RIVET-STIICKING MACHINE.

SPECIFICATION forming part Of Letters Patent No. 602,139, dated April 12, 1898.

Application filed February 7, 1896. erial No. 578,362. (No model.)

One object of my invention is to avoid these difficulties.

Another object is to provide a small and inexpensive rivet-sticking machine of great effectiveness and of great ease and convenience of operation which will be completely automatic, so that the complete operation of sticking the rivet is the result of one complete movement of a treadle or other lever.

By using this machine the length of each joint of pipe is limited only by the width of sheet that can be had, and the operator at the same time he punches the rivet-hole can stick a rivet in the hole he has punched, thus saving a great deal of time in the manufacture of pipe. 7

The principle of my invention is applicable both for round seaming and for straight or long seaming.

In the machine as adapted for round seaming it is an object of myinvention to space the holes and guide the pipe so that the rivets will be set at uniform distance and the seam will be true.that is, the rivets will all be set in a plane at right angles to the pipe.

My invention comprises the rivet-sticking machine and the several parts and combinations hereinafter describedand claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a fragmental perspective view of a rivet-sticking machine embodying my invention asapplied for round seaming. Fig. 2 is a fragmental perspective view illustrating the application of my invention in a machine for straight seaming. is a crosssection cut through the stake, rivet-carrier, rivet-hole punch, and. rivet-hole-centering 1 pin of, the round seaming machine. The punch is not sectioned, and the pipe is shown in position with a rivetinserted through one rivet-hole and with another rivet-hole ready punched, so that the pipe is ready to be turned to remove the rivet from beneath the holecentering pin and to bring the other rivet hole above the carrier to receive a rivet. Fig. 4 is an enlarged fragmental detail on same line of section as Fig. 3, but shows the carrier in the position shown in Fig. 9. i Fig. 4 is an enlarged detail with carrier in the position shown in Fig. 3. Dotted lines show a rivet passing out. Fig. 5 is fragmentalelevation of the rear end of the machine. Fig. 6 is a fragmental elevation of the front end .Of the stake, with lower portions of the punch and the hole-centering pin. Fig. 7 is a perspective view of the machine. Fig. 8 is a fragmental sectional view of the stake. The section is taken along the midline of the rivetrunway. The rivets are shown in position in the runway, but not in section. In this view and in Figs. 1 and 3 the parts are shown in the positionv occupied when the machine is at rest and after the. pipe has. been turned to bring a rivet-hole into position to receive a rivet. The position of parts shown in this view is that which obtains both before the movement shown in solid lines in Fig. '9 and after that shown in dotted lines in the same figure. The pipe is shown only in Fig. 3. Fig. 9 is a fragmental section taken onthe same line as that of Fig. 8, butshowing the parts in position for the rivet-moving means to move the line of rivets, so as to push the end rivet onto the rivet-carrier. Dotted lines indicate the position of the parts when a farther movement of the slide has completed the operation of seating such rivet upon the rivet-carrier. The position thus shown in dotted lines is the one which obtains when the foot-lever which operates the machine is fully depressed,while the position shown in full lines is that which obtains at one moment of the downward movement of the foot-lever. Fig. :10 is a fragmental plan of the round-seaming machine, looking downupon the rivet-runway. Fig. 11 is a plan of the rivet-carrier and the clampingspring and block.

My newly-inventedrivet-sticking machine comprises the combination of the stake A, having a rivetrunway B therealong, means for'moving rivets along the runway, a rivet- IOO carrier 0, adapted and arranged for receiving the rivet from the end of such runway and moving it toward the face of the stake, and means for operating such carrier. The means shown for moving the rivets along the runway consist of a plunger or rivet-slide D, arranged at the rear end of the runway to reciprocate into and out of the runway across the mouth of a chute E, through which the rivets are fed into the end of the runway. The rivet slide or plunger D is operated by suitable means which I will hereinafter describe.

