[51] lnt.Cl............... [50] Field of 1 MARKER-COUNTER navrcs BACKGROUND THE INVENTION :While the broad concept of marking and counting the marks is not new, there has not been provided in the past a satisfactory device in -the nature of a lead pencil or other similar hand-held writing implement, which conveniently marks items to be counted and simultaneously efiects counting of the items. While there have, in the past, been proposed complex mechanisms for achieving a marking and counting function, in a wide variety of situations these complex mechanisms were found to bulky, awkward, expensive and inconvenient to use. Hence, persons engaged in estimating, inventory taking, and other operations involving marking and counting, ordinarily utilized a pencil or other marking device and a separate counter or countingdevice.

SUMMARY OF THIS INVENTION Accordingly, it is an important object of the present invention to provide a combination marker-counter device, in the nature of a mechanical pencil or similar implement, which is adapted for marking and counting a number of symbols, items or otherwise, which is extremely simple in construction, durable and reliable throughout a longuseful life, and which can be economically manufactured for 'sale at a reasonable price.

It is still another object of the present invention to provide a marker-counter device having the advantageous characteristics mentioned in the precediitg paragraph, which is extremely compact, so as to be light in weight and small in size, for easy manipulation and convenient storage, say in a user's pocket, or otherwise on the user's person.

It is still another object of the present invention to provide a marker-counter device of the type described which includes a unique means to selectively preventoperation of the counting mechanism as desired, so that the solely as a marker.

While the marker-counter device of the present invention is illustrated and described herein asincluding a lead holder, in the manner of a lead pencil, it is appreciated that other suitable marking medium may be employed, for example a ballpoint pen cartridge, crayon, or other.

Other objects of the present invention will become apparent upon reading the following specif cation and referring to the accompanying drawings, which form a material part of this disclosure.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS DESCRIPTION OF THE PREFFRRED EMBODIMENT Referring now more particularly to the drawings, and specifically to FIGS. 1 and 2 thereof, a marker-counter of the present invention is there generally designated 10, and assumes the overall external configuration of a writing implement, such as a lead pencil, or the like. More specifically, the marker-counter includes an elongate hollow outer casing or housing I l, which may be of generally tubular, open-ended configuration having a laterally enlarged or protuberant mediinstant device may be used al portion 12 provided with a transparent window or opening 13, say having a magnifying glass closure. The outer casing 11 reduces, as at 14 in the upward direction from the laterally enlarged medial portion 12 to an upper end portion 15. Similarly, the laterally enlarged medial portion 12 reduces downwardly, as at 16 to lower portion '17 which, in turn, tapers or reduces downwardly, at at 18 to a lower terminal or end portion 19. The upper terminal or end portion 15 and lower terminal or end portion 19 may both be open, the former being closed by a closure cap 20 engaged over the upper end and removably fixed thereto by any suitable fastener means, such as a threaded fastener 21 extending diametrically through the wall of closure cap 20 and received region of terminal portion 15. The upper end closure or cap 20 is formed with a throughbore or opening 22, see FIG. 2, for a purpose appearing presently, and is further formed with a blind, downwardly or inwardly opening hole 23, which communicates with the interior of the outer casing.

Located in the laterally enlarged medial portion 12 of outer casing 11 is a counter device 25, which may be of conventional construction. Further; the counter device 25 may be provided with changeable numerical indicia, see FIG. 1, visually presented through the window 13, and afi'ording a record or count of items being counted. To reset the counter 25, say to 0, there may be provided a reset member or button 26, presented exteriorly of the outer casing 11 for manual operation by the user. Interiorly of the outer casing 11 the counter device 25 is provided with an operating member 27 movable to effect counting operation of the counter. In the illustrated embodiment, the operating member 27 is shiftable longitudinally of the outer casing 11, say in the direction of arrow 28, to effect each digital displacement or recorded count.

An inner casing 30 is located longitudinally of and within the outer casing 11. The inner casing 30 is of an openended tubular configuration, including a main portion 31 terminating in an open upper end 32 adjacent to and spaced below the cap 20. Extending downwardly from the main portion 31 isa reducing or tapering portion 33 adapted to conforrnably seat against the interior of the tapering portion 18 of outer casing 11. From the tapering portion 33 of inner casing 30, there extends a lower terminal or end portion 34 slidable within the lower terminal or end portion 19 of the outer casing. Medially within the interior of the main portion 31 of inner casing 30, there is provided an internal shoulder 36, and at one location in the upper end edge 32 of the inner casing 30 there is provided a notch 37, best seen in FIG. 3.

