COMBINATION-INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 378,261, dated February 21, 1888.

Application led November B0, 1887. Serial No. 256,581. (No model.)

To ail whom t may concern:

Be it known that l, FRANK Molnrrnn, a resident ot' New York city, in the State of New York, have invented certain new and useful Improvements in Combination-Instruments,

or" which the following is a specification.

My present invention has relation to that general type of combination-instruments illusti'ated in Letters Patent No. 273,232, of Febio ruary 27, 1883-viz., an instrument in which is comprised a divided sheath or handle having its parts longitudinally movable with respect to each other,and distinctgrasping mechanisnis-one for eac-h part of the handle-coni 5 nected together, and each adapted to engage the device or article to be contained in its part of the handle, in combination with retreatingspring mechanism which normally holds the parts of the sheath in a position in which the grasping mechanisms will engage the device to be held by them.

The nature of my improvementand the manner in which the saine is or may be carried into ett'ect can best be explained by reference to the accompanying drawings, in which- Figure 1 is a longitudinal central section, partly in elevation, of theinstrnnientwith the penholder protruding from its end of the sheath. Fig. 2 is a like sectional elevation representing the lead projecting from its end of the sheath while the pen-holder is drawn back. Fig. 3 is a perspective view of the instrument with both lead and pen holder retracted.

It will be understood that the devices or articles to he held or contained in the sheath may be of any desired kind. For the purposes of illustration l have in the present instance provided a pencil or pencil-lead and a penholder, each to project from its own end of the sheath. The grasping mechanism for the lead is substantially that of the automatic pencil, so called, such as set forth in Reissued Let;

ters Patent No. 8,967,0f November 18, 1879. The graspii'ig mechanism for the pen-holder is substantially that of what is now known in the market as the Arrow7 pen-holder, such as set forth in Letters Patent No. 356,996, of February l, 1887.

A is the sheath or handle.

B is the pen-holder, sliding freely within the handle, and having a tubular stock or shank which fits within the said handle, so as to give steadiness to the pen-holder.

Gis the springclosed cover or stopper for the pen-holder end of the sheath, hinged or loosel y j ointed toits pusher-rodG, and adapted, when the pen-holder is protruded, to engage a notch, c, in the latter, as seen in Fig. 1, all substantially as described in Letters Patent No. 356,996, above named. The pusher-rod G, however-unlike the correspondinglynamed rod in said Letters Patent last referred to-is tubular, and is closed at its end adjoining the cover O, so as to form a lead-receiving tube similar to the longitudinallymovable lead-receiver of the automatic pencildescribed in Reissue Patent No. 8,967, hereinbefore referred to. The end of this tube G from which the lead is intended to 7; project terminates in spring-expanding clamping-jaws c, similar to the clampingjaws of an automatic pencil; and these jaws are, by a retreating-spring, (hereinafter described,) normally closed by being drawn against the contracted portion b of the tip T. The tip beyond its contracted portion is expanded into a globular or other suitably-shaped nozzle, T, (perforated for the passage of the lead,) which completely covers and shields the lead-grasp- 8o ing jaws, there being sufficient room within the part T for the longitudinal movement of the jaws necessary to permit them to move far enough away from the contracted portion or .neck b to allow of their expansion and the consequent release of the lead. rlhis featureviz., the covering of the jaws by the nozzle T-is a feature which may be applied to the ordinary automatic pencil, as well as to the combination-instrument represented in the 9o drawings, although in the instance last named it has the added advantage of furnishing a convenient knob or pressure button or cap for operating the cover C, as will be hereinafter explained.

I may state here that I am aware that it is not new to provide a covering sleeve or nozzle which completely conceals and covers the jaws, such a device being shown in Letters Patent No. 223,498, of January 18, 1880; but roo in said patented device the covering sleeve or nozzle is distinct and separate from the tip cap for operating the cover or stopper C.

the covering-nozzle is merely a prolongation of the compressing-tip.

