MACHINE FQR HEADlNG TACK- STRIPS.
SPECIFICATION forming part of Letters Patent No. 385,747, dated July 10, 1888.
Application filcllseptcmher 1, 1885. Serial No. 175,927. (No model.)
To aZZ whom, it may concern.-
. Be it known that I, Josnrrr E. CRISP, of Somervillc, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Machines for Heading Tack Strips, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 represents in vertical section a machine containing the features of my invention. Fig. 2 is a plan view thereof below the line a: of Fig. 1. Fig. 3 is a vertical central section at right angles to that shown at Fig. 1. Fig. 4 is a View in perspective representing certain details of construction, which are here inafter more fully described. Fig. 5 is a View of the tack-strip, showing in perspective the successive operations of the machine thereon. Figs. 6 and 7 show views which further illustrate the operation of the machine. Fig. 8 is a perspective view of the head-forming tool. Fig. 9 is a perspective view of the tack-stripholding clamp. Fig. 10 is a view in plan of the presscr reversed. Fig. 11 is a view of a part of one jaw or clamp.
The primary object of the invention is to furnish mechanism for heading tack-strips. The tack-strip as it is submitted to the machine may have a head-connecting section of uniform width and height, as shown in the section in Fig. 5, to the right of the serrations; or it may have well-defined head-forming sections, as represented by the serrated or notched part of the strip. When this first form of strip is used, the first operation of the machine is to form therein by a \l or similar shaped former the pointed head'forming sections a. These head-forming sections of course will be somewhat thicker than the head-forming portions of the straight strip before it is submitted to this operation. They are then split lengthwise and in succession by means of suitable one cross-head or hammer and reciprocated simultaneously, so that the operations of forming the head-forming sections, dividing or splitting the same, and forming the head are going on at the same time but on successive sections of the strip.
Referring to the drawings, A represents the frame of the machine.
B is a block provided with a reciprocating movement by means of the crank or eccentric b on the main shaft 1). This block is guided in suitable ways in the upright portion B of the frame of the machine, and it supports the various tools which I have heretofore referred to-nan1ely, the head-forming tool b the headsection'splitting tool 22", and the header b. These tools are all supported by the end of their respective screw-stems b and these screw-stems extend upward through the lower portions of the block into the space b. The lower portions of the tools pass through the pressure-block G, which is attached to the block B by the hooks c and pins 0, the hooks being attached to the block to hook upon the and the block B, in order that the presserblock may be kept forced out from the block B, excepting when it comes in contact with the head-forming portion of the tack-strip, when it yields to allow the tools to come in contact therewith. The springs extend into the holes I) in the block B, and upon the downward movement of the block are compressed to such an extent that its under surface comes in contact with the upper surface of the pressureblock. There is also a guide or steady pin, 0, attached to the head, which'projects into a hole in the presscr-block O.
The tack-strip is fed through the feedway D by means of the reciprocating feedpawls (Z d. These pawls are pivoted to their respective blocks d, so that they project into the feed way and engage the shanks of the strip, and they have a laterally-yielding movement in relation to the feedway in opposition to the springs d. The pawls are round or inclined upon the portions opposed to the feed, in order that they may ride over the shanks on their backward throw. The blocks d are reciprocated by means of the red at, to which they are fastened, the lever d, pivoted at d, and the push-pin d operated by the cam d and the spring (1. In addition to these feed-pawls there is the locking-pawl d, which is similar to them in shape, but does not reciprocate, its office being to engage the shanks of the strip and hold it stationary while the feed-pawls are moved back to take a new hold.
The tack-strip is supported during the operation of the tools bymeans of the two jaws E E. Thejaw E is moved by the arm 6 of the rock-lever e,'and the jaw E is moved by the bell-crank 6 which is pivoted at e", and the lever c has a projection, e", which extends into a groove or hole in the bellerank. lever 6 The lever e is reciprocated by means of the cam e on the main shaft and the connecting rod 6 and its reciprocating movement causes the jaws E E to be simultaneously moved to and from each other. The jaws are supported upon the bed-plate E in which is a portion of the fcedway.
The jaws E E each have a series of projections, 0, which are shaped to close under the head connecting portions of the tack-strip alternately, one from one side of the strip and the other from the other side. The upper surface ofthese projectionsisinclined toward their outer end, in order that they may shut under the head-connecting part of the strip and elevate it as they close sufficiently to lift the point of the shanks from contact with the under surface of the feedway. The front surfaces, 0, of the jaws shut against the sides of the shanks of the tack-strip, and the tackstrip is thus supported and clamped firmly by its shank, with thehead forming and connecting portions exposed to the action of the heading device.
The tack-strip is held stationary by the feed way upon the opening of the jaws. The extent of the throw of the jaws may be varied by means of the adj listing-screws, so that tackstrips of varying thickness may be headed without changing the jaws. The tackstrip, having been inserted in the feedway, is advanced by the feeding devices to the gang of tools. The first tool displaces the metal to provide the head-forming sections of the strip, the next tool in order splits the head-forming sections, and the next tool or header heads the sections already split. WVhile the tools thus perform separate functions they are operated simultaneously, and the feed is so regulated that upon the upward movement of the press the tack-strip is fed forward one tack. The presser-block 0, being a little in advance of the ends of the tools, comes in contact with the upper edge of the tack strip and holds it firmly in position upon the jaw while the tools are operating. This presser-block has a groove, 0 ofthe width of the head connecting portion of the tack-stri p from the hole of the headingtool I) to its right end and is flat upon its under surface, 0', beyond or to the left of the heading-tool. This portion of the presserblock acts in connection with the jaws to straighten or hold straight the strip whileitis being headed, and the strip thus held during the heading operation is prevented from spreading.
The head-forming section of each tack is redueed to shape in the lower part of the hole in the presser in which the headingtool reciprocates, which in connecting with the upper surface of the jaws makes a cup shaped die, and of course provides the head with a regular shape.
The indenting or displacing tool I) preferably has a central groove in its working-face and wings inclined outwardly therefrom, as shown in Fig.8.
When a tack-strip having head-forming sections well defined is used, it is of course nu. necessary to use either the tools I) or I)", and I would state that I may not use the tool I) even when the tool b? is employed.
Any mechanical equivalent maybe used for the parts described.
The groove in the under surface of the presser-block should close upon the head-connecting portion of the tackstrip before the clamps are closed sufficiently to tightly clamp the shanks, and the jaws remain closed until the presser-bar is lifted sufficiently to clear or become disengaged from thehead of the tackstrip.
It will be observed that the machine not only acts to head the tack-strip, but that it also delivers the same from the machine perfectly straight, and the heads and shanks separated by a uniform distance; and these ad vantages are of considerable value-the first because it enables the strip to be well packed for transportation; the second because it secures a more regular and perfect feeding and delivery of tacks in the tack-driving device.
Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a machine for heading tack-strips, the combination of a clamp or holding-jaws with the reciprocating tools I) b b, or either of them, all substantially as and for the purposes described.
