NAIL-PLATE FEEDER.

SPECIFICATION forming part of Letters Patent No. 315,019, dated April 7, 1885.

' Application filed May 17, 1884.

.To all whom z't may concerm,

Be itknown that I, JOHN C. GOULD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Nail-Plate Feeders, of which the following is a specification.

This invention relates to the construction of the parts of nail-plate feeders, whereby the barrel is supported and operated, and particularly to the kind of feeder shown in the Letters Patent to me of January 22, 1884, No. 292,299. As heretofore made there has been great difticulty in adjusting these parts when it was desired to change the character of the work to be done,or when the parts were out of adjustment and it was desired to properly position them. To ease this adjustment has been the principal object of the present invent-ion, which consists in the combination, in a nailplate feeder, of the barrel and a standard for the same adjustable upon' a circular line whereof the cutting-point of the machine is the center, and whereby the standard may be adjusted without destroying the proper position of the nose of the barrel at the knives.

The invention further consists in the novel construction and combinations of the'several parts, as hereinafter fully set forth.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a side View of the parts of the machine to which my invention relates. Fig. 2 is a central longitudinal vertical section of the same. Fig. 3 is a rear view. Figs. 4 and 5 are horizontal sections on the lines 4 4 and 5 5, respectively, of Fig. 3. Fig. 6 is a detail section of one of the supportingbrackets. Fig. 7 is a section on line 7 7 of Fig. l.

In the drawings, A represents the block whereon the stationary knife is supported, and A the moving knife.

Attached to the block A are L-shaped brackets B B, which may be adjustable vertically. The horizontal portions of these brackets are slotted at b, and resting on such horizontal portions, with depending extensions entering said slots, are blocks B. Said blocks are secured by screw-bolts b', passing up from below into the depending extensions, the heads of (N0 model.)

such bolts spanning the slots. These blocks support the screw-pivots C, upon which the saddle G/ and the parts borne thereby oscillate.

It will be noticed that by the use of the L- brackets and the adjustable bearing-blocks I am enabled to adj ust either or both ends of the saddle horizontally withoutloosening the pivot-screws or otherwise destroying its vertical position. This could not be done with-the construction shown in the previous machine.

The saddle C in my improved machine passes below the oscillating rod H, instead of above it, while the foot D and the barrel-supporting standard D', which in vmy said patent were in one piece, I now make in two pieces, for reasons now to appear. The foot D swings upon the pivotal screws d, passing into the same from the saddle C', and the standard is adj ustably bolted to the rounded vertical faces d of the foot by bolts passing through elongated openings iu the standard, as shown, the

lower extremity of the standard being also correspondingly rounded, as shown. This rounded line, along which the standard is moved in adjustment, is the circumferential line of a circle having its center at or near the point at which the nails are severed from the plate. This center is indicated at zo, and enables me to adjust the standard and barrel laterally in either direction without moving the nose of the barrel from its position. The ball H upon the end of the oscillating rod His centered in a socket in the Haring head of a pin, H2, passing through the segment E and supported in the standard D. The teeth upon the segment E mesh with the teeth upon the barrel D2, and give it the customary half-revolution, the segment being actuated to this duty by the armll, secured in the head of the rod H, the upper point of the arm entering between the projection f and the adjustable angle-piecef, bolted to the segment. By thus communicating power to the segment near its center, instead of at the point, at which it was done in my former machine, friction is lessened to a very considerable extent! The brackets B B are each provided with downward extensions b3 b3, through which passes the bolt B2, which draws the brackets together.

The holding-springs K, by which the nailplate is held, are secured to the nose of the IOO barrel by bolts 7c, and in'order to permit the use of springs ofthe Customary length with a Short nose of gentle taper I recess the body of the barrel at the proper places, so the rear ends of the springs may extend thereinto, as shown in Fig. 2. I thus economize in the length of the nose, and avoid the interference with the knife-bloek,\vhicl`l would resultif the :nose Were made so tapering as to permit the springs to extend outside of the barrel. The springs also act better than When set upon a Wider angle.

I claim- 1. The barrel and its standard D, the latter being adjustable along acircling line,as specified, and both barrel and standard swinging to and from the knives, inoombination With the saddle upon which the standard is supported, substantialty as described.

2. In a nail-plate feeder, the combination of the barrel, the standard D', and foot D, the standard being adjnstably secured vupon the foot, substantially as specified.

3. In a nail-plate feeder, the combination of the pivoted saddle, the foot pivoted in the saddle, the standard D', adjustable upon the foot, and the barrel and its operating-segment supported upon the standard, all combined and operating substantially as specified.

4. The combination, in a nail-plate feeder, of the foot D, the standard D', With the flaring head, pivotal pin H2, the ball H', and the segment E, substantially as specified.

5. The combination, in a nail-plate feeder, of the saddle and the parts borne thereby,with the L brackets, and the adjustable pivotblocks supported on such brackets, substantially as specified.

6. lThe Combination, in a nail-plate feeder, of the vibrating segment for operating the barrel and its actuating-arm, the latter being Connected to the segment at the point and in the manner shown.

7. In a nail-plate feeder, the barrel and its nose, inA combination with the springs, the barrel being recessed to receive the rear ends of the springs, substantially as specied.
