MACHINE FOR HANDLING CAN-HEADS AND THE Application filed August 24, 1910. Serial No. 578,742.

To all whom it may concern:

Be it known that I, O'rro DEMPEWOLF, a citizen of Brunswick, Germany, have invented certain new and useful Improvements in Machines for Handling Can-Heads and the like, of which the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a machine for packing and handling can heads so that they are in convenient condition for further operations. I

The object of the invention'isto provide a machine for automatically removing the can heads from holders where a certain operation has been performed on them and for automatically stacking the heads in suitable galleys.

In carrying out the invention, I provide a moving table on which thedesired operation isperformed on the can heads, for instance, the placing of a gasket or packing ring therein. Coacting with the table is a device by which the heads are removed from the table rand distributed automatically into suitable galleys or compartments. In so operating on the can heads the rotation or other movement of the table is'utilized to operate an automatic stop for the can heads and to enable the number of heads handled to be noted at a glance.

The invention involves various other fea tures of importance, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is now had to the accompanying drawings which illustrate, as anexample,

the preferred embodiment of the invention.

In these drawingsFigure 1 is a front elevation of the machine part thereof being shown in section; Fig. 2 is a side elevation; Fig. 3 is a plan view; and Fig. 4 is an enlarged section of one of the can head holders.

10 indicates the table, which is hereshown as mounted. to turn in a horlzontal plane around a vertical supporting shaft 11. The

motion of the table is intermittent and may be brought about by any desired mechanism (not shown). On this table are mounted a number of head holders shown in detail in Specification of Letters Patent.

Patented Feb. 2, 1915 Fig. 4 and comprising pedestals 12 having cups 14.. In these cups are located two vertically movable cups 15 and 16. The cup 16 is nested within the cup 15 and both of these cups have independent motion with respect to each other and to the cup 14. Springs 17 sustain the cup 15 and springs 18 sustain the cup 16, said springs pressing'on the bottoms of the cups and supported respectively by the cup 14 and cup 15. These springs are of such relative tension that normally they hold the parts as in Fig. 4;, wherein the up per edge of the cup 15 is slightly above the upper edge of the cup 14 and the upper edge of the cup 16 is slightly above the upper edge of the cup 15. During the period of rest in the intermittent movement of the table 10, the holder which is alined with the heating 1683, 19 is brought into contact with said ea I 7 The can head is indicated at a and it will be observed that its edge a is crimped to I produce an inverted channel extending around the edge of the head. This head is placed on the holder so that said channel receives the upper edges of the cups l5 and 16. b indicztes the packing gasket, which is annular to correspond with the channel in the head a and this is placed around the cup 16 on the upper edge of the cup 15.

The heating head 19 is provided with suitable heating means (not shown) and when a head holder with the head and gasket in place thereon moves under the heating head 19 the parts will assume the position shown in Fig. 4. The heating head then moves downward and the springs 18 and 17 are compressed,'the springs 18 yielding first. This causes the upper edges of the cups 15 and 16 to become coincident with each other causing the gasket 6 to be flattened or spread out. The heat of the head 19 softens the gasket and causes it to spread out in a relatively thin sheet in the bottom of the aforesaid inverted channel extending around the edge of the head a. The cup 14.- is provided interiorlv at its upper edge with an annular inwardly tapering surface 14"; and

the continued downward movement of the head a brings its outer wall or flange against the surface 11 bending said flange inwardly preparatory to the operation of seaming the head on the body of the can. This operation. of the surface 14 need not necessarily be outlined at'20. This operation as well as that of placing the gasket 6 on the holders maybe performed in any desired manner without departing from the spirit of my invention. That is to say, the heads and gas kets may be'manually placed on the holders or automatic mechanism may be provided for this purpose. In Fig. 3 the position of the heating head is diagrammatically indicated at 19. This also'may be mounted and operated in any desired manner, either manually or automatically. The table is assumed to be rotating intli'e direction of the arrow in Fig. 3 so that it passes from the chute 20 to the heating head and thence on to the other elements of the machine as will hereinafter fully appear.

