MULTIPLE RIVET-SETTING MACHINE.

Specification of Letters-Patent.

Patented Feb. 27, 1912.

To all whom, it may concern:

Be it known that I, ARTHUR R. l-IAVENER, a citizen of the United States, residing at l/Valtham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Multiple Rivet- Setting Machines, of which-the following is a specication.

This invention relates to an improved machine for setting rivets and the like in sheet material.

The object of the invention is to provide a machine which can be readily adapted to set rivets of different sizes, so that with a machine occupying about the floor space of a single machine, rivets can be set, which, by the use of the ordinary single machine, would require several separate machines to produce the same result. This result is obtained by using a single column and actuating mechanism and mounting upon said column4 a rotary carrier to which is attached a plurality of complete rivet setting mechanisms, each of which is adapted t-o be operated successively by said actuating mechanism. The machine is so arranged and constructed that the actuating mechanism cannot operate in one of the setting mechanisms until one of said setting mechanisms shall have been properly positioned and locked in that position.

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

Referring to the drawings: Figure 1 is a side elevation of my improved multiple rivet setting machine, one of the heads being broken away and shown in section. Fig. 2 is a vertical sectional elevation taken through the center of the machine and through the center of two heads, the same being broken away to save space in the drawings. Fig. 3 is a plan view of the stop plate. Fig. 4 is a plan view of the central portion of the machine, with a portion of the rivet setting mechanisms shown therein and broken away to save space in the drawings, the stop plate being removed. Fig. 5 is a side elevation of a portion of a column and base illustrating the manner of attaching the treadle to the rod which actuates the rivet setting mechanisms.

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

In the drawings, referring to Figs. 1 to 4, inclusive, 5 is the base of the machine and 6 the column which terminates at its upper end in a cylindrical portion 7. A sleeve 8, constituting a carrier, is rotatably mounted upon the cylindrical portion 7 of the column and rests at its lower end upon a liange 9 on said column. To the sleeve 8 are fastened a plurality of organized rivet setting machines, in this case four in number, 10, 10, 10, 10.

The different rivet setting mechanisms are duplicates of each other and each consists of a suitable frame 11, an anvil 12, a plunger or driver 13 and a pocket 14 to which the rivets are fed down a raceway 15 from a suitable hopper 16. A rotary motion is imparted to the separating mechanism of the hopper and a reciprocatory motion is imparted to the plunger 13 by an actuating lever 17 pivoted at 18 to the frame 11 and having an arm 19 which projects toward the median axial line of the carrier 8. The other arm 20 of the lever 17 is connected by a link 21 to a lever 22 pivoted at 23 to the frame of the machine and connected by a link 24 to the upper end of the plunger 13. t

A link 25.connects the lever 22 to another lever 26 which is pivoted at 27 to the frame of the machine and has a pawl 28 pivotally supported thereon, which'pawl engages a ratchet 29 fast to the rotary shaft 30 of the hopper. The lever 26 also has an arm 31 thereon which engages a lever 32 and operates the separator slide 33 which separates the upper part of the raceway from the lower part, and thus feeds the rivets one by one, from the upper to the lower part in a manner well known to those skilled in this art.

Nothing new is claimed in the specific mechanism hereinbefore described for setting and feeding the rivets.

The sleeve 8 and consequently the different heads attached thereto or different rivet setting mechanisms att-ached thereto, is

locked in position by means of a locking lei ver 34 pivoted at 35 to the column 6. The upper end of said lever projects into one of the notches 35 provided in the flange 36 at the lower end of the sleeve 8. Four of these notches are provided, one for each of the rivet setting mechanisms. A spring 37 draws the upper end of the locking lever 34 toward the sleeve 8. y

Each of the rivet setting mechanisms is operated, in its turn, by a rod 38 which is hooked at its upper end 382 to extend over the end of the arm 19 of the actuating lever 17 of that particular rivet setting mechanism vwhich is in the position indicated at the left of Figs. 1 and 2. The rod 38 is pivotally connected at its lower end to a lever 39 pivoted at 40 to the column 6. To this lever 39 a rocking motion is imparted by means of an eccentric 40 and eccentric strap and rod 41. The eccentric 40 is fastened to the driving shaft 42 which, in turn, is rotatedv by a clutch pulley 43, said clutch pulley being operated to connect or disconnect the same from the shaft by means of a lever 44 pivoted at 45 to the column 6 and held in its upward position, as illustrated in Fig. 1, by a spiral spring 46. Said lever 44 is drawn downwardly by a treadle 47 to which it is connected by means of a link 48. The rod 38 is guided at its upper end by passing between two ribs 7 7 inside the column 6.

