MEASURING TAPE.

Application filed. May 12,

My invention relates t8 tapes for the use of surveyors, mechanics, inspectors, and others, and is concerned more particularly with the terminal element usually referred to as the ring. When two persons cooperate in using a tape no difliculty is experienced because one person can hold the end at the point where it should be while the other measures oil the distance. But usually tapes are operated single-handed, and it then becomes important to provide means for holding the free end of the tape in place while the operator measures out the distance or passes to the other end' of the object to be measured. 1

The general purpose of my invention is to provide an advantageous form of anchor or holding device for holdingthe free end of the tape in place while the operator moves to a distance to take the measurement. One of the specific and contributory objects of the invention is to provide an anchor which will take hold of a flat surface in the plane in which the measurement is to be taken. For example, in the case of a floor it is my purpose to provide two prongs which will stick into the fioor so as to holdthe tape-- end anchored at the point where it is placed. Another object is to provide a construction especially adapted for driving the prongs into a wood floor, or the like. I accomplish this by forming shoulders on the prongs whichwill absorb the blow of a hammer or other striking object. Another object is to provide an anchor which will securely hold the end of the tape conterminous with the end of an object being measured. For example, where a board is to be measured, I have provided means for engaging the end of the board for holding the free end of the tape in place. The prongs are two in number so they will balance each other and keep the tape ring squarely in place. Also they are so constructed they may either be driven into the end of the board or will take under the board or under a metal plate and grip it and thus ensure that the ring will not ride up and over the end.- Another object is to provide a construction such that the anchor may be folded or swung into the plane of the ring and when thus folded Will hold itself in place. A further object is to provide a foldable anchor which when folded will not interfere with the ordinary use of 1926. Serial No. 108,471.

the tape. This and other objects will become apparent as the description proceeds.

I obtain my objects by the mechanism illustrated in the accompanying drawings, in which F lgure 1 is a perspective view of the complete tape and its casing, the terminal ring being shown right side up. I

Figure 2 is a perspective view drawn to an increased scale showing the ring bottom sideup with the anchor in folded position.

Figure 3 1s a perspective View of the terminal ring and anchor showingthe ring right side up and the anchor in extended or operating position. i

F1gure is a cross sectional view of the ring showing the anchor in folded position.

Figure 5 is a longitudinal sectional view of the ring showing the anchor extended and in operating position against the end of a board, metal plate or similar object. In this view the side prongs engage under the bottom of the board or plate.

Figure 6 is similar to Figure 5, but shows the side prongs entering into the end of a board.

Figure 7 is a bottom plan view of the parts shown in Figure 6, the anchor, however, bemg in folded position.

Figure 8 is a bottom plan view similar to Figure 7, but showing a modification in which the anchor is pivoted to the ring by ears that are located on the outside of the ring instead of on the inside thereof.

Like numerals denote like parts throughout the several views,

Referring first to the form shown in Figures 1 to 7, inclusive, the tape 10 which may be of steel or any other suitable material, is provided with a casing 12, in which it is stored when not in use. The tape proper and its casing are not intimately concerned with my present invention, and hence need not be described in detail. Atthe end of the tape is a sleeve 14: havmg cheek plates 16 by which it is riveted or otherwise fastened to the end of the tape. This sleeve forms a pivotal bearing for the ends 18 of the terminal element 20, which, for convenience, I shall refer to as a ring, but which, according to the illustrated design, 1S oblong or approximately rectangular in outline. 1

The anchor or holding member has a pair of care 22 which pass to the inside of the sides-of the ring and are pivotally secured thereto by pins 24. The anchor has a pair of shoulders 25 whichabutthe end of the v ringto hold the anchoratright, 'angles'to the plane of the ring'when the anchoris acting. The anchor also has a pair of prongs 26 that are sharpened atthe end and connected by Said. cross bar. holds the a cross bar 28. prongs in spaced relation and is located ap- C proximately midway between the ends of said prongs, thus imparting to the anchor a form somewhat similar to the letter Hi.

' Extending inward from'theprongs 26 are supplemental prongs 30 capable of engaging the end of a board or object along which the tape is to be laid. Except for the ears 22 and prong 30 the anchor orholding member lies-chiefly in a plane, with the result that when in folded orclosed position, as shown in Figures 2 and 4, for example, said anchor will lie fiatagainst the sides of the ring. In the form shown the sides of thering are approximately round in cross -section,'and

the prongs 30 are spaced slightly farther apart than the normal inside measurements of the ring. The result is that when the anchoris being folded, the prongs 30, as

they come'intocontact with the rounded.

surfaces of the ring, are wedged together slightly, thus setting up frictional engagementwhich holds the prongssufficiently to. enable the anchor tomaintainits closed or folded positionwhen not in use. -The ring is also of slightly resilient metal so that the sides can yield outward slightly -asthe prongs come into engagement with the sides of the ring. Thus the anchor maybe readily folded and unfolded but when in folded position iscapable of maintainingitself in such position, and when in such position is outof the way and does not lnterfere with the ordinary use of the ring; Prongs 30 are not-long enough to project above the top of the" ring, and hence there is no danger of their becoming caught i anything when nchor is folded. v

' In practice, if it is desired to measure. a long wooden floor, for example, the tapem'ay be anchored to the floor by moving the anchor to the open or extended position,- as

shown inlFigure 3, and tapping the ring 'user moves away a distance to take the measurements. If it is desired to measure a slightlyto drive the prong 26 into the wood.

As the end of the ring bears directly against the shoulders 25, the latter absorb the blow,

thisrelievingthe rivets 24 of any strain.

This will hold the ring in place while the piece of timber, as for example, the piece 32, shown in Figure 6, the anchor may be adjusted to the end of the piece in the mannerillustrated, after which by tappingthe;

prongs30 theymay be driven into the piece, thus bringing the plane of the anchor adjacent to the plane at theendof the piece, after which the measurement may be taken intheus ual manner. If it is desired to measure a metal sheet, the anchor is adjustedas shown'in Figure'5. "The flat or horizontal uipper edges ofthe side prongs 30 engage the under surface of the object and prevent the anchor from slipping up and off. Thus the anchor bears squarely against the end of the object and holds the tape correctly conterminate with the object. If the anchor is not to beus'ed, it maybe folded to closed position, and the ring beused in the usual manner. As the cross bar 28 1s at a distance from the pivots 24: it will, when folded, be

pass to the inside of the side bars of the. ring, this s not essential, for they may pass to the outside, as shown bythe cars. 22,

shown in Figure 8. v i I From the foregoing it will be evident that my device is simple in construction, and yet affords ready means by which the terminal ring may be held in place to enable an operator to use the tape without assistance.

\Vhen the-anchor isfolded it occupies little space, and-in no wise interferes with the ordinary operation of the device.

Having thus described my invention what I claim as new and desire to secure by LettersPatent is:
