rRINrIiie-rnnss GAGE.

Specification of Letters Patent.

Application filed October 18, 1916. Serial No. 126,293.

T 0 all whom it may concern:

Be it known that I, EDWARD L. MEGILL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Printing,

so that they may be properly presented to the type. I have in mind particularly the sort of gages in which there s one part that is inserted through a hole or slit in the tympan sheet, and lies below this sheet, and another part connected to the first part when it overlies the tympan sheet, the sheet bein gripped between these two parts. Gages'o this type are usually provided with a tongue which projects through an openlng in a vertical head member continuous with the part that overlies the sheet, said tongue member having side walls or extensions engaging the member that overlies the sheet, and along which the tongue member is slidable. It has been customary to provide stops limiting the sliding movement of the tongue in the direc tion away from thehead member, and with such a construction it is obvious that difliculty would be experienced in case the tongue were broken or in case it were desired to replace the same by another of different length. Or, if no such stop were provided'the tongue member might be jslid' too far until'it came oil, in wh ch event there would be difficulty in putting it back into position, and likelihood of injuring the fingers on the exposed end of the prong.

Accordingly, one of the objects'of the invention is to provide a gage of the kind referred to, including ahead member having a vertical wall provided with an opening, a prong member extending from said head member and adapted to be inserted beneath the tympan sheet, an upper pressure member extendingfrom the head member in the same direction as theprong member, and a tongue slidable to different positions along the upper pressure member and extending through the aperture in the vertical wall of the head member, said upper pressure memher having a stopportion for normally lim-v iting the movement of the tongue in one dlrection, and said pressure member being constructed to permit of the release of the tongue from the restraint of said stop when it is desired to replace the tongue in case of breakage, or to substitute a tongue of different length.

Another object is to provide a construction of tongue which in itself will afford elasticity and adjustability in the parts connectlng it with the upper pressure member of the gage pin, so that it will hold with proper tension to the parts of the upper pressure member to which it is attached, even though these parts should not be ex- Patented July 26, 1921.

actly true or regular, thus providing .a

tongue that will be interchangeable from gage pin to gage pin.

Another object isto provide a construction of upper pressure member including two parallel arms connected at one end and yieldable toward each other at the other end, with the tongue member slidably engaged with both arms.

A further object is to construct the free ends of the parallel arms with fingerpieces extending at right angles to the plane of the arms, whereby they may be engaged in the operation of pressing them together for the release of the tongue; also to so shape the arms that their free ends may be pressed very close together, notwithstanding that their fixed ends are comparatively widely separated.

Other objects and aims of the invention, more or less broad than those stated above,

together with the advantages inherent, will be in part obvious and in part specifically referred to in the courseofthe following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and

the scope of protection contemplated will appear from the claim. j v

In the accompanying drawings, which are to be taken as part of this specification, and in which I have shown a merely preferred form of embodiment of the invention, Figure 1 is a perspective View of a gage pin embodying the invention; Fig. 2 is a perspective view of the; tongue portion, detached; Fig. 3 is a top plan vieW of the article shown in Fig. 1; Fig. 4 is a sectional view taken on the line H of Fig. 3; Fig. 5 is'a sectional view taken on'the line 55 of Fig. 3; Fig. 6 is a bottom plan view of the subject-matter of Fig. 3; Fig. 7 is an end view of the subject-matter of Flg, 3, looking toward the right Fig-8 is a view similar to Fig; 6 but showing the adjustable.

tongue inanother position; Fig. 9 is a view simllarto Fig. 8 showin the tongue in still another position and straint of the stop; and Fig. 10 1s a rear" reed from the reend view of the tongue, detached. g

7 Referring to the numerals on the draw- I ings,=there is shown at 11 aprong part having a bentend 12 so that it may be readily inserted through the tympan' sheet, making an aperture therein for itself. 'At its other end .thisprong part 11' is connected to or integral with the usual vertical headportion 14, and zalso connected to or integral'with this head portion 14 is an upper pressure member comprising two parallel arms 15,

one .oneach side of the prong portion 11,

normally spaced apart. in .a predetermined relationtbut movable toward each other under pressure. These arms 15 are preferably integraliwith abridge 16 continuous with butat-right angles to the vertical head portionil4, and the arms 15 are joined to this grippedbetween the prong portion 11 and the upper arms 15, frictionally, to hold the gage againstmovement, the free end of the prong portion 11 extending upwardly toward:;the arms .115 at an angle,'as shown in Fig.'.5.- When the gage is in thedesired ad justed; position, pressure is applied to the bridge-11.6, to drivepdown-into the tympan sheet, the points 18 which are formed on the'vertical head member 14.

