To ALL wHoM 1T MAY ooNenRN:
Be it knownthat I, SAMUEL DARLIG, of Bangor, Maine, have invented an Improved Device for an Attach Yment to the Levers or'Handles of Vises, to hold'thesnme in position and I do hereby declarelthat the following, taken in connection with the drawings which accompany andform part of this specification, is a. description of my inventionv suicient to Aenable those skilled in the art to practise it. l
The handles or levers which `pass through the heads of vise-screws, forthe purpose of opening'and closing the'vise by turning the screw, are at liberty, as -u-sually constructed, to slide freely in the vise-head. This v freedom of motion is desirableJ for the purpose. of' varying the leverage, but, if it slide too freely, the handle is not only likely, when-suddenly released by the workman, to drop quickly,'and so endanger his ingersbut this sudden motion also frequently, by reason of the weightand vchange 'of position, and the jarring produced vby the' handle, loosens or tightens,'beyo'nd the degree required, the hold of the vise upon the article held, so that, if it be smallit'is apt to drop to the door, arid, if it be ofcom'paratively soft ma'terial,`it is' apt, bytoo/A great pressure,..to be compressed out oi`- itstrue shape.
To remedy these and similar glefects, and to avoid Snell-.,annoyance's, somewhat expensive contrivances have been adopted in the original manufacture of vises, but whichwould be almost impracticable if sought to be 'applied by a workman to'his common form of vise-already in'use upon his work-bench.'
One of these contrivances consistsiin the cutting, by a very didicult and costly process, of an oblong'ispace within the head of the vise-screw, and in .line with the bore. through which the handle passes, and connecting with the same. An arched piece ot' metal, serving *to act as la., spring, .bears against one 'of the walls of this oblong chamber, and also against thehandle, to. hold it with suiicient forceto prevent its sliding. `Such a provision is costly, vdifficult .tobe, made, has no'mode of'adjusting the pressure Yto meet the wear, and cannot be readily applied, at short notice, to any common vise. i
Anotherimodehas been devised, by which the same 'end is' accomplished, but with a provision for adjust* ment, and is as follows: A hole isdrilled in the head of the vise-screw, and in line with its-axis, and communi-- "eating with the cross-opening in which the handle plays. Within this hole is placed a washer or piece, bearing upon the handle; and a Yscrew'is vfitted in the hole, a spring being interposed between the washer and thisscrew. The-screw affords the means for adjusting the pressure of the washer upon the handle.
Whilst this mode is preferable to the first-mentioned, being simpler, and under'eontrol, yet it has, in comf monwith it, the great disadvantage of not being applicablefto the common vises in every-daynsein machin@ shops, without the expenditure of much time, labor, and expense.' B'ot'h these plans require cavities to be made inthe head ofthe vise-screw. It is, therefore, important to avoidthislabor,and provide a means for attaining the same end without altering either the vise-screw or itshandle, and `to hold the handle by devices which act v upon it entirely outside of the'head of the screw.
I will now proceed tovdescribe my appliance'for this purpose. V
Figurev 1 represents a viserscrew, and its ordinary handle or lever, with my improvement applied thereto;`
Figure 2 represents an end view of my novel device, ,exhibitingthe ,two parts which grasp the lever,and I one of the screws which connectthem. l
Figure 3 represents another method of accorri-pli'shin1g the same object by means o'asingle spring, which pulls or dr'aws'against the handle. I
Figure 4 isa view of said spring audits liooked'ends beforebelng bent end applied to the handle.-4
A is the head of the vise-srew,l3 its handle, of ordinary construction, and C my novel device. This device is composed of two parts, 1' and 2, held together, when placed on the handle','by screws, as shown. The thicker of the parts 1 2 ,1 prefer to make of'malleable iron, andthe thinner one I prefer to punch out of steel, end then form it in a press. I construct ench piece'of such form that'it'may span half around the screwehead, and with its ends so bent that each may nearly half span the 1ever. The two pieces, being then laid face to faces, should coincidein their outlines, except thattheir curved ends cn-riiein directions opposite each other, so p as to form nearlynfring or band, to envelop-e the handle. Voneuch side of and close up to' the sci.ew-l1ead.. The two nieces, being first 'screwltapped for the purpose, are then held together by screws with suiiicient tightness .to grasp the handle, so that it may not loosely `slide therein. The screws also allow the parts to be tightened,
. pose described.
as may be necessary, to meet `any wear. y
rIhe simplicity and cheapness and perfect eiliciencyof this contrivance can hardly be overestimated. They can be made rapidly, applied to any vise in a few minutes, at a triling expense., Neither of the other appliances above hrst described can' be adopted in an old vise Withoutincurring` greater labor and expense than the improvement will warrant. With my plan, however, my'device may be constructed as an independent article of manufactlire, adapted in size to all the known sizes of vises, so that from any part of tlie world they may be ordered, and the order lled, by simply sending the size of the screw-head. and lever, v 1
Another very sim-ple form for eil'ecting the' same endfbutnot so practicable,pwould be to wind a piece of wire around the h andle on one side of the screw-head, and thencarry it aer'oss the head, and Wind it around the handle on Atheopposite side. y
Itis evident that other metals, as Well as malleable iron and sheet steel., may be used to make m y new improvement. V l
i It will be observed that all the pressure' exerted by my apparatus, above described, is expended upon the lever, and not, as in the other cases, partly upon the lever and partly upon the screw-head and, further, my device is entirely outside of the head, whilst the previously-known contriv'ances are-entirely within it.
Another advantage incident to my device is that its size, form,1and weight are such that it may be conv veniently transmitted by mail, in an envelope, to any part of the country, and at cheap postage-rates, being all ready when received to be immediately applied to use. v
In the modificationshownin ligs and 4, (but which isV not so desirable as themode of lconstruction shonn in Iigs. I and 2,) I employ aat spring, both'ends of which are made of hook-form, as shown; land it is applied Ato the vise-handle by bending it around the scren'fhead, and hooking each of the hooks to the handle, one on either side-of the head. The spring should be so formed that itseentre shall touch or bear up'onithe head, and thus produce the necessary pressure upon the handle; or this spring may be made to press upon the handle by a bolt passing through the spring and screwing into-the head, or by a set-screw passing through the spring as a nut, and pressing against the head. p l' y i v Another modification would beto attach a ring to the handle on each-side of the head, withsuljcient spring or friction to hold the' handle in any given position, and yet'capable of being slidden upon the handle, as occasion may require. v v
Instead of making the device C with two clasping-ends, asin' .figa-re, it may be made with one only, so'as to grasprthe handle atene side only of" the screw-head. In such case'it would extend only a little beyond the tip of the screw-head, and would be held and adjusted there by ascrew entering thefhead at its axis.
The dat-spring modification., instead of having two hooked ends, as in lig. 4, may have a hole -in eachiend, through which the handle may be passed. Its action wi'llbe about the same.
I claim a vise-handle holder,'constructe d and to be applied to the handle substantially as andfor the vpur- SAMUEL DA'RIIING.
