SPECIFICATION forming part of Letters Patent No. 737,216, dated August 25, 1903. Application filed July 28, 1902. Serial No. 117,264. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. FORRY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Can-Headers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in machines for placing the heads in position upon can-bodies. Its object is to provide an automatic machine of simple construction capable of being operated rapidly and in which any danger of injury to the can bodies or tops is obviated.

It consists of a can-body carrier movable about horizontally-disposed sprockets, said carrier comprising pivoted cylindrical jawsegments, means for delivering the bodies in upright position into said jaws, means for insuring the closing of said jaws upon the cans, a can-head carrier rotatable intermittently, a yielding guide mechanism by'which injury to the heads as they are fed from the conveyer-trough into the rotatable carrier is obviated, means for effecting the movement of said last-named carrier by-and relative to the can-body carrier, and means for delivering the can-bodies from the machine.

The invention also comprises details which will be more fully set forth hereinafter, having reference to the accompanying drawings,

body conveyer orcarrier 3.

in which- Figure 1 is a plan view, partially broken away, of acan-heading machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged detail in plan of the can-head-carrier mechanism. Fig. 4 is a part side elevation and part sectional view of the same on linear wot" Fig. 3. Figs. 5 and 6 illustrate enlarged views of the canhead-feeding devices. Figs. 7, 8, and 9 are details of construction.

Arepresents the framework of my machine, supporting the horizontally-disposed sprockets 2 2, around which passes an endless can- A continuous motion is imparted to the carrier through the vertical shaft 4 of sprocket 2 and suitable connection of said shaft with drive-shaft 5. These connections in the present instance include a bevel-gear 6 on shaft 4,,engaging a corresponding gear 7 on the horizontal shaft 8. The latter carries a reducing-gear 9, which engages a pinion 9 on shaft 5, carrying the pulleys 1O 11. and driven from any suitable source of power.

The can-body carrier comprises a series of segmental'jaws linked together and having rollers 12 on the ends of the link-pins, with which the teeth of sprockets 2 2 engage to drive the carrier. The jaws are cylindrical when closed, and the portion above the slot 3 corresponds in diameter to the diameter of a can-body to be headed. The jaws are opened 6 .and closed in the movement of the carrier about the sprockets 2 2', the latter serving to open the jaws to receive the can-bodies, the jaws being subsequently closed while passing in a straight line through the space between the sprockets and sprocket 2 serving to open the jaws again to allow the body with the head in position to be removed. The canbodies 20 are fed into the carrier from the table 13 with their axes vertical and are carried through the machine in thatposition. The feeding of the can-bodies is effected automatically by means of the endless link belt 14, having spacing-fingers 15 engaging the bodies to move them forward between guides 16 17 into the open jaw spaces. The jaws are centrally slotted in aplane at right angles to the axis of the sprockets, as shown at 3. The outer guide 16 extends into these slots, and the fingers 15 move therein, so that a body is sure to be advanced wellinto the jaws before being released. The timing of thetravel of thecarrier and belt 14 is regulated so that the two have a propencoordinate movement. The cans are supported while passing through 0 the machine on the bed-plate18. I.The latter is adjustable to cans of different height by means of screws 18. Passi-ngtoward the left from the feed end, as shown in the present instance, the rollers 12 engage a guide lQ 5 havinga slightly-converted surface by which the rollers are drawn in toward. the center of the machine sufliciently toins-u' rethetight closing and gripping of the jaws on the canbodies. As the body-thus gripped moves'for- 10o ward in a direct line it receives a head or top carried by the intermittently-movable spider 21. The heads (represented at 22) are fed by a belt conveyor 23 beneath the lateral guides 24 and the hinged guide-plate 25 into said spider. The belt is driven by suitable connections 23 with pulley 11 on the driveshaft 5. The spider 21 is fixed to and turnable with the shaft 26, which is suitably journaled' in the frame. The arms of the spider are rotatable in close proximity to the upper surface of the stationary table 27, upon which the can-heads rest after they are received from the belt 23. The table has'an annular groove 28, in which lugs 29 on thelower side of the spider-arms travel, Fig. 3. The table is cut away on the side adjacent to the canbody carrier, and an incline 30 supports the lower edge of the head while it is fed forward from the table into position on the moving can-body beneath. During this part of its movement the can-head is supported and guided from above by the spring-plate 31, under which the head passes before leaving the hinged guide-plate 25. The lugs 29 on the spider serve to advance the head down the incline far enough to insure engagement of the can-head flange with the can-body, as clearly indicated in Fig. 4. The moment the head is in proper engagement with the body the pressure roller 32 is encountered, by which the head is pressed down tightly upon the body. The roller 32 is supported on an arm 33, hinged to the frame, and the pressure of the roller may be regulated by a tension-spring 34. e

