SPECIFICATION forming part of Letters Patent No. 411,835, dated October 1, 1889. Application filed February 23, 1889. Serial No. 300,859. (No model.)

To all whom it may concern: 7 the nail-holes in the adj ust. ble sections under Be it known that I, JOSEPH HORACE POPE, all adjustments of the latter. These objects a citizen of the United States, and a resident I accomplish by the construction and combiof Brockton, in the county of Plymouth and nation of devices hereinafter described and State of Massachusetts, have invented new claimed. 55

The objects of my invention are to avoid make a series of vertical slotted perforations 5 the foregoing objections and provide a secaa,oorresponding to the perforations b and 5 tional nail-die wherein each section has a se- 0 in the upper and lower adjustable dies, ries of nail-holes and the sections can be acand said middle die has also aseries of slotted curately adjusted and locked in their adjusted vertical perforations a ct", corresponding to position relatively to a stationary die-plate the breast-nail perforations b" c in the up- J 50 having a series of slots which register with per and lower adjustable dies 1) and c, as I shown. The said slotted perforations a and a" in the middle die are preferably made curved with radii, having the axis of the tube (1 as a center, so as to permit the nails to be driven through the perforations in the said upper, middle, andlower dies during the various adjustments of the said upper and lower dies. The upper and lower dies 1) c are connected to the middle die with freedom of lateral adjustments, preferably by means of setscrews 6 e passing loosely through perforations in. the upper die I) and screwed into screw-threaded perforations in the lower die 0. Where said screws pass through the middle die a, I prefer to surround them with sleeves e e, as shown in Figs. 2 and 3; but this is not essential.

a a are slotted perforations in the'middle die a, through' which the screws e'e or their sleevese e pass loosely, so as to permit of the free adjustment of said upper and lower dies relative to the stationary middle die a.

The upper and lower dies 6' o b c are preferably' adj usted ina positive manner by the following mechanism:

In a" bearing so", made in one piece with or suitably secured to the middle die a, is journaled the reduced portion f of the adjustingscrew F, which is provided with right and left handed screw threads f and f", as shown, which screw threads are screwed through the correspondingly-threaded nuts h and h,pivoted in bearings 17 0 secured to or made in one piece with the said respect ive upper and lower adjustable dies 1) and c, as shown in Figs. 1, 2, 3, and 5. Thus it will be seen that the dies b b and c 0 may be adjusted in a lateral direction to and from each other, according to the size of the heel that is to be nailed, simply by turning the screw F a little to the right or left, as the case may be; and, further, that the said movable dieplates' 1) c are after adjustment locked or held in fixed positions relatively to each other, while the slots in the stationary die-plate a sisting of a middle stationary die-plate hav- -inga series of slots, movable top and bottom die-plates each having a series of nail-holes, respectively, coincident with the slots, and

adjusting and holding devices for adjusting the movable die-plates and holding them in fixed positions relative to each other, said slots of the stationary die-plate registering with the nail-holesin the movable die-plates under all adjustments of the latter, substantially as described.

2. A nail-die for a h'eelingmachi-ne, consisting of a middle stationary die-plate-h'aving a series-ofslots, a series of movable top and bottom die-plates arranged uponeach' side of the stationary die-plate and each ha'V- ing' a series of nail-holes and adjusting and holding devices for simultaneously adjusting the movabl'edie-plates and holding them in fixed positions" relatively to' each other, stantially as described. 7 v f 3.- The improved nail-die,as-described,- consisting of the stationary slotted middle part a, and the upper and lower perforatedexpansive dies 1)" b c c, pivoted to a tube d, secured to said middle part, combined with the setscrews e e, for holding said middle" and expansive dies together, and the right-and-lefthanded screw F, journal'ed in bearing on the middle die a and working in nuts pivoted to the expansive dies 6 b c c, substantially as and for the purpose set forth.-

In testimony whereof I have signed my name to this specification, in the presence of twosubscribing witnesses, on this 26th day of J anuary, A. D. 1889. v j
