Oct. 4, 1949, o. M. BRATRUD GLUE SPREADER AND PAPER CUTTER Filed Dec. 22, 1945 Patented Oct. 4, 1949 UNITED STATES PATENT FMC@ 1 Claim. l

This invention relates to glue applicators and paper cutting instruments. More particularly, it has reference to a combination tool or instrument embodying therein, at one end, a glue container with novel glue spreader cap, and at its other end, containing an adjustably mounted blade that is especially useful for the cutting out of parts from the pages of magazines and newspapers.

It is the principal object of this invention to provide a combination instrument or tool embodying the features above mentioned, that is especially adapted for the cutting out and securing of newspaper and magazine clippings, for eX- ample,` an instrument that is especially useful in the making of scrap books and the like.

It is also an object of this invention to provide such a tool that is in the form of a pen or pencil and is equipped at one end with the cutting blade and adjustable means that determines its exact cutting depth, and is equipped at its other end with a novel glue spreader cap to which, in use of the device, glue will be supplied from a. chamber in the barrel of the device.

Another object of the invention is to provide an instrument of the above stated kind comprising a hollow barrel that may serve as a reservoir, or container for glue and on the end of which barrel is fitted a flexible glue spreader cap hav- .fing novel features of construction.

Yet another object of this invention is to provide the present instrument with a paper cutting blade that may be adjusted by relative rotation of the barrel for cutting to any designated paper thickness.

Still further objects of the invention reside in the details of construction of the various parts embodied in the device, in their combination, and mode of use as will hereinafter be fully described.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Fig. 1 is a side view of a combination glue applicator and paper cutting instrument embodied by the present invention.

Fig. 2 is a longitudinal section of the same, taken on line 2--2 in Fig. 1.

Fig. 3 is an end view of the instrument, showing the paper cutting blade.

Fig. 4 is an upper end view of the glue applying cap.

Fig. 5 is a cross section on line 5 5 in Fig. 2.

Fig. 6 is a sectional detail showing the use of the glue applicator. l

Referring more in detail to the drawings-v l designates the present tool, or instrument, in its entirety. In its present preferred form of construction, the tool is of such size and design that it may be carried in the vest pocket after the fashion of carrying a fountain pen or pencil.

As shown best in Fig. 2, the tool comprises an elongated barrel portion l0, tubular in form and open' at its ends. Intermediate its ends, the tubular body is formed with a partition Wall, as at l2, that sets off a chamber I3 in the upper end of the barrel for containing a supply of glue, as designated at I4. Formed about that end of the barrel is anencircling shoulder, or a'nge l5 and removably applied over the flange and serving as a closure for the glue containing chamber, is a rubber cap i6 that is designed for use as an automatic glue applicator.

The cap I6 is cast, or moulded, or rubber, and it comprises a tubular body portion, open at one lend and adapted to have that end portion slipped over the end ange l 5 of the barrel. It is formed internally, adjacent that end edge, with an annular groove designed to receive the iiange l5 of the barrel therein to secure the cap against accidental displacement in use. I

The outer end of the tubular cap I6 is closed by means of an end wall 20 that has a flat outer surface inclined at an angle of 45, o-r approximately at that degree relative to the axis of the tube. The end wall 2D is formed with a straight slit 22 extended thereacross and therethrough. As observed in Fig. 4, this slit is located about midway of the axial center of the cap and its peripheral wall.

In the particular design of the wall of cap I6 resides one of the important features of this invention, and this design is best brought out in Figs. 2, 5 and 6. By reference to the showing in Fig. 6, it will be observed that the side wall of this cap which is of shorter length by reason of the inclination of the end surface, is relatively heavy and thick, while those side walls which are adjacent the ends of the transverse slit 22 are relatively thin, as is also the outer end portion of the side wall that is longest by reason of the inclination of the end Wall.

The fact that the side walls, designated in Fig. 5 as S and S, and the front wall portion f, are made thin and relatively exible, while base Wall b is relatively heavy and rigid, insures that when the end surface 0f the glue applicator cap is applied against a surface after the fashion illustrated in Fig. 6, the rubber will ex at the proper places to cause the slit to open for the outflow of glue.

It is to be explained that by placing the applicator against a surface as in Fig. 6, and then drawing it along the surface in the direction indicated by the arrow while an intermittent down pressure is applied, a pumping action will be produced that will cause small amounts of glue to be discharge'dto the',l surface, then bym'er'eily using the cap as a brush, this deposited glue"v can be spread over the surface. The flexibility of the rubber cap causes the slit 22 to close tightly when down pressure is removed. y Y It is observed also, in Figs. 2 and 6, that the edges of the slit are rounded oi, as latf-THJ, soa's' toi f permit free and easy outflowioiglueWhenfthefslit is open.

In conjunction with the glue spreaderor'applicator, I have equipped the device with a paper --cutter which is.-in.the.naturelof.r an improvement upon the device of my prior Pateni'flo-l 1;755,535, issued April `22,',1930s Byyreferenee more Aparticularly to:=F.ig,-2,"it Will be netedfthat'an ex-tension member `35-i-s threaded intthatrendeo theebarrel that is opposite the glue applicator` This extension is tubularandfis eqnipped Witma'tapered-outer; end portion 35a that,is. -.formedfwith an axial-,f slotor: passage'` 36 that epenszintofthe externally threaded, 'tubular portionpfthesaid:extension-:member: Locatedt-in thisfextension' member isla-,flat bara?, the router endportion, of which is-,s1idably=containedin' the slot; while the inner: endportion ,extendsfsomewhat from? the inner 'end-'ofthepart 35s and is i equipped .atrits V end fWi-th across head; 38 Ythat AengagesagainstthepartitienWalll 1211er the tubular barrel.:`

A very desirable feature in this provision for adjustment is that the blade can be so accurately adjusted as to limit its cutting depth to the exact thickness of one sheet of paper which is very desirable in cutting clippings from newspapers or magazines. The blade will be retracted When the barrel is threaded upwardly by the spring pressure.

Such devices may be made in various sizes, lengthss-proportions and of various materials.