In order that the can-heads may be fed properly into the spider, I have provided the following means, (best illustrated in Figs. 5 and 6:) Adjacent to the delivery end of the belt 23 I pivot an arm 35, which carries a segment 36. The latter is pivoted to the outer end of the arm, and the radial portion of the segment carries a projection 37. A link 38 is pivoted to the end of this projection and a fixed support 39, as shown. A spring 40, disposed in the angle between arm and the toggle member 38, tends to press the segment normally into position to be engaged by a can-head as the latter comes from the belt into the spider and to offer a yielding support and guide for the head. The end of the can-head-conveyer trough is suitably cut away to accommodate the segment. With this device all possibility of the heads being buckled or damaged or of injury being caused to the machine by reason of the points of the spider striking a head is obviated. The spider is given an intermittent movement relative to the continuous movement of the canbody carrier and is operated only when a can-body is in position on the carrier to receive a head, so that even though the conveyer may continue its movement if no bodies are being carried no heads will be delivered, as the spider will remain stationary. The manner in which this intermittentrelative movement is effected is as follows: The spider-shaft 26 carries a disk 41, which is rotatable in unison with the shaft. To the under side of the disk are pivotally attached a series of bell-crank-levers 42, corresponding in number and disposition to each other and to the can-head-holding arms of the spider. The longer arms of these levers 42 are adapted to project outwardly into the path of tho can-bodies on the carrier and are movable through the slots 3 in the jaws. These arms are held extended thus by means of springs 43, secured to the disk 41, engaging the shorter arms and pressing the lugs 44 on the under side of the latter against the inner periphery of the flange 45 on the stationary disk 46. The disk 41 is separated from disk 46 by means of a sleeve or hub portion 41. Disk 46 has a sleeve portion 46, in which shaft 26 is revoluble and which is adjustable vertically in a hollow casting 46 by means of a set-screw 46. This is for the purpose of raising and lowering the spider Where different heights of cans are to be run through the machine. A notch or recess 47 is made in the inner side of flange 45, in'which a lug 44 is adapted to engage when the corresponding arm 42 of said lug is in position to be struck by an approaching can-body. In operation as a can-body hits the arm 42 (whose lug is resting in notch 47) the arm first turns slightly on its pivot, carryingthe lug out of the notch and the end of the shorter arm into engagement with an obstruction-as, for example, the shoulder of the arm immediately aheadas would be the case in the machine shown in Fig. 3. The continued movement of the can-body carries the arm, disk 41, and spider along with it. The spider and arms 42 are so disposed on the shaft 26 in relation to each other and to the traveling can-bodies that the spider conveying a can-head will bring the latter down the incline 30 just in advance of its respective body, so that the latter will engage the flange and draw the head onto the body after the spider stops revolving. The spider stops as soon as the canbody leaves the arm 42 and is held against further revolution until the next can comes along by reason of the projecting lug 44 on the succeeding arm dropping into the notch 47. The engagement of the second can-body on the carrier with the projecting arm operates the arm and spider, as before described, to deliver a can-head at the proper moment. The lugs engaging successively the notch 47 at each interval in the intermittent revolution of the spider always prevents the latter moving too far, and so possibly causing a canhead to fall prematurely through the tableopening. Thus it is seen that so long as there are no can-bodies passing through the machine the spider-conveyer will remain stationary, or, in other words, the latter will only be actuated when a body engages one of the arms 42. Passing beneath the pressure-roller 32 the headed cans are carried around sprocket 2 to open the jaws, from which they are ex.- tracted by means of the fingered link-carrier 48 with the assistance of the guide 49. The carrier 48 is similar in construction and opertall cans.

. supported on all sides is in handling canbody true up the end opening, so that a can- I claim, and desire to secure by Letters Pat'- adapted to extend into the path of the bodies ation to carrier 14, previously described, and l is run at a relatively greater speed'than the can-body conveyer to effect its purpose. The cans pass into a trough 50 and thence onto a belt-carrier 51, by which they are delivered to the crimper or soldering-machine.

This machine is readily adapted to flat or In the present instance it is shown adjusted to the former. For cans of greater height the pivot of roller-arm 33, Fig. 2, would be shifted to perforation 33 and the bed-plate 18 lowered by means of the adj listing-screws 18*, which support the plate on the frame. If necessary, a can-conveyer having jaws of different height and diameter may be inserted.

The end of the can-head-conveyer trough and the table 27 are movable in unison on the bracket 52, which is slidable in guides 53 and is locked in position by a screw 54: passing through a lug on the back of the bracket and engaging the frame. The position of screw 54 is simply indicated in Fig. 2. The spider 21 is adjustable in relation to the table 27 in the manner before described. Y

A particular advantage of this header over others commonly in use where the body is not bodies which for some reason have become pressed slightly out of their circular shape. The segmental jaws 3 when they embrace the head will fit down smooth over it.
