MITER BOX.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed April 29, 1910. Serial No. 558,382.

To all whom it may concern:

Be it known that I, HERMAN L. LoMoN'r, a citizen of theUnited States, residing at New Haven, in the county of Allen and State of Indiana, have invented new and useful Improvements in Miter-Boxes, of which the following is a specification.

This invention relates to miter boxes and the object thereof is to provide a box of this character whereby ordinary and complicated miter cuts may be made without entailing the use of complicated mechanism.

A still further object of the invention is the provision of amiter box having means whereby the saw guide may be held in position for an undercutmiter and still further means for adjusting the back of the device for any desired cut.

Another object of the invention is the provision of a saw. guidehaving a free swinging end which does not interrupt or restrict the use of different sized material and still further means carried by the free swinging guide for holding the saw in inoperative position and for automatically releasing the same upon an operative movement of the saw. 7 1

Further objects of the invention will appear as the specific description which follows is read in connection with the accompanying drawings which form a part of this specification and in which:

Figure 1 is a front elevation showing the box set for a45 miter cut. Fig. 2 shows a top plan view of the parts in the position shown inFig. 1. Fig. 8 shows a similar view with the parts arranged for a 45 undercut miter. Fig. 4 is a rear elevation showing in full lines'the position of the back for ordinary miter cuts and in dotted lines the position of the back when undercut miters are to be made. Fig. 5 is a central transverse sectional view with the parts shown in position for a square cut. Fig. 6 is a perspective view of one of the arch supporting arms. Fig. 7 is a detail sectional view on the line 77 of Fig.1. Fig. 8 is a detail sectional view on the line 8-S of Fig. 2, and Fig. 9 is a detail perspective view of the shifting lever.

.7 Referring more especially to the drawings, 1 represents the baseof the device, which is semi-circular in form and which comprises a metallic plate 2 and the wood reinforcing therefor, 3. The standard 4 1 which supports the base-is provided with a slot 5 and its separate feet are connected together at their lower ends bybridge pieces 6. Each separate foot of the standard is provided with a pointed projection 7 which engages the bench or other surface upon whichthe box is being used. Pivoted to the back of the plate 2 are a series of vertical slats 8 which are pivotally connected at their upper ends by a bar 9 in a manner similar to a parallel ruler whereby the bar 9 will maintain its parallelism with the base at all times. These slats are secured in sets A andB and are separated by a slot G in the center of the machine through which the saw is adapted to pass in making the necessary cutsQ In practice, these sections of the back are held in their respective positions by friction at their pivotal point and can assume any of the several positions indicated in Fig. 4 whereby different degrees of un dercut miters may be obtained.

lnthe center of the base adjacent its rear side I provide a depending boss 9 which has a central screw 10 passing therethrough, in order that the arch supporting arms 11 may be pivotally connected to the frame for swinging movement. These arms are supported intermediate their length by set screws 12 mounted in lugs 13 projecting rearwardly from the base and which pass through suitable slots 14 formed in an are shaped intermediate portion of the arms. The set screws not only support the arms but hold them in. adjusted position. The outer positions of the arms 11 project vertically or substantially so as at 15 and in their engage the connecting arm 26 of the saw guiding frame 27 The bolt or set screw 25 acts in the same capacity as do the holding members 22 for square and straight miter cuts.

The lower end of the boss is reduced as at '28 to receive-a Wear plate upon which the lever 30 is journaled. The lever extends through the slot 5 between the base 1 and the standards 4: and isprovided with a circular enlargement 31 apertured as at '32 to surround the boss 9 andextendings rear wardly from this bearing portion is an operating arm 33 on the end of which is formed a semi-circular cup 34 slotted at itsbottom as at 35 to receive the connectingbolt 36 carried at the end ofthe main member of the saw frame 27. The lower end of this main member is formed circular as at 37 to engage the cup 34 and oscillate back and forth as shown by dotted lines in Fig.8, to position the saw: for suitable undercuts. A suitable nut 39' is mounted upon the end of the bolt'36 and a friction plate 40 is arranged between the "nut and the cup and fits the latter so thatwear maybe taken up when necessary.

