VILLIAM VVATERMAN MOOALLIP, OF COLUMBUS, OHIO.

FENCE-RIVETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 403,950, dated May 28, 1889.

Application filed March 16, 1889. Serial No. 303,585. (No model.)

To all whom, it may cmwcrn:

Be it known that 1, WILLIAM WATERMAN MCOALLIP, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Riveting-Machines, of which the following is a specification.

My invention relates to improvements in riveting-machines especially adapted for riveting pickets to the rails or bars of an iron fence; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a riveting-machine embodying my improvements, showing the manner of using the same. Fig. 2 is a top plan view. Fig. 3 is a crosssection taken on the line at a: of Fig. 2. Fig. 4 is a detail cross-section on the line 3 y of Fig. 2.

On a bench or frame, A, which has suitable supporting-legs, B, is bolted a plate, 0, having a pair of standards, D, the latter forming the bearings for the pivotal bolt or trunnions E of a beam, F. To one end of the latter is secured a hammer-head, G, with its lower end fashioned as shown in Fig. 3. The front end of the hammer-beam moves between a pair of vertical guides, H H, and suitable mechanism of any well-known kind may be employed Such mechanism, however, has not been shown in the drawings,

inasmuch as it forms no part of the present invention. In rear of the fulcrum of the hammer-beam and suitably connected with the latter is arranged a coiled spring, the expansive force of which aids the hammer in delivering its blows.

On the front end of the frame A is arranged a guide-frame, which comprises a pair of vertical bars, 0, having vertical slots P. To the upper ends of the said bars are attached supporting-brackets R, over which the metallic fence bar or rail a is adapted to be moved. Said fence bar or rail is of the usual construe tion and is rolled with the usual longitudinal groove, b, and is provided with the usual openings, 0, arranged at suitable distances apart and adapted to receive the tenoned ends of the rods cl.

A pair of guide-bars, S, are secured at reguthe latter to the rail a.

lar distances apart by blocks inserted in their ends, and adj Listing-bolts T pass through the ends of said bars and are adapted to move in the slots P. The function of the said bars is to steady and retain the rods d against lateral movement while the same are being riveted in the openings 0.

Under the guide-bars S and in Vertical alignment with the hammer is a block, U, which has a vertical opening adapted to receive the lower end of the spindle of a diereceiver, V. A set screw, WV, works in a threaded opening in a collar, X, on the upper side of the block and engages the die-receiver, serving to retain the latter at the correct vertical adjustment. The upper end of the diereceiver is dovetailed to receive the transversely-slidin g die Y, the latter having an opening or recess, Z, which may be placed a suitable distance out of alignment vertically with the hammer, as indicated in Fig. 1. Said die-is retained in place in the die-receiver by a set-screw, A, and may be removed and reversed or replaced by another when desirable.

A horizontal supporting-rail, B, has one end attached to one of the standards 0, and has its opposite end supported by a suitable standard, 0, and on the said rail travels a grooved wheel, 13*, from the pivots or axis of which is suspended a carriereframe, E, the latter being adapted to support one end of the rail a, and hence enable the latter to be easily moved on the bracket R, so that each opening 0 will successively register with the hammer.

The operation of my invention is as follows: A workman inserts each bar d in succession with its lower end in the die and its upper tenoned end in one of the openings 0, thereby arranging the said bar d at an angle other than a right angle to the rail or bar a, as shown in Fig. 1. The hammer is operated, and the same serves to swage the tenoned end of the bar (1, and thereby securely fasten The bars (1 from the center to the ends of the rail a are inclined in opposite directions, as indicated in Fig. 1, and when the said rods (1 are arranged parallel with each other, which is done when the other fence-rails are placed in position thereon, the bottom rail, a, will become arched, as is apreceiver, all in combination, substantially as parent, and thereby adapted to withstand a greater vertical strain, and thus prevent the fence panels from sagging.

Having thus described my invention, I claim- 1. In a machine for riveting iron fences, the combination of the hammer, the die arranged out of vertical alignmenttherewith, the guideframe to support one end of the fence bar or rail, and the traveling carrier to support the other end thereof, substantially as described.

2. The combination, in an iron-fence-rivet ing machine, with the hammer, of the supporting-frame having the armor bracket R, for the purpose set forth, the guide-bars S, vertically adjustable on said frame, and the die,substantially as described.

3. -;'lhe-combination,'with the hammer, of;

the block U,'arranged below the same, the{ die-receiver supportedin the block, and the die fitted adj'ustably in a recess in the upperi; end of the receiver, substantiallyas describedj 4. The block U, having the vertical recess; and collar X, with set-screw W, the die-re-i ceiverhaving the spindles'in said opening or; recess and; engaged by the set-screw, "and the; dieflfitted in the recess in the upper end of the? described. 1 j

5. The rail'ct and the bars or rods d, with one end secured thereto, said rods being inin said recess and having an opening or reccss in its upper face, and a fastening-screw, substantially-as set forth.

8. The combination of the hammer, the anvil havinga dovetailed recess, the trans verselyadjustable die having a recess in its upper-face, and means for suspending and carrying the fence-rail transversely under the hammer-and for guiding the pickets,=substantially as set forth.

In testimony that'l claim the foregoing as my own I h-avehereto affixed my signature in .presence of two'witnesses.
