nLlPHALn'rs. scnrrfrunn', or BnooKLYN'n. Dl, NEW -ronlc Letters Patent No. 109,949, dated December 6, 1870; antedated November 25, 1870.
IMPROVEMENl lN WRENCHEVS.
The Schedule referred to in these Letters Patent and making part of the same.
t To all whom it may concern:
- Be it known that I, ELIPHALnr SORIPTURE, of the city of Brooklyn, E. D., in the county of Kings f and State of-New York, have invented an Improved Mode of Constructing, Applying, and Managing a Paw] when applied'to a Notch o r Tooth-.slide Wrench; and'I do declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings and to the'letters of reference `marked thereon. 1
The naturerof my invention consists in applying a strong pawl or dog, within the sliding-head cavity under av notched wreuch-bar,'i such a manner as will -render ityeryl strong,- reliahle, vibratory', adjustable, and readily removed. for repair or adjustability; in such a manner that sha-ll regulate the space betweenv the heads or jaws to a halt' notch when required for any specific purpose; in such manner as is extremely simple aud cheap, Awhile the `pawladmits' (in its use) ot asingle tooth, by which means finer teeth are admitted in' the wrench-bar, and more likely to be kept in order thereby.
To enable those skilled in the arts to make and use my invention, Iv will proceed to describe its construction.
I construct my pawl in a tlat, tapering shape, with astrong head for the notch-tooth and chinC-shoulder,
as shownin drawings.v y
Figure 1,letter A, thc'tooth, and B 'the chin-shoulder, which may be seen also in Figure 2; showing au open sideelevation of the slide head back as far as the springarm G; showing beneath ita portion of spring g l as resting against the back, andof the slide-head neck, 4marked letter C; showing at D an open space, ready to receive the metal slip de', the thickness ot' which is about one-half the amount of space between the teeth 'or notches in the-bar, which shows a cheap and simple alternative of regulating the space between the heads or jaws, fornuy special required purpose, without re- Y sorting to the expense of a screw and uut-pawl, as
shown in my patent of April 15,1858, for a like purpose.
The tapering body or tail of thc pawlhead` A'aud B rcststlat upon the bottom of the space in slide-hcad 4C, passing entirely through ,the same, and secured there by means of screw, letterE, shown atv the under sideI of lneck C, which screw passes'through au bblong hole therein, screwing into the pawl-steln or .tail F, securing the same thereto, allowing it to be slid forward or back just enough to insert or remove kthe regulating-slip di between the chin B and end of' 'ueck G, (where may be seen the slip-space, marked 1),) thereby varying the space of half a notch when needed.
Figure 3 gives a sectional side view of the slip di, which may be of any shape to best suit the purpose.
y The shape of this one shows a projecting nib-at each end, shown at c e, for the purpose of st-riding down over the projecting table or shelf, marked j', showing itself under space D, thereby securing it laterally until screw E is loosened sutticieut to allow Ythe pawlhead A a-nd B to rise far enough to insert or remove the slip.
The advantages of a speedy not-ch and pawlwrench i over those depending wholly upon a screw movement are both apparent and; important; and one'peculiar advantage I claim by-this arrangement is the allowanceot' aner and yet more durable notch or tooth in the bar, which are marked H H, &c. I claim it will be lnore durable on account of the tendency .ofthe single' pawl-tooth to work itself into the bottom of the notch when in use; further, that, it' by any chance the pawl-tooth B falls too far below the bar-teeth H H, 85e., a slip ol' metal or paper may be slid under pawl-stem F, in order to remedy the difficulty; further, that by slightly loosening screw E, the pawlhead A becomes slightly vibratory, which. lhas the eifect of retaining the paWl-tooth in the bar-notch.
H when turning the wrench backward While in use; further, that by having the pawl a detachable section of the parts, it serves the convenient purpose of a llct by which to regulate the slide-head space for the reception of thebar H; and further, by its tapering shape, it can be removed and' replaced without dis` placing the wrench-handle for that purpose.
