BENHARD YOCII, OF BELLEVILLE, ILLINOIS.

MACHINE FOR POINTING CUT NAILS.

SPECIFICATION forming part of Letters Patent No. 465,960, dated December 29, 1891. Application filed February l2, i890. Serial No. 340,131. (No model.)

.To @ZZ whom it may concern:

Be it known that I, BENHARD Yoon, of Belleville, in the county of St. Clair and State of Illinois, have invented a certain new and useful'Improvement in Machines for Point-ing Cut Nails, of which the following is a full,v

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in machines for pointing cut nails; and it consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a vertical longitudinal section of my machine, taken on the line I I, Fig. V. Figs. II to IV, inclusive, are views of the pointing-dies, Fig. II being asection and Figs. III and IV perspective views, Fig. III shoW- ing the dies open and Fig. IV showing them closed. Fig. V is a top or plan vieur with the lcutters and their holder removed. Fig. VI

is a perspective View of the nail-discharger. Fig. VII is a section of same, taken on line VII VII, Fig. IX. Fig. VIII is a detail perspective view of same. Fig. IX is an end View of the holding and pointing dies and the nail eXpeller or discharger. Fig. X is an end view of same, showing a modification of the discharger. Fig. XI is a section taken on line XI XI, Fig. X. Figs. XII and XIII are detail views illustrating the operation of the nail-discharger. Fig. XIV is a vertical transverse section taken on line XIV XIV, Fig. V. Fig. XV is a detail perspective view of the fixed pointing-die and its holder. Fig. XVI is a detail vieW of the nail before it is pointed. Fig. XVII is a similar View of the nail after it is pointed, but before the iin is removed; and Fig. XVIII is a similar view of the nail after it is pointed and the iin is removed; Fig. XIX is a plan View of one of the pointing-dies; and Fig. XX is a similar View, showing a die not provided with myimproved cuting-edge for splitting the fin beyond the point 0f the nail.

Referring to the drawings, l represents the main frame of the machine. 2 represents the movable knife; 3, the fixed knife; 4, the head carrying the movable knife; 5, the lever for moving the knife; 6, the shaft, provided with a cam '7, for moving the knife-lever; 8, the fixed, and 9 the movable holder for retaining the nail while it is being headed and pointed, and l0 the heading-die. All of these parts are old, so far as my present invention relates, andas they are not a necessary part of the operation of the parts to which my present invention relates, a further description of them is thought to be unnecessaryin this application. A description of these parts will be found in my applications now pending filed April 6, 1889, and September 4, 1889, serially 1 numbered, respectively, 306,245 and 322,936.

The movable pointing-die 19 in my present application is supported on the upper end of an arm 20, the head 20 of the arm being recessed, as shown in Fig. XV, to receive the die, which is held to the arm by means of a plate 2l. The inner end of the die fits against a shoulder 22 at the inner end of the recess that receives the die, and thus any backward movement of the die while pointing the nail is prevented, and the plate 2l holds the die from vertical movement, while at the same time it can be quickly taken out to be sharpened and can be easily and quickly replaced. The arm 20 is supported on a shaft or rod 23, fitting in sockets 24 in the frame of the machine. The rod 23 is susceptible of end movement in its bearings, so that the die can thus be adjusted laterally when desired, and, as is often-necessary, when a die has been sharpened or when a new'die is applied. This adjustment I prefer to effect through means of set-screws 25, which pass through the frame of the machine and are provided with jamnuts 26, to prevent them from turning accidentally. It Will be seen that by loosening on one of the set-screws and tightenin0r on the other the rod 23, and consequently the diearm 20, may be shifted laterally in either direction, as may be found necessary. The arm 2O is secured to the shaft or rod 23 by means of a bolt 27, which passes through an elongated opening 28 in the shaft or rod, (the shaft or rod at this point being flattened out, as shown in Fig. I.)

