SPECIFICATION forming part of Letters Patent No. 628,886, dated July 11, 1899.

I Application filed June 18, 1898. $611M N (N0 model-l T0 (til whom it may concern.-

Be it known that 1, DAVID E. HUNTER, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Lock-Rods for Cards, of which the following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representinglike parts.

to This invention is an improved lock-rod or vention more particularly defined in the appended claims, reference being bad to the accompanying drawings, illustrative of one embodiment of the invention.

In the drawings, Figure 1 is a central longitudinal vertical section of a preferred embodiment of my invention shown in operative position in a card-drawer, parts being broken away. Fig. 2 isla top plan view showing the device removed from the drawer.

The drawer A may be of any usual or preferred kind adapted to receive cards, being herein shown as provided adjacent its front wall a with a usual inclined block b, against which the cards may be tipped in use when held in place by the rod 0, which enters the usual perforations in the cards, as will be readily understood.

The rod 0 may be of any kind desired suitable for the purpose, inasmuch as mypresent invention does not relate to the rod as such, but relates to the means for retaining and manipulating it. As herein shown, the rod is threaded at c and permanently secured in a plug or socket-piece D, preferably cylindrical in cross-section. Said plug or socket is adapted to be inserted in a housingd, which may be of any external shape preferred, and is mortised or otherwise retained in the box.

At its upper end the housing is perforated to receive a movable retaining device or dog d, herein shown as a plunger, and retained in a hollow projection or dome d brazed or otherwise secured to the housing, said plunger being normally held projected by a spring d bearing against its inner end and retained in the dome.

The plug D has a longitudinal slit or key- .apert'ure d to receive a key d said slit be ing herein shown as having a curved upper wall d to direct the key. The latter has at its forward end a hook-like prong 01 and the socket or plug D has an opening (i to'receive said prong or hook in alinement with. the plunger d when the 'parts are in position to be locked, it being understood that the plunger or device d at such times drops into said hole or openingd and locks the rod in the box.

In order that the plug or socket may be au tomatically locked by the device 01, I provide the plug with an inclined groove d (shown in side elevation in Fig. 1 and in top plan, Fig. 2,) up which the plunger may slide when the plug'is forced into the housing, the plunger dropping into the hole 61 when the plug has reached its innermost position.

The key,it will be observed,has an obliquelycut lower edge (1 The operation of my device is extremely simple and at the same time certain and exthen be in proper position opposite the opening (i and thereupon the operator simply forces the lower edge of the key forward, thereby swinging the projection d upwardly into the full-line position shown in Fig. 1 and forcing the plunger (1 out of the opening d so that the parts are thereby unlocked, leaving the key in the position shown with its hook or projection cl in place within the opening d rigid to act as a withdrawinghook. The operator then simply pulls on the key, and thereby withdraws the plug D and the attached lock-rod C. The key can then be reand scope of my invention.

moved or not, as preferred. When it is desired to lock the cards again, all that is necessary is simply to replace the parts, shoving the plug D forward, so that the plunger d is permitted to slide up the inclined way d and snap down into the hole d into locking position.

Itwill be understood that I am not restricted to the precise form and arrangement of parts shown and described, inasmuch as various changes in minor details may be resorted to without departing from the spirit It will also be understood that any desired kind of a lockrod may be used with my plug, the latter being intended merely to operate and lock the rod or rods, whether the latter are of the kind requiring to be drawn entirely out, as herein shown, or simply moved longitudinally or otherwise slightly in order to be released from the cards, and whether permanently or otherwise attached or connected o the plug.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'1. The herein-described device for-locking cards in position, comprising a rod held by a'plug at its outer end, a housing receiving said plug and provided with a plunger ordog, said plug having a slot or key-aperture, and an opening from said key-aperture registering with and adapted to receive said dog, and a key having a hook or projection corresponding t.o.said opening and'adapted to disdevice, said plug having an inclined groove said plug having a slot or key-aperture arched or downwardly curved at its upper forward end, and an opening from said key-aperture registering with and adapted to receive said dog, and a key having a hook or projection corresponding to said opening and adapted to dislodge said dog therefrom for unlocking the device, substantially as described.

4. The herein-described device for locking cards in position, comprising a rod held bya plug at its outer end, a housing receiving said plug and provided with a plunger or dog, a spring normally forcing said dog inwardly, said plug having a slot or key-aperture, and an opening from said aperture registering with and adapted to receive said dog, and a 7c key'having a hook or projection correspond-' ing to said opening and adapted to dislodge said dog therefrom for unlocking the device, substantially as described.

5, The herein-described device forlocking cardsin position, comprising means to engage and retain the cards, in combination with a locking and operating device therefor, said device comprising a plug, a movable dog arranged to engage and lock said plug, and a key in the form of a hook for unlocking said dog and simultaneously engaging said plug in position to operate the same for releasing the cards, substantially described.

In testimony. whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DAVID E. HUNTER.
