MITE B-B 0X.

Specification o Letters Patent.

Patented Aug. 3, 1909.

Application led March 5, 1909. Serial No. 481,323.

To all 'whom tt may concern:

Be it lm ovrn that l, FRANK liloLnAN, a citizen of the United States, and a resident of est irlonroe, in the parish of Ouachita and State ot Louisiana, have invented certain new and useful Improvements in Miter- Boxes, of Which the following is a specification.

My invention is an improvement in miter boxes, and consists in certain novel constructions and combinations of parts hereinafter described and claimed. A

The object of the invention is to provide a device of the class mentioned, light and compact, and one that vn'll permit the use of an ordinary hand saw by drilling a single hole therein, and With Which the full length of the saiv may be utilized.

A further object is to provide a box, Which iv'll insure a maximum of accuracy both as to angle and line.

Referring to the drawings forming a part hereof, Figure 1 is side view of' the improveinent, Fig.V 2 is a section on the line 2 2 of Fig. 8, Fig, 3 is a section on the line 3 3 of Fig. i, Fig. 4 is a section on the line 4-4 of Fig. 3, Fig. 5 is a detail perspective view of the hook, Fig. 6 is a plan view of the end of the saw support partly in section.

The embodiment shown, comprises a box consisting of a base 1 and a side 2, and supported adjacent to the side is a post or standard 8, cylindrical in form and preferably braced against the bottom by brace 4;. The brace 4; comprises a ring 5 encircling the post, and a foot 6 secured to the base or bottom ot the box, by any suitable means, and a step bearing 7, in Which rests the lower end of the standard is secured to the bottom. rlhe post or standard may be removed from the ring and the step bearing, being merelyr seated therein, and packed in the box, `when not in use. The post or standard is provided with a plurality of longitudinal grooves 8, and a sleeve bearing 9, is rotatably mounted on the post, the sleeve being also movable longitudinally with respect thereto, The sleeve is retained in its angular adjusted position by means of a catch 11, pivoted as at 12, to. a lug or bracket 13 projecting trom the sleeve, the catch being normally pressed into engagement with a groove by a spring lll, and being provided With a head 15 projecting beyond the bracket tor releasin' the rPhe sleeve is provided at one side with a l arm 11, and at one end of the guideway are pro]ect1ng brackets 16, one arranged on each.

side of the ofuidewav and each irovided with an angular slot 17. One end of the arm 11 is provided With an opening through which passes a threaded stem 18 secured to a bar 19, and the free end of the stem is engaged by a Wing nut 20, whereby to clamp the bar against the arm. rhe lower end of the bar is pivoted to the saw 21, by a rivet or bolt 22, and the opposite end of the arm 11 is provided with a split hook 23, having an angular portion 24, for engaging the handle 25 of the saw, a portion of the hook being arranged on each side thereof, the saW blade being received in the split. A hook 26 is pivoted to the top of the post, and is adapted to engage the sleeve 9 or the arm 11, to retain the saw out of the Way when putting in or removing Work. The side 2 ot the box is provided With a Wide slit 27, for permitting the passage of the saw, the slit being near the post, and of a Width su'tlicient to permit the saw to be used at any reasonable angle.

In operation, the work being in position, the catch is lowered, the arm is adjusted to the desired angle, and the catch is released. rlhe arm or sleeve is released from the hook, Which permits the saw to engage the Work. Since the catch remains in engagement With the groove, Whether the saw is up or down, as many cuts may be made as desired, With absolute accuracy, and with the certainty that every cut will be at precisely the same angle. when the Wing nut 20 is screwed tight to clamp the arm and the bar together, there is no possibility of the disengagement of the handle of the sanr from the split hook.

rlhe arm 11 is milled on its side adjacent to the point of attachment ot the bar and the bar is also milled, in order that the parts may be tightly clamped together. The guide- Way 10 is also hushed as at 109 with bronze or other suitable material.

l claim- 1. A device of the class described comprising a base, a standard detachably connected therewith, said standard having a plurality of parallel longitudinal grooves a sleeve provided with a guideway movable longitiuiinally ol the stainlard and rotatable thereon, a spring actuated catch on the sleeve l'or engaging)` a groove, an arm movable in the guideway and provided at one end With a hook lor engaging the handle ol' a saw, a bar guideway 10, in which moves an l provided with .means l'or engaging the blade on, said standard being provided with spaced parallel longitudinal grooves, and the sleeve with a releasable catch for engaging the grooves, the sleeve being provided with a transverse guidevvay, an arm slidable in tne guide-Way and means in connection with tlie arm for rigidly holding a saw in parallelism with tlie arm.

3. A device of the class described, conprising a standard, a sleeve rotatable on the standard and movable longitudinally thereof, means in connection with the standard and tbe sleeve for retaining the sleeve ata predetermined angular adjustment with respect to the standard While permitting it to move longitudinally thereof, the sleevebeing provided Witli a guideway, an arm slidable in the guideway and means in connection with the arm for rigidly holding a saw in parallelism therewith.

4. In a device of the class described, a standard, an arm provided With means for rigidly retaining a saw in parallelism tlierewith, means for rotatably supporting tlie arm on the standard and for permitting it to move longitudinally thereof, and means for retaining the arm at a predetermined angular adjustrnent with respect to the standard, wliile permitting it to move longitudinally thereof.

5. In a device of the class described, a standard, a saw support rotatable on the standard and movable longitudinally thereof, and means for locking the support at a predetermined angular adjustment While permitting it to move longitudinally with respect to tlie standard,

6, In a device of the class described, a standard, a saw support movable longitudinally of the standard and rotatable thereon, means for permitting tbe rotation of tlie support, and means for engaging the support to retain the saw in inoperative position.

7. ,ln a device of the class described, a standard, and a saw support rotatable on tbe standard and movable longitudinally thereof, said standard being provided with spaced parallel longitudinal grooves and a catcli on the support for engaging a predetermined groove.

8. ln a device of tbc class described, an

arm provided at one end with a split hooi; for engaging tbe handle of a saw on opposite sides ci' the blade, a bar forconnecting tlie other end of the arm with the blade of the saw, i ieans for clamping the bar to the arm, and means for supporting the arm.

9. ln a device of tlie class described, a saW support, a post uporL Wliicli the support is rotatable and longitudinally movable, and means for constraining tbe support to move longitudinally of tbe post in parallel lines. FRANK W'. lrfcLEAN. `Witnesses G. W. GOING, A. C. WALTON.
