LEAD AND CEAYON HOLDER.

SPECIFICATION forming part of Letters Patent No. 340,925, dated April 27,1886.

Application filed March '23, 1856. Serial No. 196,2I7. (No model.)

To all whom it may concern:

Be it known that I, GUsrAE REINHOLD SAN- DELL, of the city, county, and State of New York, have invented certain new and useful Improvements in Lead and Crayon Holders, of which the following is a specification. The lead and crayon holder in which my invention is embodied is of the stop gage type, and is one in which the lead-grasping device is operated at or near the conclusion of its forward movement (or movement in the direction necessary to release the lead) to close sufficiently to intercept or check the lead at the time when the point ofthe latter projects a predetermined distance beyond the tip or front end ot' the holder. A stopgage holder possessing this characteristic is not new with me, broadly considered, one form of the same being disclosed in Letters Patent N o. 265,730, of October 10, 1882. In said patented device is also a lead-detent which retains the lead until `the lead-grasping device has advanced and closed in its stop-gage position, and which then opens and releases the lead and allows the latter to fall as far as permitted by the stop-gage.

rIhe holder in which my invention is conn prised contains both of these devices. The lead-grasping device consists of longitudinally-movable spring-controlled jaws which nor- Inally stand apart, like the jaws of the ordinary automatic pencil. rl`he lead detent or retain ing device consists of a split collapsible noz zle arranged within or between the jaws and fast to the sheath or case of the holder, so that the jaws can move longitudinally withreference to it. In the jaws, at proper points in rear of their grasping ends, are formed slots into which fingers or pressers extend, said tingers or pressers being fast to some part (such as the sheath or the nozzle) with reference to which the jaws are longitudinally movable, and the arrangement being such that normal ly, or when the jaws are retracted, said fingers or pressers shall occupy such a position as to exert no appreciable closing-pressure upon the jaws, but that when the jaws are protruded the fingers or pressers shall bear externally from opposite sides upon the jaws or the jawstems,and thus cause the jaws to close in their stop-gage position. The pressers or fingers sition. l protruded and grasped by the jaws.

are used also to cause or permit the proper action ot' the lead detent or collapsible nozzle, it being` requisite that the detent or collapsible nozzle should remain closed while thejaws are moving forward to stopvgage position, and should then open to allow the lead to drop.

The nature of my improvement and the manner in which the salue is or may be carried into effect will be readily understood by reference to the accompanying drawings, in which- Figure l is a vertical central section, partly in elevation, of aholder embodying my invention in its preferred form, the lead being represented in retracted position. Fig. 2 is a similar section with the parts in the position which they assume when the jaws are halfway protruded. Fig. 3 is a like section with thejaws fully protruded and in stop-gage po- Fig. 4 is a like section with the lead Fig. 5 is a perspective view of the front ends of the jaws and the collapsible nozzle. Figs. 6 and 7 are longitudinal sectional views of a modification, which will be hereinafter more particular] y referred to.

A is the sheath or handle, terminating in the usual tip or nozzle, a.

B is the tube, corresponding to the lead-receiving tube of the ordinary automatic77 pencil. and, like that tube, terminating at its front end in spring-controlled grasping-jaws b,which -normally stand apart and are caused,when the nozzle, c, which is arranged within the jaw-,

tube B, and by a pin, passing through a slot, y, in the jaw-tube, is so connected with the sheath or handle as to be incapable of following the longitudinal movement of the j aws.

In each jaw,a proper distance in rear of its Ioo acting end,is a longitudinal slot, d, at the rear end of which is the shoulder d,which is to be pressed at the time the jaws are fully proindicated in Fig. 2.

truded, in order to close them in stop-gage position. The fingers or pressers to act on these shoulders are seen at e. Two different arrangements of them are shown. In Figs. l to 5,inclusive, they are represented as consisting of rearwardly-extending prongs on the collapsible nozzle, which project up through the slots d. At the points where these prongs join the collapsible nozzle they are somewhat inclined on that face which adjoins the shoulder d', as seen at e', and said part e is so located with reference to the part d that when the jaws have reached their protruded position the faces e' will have pressed upon the shoul ders dsufliciently to force together or close the jaws. Indeed,in this arrangement the action of thejaws and the nozzle is reciprocal, for the same instrumentalities which causethe jaws to close will also cause the split or collapsible nozzle (which in Figs. l to 5 normally closes) to open.

The mode of operation ofthe holder in Figs. l to 5 is as follows: The parts are shown in Fig. l in the position they occupy when the lead is retracted. To protrude the lead, the pencil is held point downward and the pressure-cap is pushed forward,thus advancing the jaws, which open or release the lead while the collapsible nozzleI clasps the lead, with suflicient firmness to hold it from dropping, allas This condition of affairs continues until the jaws are fully protruded, at which time,by the action of the parts d e', the jaws will have been closed to stopga ge position, the collapsible detent or nozzle will have opened enough to release the lead, and the lead will have dropped as far as permitted by the jaws, as indicated in Fig. 3. The pressure-cap being released, the jaws at once return to position, the lead being held during their return by the collapsible nozzle, and the jaws opening so as to pass the lead without drawing it back until they bring up against the tip a,and are thereby closed upon the lead tightly.

In the arrangement shown in Figs. 6 and 7 the fingers or pressers e, instead of being carried by the collapsible nozzle,are attached directly to the interior of the case or sheath, and they have a slight spring action. Their acting ends e normally stand in the slots (Z, and bear from opposite sides upon the split nozzle c. The light spring-jaws of the nozzle in this arrangement are not normally springclosing, as in the one just above described,but, on the contrary,are set so as to normally stand apart far enough not to press upon the lead. So long as the pressers e are in the slots d they bear upon and close the split nozzle, as seen in Fig. 6. When, however, the jaws are fully protruded, as seen in Fig. 7,the pressure of the parts e is transferred from the split nozzle c to the shoulders d of the jaws, thus closing the latter into stop-gage position, and permitting the former to open and allow the lead to drop. i

I am aware that it is not new to use in a lead and crayon holder two sets of grasping devices which act upon one another in such manner that the opening of the one set causes the other set to close, and this I do not broadly claim.

Having now described my improvement and the best way known to me of carrying the same into effect, I desire to be understood, in conclusion,that I do not restrict myself to the details of construction and arrangement hereinbefore set forth, for the same obviously can be varied considerably without essential departure from the principle of my invention; but

What I claim herein as new is-.

1. The combination of the sheath or handle, the collapsible or split nozzle, the longitudinally-movablespringcontrolled and normallyopen lead-grasping jaws, provided each with a longitudinalgstop gage slot and shoulder, and the arms or pressers arranged and adapted to bear externally upon thejaws and to operate in connection with said slots and shoulders, substantially in the manner and for the purposes hereinbefore set forth. Y

. 2. The combination of the sheath or handle, the collapsible or split nozzle, the longitudinally-movable lead-grasping jaws provided each with a longitudinal stop-gage slot and shoulder, and rearwardly-extending arms or prongs fast to the split nozzle, projecting into and through said slots and arranged and adapted to operate in connection with said shoulders, as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 19th day of March, 1886.

GUSTAF REINHOLD SANDELL.
