UNITED STATES PATENT JOHN M. SHERWIG- AND MORTON G, PETITT, OF CLEVELAND, OHIO.
Specification of Letters Patent.
Patented Aug. 9, 1910.
To all whom it may concern:
Be it known that we, JOHN M. Snnnwre and MORTON C. PETITT, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Button-Making Machines, of which the following is a specification.
This invention relates to that class of button making machines characterized by a reciprocating die, and a pair of stationary dies which are alternately swung into operative relation with respect to the reciprocating die.
The object of the present invention is to provide an improved mechanism for operating the reciprocating die, and also to provide a connection between said mechanism and the carrier of the stationary dies, where by the movement of said carrier to shift the stationary dies is effected simultaneously with the operation of the reciprocating die,
thus enabling the operator to place the Inaterial in position with one hand and with the other hand operate the machine.
With the foregoing object in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawings hereto annexed in which- Figure 1 is a side elevation of the ma chine; Fig. 2 is a front elevation; Fig. 8 is a horizontal section on the line 3030 of Fig. 1; Fig. 4: is a rear-end view of a portion of the machine.
Referring more particularly to the drawings, 1 denotes a standard rising from a sultable base 6. At the upper end of the standard is a bracket which is formed with vertically spaced bearings 5 and 5 in which is mounted a vertically reciprocating plunger 12, to the lower end of which, below the bearing 5, is fitted the die 11. The die 11 has a sliding connection with the plunger 12, said connection being made by a set screw 11 passing through the die and into a longitudinal slot made in the plunger. From the bearing 5 rise checks 1 between which the upper end of the plunger extends, and between said cheeks is fulcrumed at 2 1 an operating lever 26. The toe 25 of this lever is cam shaped, and engages theupper end of the plunger, so that when the lever is swung on its fulcrum in one direction, the
plunger will be depressed.
The stationary dies are indicated at 9 and 10, respectively. Both of these dies are mounted on a carrier 8 which swings in a horizontal plane, so that the dies may be alternately brought into operative posltion with respect to the die 11. The standard is formed with a recess 32i11to which the car rier extends. In this recess is mounted a vertically disposed rod 28 to which the carrier is pivota ly. connected so as to swing in a horizontal plane as stated. On thecarrier is an upstanding flange 8 having bearing lugs 8 on opposite sides, which are for a purpose to be presently described.
To the standard 1 is pivoted at 29, to swing in a vertical plane a lever 17 having at its upper end a head 1 and at its lower end a fork 17 between the branches of which the flange 8 is received, and said branches engaging the lugs 8 Below the bearing 5, the plunger 12 has a transverse opening in which is pivoted the inturned end 14 of a rod 14:, and between said end 14*, and the bearing 5, a spring 13 is coiled around the plunger. The part 14L engaged by one end of the spring is flattened as shown in Fig. 1. The rod 14 extends downwardlyto the die 11 and is then bent inwardly over the top thereof and in contact therewith. The last mentioned bend ter minates in a downward bend, at the lower end of which is another inward bend 1 1 engageable with one side of the fork 17*.
To the heel of the lever is pivoted at 21 a trip comprising a pair of fingers 20 and 20 which extend at right angles to each other. This portion of the lever also has a shoulder 22, which has a purpose to be the bearing 5. At their lower ends, the rods rest on the head 17".
In line with the axis of the plunger 12, the base has a raised portion 7 on which that end of the carrier on which the dies 9 and 10 are mounted slides, and which serves to take up the shock of the blow and thus prevents injury to the table, the dies when they are in so as to bring the die 9 below the die 11, and
the rod 14 over the edge of the die 11, and the lever is then swung to depress the plunger. The plunger 12, is kept from participating in thefirst operation, the rod 14 holding the die below the end of the plunger. In the meantime the rod 31, by the swinging movement of the lever 17, is elevated, so that its upper end is higher than the upper end of the rod 19. Then, when the lever 26 is raised, the trip finger 20 lowers and strikes the upper end of the rod 31, and said finger engages the shoulder 22, thus forcing the rod 31 downwardly. This movement of the rod, by reason of the engagement of its lower end with the head 17 of the lever 17 swings the latter, thus forcing the rod 19 upwardly, and pushing the rod 14: to the position of dotted lines in Fig. 2, off the die 11. At the same time, the carrier 8 is swung so as to bring the die 10 in position beneath the die 11, by reason of the engagement of the fork 17 with the flange 8. Then by swinging the lever 26 forwardly, the second operation takes place, the plunger 12 being brought into play with the die 11 inasmuch as the latter is free of the rod 1 1. hen the lever 26 is again swung back, the rod 19 is forced down by the trip finger 20, and the rod 31 rises. The rod 14: swings over onto the die 11 by reason of the spring compression on the flat surface 14 The lever 17 having been swung over, the die 9 is again under the die 11, and the parts are then in position for the neXt operation.
The trip falls by gravity, so that the fingers 20 and 20 extend over the upper ends of the rods 19 and 31, respectively, as the lever 26 is swung back. However, should the trip fail to fall, the lugs 23 will force it into proper position to operate as herein described.
The machine allows the work to be placed on the dies 9 and 10 with one hand, leaving the other hand free to operate the lever 26; or said lever may be operated by foot power, or in any other convenient manner, thus doing away with the trouble. and time consuming operation of shifting the carrier 8 by hand.