In order to prevent the treadle from being operated and the rod 38 and its hook from being loweredwhen no one of the setting mechanisms is in proper position to set a rivet, a locking rod 49 is pivoted at its lower end to the treadle 47 and extends upwardly therefrom, terminating at its upper end in a hook 50, which, when the parts are in the position illust-rated in Fig. 2 and the heads locked in position, is free to play up and down, but when the lever 34 is tipped into the position illustrated in Fig. 2 in dotted lines and the upper end of said locking lever is-bearing against the outer periphery of the flange 36 instead of being locked within one of the notches 35, then said hook projects into the recess 51 above the tooth 52 formed upon the rear edge of said lever 34, and in that case the rod 49 cannot move downwardly and, therefore, the treadle 47 cannot move downwardly to operate the rod 38 for the purpose of actuating the lever 17 which operates the rivet setting mechanism.

Instead of the rod 38 being connected to a power operated mechanism, as shown in Fig. 1, said rod may be extended downwardly and directly connected to the treadle, as illustrated in Fig. 5, in which 5 is the base, 6 the column, 47 the treadle and 38 the rod which is pivoted at its lowerend to said treadle and'at its upper end is hooked to extend over the actuating lever of one of the rivet settingmechanisms. A spring 53 holds the treadle 47 upwardly, as well as the rod 38 and the hooked end of said rod bears against the under side of a stop plate 54 (Figs. 1 and 2) leaving a clearance beneath the lower edge of the hook and the upper end of the arm 19.

The stop plate 54, it will be noted, is provided with a curved recess 55 upon its under side, which serves to guide and position the curved end 382 of the rod 38, or the curved end of the upper end of the rod 38', as the case may be, thus positioning said hooked end above the outer end of the lever arm 19 in readiness and in proper position to be brought downwardly into engagement with said arm at the proper time. hen the forni of my invention illustrated in Fig. 5 is used, the spring 53 keeps this hooked end of the rod against the curved recess 55 when the treadle is raised. When, however, the form of my invention illustrated in Figs. 1 to 4, inclusive, is employed, the curved or hooked end 382 is kept against the stop plate and positioned by the curved portion 55 thereof above the outer end of the lever arm 19 by the lever 39 and eccentric 40 and eccentric rod 41, which keeps said rod and said curved end raised when the setting device is not in operation.

The general operation of the machine hereinbefore specifically describedvis as follows: The operator rotates the rivet carrying mechanisms, together with the sleeve 8, around the cylindrical portion 7 of the column, until that rivet setting machine which contains the rivets of the size which he desires to use is in the position illustrated in Fig. 1. Then properly positioned, the locking lever 34 will spring into one of the notches 35, being caused so to do by the spring 37. The setting mechanism is now in position to be operated. The operator presses downwardlv upon the treadle 47 and as the locking lever 34 is sprung outwardly at its lower end, the hook 50 is disengaged from the tooth 52, so that the rod-49 does not lock the treadle 47 against downward movement. Said treadle 47 is, therefore, moved downwardly, thus lowering the lever 44 and throwing the clutch 43 into operative engagement with the shaft 42. Said shaft 42 then rotates and by means of the eccentric 40 and eccentric rod and strap 41, pushes upwardly on the outer end of the lever 39, rocking said lever and pulling downwardly upon the rod 38, thus bringing the hooked end 382 at the upper end of said rod into engagement with the roll 19 on the outer end of the adjacent arm 19. This rocks the lever 17 upon its pivot 18 and pushes the plunger 13 downwardly to lower the pocket 14 and to drive a rivet out of said pocket through the goods and clench the same against the anvil 12, it being understood that the goods are supported upon said anvil, 'as shown at 56 (Fig. 1). As soon as the rivet is driven into the goods, the plunger is drawn upwardly and the clutch is thrown out.

If it is desired to operate the machine by foot power the form of my invention illustrated in Fig. 5 is utilized and the treadle 47 is pushed downwardly by the operator, thus lowering the rod 38 which operates the setting mechanism, as hereinbefore described in relation to the form of my invention illustrated in Figs. 1 to 4, inclusive.

After the operator has used as many rivets as he desires from one of the settingn mechanisms, he pushes the locking lever 34 inwardly at its lower end, thus unlocking the sleeve from the column and rotates said sleeve, together with its rivet setting mechanisms, until he brings another rivet setting mechanism, with rivets thereon of the size desired into the position shown atthe left of Fig. 1, whereupon he releases the locking lever 34 and allows it to snap into one of the notches 35, thus locking the rivet setting mechanisms in position, and proceeds as hereinbefore described. It will be understood that when the notches 35 are out of alinement with the upper end of the locking lever 34, the upper end of said lever will ride against the periphery of the flange 36 and will hold the tooth 52 beneath the hook 50, so that the treadle cannot be operated.

It will be noted that by the construction hereinbefore set forth the hooked end 382 of the rod 38 is held in position against the stop plate 54, wit-h the lower end of said hooked end raised suiiiciently to clear the rolls upon the outer ends of the lever arms 19 when the sleeve 8 and the rivet setting mechanisms are rotated from one position to another.
