RIVETING AND PUNGI -IING MACHINE.

Specification of Letters Patent.

Patented J line 3, 1-919.

Application filed April 5, 1917. Serial No. 160,298.

To all whom it may concern:

Be it known that I, FRANK Y. PEARNE, a citizen of the United States of America, and residing in Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Riveting and Punching Machines, of which the following is a specification.

This invention relates to punc 'ing and riveting machines and more particularly to what are commonly called round seamers or machines that rivet together sec-' tions of riveted pipe, and the principal ob ject is to provide a round seamer that will- 1 e. p ft is a still further object to provide a round seamer with a plurality of electrical mechanisms that cooperate with the posi tively acting parts to perform the foot controlled operations.

In the drawings accompanying fication,

Figure this speci- 1 is a front elevation of a seamer having a stake of the usual length, with the main features of the invention.

Fig. 2 is an end elevation of Fig. 1 viewed from the right.

Fig. 3 1s a front elevatlon on the same scale as Fig. applied to a lengthened stake capable of carrying a section of pipe to twelve feet in length, the pipe on the position for riveting.

Fig. -1 is an end elevation of Fig. 3 viewed from the right side, partly in section, vertically broken.

Fig. 5 is also from the other an end elevation viewed end the parts being open for the reception of a section in this and 1 showing the invention as same being 1n Fig. 4, the drive of individual type being clearly shown in the latter view.

Fig. 6 is a detail in elevation of the pawl mechanism, the cams and bearing being in section.

Fig. 7 is an end view of the above, the bearing being removed to clearly show the engagement of the pawl.

Fig. 8 is an elevation of the pawl controlling sleeve, viewed from the inside or engaging face.

Fig. 9 is an elevation of the riveting cam in the same position as Fig. 3.

Fig. 10 is a plan viewed from the under side of the walking beams partly in sec tlOIll to clearly show the fastening means, anc

Fig 11 is an elevation of the heads that engage in the recesses of either end of the beams.

Other round seamers require cooperation of the hands, even where a foot control is used, since the tools have to be shifted in the common single head by hand, so that long sections of pipe cannot be easily and cheaply handled, and this invention is especially adapted to round seam the long sections formed on the straight seamer invented by me, and the subject matter of an application now pending in the U. S. Patent Office filed J an. 29, 1917, and serially numbered 145,801.

More specifically in the drawings, nu-

merals are used to designate the parts, 5'

representing a base preferably of concrete in which are embedded the parallel and vertically disposed I beams 6-6 providing a support for the short stake 7, secured in a flanged seat 8, the flanges 9 being provided with elongated holes through which the bolts 10 pass to secure the same to the beams adjustably.

To control the adjustment, to properly aline the dies, screws 11 are threaded into the straps 12 secured to the beams 6-, these screws bearing on The stake 7 is provided near its outer end with the dies 15 and 16 over which vertically reciprocate the tools, namely, a punch 17 and a combined lap layer and riveter 18, which are carried by their respective tool holders 19 and 20. The combined tool 18, acting as a riveter drives the rivets the edges of the flanges 9.

also for the shafts 42 that placed in the seam from the top, in common manner, to head against the anvil-die 16,

the lower end of the tool being cupped as shown in Fig. 4.

These tool holders are of a general cyllndrical form and are adapted to be reciprocated and guided in vertically disposed bores in a head formed by a plate 21 and the head 22 of a separately cast frame 23, this hollow frame being of sufficient weight but not necessarily as massive as the usual one piece frame, and the standard 1s provided with abase 24.

The punching tool holder 19 is a simple cylindrical slide, having a threaded lower end with a nut to secure the punch in the usual manner, the other being preferably formed of a sleeve 20 interiorly threaded, right and left handed so that the lap layer 18 with its left hand threaded shank 25, provided with a key 26 that fits within a keyway in the right hand threaded shank 27; may be capable of adjustment, by turning the sleeve 20, by means of the knurled boss 28.

The upper end of the shank member 27 V is swelled above the sleeve 20 to fit the guideway in the head 22, being reduced above this point to form the neck to which the cylindrical head 29 is secured, this latter belng embraced by a socket formed in the two part walking beam 30, that is adapted to reciprocate this too-l.

The punching member is with a head 29, but has its walking beam 31, this and the beam 30 being preferably in contact on their inner faces, and mounted loosely on the same shaft 32, which has bearings in the main frame at 33, that are so placed that they form retaining guides and bearings for the outer faces of the beams 30 and 31.

To reciprocate these beams at the proper times, a short shaft 34 is provided that has keyed thereon a large gear 35 which in turn is geared with a pinion 36 keyed to the shaft of a motor 37 mounted on a shelf secured to the main frame 23, and whereby the shaft 34 is driven continuously.

Mounted on the shaft 34 and in line with the beams are two eccentrics 38 and 39, each of which is surrounded with an eccentric strap 40, that are in turn connected to heads 41, embraced in sockets formed in the opposite ends of the beams from the sockets for the heads 29.

