 32 strike the lower inturned portions of

cams

34 and 36 thus returning pin 24 totits original position. It will be obvious that the initial position and subsequent movement of rolls 63 may bevvaried by shortening or lengthening the members of toggles 50, as

to accommodate a different size or character of bag. 7 v Having described an illustrative embodiment of my invention, I claim:
