. iMPRovl-:MENT IN TAPE-MEASURES.'

Specilication forming part of Lrtters Patent No. 92,573, dated Ju1y13, 1Sl69; reissue No. 4,419, dated .Tune 13,

l `Be it kno'wn that-I, LEWIS P.v BRADLEY, of New Haven, in the county of New Haven and State of Connecticut, have 4invented a new Improvement in ',lape-lleasures;y and I do hereby declare thatthe following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and .exact descriptionof the'same, and which said drawing con-l stitutes part of this specification and represeuts, in 1 Figure 1, a side view; Fig. 2, a transverse section; Fig. 3, alongitudinal section; and in Fig. 4, a transverse section, the'central portion enlarged.

This invention Arelates to an nnproveinent in tape-measures such as are constructed for self-winding-that is, so that the tape pulled ,out will be returned by the reaction of la spring within thecase 5 the object of the invention being an arrangement whereby the action ofthe spring may be arrested at any desired point, and hold the tape when withdrawn,so as to prevent its being .rewound within-the case.- To this end the invention consists in the arrangement of a central knob or'rbutton in one side' of the. case, towhich is fixed upon the inside of' the casefa. bar, so that h f pressing the knob inward lthe bar is raised from a. notch or notches .on the spring-cylinder to permit the action of the spring, so that when the pressureis removed4 from the knob the .bar will fall into a notch' -orcatch onthe cylinder and prevent the reaction of the spring.

The object of arranging the knob or button for working the holding and releasing de-.

vice in the center of the side of the case is t0 have it 'in such a positionthat, when the:

case is held by the thumb and finger of one hand for hand, the utton may betakenj by one or the other, (the finger or thumb so as to be ina-l nipulated for releasing vthe spring or Acatchclaiming a self-winding tape-measure, as such,

ing it.. l

ijln'order to the, clear 4understanding of my Eulling out the vtape byfthe 'other invention, I will fully describe the same as l illustrated in the accompanying drawing.

' A is the case, within which vis arranged a spring-cylinder, B, operating so that the tape is wound upon the outside of the cylinder by the action of the spring within. One side of the case is constructed so as to extend inward andform a bearing for the support of 1 the action of which spring is to force the knob outward and the bar fonto the cylinder, as seenl in Fig. 2, in' which position it engages with one of the notches a, as seen in Fig. 3, and prevents the reaction of the spring after the tape has been withdrawn but when itis desirable to draw in orrewind, the'tap'e, press the button D-inward, which forces the bar f1 from the notchou the spring-cylinder, as seen in Fig. 4; then the spring will react and Vwind the tape. i

It will be seen that, on account of the case being oval on the sides, it will most naturally .be grasped by the .thumb and lngerat the center fo'r being. held while pulling out the tape or'guiding it back again-in fact, it canf not well-,be heldin this Way without. There-V fore, if the button be arranged inany other position it will be diihcult, if not impossible, to `so holdy the case, and, at' the same time, manipulate it; whereas in this arrangement it is done with the greatest ease, especially if a knob or stud, D', be placedl in the center of the-opposite side, as I propose to do, which, together with the button, .formtw center pivots by which the case is .suspended between I am aware, is not new; but

WVha-t I do claim as my invention, and de- 2. The knob for actuating thc holding und sire to secure by Letters Patent, isreleasing catch, arranged in the center of the 1. The arrangement of the spring-cylinder case, substantially as specified. B wit-hin a c'ase, A, combined with' a knob, D, arranged through thebearing of the cyl- Titnessesz indcr so as to operate the bar f, the whole GEO. W. MABEE, operating in the manner herein setforth.