'21 indicates a chute, which slants downward tangentially from the periphery of the table 10." At the receiving end of this chute curved lifting and guide fingers 22 are disposed so that as the can heads on the holders are moved from the gasket applying position at the heating head 19%(referred to Fig. 3) they ride over the guiding fingers 22 and are caused to roll outward toward the periphery of theytable, where with the aid of a guiding finger 23 said heads are tilted edgewise and dropped into the chute 21. The guidingfingers 22 are supportedin any suitable manner, for example, on a brace 24, extending between the receiving end of the chute 21 and a stationary collar or like member 25 on the column 11.

The chute 21 has a transversely sliding bottom 26 of graduated width corresponding to a series of pockets 27. Controlled by the transverse position of said bottcm 26 the can heads will roll on edge down the chute 21 until they reach a point where the.

width of the bottom 26 with regard-to its relative position to the-chute is such that the chute is open at the bottom and no support provided for the heads, whereupon the heads must and will fall into the particular pocketbelow the point referred to. At the inception of the operation the bottom 26 is moved to its extreme rightward position (referring to Fig. 3) leaving the chute open at the bottom only at the extreme end pocket. The can heads therefore fall into this particular pocket. hen the pocketis filled the bottom 26 is moved toward the left a sufficient distance to openthe bottom ofthe chute at the next adjacent pocket allowing this to be filled, and so the operation proceeds until all of the pockets are filled. l-Vhen the bottom 26 reaches its extreme inward or leftward pos t-ion a stop 28 attached In Fig. 3 a chute for feeding the can heads to the holders is ferred that the operation. be automatic, and

to this end said bottom is provided with a tang 29, which is mounted to slide horizontally with the bottom in a bearing 30. This tang has a handle 31 attached, thereto for its manual operation and it also has a ratchet bar 32adapted to be engaged by a dog 33 fixed to-the ratchet wheel 34 once forcach revolution for a ratchet wheel 34:. To this end said dog and wheel are connected to a common shaft 35 which is suitably mounted in a vertical'position at the periphery ofthe table 10 but in a plane below that of the table. To the underside of the table 10 is fixedly attached a dog 36 which isarranged to engage a tooth of the ratchet 34 once. for each revolution of the table. The resultof this arrangement is that each time the table is rotated the ratchet wheel 34: is moved one tooth and each time the ratchet wheel is rotated the ratchet bar 32:

is moved one tooth. The parts are so proportionate and organized that when this movement of the ratchet bar takes place a sufiicientv and predetermined number of heads will have passed over the table '10 through the chute 21 to fill one of the pockets 27 and said movement of the ratchet bar brings about a movement of the chute 26 sufficient to uncover the next adjacent pocket The number of teeth on the ratchet'bar is, at least, e ual to the number of pockets so that when t e movement of the ratchet bar is exhausted the end of one complete operation of the machine will be marked. It readily follows that the number ofheads made in thismanner may be easily counted connected to the wheel 34 or another of the moving parts by which to show the number of heads at any period in the operation.

The pockets 27 are formed by suitable partition walls preferably-consisting of a continuous backing wall 37, partitions 38, separating the pockets and a removable front wall 39. These walls are disposed at a slight inclination to the vertical and the pockets formed thereby are i of less width in one direction than the widthof the can heads so 7 I i and indeed an indicating attachment may be that the heads as they stack in the pockets I take overlapping inclined positions as indicated in Fig. 2. The said walls forming the pockets are preferably mounted on pivots 40 at the bottom so that upon removing the front wall 39 the walls 37 and 38 may be rocked forward or. away from the other part of the machine, thus. allowing the accumulated. heads to be dumped from the pockets into the box or other suitable storage or transporting means in which the heads may be stored or carried to the next stage of the operation of the manufacture ofthe cans.

In its organized operation therefore the machine receives the heads which have been previously flanged and impresses the gaskets into the channels in theedges of the heads. After this the heads are automatically lifted from the holders and turned edgewise into the chute through which they run to the pockets. Meanwhile, an automatic step by step motion in a transverse direction is 1mparted to the bottom 26 causing the pockets to fill successively and finally resulting 1n the closing of the chute against further movement of the heads therein. If desired, this operation may be made to take place concurrently with the automatic or other stoppage of the table 10. after again starting the motion of the table, the bottom 26 may be returned to starting position manually through the handle 31, which operation simultaneously withdraws the stop 28 and allows a resumption of the movement of the heads in the chute- Having thus described my invention, what I claim as new and desire to secure by Let ters Patent of the United States, is:
