ASPIECIIFIGATION forming part of Letters Patent No. 472,882, dated April 12,1892.

Application filed December l, 1891. Serial No. l13,717. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. HOUGHTON, a citizen of the United States of America, residing iuNorthumberland, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in Nail-Machines, of which the following is a s pccilication.

My invention has relation to improvements to in machines for making pointed nails from a common rolled plate; and the object is to provide improved means for laterally moving the point-cuttin g dies to shear and clean the point on thenail after the direct contact of the dies. The invention consists in details of construction, as hereinafterspecitied, and particularly pointed out in the claims.

I have fully and clearly illustrated my invention in the accompanying drawings, where' zo m- Figure 1 is a plan view of a nail-machine having my invention applied, certain parts of the machine being removed and others shown sectionized. Fig. 2 is a side View of the point- 2 5 cutting bed-die. Fig. 3 is a side view of the stationary part of the liner on the bed of the machine. Fig. 4 is a top plan view of the same. Fig. 5 is a plan view of the expanding part of the liner for the point-cutting bed-die.

3o Fig. 6 is a view of these parts united, partly in section. Fig. 7 is a side view of the pointcutting moving die. Fig. 8 is a side View of the stationary part of the expanding liner. Fig. 9 is a view from the reverse side shown in Fig. 8. Fig. l0 is a top view of the movable part of the expanding liner for the moving point-cutting die. Fig. 11 is a side view of the same; and Fig. I2 is a view showin g the lparts illustrated in Figs. 8 and 10 in opera- 4o tive relation, the stationary part being shown in section. Fig. 13 is a detail side view of the returning-spring. y

In the drawings, A designates the bed of the machine, B the gripping-lever, and O the cutting-jaw, which is broken oft to disclose the relation Vof the respective dies. The respective gripping-dies l 2 are of the usual construction and arranged and secured in position by the usual means, substantially as shown, land the opposing point-cutting dies are designated by a, and b.

The primary element of my present invention is an expanding liner interposed between the gripping-dies and the laterally-movable point-cutting dies for the purpose of moving the latter elements outward when inopera-- tive union on the nail-blank while that is held by the gripping-dies. With this in view I make the liners in two parts, formed so that when one part is moved longitudinally it will 6.o be moved laterally to push the point-cutting die outward. v

In thedrawings, especially Figs. 8 to 10, in elusive, 3 designates the stationary part of au expanding-liner adapted for the point-cuttin g die on the gripping-lever. This part has a channel 4 formed in its side extending for the greater part of its length, and in the upper Wall of this channel has a recess or cutaway portion 5. On the opposite side ot' the 7o part leading from the other end is a channel 6, an opening 7 being made through the part between the inner terminations of the channels,in which an extension on the other part projects, substantially as shown. The stand- 7 5 ing part 8 has the outer end 9, inclined outward to engage with a corresponding incline on the other part. On the inner portion is a flange 10, serving as a keeper and abutting piece for the point-cutting die and also as an abutting 8o flange to hold the liner in position and so that the gripping-die can be irmlyclamped against the liner in` itsv seat. 1l designates the movable part of this expanding liner, hav- -ing a stem 12 to fit the channel 4of the other 85 part and a side-extended piece 13 to engage through the opening 7 and'channel 6. In the side of this part is a recess 14, Ahaving an inclined end 15, which engages the incline 9 on lthe other part. This part 1l is given limited 9o longitudinal movement in its seat in the other part, in order that when moved the contact of the inclines will throw the opposite face or side beyond the face of the other part, and since it has its bearing against the face of the point-cutting die, that element will be moved also. The part llis moved positively in the direction to expand the liner by means of a projecting stud 16, contacting with the rear face of the cutting-jaw or properly conrco nected to some other moving part of the machine. The part 1l is returned to its normal position by means of a spring 17, arranged at the rear of the portion B, substantially as shown.

The same principle of expansion of the liner is carried into effect in respect to the operation of moving the point-cutting bed-die, the construction being specially illustrated in detail inFigs. 4, 5, and 6, and wherein 18 designates the stationary part of the liner, having a channel 19 in one side terminating in an inclined end 2O and formed with an opening 2l. At the rear end the metal is cut away, as at 22, to form a seat for the abutting piece on the movable portion of the liner, and from theside of the liner is a flange 23, which rests in a recess in the pointcutting die andv extends into and rests in a recess 24, formed in the inner face of the side wall of the bed. 25 designates the. expanding portion of the liner, consisting of a stem 26, terminating in an inclined end 27 io engage the incline of the other part and having a broad side extension 2S to engage in lthe opening of the other part. At the rear end is an abutting piece 29 to engage in the recess or seat 22 of the other part, as in the other-described construction for the point-(nuttin g moving die. This part 25 isthrown outward when pushed against the incline of the other part and at the same time moves the point-cutting die outward. Any proper leverage may be ern.,- ployed to expand this liner. I have shown a bar journaled in the bed and provided with a lug 3l, projecting up through the loor of the bed and engaging against the rear end of the movable portion of the, liner. At the outer end of the bar 30 is an arm 32, having its end connected to some reciprocating part of t-he machine. I have shown it as being connected to the cutting-jaw by a rod 33.

To return the point-cutting dies to their inner and normal relation after being moved out by the liners, I provide a spring 34, bent at right angles, having its vertical arm secured to the frame of the machine (see Figs. l and 13) and its horizontal arm broadened at the end, as at 35, and arranged to bear and push against the poin t-cutting dies, as shown in the drawings. I

The operation is as follows: The nail-blank being severed and pushed down to the dies, it is there gripped, and While so held the cutting-jaw moves upward and through the connections eventually moves the expanding liuers'by moving the parts in opposite directions, and thus moving the point-cutting dies outward while the dies are still gripping the nail, thus cleaning and shearing the point.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. In a nail-cutting machine, the combina-v tion, with laterally-movable point-cutting dies, of expanding liners arranged adjacent to the dies and means for expanding the liners to move the dies outward, substantially as described.

2. In a nail-cutting machine, the combination, with laterally-movable pointcutting dies, of expanding liners arranged adjacent to the dies, said expanding liners consisting of a stationary part and a part having limited and longitudinal and lateral movement, and means for moving the movable part, substantially as described.

3. In a nail-cutting machine, the combina-v tion of laterally-movable point-cutting dies andtwo-part'liners adjacent to the dies, said parts having inclined contacting surfaces, whereby when one of the parts is moved longitudinally it is also moved laterally, substantially as and for the purposes specified.

4. The combination, with the laterallymovable point-cutting dies, of expanding liners to push vthe dies outward, means to expand the liners, and a spring to return the dies inward, substantially as described.

5. The expanding liner for a nail-cutting machine, consisting of the part having a channel in its side and an inclined end piece at the end of the channel and the part formed to lit the channel of the otherpart 4and having a notch having an inclined end to engage the incline of the otherpart, and a projection to engage a moving part of themachine, substantially as and for the purpose specified.

6. The expanding liner for a nail-machine,

4consisting of the part having a channel terminating in an inclined end and formed with a side-abutting flange and keeper and an opening, and the part formed to tit the channel and opening of the other part and having an inclined end to engage the incline of they other part, substantially as described.

7. The combination, with the gripping-die and the point-cutting die of a nail-machine, of a liner interposed between the dies and formed with a side-extending flange to set over the point-cutting die and against an abutting surface, whereby the pressure of the gripping-die is against the liner and not against the point-cutting die,'substantially as described.

8. The combination, with a laterally-movable point-cutting die of a nail-machine, of a stationary liner adjacent to the die and a movable piece between the liner and the die, whereby the die may be moved outward, and means for moving the movable piece, substantially as described.
