YCOLIIIARICRIMPIING AND TURNING MACHINE.

App1ication filed May 5, 1921. Serial No. 467,120.

To all whom it may concern: I

Be it known that I, JOHN IV. Hnss, of the city of Kitchener, in the county of Waterloo, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in things, to devise improved means for heatfolder plates in advanced- 'ing thefolders andfor slidably supporting the same, and to provide improved means for actuating the folder plates, to provide efficient means for-applying pressure to the infolded edges of the material.

I attain my objects by means of the constructions hereinafter described and illustrated in the accompanying drawings,-in'

which I F ig. 1 1s a plan view of a machine constructed in accordance with my invention;

Fig. 2- an end elevation of the same, partly in section;

r Fig; 3 a similar view to'fig. 2 with the position and coacting with t'he 'former;

Fig.- 4' a plan View of one of the pressure arms; i i

Fig. 5 a sideelevation of the same; and

Fig. 6 an enlarged cross section of one of the former plates; 1 In the drawings like numerals of reference indicate corresponding parts in the different figures. Y

l represents a portion of the frame of the machine in which is supported the bed 2.

3 aredoublearms 'fulcrumed atone side of the bed'and -carrying the two halves of the form 4 about whichthe edges of the material operated on are folded. The form,-

it will be noted, is formed in halves with skived overlapping edges so that the parts of the forms may be slid endwise overone an other. Each half of the form, it will be noted, is connected to one of the double arms and'these arms are slidable lengthwise of the bed on the shaft 5 journalled on the frame. When the machine is in operation these arms are suitably rocked to raise and lower the. forms and at the proper time are slid lengthwise 011 the shaft, but with these features of construction the present invention is not concerned, and apparatus for this purpose is not shown or described.

The form a is adapted to rest on the center part of the bed and with it co-operates four folder plates 6 constructed as hereinafter described. These folder plates are adapted to be moved diagonally inwards towards the center of the bed and therefore to close about the form, at. The plates rest on two bars 7 which extend lengthwise of the bed, their upper surfaces being slightly above the level of the portion of the bed against which the form 4 rests when in its lowered position.

The preferred arrangement of these bars is to form a projecting rib 8 at each edge of the bar, which is received in grooves formed in the sides of a recess 9 extending transversely ofthe bed. In each recess is inserted a flat electrical heating element,

preferably in close contact with the underside of the bar. The bars are made of a material of high heat conductivity and'preferably of'high specific heat, such, for example, as copper. The folder plates 6, which slide on this bar, are thus heated b contact therewith. These folder plates also rest on washers 10, preferably of antifric-- 13101111161131, which surround the pins of rollers 11 which form projections extending into diagonal slots 12 formed in. the plates .6. Two rollers 11 and two slots are, of course, necessary for each plate and thesev slots may be suitably arranged'to give any desired direction of movementof the folding plates towards one another.

The plates are actuated by two heads 13 which are slidable to and from the form. Preferably these heads are supported on rollers 14 running on suitable tracks on the Links 15 are pivframe of the machine. otally connected with these heads and with the plate 6, two such links being employed.

for each plate. Therefore, as the heads are reciprocated to and from the form, a suit able movement will be given to the plates. As the plates not only move inwardly towards one another, but as will herein after appear, require to be slightly tipped to produce a pressure on the folded edges of the material, the links are given in efiect a Liniversal joint connection both with the heads and with the plates. lVhile any suitable construction may be employed, I show ball-headed studs 16 connected to the plates and tothe heads, while the links are provided with divided sockets 17 suitably secured about the heads of the studs.

The heads 13 are actuated by means of two slides 18 vertically movable in suitable guides at opposite ends of the machine. In each slide is formed a diagonal slot 19 into which project projections 20, preferably formed as rollers. It is evident that by reciprocating the slides that the heads may be moved as desired. These slots may be given any suitable shape to give the heads a. uniform movement or a varying movement as may be required, and the slots are so proportioned that when the slides are really at their lower limit of movement the ends of the slots will engage the projections 20 and thus tip is applied by means of arms 21, two being preferably employed for each of the'folding plates. These arms are provided with slotted lugs 22 by means of which they are bolted to the heads, the slots providing means for adjusting to a limited extent the position of these arms. These arms are provided at their inner ends with means for engagin the upper surface of the folding plates. he engaging means are preferably adjustable. For this purpose I provide a screw, 23 threaded through the inner end of each arm. The upper end of each screw is slotted for engagement with a screw driver, whereby it may be adjusted in the endof the arm. The lower end of the screw is formed as a ball 24 and a divided shoe 25 is secured in position on the ball so as to have a rocking movement thereon. A second shoe is preferably similarly connected to the side of the arm to steady the rear art of the plate and limit the tilting of the p ate. It is not necessary, however, to employ this second shoe except in the case of the outer of the arms 21 as will be seen on reference to Fig. 1.

When the folder plates are moved to their inner positions they fold the edges of the strip of material over the form as indicated particularly in Fig. 3, and the shoes on the inner ends'of the arms 21 then rest on the portions of the plates which project beyond the supporting bars 7, hence the downward pressure of the arms due to the headsbeing tilted as hereinbefore described will impart a downward pressure to the inward edges of 27 suitably v secured together by of rivets or screws. The under plate 27 prefer bly o s not e tend at he inn r s de to he in edge o the pl te 26, so hat he latter projects. A separate member 28 formed of a piece of thin sheet Steel is seemed beneath the extended portion of the upperv plate 26 and extends beyond the same, The

collar-engaging partof each form which is:

most sub ect to wear is thus easily renewed or changed at any time.

n will be noted thet'certainof the rai e plates have thin projec ing portions. 29
