HORSESHOE-NAlL-FINISHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 358.904, dated March 8, 1887.
Application filed June 536, 1886.
To all whom it may concern:
Be it known that l, JOHN PETER WENNER` sTEN, a citizen of Sweden, residing at Chicago, in the county of Cook and State of Illi nois, have invented a certain new and useful Improvement in Horseshoe Nail- Finishing lliachinesofwhich the followingis a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to improvements in that class of horseshoe-nail-finishing machines in which the principal operative mechanism consists of a series of rolls in the surface of which is imprinted the form of the nail to be finished. rThese rolls, acting in pairs, receive the blank or rough nail and reduce it to the nished product.
My object is to improve this machine in some minor details, but principally to perfect that part in which the surplus metal is cut off and in which the point is formed.
In the drawings illustrat-ive of my invention, Figure l is a front elevation. Fig. 2 is a section on line x x of Fig. l. Fig.I 3 is a detailed plan view of the intermittent-feeding device. Fig. is a rear end elevation. Fig. 5 isa section on line Y Y of Fig. S. Fig. Gis a section on line Z Z. Fig. 7 is a plan view of the cutting-off and pointing roll. plan view ofthe upper rolls. Fig. 9 is a section of the channel-piece H. Fig. lOis a view of the finished nail and of the out olf refuse.
Similar letters refer to similar parts throughont the various views.
The frame A is provided with standards c and a', fitted with adjustable brasses to receive the several shafts B B B, journaled therein. 'These shafts are geared in pairs by the pinions b b b, and have a iixed rotative relation to cach other through the gears b b b. rThe train is actuated by the large gear b2, which in turn is given motion through the pinion b by the driving-pulley b".
On the rear ends of the upper pair of shafts B and B as shown in Figs. 4 and 5, are carried the roughing-rolls C and C, respectively. On the ends of the middle pair of shafts B and B are carried the iinishing-rolls D and D', re-

spectively. On the ends of the lower pair of 5o shafts B and B are carried the pointing-rolls E and E', respectively, all these rolls being ot' hardened steel.
Above the center of the upper rolls, C and hC', at the point at which they are tangent, is 55 the feeding-tube F. This tube is of sufficient length to receive several blanks one above the other, the blanks being of the form usual to this ciass of nails.
Ainger, f, as shown in Fig. 8, is pivoted at 6o f', and carries the projecting point f, having a motion within and through the slot at the bottom of the feedtube F. A retainingspring, f3, serves to hold this point in position to prevent the feeding of the blanks eX- cept at regular intervals, which are deter mined by the pins carried by the collar B on the shaft B. This collar is provided with a set-screw to permit oi accurate regulation of the time of dropping the blanks into the rolls below. rThese blanks are received by the rolls C and C while they are in the position as indicated by Fig. 5, and by their continued rotation the blank is swaged into the form of the die in their surface, the surplus metal serving to elongate the blank. From these rolls the rough nail passes through the channel of the gnidepiece G to the second pair of rolls, D and DI, being received by them while in the position indicated. These relative positions, it will be understood, are determined by the length of nail operated upon. Here the rough nail is finished with regard to its head and to the body. Surplus metal is cut oft' by the shearing action of the knife-edged, acting s 5 against the surface of the roll D'. Thence the unpointed nail passes into the channelpiece H. (Shown in enlarged section in Fig.
9.) Finger-springs 7L are insertedin this channel to guide accurately the nail into the re- 9o cesses of the pointingrolls below, into which the nail next passes. An enlarged view of these rolls is shown in Figs. 6 and 7, they being represented in the position at the time at which the nail is received. By the continued 9 5 rotation of the rolls the nail is seized between the points of the spring e of the roll E and the spring c of the roll E. Further rotation while the nail is in this secured position brings its end over the die-opening e2 ofthe roll E, into which it is forced by the eccentric faced punch e3. The shearing action of this punch against the dieedge of the opening e2 cuts off the surplus metal and leaves the pointed iinished nail, as shown in Fig. l0.
The roll E is recessed at r to allow the eut off waste S to lie within its circle until the rolls are turned sufficiently to free it, when it is forced from the V-shaped punch by the spring e4 and falls down. The nail has already dropped from the rolls, the point on which it rested, e5, being of such incline as to permit it to do so freely when it is forced from its bed by the spring e.
For convenience of construction and for other reasons the roll E is formed of two plates or parts, as represented, keyed together by the pinspp. The cutting-edges of the die can consequently be readily sharpened, and, by allowing space between the two parts ofthe roll when first made, wear can be taken up by bringing the two elements closer together. The roll E, for similar reasons, is constructed in three parts, keyed together by pins p' p. The middle element, E, need alone be of hardened steel, and the springs, if desired, can be secured to the other elements. The middle piece, being alone subject to strains, can thus be cheaply replaced in case of breaking. It is ordinarily of great difficulty in mechanism of this class to have the parts subject to strain stand77 It is consequently all-important to construct them so as to be easily and quickly replaced. I have described these rolls throughout as though constructed to produce but one nail at each revolution. They may be provided with as many die forms as desired. Those represented in the drawings have two sets of die forms in their surface, and consequently will produce two nails at each revolution. This number may be increased as is found desirable. As illustrated and described, the forniing ofthe nail is divided into two operationsd that of roughing and that of iinishing. These may be abridged and one pair of rolls perform both operations; but the preferable method is by the use of two pairs ol" rolls, as described.
Each nail-machine is provided with several sets of rolls, to allow of the production of different lengths and shapes of nails.
It is obvious that many equivalent devices can be used in the rolls E and E. Coil-springs, with suitable attachments, can be substituted for the at springs. The pins p p may be dispensed with. It is also unnecessary to construct the rolls in parts, although desirable. To prevent the springing of these rolls C and C', D and D', E and E one from the other by the pressure of the nail, the shafts B B B are produced beyond the rolls and wearing-collars placed thereon, against which shoes or bearing-pieces I I I are held and adjusted by the setscrews z' t' i, threaded in the flanges a of the main frame of the machine.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a horseshoe-nail machine, the combination of a pair of rolls, E E', geared to revolve together and toward each other above their axes, a V-shaped die-opening and a recess in one roll and a punch corresponding with said die-opening and a recess in the other roll, a spring, e, in the recess of the roll E and a spring, e', in the recess of the roll E, substantiallyv as and for the purpose set forth.
2. In a horseshoe-nail machine, the tube F, the feeding-ingerf, the forming-rolls C and C D an d D', the pointing-rolls Eand E', and the channel-pieces G and II, in combination with the shafts B B B and pinions I) b b, and suita ble driving mechanism, substantially as herein set forth.
3. In a horseshoenail machine, the combination, with the pairs of rolls D D and E E, of a channelpiece, H, placed between the said pairs of rolls to convey the nail from one pair to the other, and converging spring-fingers h h, secured within the channelspiece, substantially as and for the purpose set forthY 4.. In a horseshoe-nail machine, the combination of bearing-collars ou the ends of the shafts B B B with the shoes I I l, adjusted by the sety screws it' z', engaged in the flange-pieces a2 a2, substantially as and for the purpose described.
In witness whereof I hereunto subscribe my name this 22d day of June, 1886.
JOHN PETER VENNERSTEN.