The shaft 34 has a boss or enlarged portion on which the eccentrics are loosely mounted, these bosses serving as bearings connect and form pivots for the pawls 43 and 44, mounted on either side of the bearings for the shaft 34,

also provided the outer pawl being. narrow and adapted to be operated by a clutch member normally held in contact'therewith and-thus hold the own reciprocating wide cam engaging pawl 43 from engage ment with the tooth cut in the hardened insert 45 in the eccentrlc, a spring 46 normally tending to force the pawl onto engagement.

The clutch member or rather pawl retainer 48 is freely mounted on the reduced ends of the shaft 34 and each has a recess cut on its inner face as shown inFig, 8, 'consls'ting of an inner annular groove wlth a periphery 49 and a shorter cam are 50, that brought onto or over the pawl 43 will throw the pawl into the annular groove and disengage the pawl 44 and allow the eccentrics and their beams to come to rest.

The retainer 48 has a pair of cylindrical studs 51 on its outer periphery which are engaged by the yoke 52 on a rocker arm 53' pivoted in a bracket 54 on the main frame, an arm 55 secured to the pivot pin of the crank, being under the tension of a spring 56, surrounding the lift rod 57, this spring bearing against a finger on the frame and being adjustable to normally keep the retainer in engagement and releasing the pawls.

'The lift rod is connected to a foot lever 58 through a bell crank pivoted to the outside of the frame, by a rod 61 which is ad justably secured to the arm 62 of the foot lever. The lift rod forthe beam 31 is designated 63 and is connected to the foot lever 64 through similar connections to operate the eccentric 39'of the beam 31.

To accommodate the slight transverse movement of the beams, shaft 32 are slightly elongated as shown in Fig. 4, and to take up any slack in the tool carrying members and lift this end of the beam to'its highest position, elbows 65 are provided on the upper end of each tool memthe bearings on the bar to receive the tension of a spring 66 lo cated so as to press upwardly from a socket in the head 22.

To provide for seaming a series of short connected sections, or one long section twelve feet in length, the stake is preferably formed up of a flanged sleeve support 70 secured to the I beams 66, a pipe or steel cylinder 71 being forced on the sleeve and supporting at its outer end the channeled casting 72, one channel being for the riveting block 74' and a passage way fo its rod, and a lower sage for the rod 75 secured to the bridging block 76 carried on an inclined slide 77 on the outer and lower part of the casting.

pas-

These punching and lap laying. members are operated by the built upbeams-3O and 31 previously described mounted on the frame 23, the parts of the beams being heldu spring 87 taking the thrust, and the spring 88- returning the lever when released.

On each rod 86 is an adjustable contact carrying member, having" spring" contacts 89 and 90; which are adapted to make contact successively with contact fingers 91, 92*

mounted in parallel position 011 the inside of the frame, the first mentioned being adapted to close the circuit from a battery or other sourceof electrical energy 93 with: a solenoid 9i, that through the connections to be described later, slides the bridging block 76- to: draw the same in: contact with the pipe,

to solenoid 95, contactto energize the solenoid draw up, the core- 96 connected to the bell crank 97 todraw inwardly the block 98' under the slide 99, this latter supporting the threaded stem support 1000f the pivoted saddle 101. A; nut 102 is threaded on the stem and key stem holds the parts in operative relation.

The block 98 is slidably mounted on a grooved and pivoted lever l Ohthe other end: of'whi'ch is resiliently supported by the leaf springs 105',- actin-g as a: safety device topre vent injury to the tools underaccidental conditions.

As the outer arm 97 raises, the rod 84 is drawnforward by the continued: depression of the foot lever to engagethe hook 106 with. the cross rod 107 on the crank, to lift the rod and release the pawl connections to operate the beam and reciprocate the tools in the proper timing;

The bridging block is formed. preferably of a sliding base 76 connected to the operating mechanism by the rod 75, and a removable block 108' held by screws, a number of these blocks 168' being provided, to form the seat for various diameters of pipe. The rod 75 is connected at its opposite end to a bell cranklever 109', the upper arm of which is provided with a: bore to receive the rod, and form a bearing for aspring 116 acting as a buffer;

The other end of the crank arm pivoted at 111: is connected with the core of the solenoid 94:, this solenoid. being connected and immediately this is set, the other contacts 90, 92,- controlling the circuit 103 sliding in a keyway in the ing rod= 11 i from the arm: 115 of the lever 112. to a bell= crank 116 pivoted on the frame 6, the other end of this crank being connectedby a rod: 117; to the rocking arm of a yoked member similar tot-hat described for the walking beams, the clutch sleeve being designated 119- and the continuously driven gear is driven by a. pinion 121 on; the end of the main" shaft 122:

The gear 120 and the mechanism: connected therewith are free on the shaft 123, flanged and provided with hearings in the frame nuinlbered 12 k on the frame 6, and keyed to this shaft is the cam 125 engaging with a roller 126 mounted in: a gimbaled frame 12:7 thisframe being supported in the yokes 128 of the pivoted member provided with: the: spaced arms 129,.to allow movement of the rod across which arms 129 is the pin 130 to which. the end of the rod. 13-1 is secured; the other end being adjustably connected, with the riveting block M, bearing on a hardened plate in the casing.
