IMP'ROVED .NAIL-MACHINE.
Specification forming part of Lcttels Patent No. 92,994, dated July 27, lt).
To all whom it may concern, i
Beit known that I, GEORGE OsBoRN, of Lakeville, of the county of Plymouth and State of Massachusetts, have invented a new and use `ful or Improved Machine for Making Cut Nails;
the sector of a circle and alternately from one to the other-of such sets of cutters, so as to introduce the strip of nail-plate to each of them in succession. By this combination there is avoided the necessity of turning the nail-plate over and back, as is necessary when onlyasingle set of cutters-that is, astationarybed-die and a movable cutter or dieis employed. Vith my invention a tapering nail-blank is severed from the strip immediately after the termination of each lateral movement of the nail-plate carrier. Furthermore, in this machine there is employed with the two sets of cutters and the vibratory nail-plate carrier what is termed the intermediate guard,77 the purpose of it being to prevent the nail plate or strip during its passage from one set of cutters to the other from being accidentally forced into the space between the two movable cutters, so
as to be improperly carried into contact withy either cutter. This guard also directs the nailstrip properly toward that movable gageguard against which at any time it may be in progress. There are also in the machine what are hereintermec movable gage-guards,77 there being two of them. The purpose of each is to direct the strip to the gages by which each nail blank is sustained at its middle preparatoryto being caught by the gripping mechanism and headed by the header.y Y
In the drawings, A and B denote the two stationary or bed-cutters, arranged withinsockets in a standard, C, erected on the bed-plate D of the machine. Placed between the pairs of cutters, and fastened on `the upper surface of the standard C, is the intermediate guard, E, which is formed with a lip, c, extended up from its inner end. The breadth of the guard at the top is equal or about equal to the distance between the two movable cutters F G, which are fixed in movable goose-necks or arms b o, plvoted to the bed-plate of the machine and arranged in manner as represented. These cutter-arms are provided with springs d d for raising them at the proper times. Extending acrossthem, and having its journals sustained in bearings in the standards e e, is a cammed shaft, H, which carries two wipers or cams, jf, for operating or depressing the cutter-arms. To each set of cutters there may be mechanism for suitably holding or gripping the nail-blank and heading it after it may have been sepa-Y rated from the strip by such s et of cutters. Such mechanism is shown in part in the drawings; but as it is like that commonly used in nail-machines, no further description of it is necessary.
The vibratory nail-strip carrier is shown at l. It consists of a spout terminating in abow or arch, g, having a hole 'through its center for the passage of the nail-strip. Two springs or spring-jaws, h h, iixed to the bow g, are arranged therein and in the said hole in manner as represented. These springs embrace the nail-plate on its opposite edges and hold it with friction while the carrier may be at Work. The carrier is pivoted to the top of a post, K, so as to be movable laterally. The front end ofthe carrier while in motion traverses across the ded-dies and the intermediate guard. The said carrier is also connected with a right-angular lever, L, which derives its motion from apitman, M, that abuts against and extends through one arm of such lever, and is furnished with a spring, k, arranged in manner as represented. This pitman at its inner end is jointed to a pendulons lever, Z, .Whose fulcrum is shown at m. The upper arm of the said leverZ rests against the periphery of acam, u, such cam being carried by the cam-shaft hereinbefore men;v tioned. A spring, o, fixed to the lever and resting on a stud, p, arranged as represented, servesto move the lever in the direction opposite to that in which it may be movedbythe cam While the latter may bein revolution. By
means ofthe said cam, lever, spring, pitman and bent lever a reciprocating vibratory movement will be imparted to the strip-carrierwhile the cam-shaft may be in revolution, such movement causing the nail plate or strip to be presented in succession to each of the pairs of cutters which are to be arranged and operated, so that at each presentation a wedge or frustum or tapering blank may be separated from the strip by their cooperative action during the vdownward movement of the upper cutter of the pair. By depressing the spring o the pitman may be caused to move freely within the arm of the bent lever without producing any movement thereof. i
A nail-strip or piece of metal to be cut up into blanks for the formation of nails after having been run into and through the carrier will by such carrier, when the machine is in operation, be moved or vibrated from each pair of the cutters to the other, and provided the strip be suitably advanced in the meantime it will be gradually reduced to nail-blanksby the cut,- ters. At or near the terminus of each lateral movement the strip will bring up against one of two lateral stops, q q, arranged on the stationary cutter-supporter in manner as represented. Each of the springj aws hhin its turn co-operates with one ofthe lateral stops in holding the nail-plate, although while the latter may be a lateral movement it will be held by both the springs. After having passed bythe intermediate gage, the nail-plate will be forced against one of two movable gageguides, o r,
which are shown in Fig. et, such ligure being a top view of them, the said gage, and thelower cutters. These gage-guards are two bent levers, which are pivoted to opposite sides of a standard, s, one of them being shown in Fig. 2. Theil' upper arms extend up in rear of lthe camshaft, and are operated by camst t, projecting from such shaft. levers as to cause their lower arms to rise, they at the proper times being caused to fall downward by the action of gravity or by springs suitably applied to them. The gage-guards prevent the plate from being advanced out of time, and are for the purpose as hereinbefore stated.
Vhat I claim as my invention in the abovedescribed machinery for cutting nailsis as follows, viz: y
The arrangement and combination of the movable gageguards 'r r, (provided with meehanism for operating them, as deseribed,) with the intermediate guard, E, the two series of cutters A F B G, and the vibratory nail-plate earrier I, the whole being essentially as set forth.