The tip, which in effect forms part of the sheath or case A, is made longitudinally movable with reference to said part A, for the purpose of forming a spring-retracted pressure- To this end it ts and is adapted'to slide back and forth in a sleeve, D, fixed in the pencil endofthe handle A, said sleeve being provided as a convenient receptacle for the coiled spring E, which is confined between a shoulder, d, in the tip and a washer, d', which brings up against an inturned annular flange, e, on the inner end of the sleeve D. This washer d ts loosely around the tubular rod G, and a projection, f, on said rod G is so placed that when the rod is pushed in a direction to advance the lead-grasping jaws said projection j' will bear against and push forward the washer d', thus compressing the spring E. When pressure on the rod G is removed, the spring by its expansion will retract the jaws and draw them again into contact with the contracted neck b of the tip. Now, under this arrangement it will be seen that by pressing inward the tip T against the stress of the spring E the head or nozzle T', by bearing against the jaws, will press forward the rod G, and will thus operate the stopper or cover C and cause it to'open. As soon as this pressure is removed from the tip the retracting-spring E at once returns the parts to their normal position.

It remains to describe the manner of operating the jaws in order to cause them to expand, and thus release the lead, which operation is brought about by a longitudinal movement of the tubular rod G in a direction opposite to that in which it moves in opening the stopper C. For this purpose the rod G is jointed not directly to the cover or stopper C,

but to a rod, g, which passes through the stopper, and is provided with a presser-cap, h, between the head of which and the opposite end of the interior of the hollow stopper is conned a spiral spring, z', said spring tending to hold the rod g normally retracted outwardly. By pushing the pressure-cap z' inwardly it will be caused to push the tubular lead-holding `rod G in the direction necessary to permit the hereinbefore described, and represented in the accompanying drawings in illustration of my invention; but

What I claim herein as new and of my own invention is as follows:

l. The combination, with the sheath, the longitudinally-movable lead-containing tube or rod, and the lead-grasping mechanism located at one end of the sheath, ofthe cover or stopper placed at and adapted to close the opposite end of the sheath and hinged or loosely jointed to said longitudinally-movable leadcontaining tube, and the retracting-spring operating to move the said tube in the direction necessary to cause the stopper to close its end of the sheath.

2. The combination, with the sheath, the longitudinally-movable lead-containing tube and clamping-jaws, the longitudinally-movable compressing-tip for said jaWs,and the retracting-spring, of the freely -sliding penholder or other article adapted to project from the end of the sheath opposite to that fromy which the lead projects, and the cover or stopper hinged or loosely jointed to said lead-containing tube, the combination being and acting substantially as set forth.

3. The combination, in an automatic pencil-holder, with the sheath, the lead-containing tube, and thelead-grasping jaws, of ajawcompressing tip provided with a nozzle, T, which covers and conceals said jaws and is perforated for the passage of the lead, substantially as and for the purposes hereinbefore set forth.

4. The combination, with the sheath or case and the cover or stopper, of the longitudinally-movable lead-containing tube forming a pusher-rod for said vcover or stopper, and the presser-rod mounted and longitudinally movable in said stopper and hinged or loosely jointed to said lead-containing tube, as and for the purposes hereinbefore set forth.

5. The combination of the longitudinallymovable lead-containing tube, the sheath, the cover or stopper C, the presser rod and cap mounted and longitudinally movable in said stopper and hinged or loosely jointed to said tube, and the spring t', as and for the purposes hereinbefore set forth.

6. The combination of the sheath, the longitudinally-movable lead-containing tube terminating at its outer end in clamping-jaws, the longitudinally-movable jaw-compressing tip or nozzle, the retracting spring E,-the cover or stopper C, the freely-sliding tubular holder fora pen or other article, the longitudinally-movable presser-rod mounted in and carried by the stopper and hinged or loosely jointed to the lead-containing tube, and the spring z', these parts being arranged together for joint operation substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 28th day of November, 1887.
