Specification of Letters Patent.

FASTENER-SETTING MACHINE.

Patented Apr. 20, 1920.

Application filed September 16. 1918. Serial No. 254.238.

To all whom it may concern:

Be it known that I, PATRICK J. HoRGAN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastener setting machines and will be herein shown and described by way of example in connection with an eyeleting machine.

In most eyeleting machines the eyelets are delivered to an eyelet-inserting tool by a raceway which is reciprocated automatically so as to move the delivery end to and from a delivering position in registration with the inserting tool. It is obvious, therefore, that the raceway must be retracted from the path of inserting movement of the tool during the stroke of the tool toward the work. In some machines wherein the inserting tool is utilized to feed the work the retractory movement of the raceway follow lines substantially transverse to the lines of the feeding movement, but in machines of other types, for example that shown and described in Letters Patent of the United States No. 934,066, granted September 14:, 1909 upon application of George Goddu, the organization is such that the delivering and retractory movements of the raceway-end must follow the path of feeding movement of the feeding tool. Under the latter conditions the retractory movement of the raceway must be of suflicient amplitude to provide clearance for the tool with respect, not only to its inserting movement, but to its feeding movement, which amplitude is, of course, dependent upon the maximum length of feeding movement, and consequently if the feeding mechanism is altered so as to diminish the length of the feeding steps the retractory movement of the raceway could, advantageously, be diminished accordingly, but so far as I am aware this has never been done. The excess movement on the part of the raceway and its operating mechanism sets up unnecessary vibration in the machine as a whole and causes unnecessary wear of the operating mechanism.

Accordinglyan object of the present invention is to provide improved racewayoperating mechanism adapted to be regulated with re ard to the amplitude of delivering and retractory motion imparted to the raceway consistently with the length of feeding movement for which the work-feedlng mechanism is adjusted, to the end that all unnecessary vibration and wear may be obviated.

Another object of the invention is to provide racewayoperating mechanism controlled by the work-feeding mechanism so that the extent to which the delivery end of the raceway is retracted to clear the inserting tool will, in every case, be determined by the same adjustment that determines the length of the work-feeding movement.

Still another object of the invention is to provide mechanism constructed and arranged to operate the feeding tool and the raceway collectively in such manner that the feeding movement of the one and the clearing motion of the other will be imparted by a reciprocatory actuator common to both.

Features of the invention will become apparent upon a consideration of the following specification describing the preferred embodiment of the invention and referring to the accompanying drawings, in which- Figure l is a top view. partly in section, of the parts of an eyeleting machine embodying my invention, and

Figs. 2 and 3 are fragmentary views showing these parts in successive operative positions.

Reference may be had to the above-mentioned Goddu patent for a description of the parts of the machine not herein fully shown and described. In general, however, it will be understood that the machine embodies a driving shaft 10 provided with a series of cams 12, 14 and 16, this shaft being mounted in a framework 18. Punching and setting tools 20 and 22 are carried in a movable head 24 pivotally mounted at 26 upon a bell crank lever 28 pivoted to the frame of the machine and controlled by the cam 14:. By means of this cam controlled lever the head 24: is moved toward and away from the operator to bring the respective tools successively into operating position. Lateral feeding movement may be imparted to the setting tools by means of cam lever 30 con trolled from the cam 12 and connected to the head 24 by means of links 32 and 3 1-.

Adjustment of the extent movement is effected by movement of a control handle 36 pivoted upon the frame of the machine and adapted to be held in any one of a plurality of positions by means of a pin 38 inserted in one of the holes of a quadrant &0. This lever 36 supports a link 42 acting as a fulcrum for the connecting point between the links 32 and 34, and, according to the position of the lever 36, more or less of the fixed-movement of the cam operated lever 30 is transmitted to the tool carrying head 24.

Fasteners are supplied to the setting'tools from a hopper 50 through raceways 52, 54, this hopper being pivotally mounted upon a bracket 56 attached to the frame of the machine and movable about a point concentric with the hopper itself. Movement of the tool carrying head 24- is transmitted to the raceways and incidentally the hopper by means of an arm 58 attached thereto and connected by links 60 and 62 to the tool carrying head. When these links are maintained in alinement, it will be apparent that the movement of the tool carrying head is imparted directly to the raceways. The connection between said head and the race ways may, however, be altered and for this purpose a link 64c is arranged to connect links 60, 62 with a bell crank lever 66, which is operable by the cam 16. Nhen the link 64: is drawn backward as shown by Fig. 2 the effective length of links 60, 62 is shortened so that the end of the raceway takes its delivering position relatively to the eyelet-inserting tool. When the latter has impaled an eyelet the cam 16 will straighten the links 60,62to impart'the first stage of retractory movement to the raceway.

In operation, then, the punches will be depressed in the usual manner to erferate the work, and the tool carrying head will then be retracted by the lever 28 to shift the inserting tools into alinement with the previously punched holes. At this stage the ends of the raceways will be shifted into alinement with the inserting tools, as shown in Fig.2. As soon, however, as the eyelets have been impaled by the-inserting tools the cam 16 will impart the first stage of retractory movement to the raceways, thereby shifting the delivery ends to the position shown in Fig. 3. Inasmuch as the rest of the retractory movement of the raceways is always commensurate with and determined by the extent of feeding movement imparted to the tool carrying head, it will never be eX- cessive even when the feeding mechanism is set for the minimum stroke.

Having thus described my invention. what I claim as new and desire to secure Letters Patent of the United States is:

1. In a fastener-setting machine, workfeeding means including a fastener-insertof feeding ing and work-feeding tool, means for varying the amplitude of feeding movement imparted-by the feeding means, a raceway the delivery end of which is movable in one direction to carry a fastener to delivering position and in the opposite direction to clear the tool, and mechanism controlled by the work-feeding means for reciprocating the delivery end in said directions with an amplitude of movement determined by that of the work-feeding movement.

2. In a fastener-setting machine, workfeeding means including fasteneninserting and work-feeding tool, a raceway the delivery end of which is movable relatively to said tool to deliver fasteners thereto, and raceway-operating means controlled by'tlie work-feeding means for moving the delivery end in opposite directionsto and from delivering position.

8. In a fastener setting machine, a setting tool, a carrier therefor movable laterally to effect feeding of the work, means for adjusting the extent of feeding movement imparted to the carrier, a raceway forsupplying fasteners to the setting tool, and means for moving the raceway to and from fastener delivering position with a stroke the amplitude of which is determined by the-adjustment of the feeding mechanism.