A resiliently biased elongate memberor plunger 38 may have an enlarged upper end of head 39 slidably received in the bore 23 of closure cap 20, its other end depending to a terminal portion 40 engaged in notch 37. Suitable resilient means, such as a compression spring 41 may be interposed in bore 23 resiliently urging the plunger 38 downwardly. Further, the plunger 38 serves to restrain inner casing 30 against rotation within the outer casing 11.

In alignment with the counter operating member 27, longitudinally within the outer casing 11, there is providedexternally on the inner casing 30 a lateral projection or extension 42 which is movable with the inner casing into actuating engagement with the counter operating member. That is, the inner casing 30 is shiftable longitudinally within the outer casing, in the direction of arrow 43 against the resilient restoring force of spring 41. Upon upward shifting movement of the inner casing 30 relative to the outer casing 11, the inner casing extension 42 engages with and shifts the counter-operating member 27 to.actuate the counter.

Disposed longitudinally of and within the inner casing 30 is an elongate marking means holder 45. The marking means holder 45 may be of a tubular construction having an upper end enlargement or head 46 slidable within the inner casing, and its lower portion split, as by longitudinal cuts 47 into a plurality of longitudinally extending fingers or tines 48. The tines 48 are resiliently expansile upon their extension outwardly with respect to the inner casing 30, and their retraction is limited by radially protuberant formations or bends 50. This construction of marker holder is conventional for holding lead in a variety of lead pencils, so that further description is unnecessary. While the marker holder 45 may be termed a lead holder hereinafter, it is appreciated that any suitable type of marker holder or marker per se may be employed and is intended to be comprehended herein.

A coil compression spring 51, or other suitable resilient means, may be employed to resiliently urge the lead holder 45 upward toward its retracted position relative to the inner casing 30, as seen in FIGS. 1 and 2. The spring 51 may be interposed between the collar or shoulder 36 and end enlargement or head 46 to effect the desired resilient urgence.

In order to extend or displace the lead holder 45 longitudinally outwardly, as in refilling or replacement of lead, an elongate push member or rod 52 extends slidably through the bore 22 of closure cap between the interior and exterior of the outer casing 11. More specifically, the push member 52 has its inner end extending downwardly through the open upper end 32 of inner casing into engagement with the upper end enlargement 46 of lead holder 45, while the upper or outer end of push member 52 may be provided with a finger actuating member or button. Thus, the push member 52 is manually depressible for sliding movement relative to the closure cap and outer casing 11 to displace the lead holder 45 longitudinally outwardly relative to'the outer casing 11 and inner casing 30, against the restoring force of spring 51.

In the counting operation, it is only necessary to hold the outer casing ll firmly, and depress downwardly with the lead holder 45 or held lead 49 engagingfa surface to be marked. This effects upward-shifting movement of the inner casing 30 and its received components relative to the outer casing, the extension 42 engaging the counter-operating member 27 to operate the counter. The coil compression spring 41 is compressed by this counting operation, and upon release of pressure, the spring 41 restores the inner casing 30 to its illustrated condition of FIGS. 1 and 2, preparatory to repetition of the procedure for the next count.

In practice the instant marker-counter device may be sufficiently compact and light in weight for convenient portability, say in a user's pocket, and for this purpose a clip 53 may be provided on one side of the outer casing 11, see FIG. 1, to releasably retain the device in a pocket.

When it is desired to utilize the instant device as a marker, and not employ the counting function, the inner casing 30 may be quickly and easily locked in its extended position of FIGS. 1 and 2, for use as a conventionalpencil, pen or the like. Toward this end, a leaf spring 55 may have one end fixed, as at 56 interiorly of the outer casing 11, the other end being provided with a lateral projection or detent 57. The leaf spring 55 extends longitudinally within the outer casing 11, and the inner casing 30 is formed with a radially outwardly facing recess or hole 58 located in alignment with the detent 57 when the inner casing is retracted. The outer casing 11 is formed with a slot 59 extending longitudinally along the lower region of leaf spring 55, and a locking member or slide 60 is slidable in the slot 59 as between the upper position of FIGS. 1 and 2 and the lower position of FIG. 4. In the upper position of slide 60, the leaf spring 55 is undeflected, and the detent member 57 is retracted outwardly away from the receiver hole 58 of inner casing 30. However, upon downward shifting movement of locking slide 60 in slot 59, the slide displaces the lower end of leaf spring 55 and its carried detent member 57 radially inwardly to interengage the detent in the opening 58, the condition shown in FIG. 4. In this condition the inner casing 30 is effectively locked against longitudinal shifting movement, so that the device 10 may be employed as a conventional marker.

From the foregoing, it is seen that the present invention provides a marker-counter device which is extremely simple in construction for economy in manufacture and reliability throughout a long useful life, and otherwise effectively accomplishes its intended objects.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention.