The means for operating the rivet-carrier consist of a suitable rivet-carrier block 0, provided with a slideway c, and the bent slide 0 arranged to play through the slideway to reciprocate the carrier block and the carrier C, which is mounted thereon. Suitable means are provided for operating the bent slide 0 and the means shown for this purpose consist in a reciprocating slide F, with which the carrier sIide O is connected by a suitable brace 0 This reciprocating slide F extends from end to end of the stake and is operative] y connected at its rear end with the rivet plunger or slide D and is also operatively connected with means arranged for reciprocating the slide F. Thestake A is provided with the transverse bore a for the carrier-block and is provided on one side with the slideway a, extending from the rear end to the front end of the stake across such crossbore a, and is also provided with the guideway a extending from the front endto and beyond the transverse bore to receive the bent slide 0 which is operatively connected with the carrier by suitable meansviz., the carrier-block to reciprocate the carrier. At the front end of the stake the slideway a is a round bore and at the cross-bore a and from there to the rear end of the stake such slideway is a channel. The round-seaming machine is provided with a rivet-hole punch G, arranged vertical, as With ordinary stakes, and the stake is provided with the ordinary bur-hole g, which, in the stake as shown, passes down through the transverse bore a, which serves as a guide for the rivet-carrier block 0, and such bore a is arranged at a suitable angle to such bur-hole, so that at the face of the stake the space between the rivet-carrier and the bur-hole will be equal to the distance desired between the rivets.

The rivet-carrier O is provided with a rivethead seat 2, which is flush with the floor b of the rivet-runway B when the carrier-block is in its retracted position, and is also provided with a rivet stop and guide 3, arranged to engage the stem of the rivet on the front side and upper side of the carrier-that is to say, upon the side of the carrier opposite the rivet-runway and upon the side of the carrier which is toward the rivet-hole punch.

II is a spring set stationary with relation to the stake at the under side of the path of the carrier and arranged to press upward toward the carrier in the direction of the rivethole punch. The outer edge of this spring is practically in the same plane with the rivetseat 2 of the carrier when the carrier is fully thrown out to stick a rivet. The rivet-seat 2 of the carrier and the rivet stop and guide 3 011 the upper side of the carrier opposite the spring are so arranged with relation to each other that when the rivet is seated upon the rivet-seat of the carrier and the carrier is in its retracted position the guide will engage the stern of the rivet, while the lower edge of the rivet-head projects beyond the lower side of the rivet-seat, so that when such carrier is in position and the rivet is pushed thereupon from the rivet-runway the rivet-head will be engaged by the rivet-clamping spring 11, as shown in Fig. 4E, and the rivet willbe clamped between the spring and the upper stop and guide 3 on the carrier until the carrier has been moved sufficiently toward the face of the stake to insert the rivet into the rivet-hole, and when this is done the rivet-seat is flush with the top of the spring and the rivet is above and therefore released from the spring H. The rivet-clamping spring His fastened to a spring-holding block h, which is seated in the stake and secured'by a screw h.

The lower portion of the rivet-runway is wider than the head of the rivet, and guideways Z) b are arranged one along each side of the runway to engage the stems of the rivets and hold them in a right line and direct them to and onto the rivet-carrier when the carrier is retracted-that is to say, in its lowest position.

I is a rivet-guide fastened to the stake and arranged above the carrier to allow the stem of the rivet to pass through such guide when the carrier is moved downward. The guide opens downward away from the punch and is closed at its upper end, and the under side of the guide is provided with a beveled face 1', against which the end of the rivet may strike when the rivet is pushed outward by the carrier. and the upper part of the guide 3 of the carrier are arranged in such relation that when the rivet clamped by the spring is pushed upward by the carrier its end will first engage the beveled face i of the guide and will thereby be moved downward slightly. The upper end of the gnidewayi of the guide I is closed and is-in exact position to register with the upper edge of the centering-pin and the upper edge of the rivet-hole which has been punched at the moment the pipe is in position for the succeeding rivet-hole to be punched, so that when'the pipe is in position for the succeeding hole to be punched the operation of the carrier will serve to force the rivet into the hole which has been punched.