The tongue member isshown in perspectiveiin Fig. 2 and inv end view in Fig. 10;

When'the V, tonguejs-inposition, with one end projectingthrough the aperture 20, the hooks 22 are supposed to be engagedgover the edges of;

the flat garms' 15: It isjev'ident :that the tongnei mayjnowbe adjusted so as to project; la; greaterj or "less extent through the opening 20, -('c'ompare,Figs3 6, 8 and 9). In orderto:;facilitate this sliding? adjustment of the.tongue theiendthereof, that is the end of the part 21 betweenrthe hooks 22, is bent up sharply at rightangles as indicated at 24:

to provide a 'fingerpiece. When the tongue I memberispushed toward the left (referring to Fig. 1) it is evident that its limit of movementin that direction is fixed by the inclined parts 17, which act as stops; and in order to limit/the movement of'the tongue in the other direction, that is to the right in Fig. 1, the arms 15 are provided with down turned side flanges 25, pastwhich the hooks could not move except for the fact that on account of the resiliency :of the material'of whichthe device'is made, particularly the arms15 and their connection to the bridge 16, the free ends of the armsmay-be moved toward each other, through theirjnormal tendencyis to. spring apartv tothe position? shown in Fig.8. It is evident that as the j tongue. member'is slid fromjth'e Fig. 8 po sition to. the Fig 9 position,these hooks will exercise 'a frictional hold .upon'the arms, 1 thus assuring the retention ofthfeftongue 1n any position to which it may be brought, and compensating for slight irregularities in size of parts, etc. To remove, thetongue part entirely it is necessary merely to grasp the e 7 ends of the arms 15 and exert pressure against the flanges 25 suflicient to force the free ends of the arms'more closely together.

to such an extent that one or both of the books 22 may be disengaged from about the edge portion or portions of the-arm. or-arms' 15 (see Fig. 9), whereupon the hook end of the, tongue may be lifted up and the other end entirely withdrawn from theopening 20 for purposes of repair or replacement or substitution. In replacing, the, tongue end .is first pushed through 'the opening 20, be

neath the bridge 16,and then the free ends of ;the*arms '15 i are pressedfitogether suiiiciently to allowof the engagement of the V hooks 22with the edgesof and underneath thea'rms, whereupon the pressure uponv the arms 15 is releasedand the edges of the arms snap 1111130 the hooks and hold themselves by friction, as already described, The hooks 22 are so shaped and-so joined'to thepart 2].-

The downturned flanges 25 on the outer edges and at the ends of arms 15 have the effect of keeping the ends of the arms above and spaced away from the tympan when the device is in use. With prior devices of this kind, in which the ends of the arms rest on the tympan sheet, the effect was to produce something very like a shearing action on the tympan sheet, especially if the latter were thin, between the edges of the arms on the one hand and the edges of the prong on the: other hand. Incidentally, these vertical flanges 25 serve as finger-pieces for compressing the arms toward each other. If the arms were not provided with a flange the arms, especially if bent downward at the ends, would be likely to twist in the fingers under pressure, besides giving pain and discomfort.

Furthermore, these flanges 25, because of their location, permit of a considerable extent of movement of the arms toward each other without striking the prong. And they serve as stops, to prevent the hooks from sliding off the ends of the arms.

It will be evident that I have provided a construction in which the adjustable-tongue will be held in any adjusted position; from which there is no danger of the tongue accidentally slipping off and getting lost; and from which the tongue may be removed for purposes of repair or replacement, when desired, without inconvenience and danger of injury to the fingers.

Inasmuch as many changes could be made in the above construction, and many apparently widely, different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claim is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim: 7

In a device of the kind described, a head member having a vertical wall provided with an opening, a prong member extending from said head member and adapted to be inserted beneath a tympan sheet, parallel flat arms extending from the head member in the same direction as the prong member and normally spaced apart in a predetermined relation but movable toward each other under pressure, and a tongue member slidable above and to diflerent positions along said arms and having turned-under hook portions engaging the edges of and beneath the arms when the arms are in their normally spaced relation, said arms being movable toward each other under pressure a sufficient distance to permit of the engagement of the turned-under hooks with the edges and under sides of the arms, or the release'of the hooks from such engagement, said tongue member being located intermediate the arms and the spaces between the arms and the tonguebeing wider than the length of the hooks, said arms at their free ends having downwardly turned side flanges on their outer edges serving as'finger pieces to move the arms toward each other and also acting as stops to prevent the hooks from sliding off the ends of the arms.

In testimony whereof I aflix my signature.

EDWARD L. ME GILL.