The saw frame comprises the main member 27 which is slotted throughout its length and of substantiallytubular form so as to receive the saw guide 41 in which the saw 42 is adapted to travel: This saw guide is adapted for vertical reciprocation in th'e member 27 as is usual with 'suchstructures and has upon its upper end a limiting collar 42 which prevents the saw from cutt-ingjtoo far into the wooden surfacing -3.'- The upper end of the member 27 has extending outwardly therefrom the connecting arch 26 which has secured to its outer end and depending therefrom, the opposite member 43 of the saw frame which comprises a structure similar in all respects to the member 27 except that it is considerably shorter, its 1loowler end being on a line with the top of the ac mounted therein a saw guide 44 which has a stop collar 45 on its upper end to limit its movement and the notch 46 adjacent its lower end which is adaptedto be engaged by the spring-pressed pawl 47 carried upon the upper endof the member 43. When the I permitting the saw to drop.

Each of the members 22 comprises a hollow bolt 48 which has its head flanged as at 49-to take-over the sides of the arch member-18. The upper end of the bolt is thread- 7 ed to receive a fiange washer 50 whose flanges 51 extend over the upper-edge of the member 18. A suitable lock nut secures the device in-adjusted position and the bolt 52 passes through the bolt 48 and has a pointed archengaging end to engage the arch 26.

The lever 30 is provided at its extremity with a handle'53 and immediately adjacent the handle is a locking pawl 54 which is This member 43 also has slidably,

adapted to engage suitable notches in the faceof' the'plate l so as to hold the saw frame in adjusted positions. The upper fportion of the frame is slotted as at 55 and -56--i11 order to receive set screws which hold stops (not shown) in adjusted position whereby, round work or molding may be se- Tcured upon the base in position to be acted upon by the saw. i It will-be clearly understood how the saw lframe is operated in order to make the ordinary miter cuts or square cuts and it therefore' only'rem'ains necessary'to describe the operation ofthe machine as regards'undercut or complicated miters; WVhen'such a cut is desired, the arms of the arch are shifted sa to the position shown in :Fig. 3, the mem- ';bers ofthe arch hingeof course upon the bolt 24sothat' they occupy'a' position resemblingthe outline of'the letter Vl' When finthis position, the'frame comprisingthe' gmembers'26, 27"and 43*is moved laterally in {its pivoted socket "24"until "the bolt52 is in Yiposition' to engage'thelug'on the top -of the arch 26'. The bolt 52 is then' screwe d into position'and the frame held in this diagonal adjustment. Prior to the-pivotal shifting of the saw' frame, the back'is arranged as shown in'dotted lines in-"Fig; 4and the lever 30' is shifted-so as to-getthe saw frame at the proper angle. When this is accomplished", the set screws 12 are tight'ened and "the box is readyjto be used for an'undercut miter. v Havingjthus described the invention, what is claimed is 1. A miter boxcomprising a work sup port, a horizontally movable lever pivoted thereto, a verticallymovable sa wframe carried by said lever, means to hold thelever in adjusted-- position,-a horizontally swinging frame comprising hinged sections form'- ing an arched body) and movable independentlyof each" other','said fr'amebei-ngfpivote'd to the work support "at-one of its'-hinges,and adjustable means "slida'blymounted upon said frame byjwhich the saw frame may be adjusted indifferent angularpositions, 2. In a miter box, a work support,"a'horizontallymovable lever pivoted to said support, a saw frame comprising a "pair of spaced vertically. extending members, and an arch rigidly connecting said members,

oneofthe said members being shorter than the other, the other member being pivoted to one end ofsaid lever for oscillation in a vertical plane. V

3. A miter box comprising'aw'ork support, a horizontally. movable lever pivoted thereto, asaw frame comprising a pair of spaced members, one of-"saidjmembers' being pivoted-to saidleverf' for movementfin a' vertical plane, an archf'connectingsaid members to support the free member, an'arched frame comprising hinged sections pivotally secured to said work support to swing hori- Zontally, and adjustable means carried by said frame for locking engagement with the arch of the saw frame.
