APPARATUS FOR COVERING LAClNG-HOOKS.
SPECIFICATION forming part of Letters Patent No. 569,969, dated October 20, 1896.
I Application filed January 30, 1896. Serial No. 577,405. (No model.)
To a whom it may concern.-
Be it known that I, ELEAZER KEMPSHALL, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Covering Lacing-Hooks, of which the following is a specification.
This invention relates to means used for applying a covering of plastic material,such as pyroxylin composition, to metallic articles, such as the heads of lacing-hooks; and it has for its object to provide a simple and convenient apparatus of this class whereby the covering operation may be rapidly and efficiently performed.
The invention consists in the improvements which I will now proceed to describe and claim.
Of the accompanying drawings, forming a part of this specification, Figure 1 .represents a top plan view of a portion of the supporting plate or base forming apart of my improved apparatus. Figs. 2, 3, and at represent sectional views on the line 2 2 of Fig. 1, on an enlarged scale, showing the parts of the apparatus at dilferent stages of the operation. Fig. 4: represents a perspective view of the holder for the article to be covered. Figs. 5, 6, and 7 are top views, each showing a portion of the base-plate and a lacing- Fig. 8 represents a view similar to Fig. 4, showing a surface formed to mold the covering on the neck of a lacing-hook. Figs. 9 and 10 represent sectional views showing a diiferent mechanical construction embodying my invention.
The same letters of reference indicate the same parts in all the figures.
'In'the drawings, referring first to Figs. 1 to -8, inclusive, a represents a base-plate, in which is formed a socket a, which is of substantially cylindrical form. In this socket is fitted-to move in and out a holder 1), which is adapted to hold an article to be covered,
the said article being in this case a lacinghook c. The holder b has an outer face I),
which, when the holder is at the bottom of the socket, is within the outer end of the socket, as shown inFigs. 3 and 4, the socket extending above or outsideof the face band plate a, said die having a cutting edge e and being formed to press the blank cl down upon the head of the lacing-hook held by the holder 1), cutting off the surplus marginal portion of said blank and forcing a portion of its material through an orifice or orifices in the head of thelacing-hook and against the face 1) below said head, thus forming a molded cover 0, which is interlocked with or anchored to the head of the lacing-hook, as shown in Fig. 4, the face I) constituting a bottom die which cooperates with the top die 6.
- The holder 19 is movable in the socket Ct to elevate the face I) and the lacing-hook thereon above the base-plate a, as shown in Fig. 2, for the ready removal of the covered hook and the application to the holder of an uncovered hook. The holder 1), as here shown, has a cavity 11 below the top face I), said cavity being formed to receive the shank portion of the lacing-hook. In one edge of the top face 6 is formed a recess b communicating with the cavity 19 and formed to receive the neck which connects the head and shank of the lacinghook.
I prefer to form an enlargement a at the upper end of the socket a, said enlargement being above the top face b of the holder 1) when the latter is in its lowest position in the socket, the bottom a of said enlargement being flush with and constituting auextension of the topface b of the holder, said extension being arranged to cooperate with a portion of the cutting edge e of the die e in forming the margin of the cover 0 at and near the neck of the lacing-hook.
The holder 6 maybe guided in its movements and prevented from rotating in the socket by anysu'itable fmeans, preferably a key or spline 'g, inse pain a cavity formed for I l its receptionin the-wall of the socket a and projecting into a groove gfi formed in the holder b, the inner end of said groove and the lower end of the key g forming stops which limit the outward movement of the holder, as shown in Fig. 2.
The operation is as follows: The holder 7) being raised, the lacing-hook is placed upon it, as shown in Fig. 2. The holder is then depressed, carrying the hook into the socket, and a blank d of pyroxylin composition is placed in the mouth of the socket above the holder and resting on the head of the hook, as shown in Fig. 3. The die e is then depressed, as shown in Fig. 4, and molds the material of the blank in the manner described and shown, the holder, base-plate, and die being suitably heated to soften the blank and makeit sufficiently plastic to assume the form shown in Fig. 4. After the formation of the cover, the holder 1) is raised, thus removing the covered hook from the socket and permitting its ready removal from the holder.
The base-plate a in practice will contain a large number of sockets and holders, and said plate is preferably portable or movable, so that it may be set up edgewise while the uncovered hooks are being applied, and may then be placed horizontally upon a suitable supporting-bed while the dies 6, which are assembled in a corresponding number on a suitable die plate or holder e, are being brought down to mold the covers.
The holder 1) may be simultaneously raised to eject the covered hooks from the die-plate by placing the die-plate upon a series of pins or spindles i, affixed to a suitable supporting base or plate and arranged to coincide with orifices 1., formed in the bottom of the baseplate a and communicating with the sockets a, the base-plate a being removed from the bed which supports it during the molding operation above described and placed upon the pins 11, which support the holders in their elevated position during the removal and application of the hooks. Any other suitable means may be used for simultaneously raising or displacing the holders without departin g from the spirit of my invention.
I do not limit myself to the provision of blank-receiving cavities in the socketsat the outer ends of the holders, as the blanks may be cut by the dies from sheets placed between the dies and bed, or the blanks, if previously formed, may be held in any other suitable way.
It is obvious that the essential features of my invention, namely, a base-plate havinga socket and a holder formed to be contained in the socket and to hold the article to be coated therein, the holder and socketed plate being relatively movable, so that the holder and a portion of the article engaged therewith are securely held within the socket when the said parts are in their operative position and are removable from the socket to permit the ready application and removal of the article, may be used in apparatus for covering other articles besides l'acing-hooks, the form of the holder and die and, if necessary, of the socket in the base-plate being modified to suit the form-of the article.
By my improvement I am enabled to form a cover upon a lacing-hook or other like article without forming a mark across the top surface of the cover, as is necessarily the case when said top surface is formed by two halfdies the joint of which extends across said surface.
In Fig. 8 I show a cavity a formed in the wall of the socket a adjacent to the recess b in the holder 1), said cavity being formed to mold an extension of the cover on the outer side of the neck of the lacing-hook.
In Figs. 9 and 10 I show the holder as a stud or projection 12 formed on a fixed bed or plate Z2 the corresponding socket a being formed in a removable plate 0. In this case the holder is exposed for the application and removal of the article by removing the plate 0. the holder being covered and the article confined by placing the plate (0 on the plate Z2 I claim- 1. An apparatus of the character specified, comprising a base or plate having a socket which is open at the upper side of the plate, a holder formed to be inclosed by said socket and having a cover-molding upper face or bottom die adapted to support a head to be covered and a shank-receiving cavity below said face, and a top die formed to act on a plastic blank interposed between the holder and die, the holder and socketed plate being relatively movable to cover and uncover the holder.
2. An apparatus of the character specified, comprising a base or plate having a socket, a holder movable in said socket and adapted to support an article to be covered, a die formed to act on a plastic blank interposed between the holder and die, and means for displacing the holder to raise the covered article from the socket.
3.
