RIVET-SETTING ltfACI-IINE \VITH HORK-POSITIONIN G ltIEANS.

Application filed May 1, 1924.

To all whom it may concern.

Be it known that I, ARTHUR R. HAVENER, a citizen of the United States, residing at Wayland, in the county ofMiddleseX and State of Massachusetts, have invented new and useful Improvements in Rivet-Setting Machines with Work-Positioning Means, of which the following is a specification.

This invention relates to a rivet setting machine with means for positioning the work to receive a rivet.

The invention is particularly adapted to be used in connection with rivet setting machines for riveting metal reinforcing strips to trunks and other receptacles. The positioning means, however, is adapted to be used in connection with any riveting machine for positioning the work to be riveted, upon the work support in correct alignment with the rivet driver of the machine.

The invention consists particularly in the work positioning device, or mechanism, in combination with the rivet setting instrumentalities of a rivet setting machine.

The invention further consistsin the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings:

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 11 is the frame of the machine, 12 is a work supporting arm fast to, or integral with, a standard 13 upon which the frame 11 is mounted, 14 is the work supporting standard, 15 is an anvil constituting a work support, 16 is a rivet driver fast to a slide 17 to which a vertical reciprocatory motion is imparted by a pair of toggle links 18 and 19, the toggle link 19 being pivotally connected at one end thereof by a pivot pin 20 to the rivet driver slide 17. The other toggle link 18 is connected by a pivotal pin 21 to a pair of standards 22 forming a portion of the frame. Therear ends of the links 18 and 19 are pivotally connected by a pin 23 to a link 24 which, at its rear end, is pivotally connected to a wrist pin 25 fast to a cam plate 26, driven by a shaft 27, Fig. 2, fast thereto, said shaft being rotated by a gear 28 which meshes into a pinion 29 fast to the main driving shaft 30 which, in turn, is driven by a pulley 31. Rivets contained in a hopper 32 are fed in a manner well known to those skilled in the art down a raceway 33, and an auxiliary raceway 34, and are fed one by one from said auxiliary raceway into a rivet carrier 35 which comprises two parts 36 and 37 supported upon fiat springs 88 and 39 which, in turn, are fastened to a rivet carrier slide 40, slidably mounted in the frame of the machine to which a vertical reciprocatory motion is imparted by a lever 41, which is slotted at its front end at 42 to receive a pin 43 projecting laterally from the rivet carrier slide 40, see Figs. 1 and 2. The lever 41 is pivoted at 44 to the frame of the machine and has a cam roll 45 rotatplan taken on the .ably mounted upon the rear end thereof,

and engaging the cam 26.

The rivet hopper, the pulley 31, shaft 30, pinion 29 and gear 28 are constantly rotated during the operation of the machine, and the gear 28 is intermittently locked to the shaft 27 by a clutch 46 which is thrown into operation to lock the gear 28 to the shaft.27 by links 47 and 48, which are connected to a foot treadle, not shown in the drawings, in a manner also well known to those skilled in this art.

The particular article to be riveted, a por tion of which is illustrated in Figs. 5, 6, 7 and 8, consists of a piece of wood 49 and a strip of metal 50 thereon, such, for example, as the strips of metal used for reinforcing the corners and different portions of a trunk. The strip of metal has holes 51 punched therein before being applied to the trunk, and the positioning means embodies a pin 52 fast to and projecting downwardly from an arm 53 which is fastened to the lower end of a vertical rock shaft 54. The positioning means and the driver are both located above the work contacting surface of the work support or anvil 15. The rock shaft 54 is mounted in bearings 55 and 56 formed in a bracket 57 fast to the frame of the machine, and a vertical reciprocatory motion is imparted to the rock shaft 54 by a lever 58 which is pivoted at 59 to the frame of the machine. The front end of the lever 58 terminates in a handle portion 60, whereby it may be manually operated when desired.

The rear end portion 61 of the lever 58 bears against the lower edge of one arm 62 of a lever 63which is pivoted at 64 to the frame 11, and has another arm 65 projecting upwardly therefrom and contacting adjacent its upper end with a roll 66 journalled upon a stud 67 which is fast to the link 24. A spring 68 is connected at the upper end thereof to a stud 69 fast to the rock shaft 54 and projecting laterally therefrom. The lower end of the spring 68 is fastened to the stop bracket 71. The action of the spring 68 is two-fold as regards the rock shaft 54. It pulls downwardly upon said rock shaft, and at the same time pulls laterally upon the stud 69, tending to rock said shaft in the direction of the arrow a, Fig. 6. The stud 69 has a cam roll 69 journalled thereon and adapted to engage a cam 72 fast to the bearing 56 on the bracket 57, see Figs. 2 and Vihen the rock shaft 54 is moved upwardly by the mechanism hereinbefore described, the lever 58 engages a collar 73 fast to the rock shaft 54, whereby the rock shaft is moved upwardly, said collar 73 being held constantly in contact with the lever 58 by the spring 68 during the operation of the mechanism.

