UNITED STATES PATENT OFFICE LUMAN V. "JACOBS, OF WARREN, MASSACHUSETTS.
M lTER-BOX.
SPECIFICATION ing drawings, is a specification sufficiently 7 my improved miter-box.
full, clear, and exact to enable persons skilled in the art to which this invention appertains tomake and use the same.
The object of my present invention is to provide a miter-box which shall be practically efficient for the purposes intended and conveniently adjustable for cutting different angles and for varying and gaging the action of the'saw as required in different classes of work, and which can be manufactured economically.
Another object is to provide a miter-box adapted for use with the ordinary different kinds of saws commonly used by carpenters in general work, and in which coarse or fine saws can be employed with equal facility.
These objects I attain bymechanism the nature and operation of which is explained in the following description, theparticular subject-matter claimed being hereinafter definitely specified. I
In the drawings, Figure 1 is a plan view of Fig. 2 is a front view of the same. Fig. 3 is a transverse vertical section on the line 00 cc. Fig. 4 is a bottom view, and Fig. 5 is a view showing the clamp for holding the adjustable saw-guide.
In referring to parts, A denotes the supportingframe; A, the upright back plates, which are preferably formed integral with said frame A; and B the bed or work-table, formed of wood or other suitable material and attached to said frame by screws.
0 indicates an adjustable overhanging arm or guide-standard, the foot of which is connected to a boss A on the rear of the frame A by means of a pintle-stud E, on which the standard can turn laterally to accommodate the various adjustments for. right and left miters and other cuts.
D indicates a vertically-adj ustable guide carrier attached to the overhanging arm C of the standard 0, which arm is provided with jaws that embrace and support said carrier,
forming part of Letters Patent No. 414,544, dated November 5, 1889.
Application filed February 21, 1889. fierial No. 300,710. (No model.)
the latter being fitted with suitable bearingsurfaces (Z d. The carrier is retained rigidly in position in connection with the arm 0 by a suitable clamping device G and carries at its lower end the guide-plates F, betweenwhich the saw is guided and supported while in use.
The carrier D is best made in the form of an inverted loop, having on one of its arms the guiding-surfaces d d, that fit within the jaws c to adjust up and down therein, and
adapted to be held at any position of adj ust- I ment by the clamp G, which clamp, in the present instance, consists of a bar or lever pivoted on a fulcrum-pin 72 and with a thumbscrew H fitted therein, as indicated, whereby said lever can be actuated to grip the carrier between it and the opposite jaw, and thus confine the same in place.
The sawguiding plates are formed as shown, one of them being rigidly fixed to the supported arm of the carrier D, while the other is adjustably retained in connection with he free leg of the carrier D, it being confined by lugs f from endwise displacement, and retained vertically by a lip f on the end of the carrier-leg and a swinging clamp I, pivoted on the carrier=arm at 2 and adapted to be forced down upon the top edge of the guide-plate by a thumb-screw K for holding the plate firm. A thumb-screw M is arranged at the back of the plate F for pressing it with greater or less force against the saw-blade, as desired. This device affords facility for using a wide or narrow saw and accommodating thick or thin work. The guides serve as a stop for a back-saw when doing dado work, and may be adjusted at such point as to gage the depth of the dado. A spring may be arranged for pressing the sawguides together at the position of the thumb screw M.
The foot of the standard 0 is disposed be neath the supporting-boss A and the pintlestud E passes through an opening in said boss, and is fitted with ascrew-thread through an opening in the foot of the standard, and a jam-nut c is arranged on its lower end to prevent the stud becoming loosened therein.
A seat-plate L is introduced between the boss A and foot of the standard to form a bearing therefor. A series of screw-studs n are fitted in threaded openings through the foot, the ends of which studs rest against the bearing or seat,plate near its periphery, d'awing the pivot-stud firmly into its seat and closing the bearing, so as to prevent any backlash or looseness in the connecting-joint. The studs 12. also afford facility of adjusting the standard Oin relation to its axis by turning one or more of said studs inward and'others outward, so as to slightly tip the foot relatively to the bearing-plate L and boss A The advantage of this construction will be obvious to any person skilled in the use of miter-boxes, as it affords facility for the 'sq'uaring up, both sidewise and from front to rear,
. ,off the upright guide-supporting arm, to bring the. guides into proper relation as regards the axiahcenter of theadjnsting-arm, and so that thejsaw will stand-at right angles to the bed 1 at-all p'osi tions'of adjustment. This arrange ment ofstuds also permits of adjustment away from square position, so that the saw can be made to cut joints slightly inclined or nndereut, orfor giving drafton pattern-work. Tlief'studsn andiplate L also serve, to take up any backlash in. the center studoccasioned l by wear or otherwise.
The central-part of the frame A is made with a circular flange or segment A fitted with remasses or notches a, that correspond withthe principal positions of adj ustmentat whichthe. saw-guidesare set for use, and'the foot of the adjustable standard; 0 is made with a forwardly-extended arm 0 that carries at its forwardend a 1atch-piece P,.h aving a ,lngqgthat engages with the recessesin said segment A for retaining the, standardO and saw guidesh at their positions of. angular ad j ustmentinrelation to the table and. baclcf plates. The latch is best connected. to the endsfof the. armsO by a long hinging-pin S, which affords lateraladjustment of the latch in relation to the leveror arm 0 This hinge piniis headed or fitted at its ends to prevent the latch from sliding laterally thereon, while allowingthe freeswinging movement of the latch,- andthe pin is confined in the arm 0 by means of, a set-screw V, as indicated. 1 11 5, when it is necessary or desirable to slightly vary the relative adjustment of the latch on the. arm, to bring the overhanging arm C and saw-guides F more or less to the right orleft, it can be done by loosening the set-screw V, slipping the hinge-pin S endwise in the end of the arm,- and then retightening saidset screw V. A spring 'R is attached to the under side of the arm G which acts against the latch-piece P, and thereby forces th'elatch lug'up into the notch a of the segmental flange and retains the parts in en-v gagement, Athumb-screw WV is arranged in the'front' of the latch, which screw turns in against the face of the flange A and serves for '"the' arm 0 standard 0, and saw-guideslF at the adjustment at any particular notch. when desired, and also forretaining any-special adjustment ii'itermediate of the respective notches. The supporting-frame is preferably provided with feet that terminate in pointed or wedge-shaped toes t, that prevent the apparatus from slipping on the bench when used. The two rear toes are directed backward and those of the front feet to the right and left, respectively, as indicated.
I am aware that miter-boxes have heretofore been constructed wherein the adjustment to various angular positions is retained by means of a notched segment and a latch or dogging device. Hence I do not broadly claim such feature; but in all former instances, 'so far as I- am aware, the construction is essentially different from that herein defined and claimed.
WhatI claimas In y invention, to be secured by Letters Batent, is-
1. In anadjustable miter -box, aj standard at the rear of. the bed, havingitsfoot pivot- ;ally. attachedto the'frame, and its upperpart extended forward by an integraloverhanging :arm, in combination with saw-guides supported on the dependingendsofiatwo armed carrier that is. vertically adjustable on said overhanging arm, the work-supportingtable :and back; plates, a stop for retaining the car ;rier and: guides in their. vertical adjustment, and a fastening. for holding said standard w h thesawsuide a he pQSi Qn f ajustable slide or carrier. having the saw,
guides attached thereto, and overhanging supporthaving jaws that embrace said carrier, the c1amping-dog G, and thumb-screw I-I, substantially asand for thepurpose setforth.