29 represents a set-screw passing through the rod or shaft 23 beneath the bolt 27, and which is provided with a jam-nut 30 and a IOO conical point 3l, fitting in a perforation 32 in the arm 20. It is often found necessary to adjust the movable die vertically as well as laterally, and I have provided a means of doing this by the use of the parts just described. It will be seen that by loosening ou the bolt 27 and tightening on the set-screw 29 the conical point of the latter will cause the arm 20 to be moved upward, the elongated opening 2S permitting the bolt 27 to be carried upward with the arm. In a like manner, if the die needs tobe moved in a downwardly direction, it can be done by loosening on the bolt 27 and turning the conicallypointed screw 29 in an outward direction. I am thus enabled to get both a vertical and a lateral adjustment to the movable die and to'get a very fine or accurate adjustment in either direction.

It is of course necessary that the mechanism for operating the movable die be such that it will not interfere with the vertical or lateral adjustment just mentioned, and for this purpose I use a link 38, which is pivoted at 34 to the head of the arm 20, and which has a conical recess 35 in its otherend, which receives the conical point of a set-screw 3G in a lever 37, which imparts the movement to the die. This connection between the arm 2O and the lever 37 permits of the adj ustment-s of the die to which I have referred. The lever 37 is provided with a friction-roller 39 on its free end, which is engaged by a cam 40 on the shaft (i to force the die forward. The die with the other parts is returned by a spring 4l, connected to the bed-plate of the machine at its lower end, and to a rod 42, projecting from the shaft 23 at its upper end.

The nails are liable to stick in the fixed die after being pointed, and for this reason it is necessary or desirable to provide a discharging device, which will relieve them from the fixed die as soon as the dies open. To accomplish this I place aback piece 44 between the fixed holder S and the fixed die 45. The

parts are shown in their position in Fig. V,

and the construction of the discharger is shown in Figs. VI, VII, VIII, and IX. The inner end of the back piece is formed with a recess, producing a shoulder 46, and the plate is grooved, as shown at 47, to receive a plunger 48, behind which is located a spring 49. The spring holds the plunger 48 normally in its outer position, or in the position shown in Fig. VII, and also shown in Fig. XII. As the nail is forced by the movable die and holder up against the fixed die and holder, the plunger 4S is by it forced from the position shown in Fig. XII to the position shown in Fig. XIII, the nail being brought back against the end 50 of the back piece 44, beneath the shoulder 46. Then as the movable holder and die recede the spring 49 will force the plunger 4S to its outer position and relieve the nail, so that it will drop from the machine.

For the purpose of adjusting the back piece 44, as may be found necessary, I slot its outer end, as shown in Fig. VII, and provide its set-screw 5l with a reduced portion 52, that fits in the slot 53 of the back piece. These parts will be seen by referring to Figs. VI, VII, and VIII. The setscrew 5l passes through the holder that retains the fixed die, the. fixed holder, and the back piece 44, and it will be seen that by turning inwardly or outwardly on this set-screw the back piece 44 will be adjusted in and out, as desired.

As a modification of the dischargcr I have shown two plungers, Figs. X and XI, each plunger having a groove inthe back piece 44.

In my applications referred to Ihave shown differentkinds or shapes to the faces of the dies for the purpose of producing different shapes of points on the nails. In this application I have shown the cuttingedges arranged in the form of the letter V, (see Fig. XX,) which would produce a point with afin, as shown in Fig. XVII. It is necessary where this fin adheres to the nail after the die is opened, as it often does, that it be removed, and in one or both of my other applications I have described a device for removing the fin. To assist in the easy removal of the [in I have in this application shown the face of the dies provided with a cutting-edge GO, which splits the fin beyond the point of the nail, as shown by the dotted line in Fig. XVII. This cutting-edge GO forms a die in the shape of the letter Y, as shown in Figs. III and XIX. By thus splitting the fm beyond the point of the nail it is much easier to remove it from the nail, as stated, and does not add to the cost of the production of the nails..

I claim as my inventionl. In a machine for pointing cut nails, the combination of a movable die and means for adjusting the die vertically, consisting of a rod to which the die-supporting arm is secured by a bolt fitting in an elongated hole and a conically-pointed screw passing through the rod and fitting in a perforation in the diesupporting arm, substantially as set forth.