J is a rivet support arranged along and beneath the rivet-guide and extending downward, as shown in Fig. 3, to carry the rivet below the point where it would drop out of its hole after being inserted thereinto-that This beveled face, the spring,

is to say, to the position in which the stem of the rivet will be horizontal or inverted.

K indicates the rivet-hole-centering pin adapted and arranged to be movedtoward and from the stake in the extended path of the rivet-carrier. It reciprocates axially. to enter the rivet-hole and to be withdrawn therefrom. indicates the spring which forces this pin toward the stake, and when the pipe is placed upon the stake the pin K is springpressed against the pipe, so that when a rivethole has been punched by the punch G and the pipe turned the pipeP will be engaged by the pin K until the upper edge of the rivethole registers with the upper end of the rivetguideway 2' and at that instant the springpressed rivet-hole-centering pin K will be forced into such rivet-hole, thus stopping therotation of the pipe and holding the pipe in position for another rivet-hole to be punched, and also in position for the insertion of the rivet from beneath. Then when the machine is operated to force the rivet up into the rivethole in the pipe the end of the rivet-stem will engage the centering-pin and carry it up out of the rivet-hole and thus leave the pipe free to be again turned after the succeeding rivet- 'hole has been punched. When the pipe is thus turned, it slides the rivet off from the carrier and out from under the centering-pin (which immediately engages the surface 'of the pipe ready to enter the next rivet-hole when it comes under it) and along the guide and over the rivet-spring and the rivet-support until the V succeeding rivet-hole comes beneath the centering-pin. Then the pin enters such'hole and the operation just described is repeated.

L indicates a catch for holding the centering-pin away from the stake when it is desired to remove the pipe from the stake or place thereupon a joint of pipe.

M is a rocking shaft provided with thefootlever m at the front end of the stake and extending back to the rear of the stake, where it is connected by suitable means 4, 5, 6, 7, and 8 with the reciprocating slide F. A spring Nis arranged to hold the rocking shaft in position to hold the slide F fully retracted to the left, and thus to hold the carrier 0 in its raised position, such as shown in Figs. 3, 4.,

and 8. The downward movement of the footlever against the action of this spring throws the slide F to the right from the position shown in Fig. 8 andinto the position indicated in solid lines in Fig. 9, thus to retract the carrier so as to bring its seat flush with the floor of the runway, as shown in Figs. 4 and 9, and a further and final downward movement of i the foot-lever operates the slide or plunger D sufficiently to force the rivets forward and seat the front rivet onto the carrier. i

In the operation of the machine the chute E will set one rivet at a time in position to enter the runway B, and at each forwardmovement of the plunger D this rivet is carried forward, this carrying the line of rivets 0 forward and seating the front or end rivet, as above stated, upon the carrier. The footlever is arranged so that it does not complete its downward movement until the plunger D a hammer and punches a rivet-hole in the pipes. Then he turns the pipes to the left until stopped by the rivet-hole-centering pin K,

which enters the rivet-hole as soon as it comes beneath it. The workman then strikes-the rivet-hole punch again and at the same movement operates the foot-lever m with his foot,

Then he relieves the foot-lever and'allows the spring N to bring the machine to its first or normal position, and at the same time he turns the pipe and from thence the operation is the same as that just described until the circle of rivets is complete. Then the pipe is withdrawn sufficiently to allow the workman to hammer the rivets and finish the joint. In the straight-seam machine the rivet-hole punch G and the rivet-hole-centering pin K are arranged in line parallel with the stake,

and in sticking rivets for straight seaming the operation is the same as that above described, except that instead of turning the pipe the workman pushes the pipe onto the thus sticking a rivet in the first rivet-hole.

stake the space between two rivet-holes each time a hole is punched and a rivet stuck.

J indicates a rivet rest and shield above the rivet-runway B of the straight-seam machine.

In the straight-seam machine the rivetguide 1 extends along instead of across the stake,'and the rivet-support J is dispensed with, its office being performed by the rivetrestJC' In both the round and the straight, seammachines the punch and the rivet-hole-centering pin are arranged in the plane in which the seam is to be made. In the round seam this plane is at right angles, to the stake and in the straight seam it'is parallel with the stake.