The centering pin 51 is positioned in direct alignment with the driver 16, as shown in F g. 6 by a stop arm 74 fast thereto, and having a stop screw 7 5 adjustably fastened thereto and locked in position by a lock nut 7 6, see Fig. 4. When the arm 7 4 is in the position illustrated in Fig. 6, the screw 7 5 abuts against the stop bracket 71 which is fastened to the bracket 57, and the work is moved to bring one of the holes 51 in the metal strip in alignment with the centering pin 52, the centering pin will drop, together with the arm 58, and the rock shaft 54, so that the centering pin will project through the metal strip 50, as illustrated in Fig. 5, the downward movement of the rock shaft 54 and the arm 53 being assisted by th spring 68. At the same time the arm 53 and its centering pin 51 will be locked against lateral movement by a pin 77 in the stop arm 74, which will enter a hole 8 in the stop bracket 71, see Fig. 4.

When desired, the lever 58 may be rocked by hand to lift the rock shaft 54 and the parts attached thereto, so as to throw the arm 53 out of operation and when the lever 58 is so operated, a stop pawl 79 pivoted at 80 to the lever 58 will drop into engagement with the upper end of a stop plate 81 fast to the bracket 68 and will thus hold the rock shaft and the parts connected thereto out of operative position while the work is being inserted in the machine, or whenever it may be desired to throw the positioning leans and its operative mechanism out of operation.

As will be seen by reference to Figure 10, the vertical work supporting standard 14 is triangular in cross section with the anvil 15 located in the front apex of said triangle. A steel block 88 is inserted in the upper front portion of said standard 14 and is held in position by two screws 84. The anvil 15 is held in position by a clamp screw 85 which has screw-threaded engagement with the standard 14 and with the block 88 forming a part thereof, and bears against a stem 86 extending downwardly from the anvil into the block 83. It will be seen that by having the anvil located on a work supporting standard of the form hereinbefore described, that the operator can swing the trunk to any desired position in order to insert rivets therein.

The general operation'of the mechanism hereinbefore specifically, and to some extent in general described, is as follows: The positioning arm 53 and centering pin are thrown upwardly and backwardly by means of the lever 58 which is raised by the operator as hereinbefore described. The trunk 49 with metal strip already punched and laid thereon is then placed by the operator upon the anvil 15 which constitutes a portion of the work support. He then disengages the pawl 79 from the upper end of the stop plate 81 and releases the lever 58, whereupon the spring 68 will. draw the rock shaft 54 downwardly and the roll 69 will be drawn out of contact with the cam 72, and

the pin 77 which will enter the hole 7 8 in Fig. 8.

the stop plate 70. The metal strip'is now in position to hav a rivet 82, see Fig. 5, inserted through the hole 51 in which the centering pin 52 is at this-time located and to have the rivet driven through the wooden portion 49 of the trunk, riveting the two parts, the ,metal strip andthe wooden portion 2f the trunk together, as illustrated in Fig.

In order that this may be accomplished, however, the arm 53 and the centering pin 52 must be moved from the position illus trated in Fig. 6 to the position illustrated in The operator, therefore, operates the treadle to throw the clutch 46 into opera tion and lock the gear 28 to the shaft 27, whereupon the shaft 27 will be rotated in the direction of the arrow Z), Fig. 2, and the wrist pin 25 will move the link 24 forwardly, operating the toggle links 18 and 19 to move the driver 16 downwardly, and simultaneously the cam 26 will operate the lever 41 to move the rivet carrier slide 40 and the ivetcarrier 35 downwardly.

At the same time that the link 24 is moved. forwardly to operate the toggle links 18 and 19 and move thedriver 16 downwardly, the roll 66 will rockthe lever 63 T and move the arm 62 thereof downwardly,

which, in turn, will rock the lever 58 to move the rock shaft 54 upwardly. During the first part of the movement of the rock shaft 54 upwardly, the centering pin 62 will be withdrawn frcmthe metal strip 50, and the locking pin 77 will be withdrawn from the hole 78 in the'stop plate 70, and when th s has been accomplished, the roll 69 on the.

stud 69 will engage the cam 72 and the rock shaft will thereby be rotated upon the further upward movement thereof to move the arm 53 out of alignment with the driver 16. from the position illustrated in Fig. 6 to that illustrated in Fig. 8.

The rivet carrier upon its downward motion will position the rivet held in the rivet carrier above the hole 51 and the rivet 82 will then be driven out of the rivet carrier through the hole 51 in the metal strip 50 and through the wooden portion49 of the trunk, and the bifurcated end of the rivet engaging the anvil 15 will be clinched thereby in the wooden portion 49 of the trunk.

The parts will then return to the relative positions illustrated in ig. 1, and the machine will automatically stop by reason of the clutch operating to disengage the gear 28 from the shaft 27 At this time, the le- 10 vers 65 and 58 will be in the positions illustrated in Fig. 2, the roll 69 will be out of engagement with the cam 7 2, and the spring 68 will have rocked the rock shaft 54 in the direction of the arrow a, so as to bring the 76 arm 53 into the position illustrated in Fig. 6 and bearing against the head of the rivet which has just been set.

Now the operator moves the strip and the trunk to which it is attached by the rivet previously set toward the. left, Fi' 5, until the next hole 51 comes into alignment with the centering pin 52, whereupon said centering pin will enter the hole 51 and the parts will then be in position for the operation of setting another rivet as here inbefore described.
