EDWARD MAYNZ, OF BOSTON, MASSACHUSETTS.
MACHINE FOR ATTACHING LACING-HOOKS.
SPECIFICATION forming part of Letters Patent No. 308,914, dated December 9, 1884.
Application filed January 16, 1881. (X model.)
To aZZ whom it may concern.-
Be it known that I, EDWARD MAYNZ, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Devices for Attaching Lacing'Hooks, of which the following is a full, clear, and exact description, reference being had to the ac companying drawings, forming a part of this specification, in explaining its nature, in which- Figure 1 is a side elevation of a setting-in- Y strument containing my invention. Fig. 2 is a view, part in side elevation and part in vertical section, illustrating the operation of my invention. Fig. 3 is still another View in elevation and vertical section of the same parts shown in Fig. 2, and still further illustrates its operation.
This invention is an improvement upon that described in my Patent No. 217,018, dated July 1, 1879, and it relates especially to the means employed for holding or supporting and clamping the lacinghook while its prongs or fastening are being driveninto and clinched in the material to which the hook is attached.
Referring to the drawings, A represents the head of the machine. It is mounted upon a suitable post, 13, and it has the table a, which carries or supports a disk, 0, which is adapted to be revolved thereon, and which has in its upper surface the circular die-recess 0. Above this die-recess is arranged a plunger, D, which has suitable hearings in the frame A, and is moved downward by means of the lever (1, rod cl, and treadle d, against the stress of the spring (1 which, upon the release of the treadle, moves the plunger, lever, rod, and treadle upward to their respective normal positions. 1
To prevent the rod from turning, I use the arm ti and steady-pin or guide (1 the arm being rigidly secured to the plunger-rod D,
and having a hole through which the steady pin passes. At the lower end of the plunger is attached by the screw 0, the plate 6, carrying the tongue E, which projects inwardly at right angle to the vertical portion 6 of the 1 plate, and is of a thickness about sufficient to fill the space between the seat f of the lacinghook and the head f. (See Fig. 1.) There is'also attached to the plunger D a springarm or curved spring, 9, which preferably is shaped, as shown in the figure, so that when the plunger is in its highest position there is a space left between its inner edge and the end of the spring-arm sufficient to permit the placing of the hook upon the tongue, as shown in Fig. 1. The end or bearing portion of the spring-arm should have a position opposite the inner edge of the tongue, and upon the downward movement of the plunger the outer surface, gf, of this arm, which is in reality a movable jaw, is forced by the shoulder 9* against the outer edge or surface of the neck of the lacing-hook, and clamps it securely to the tongue. This position is well shown in Fig. 2. And upon the further descent of the plunger D the end of the spring-arm g is still held in contact with the neck of the lacinghook, and clamps it upon the tongue, but as the plunger moves downward the spring moves from'the shoulder 9 which first throws it into contact with the neck of the tongue down the front side, of the bar 9, this front side in reality being a guide. This bar 9', which provides the shoulder g and the guide, is supported by the arm 9 which is preferably made to yield to a limited extent, and which is fastened to the frame A of the machine at g. The bar not only serves as a guide, but also as a gage against which the edge of the material H is moved before the hook is set, so that each hook can be set at a uniform distance from the edge of the mate rial.
Of course I do not confine myself to the use of a die-block such as is shown and described, for I may use a stationary die instead of a revolving one, if I prefer. Neither do I confine myself to the specific mechanism herein described for reciprocating the plunger.
It will be observed that the tongue, the
' spring y, and the guiding-block 9 in substance constitute an automatic clamping device or jaw, one member of which is fixed and the other is automatically moved and held in place to clamp the hook firmly upon the tongue.
Of course this device can be used for setting lacing-hooks having tubular fastenings, as well as lacing-hooks having pronged fastenings, as shown, the only change in the mechanism necessary for adapting it to this use being simply the providing of a suitable die for upsetting the under portion of the tubular fastening, and such dies are in com- D1011 use.
It will be observed that on account of the shape of the spring and of the shoulder g and grinding-surface that when. the plunger has reached its lowest position, the spring arm does not bear against the neck of the hook with as great stress as it did when it is first brought in contact with it, and this enables the material to he slipped with the hook laterally with the tongue. Upon the upward movement of' the plunger when the descend ing end of the spring-arm clears the shoulder 9 it moves automatically backward out of position.-
It will be observed that the portion can bear not only against the outer side of the neck portion of the hook, but that it can also bear upon the under side of the neck portion, so that the pressure against the tongue shall be upward or diagonally upward, instead of horizontal.
Having thus fully described my invention,
I claim and desire to secure by Letters Patent of the United States 1. In a machine for attaching lacing hooks,
the combination of the plunger D, having the tongue and the spring-j aw g, arranged to be moved automatically toward the end of the tongue during the downward movement of the plunger, whereby the neck of the lacinghook is clamped to the tongue. all'substair tially as and for the purposes described.
2. The combination of the plunger D, the tongue E, thejaw g, and the shoulder 9, all substantially as and for the purposes described.
3. The combination of the plunger D, the tongue E, the jaw g, the shoulder gf, and the guiding-surface g, all substantially as and for the purposes described.
4. The combination of the plunger D, the tongue E, the jaw g, and means for automatically moving it toward and from the tongue, as described, with the die 0, all substantially as and for the purposes described.
5. The combination of the plunger D, the tongue E, thejaw g, and means forautomatically moving it toward the tongue, as de scribed, and the die 0, with the gage c", all substantially as and for the purposes described.
EDYVARD MAYNZ.
