MITER-BOX.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application led October 12, 1916. Serial No. 125,272.

both a wooden and a metal miter' box, vbut avoiding certain disadvantages of each while at the same time providing further advantages not found in either of the ordinary types of miter boxes.

In accordance with the present invention y the miter box comprises a body or base member which maybe made of metal for compactness and strength, and on opposite sides the body member is provided with rows of posts and wooden pins constituting guides for the saw and permitting the use of either an ordinary hand saw or a back saw. The pins and posts have cofacting parts permitting the firm lodging of the pins in the posts in diderentadjusted positions or the ready loosening of the pins from the posts for readjustment orremoval.

The invention provides for certain fixed angles of cut comprising the more generally used angles and their opposites, except that the 900 cut has no opposite, and provides adjustable means whereby other angles of cut than the fixed ones may be made, the 'opposite cuts to the adjustable angles being automatically provided for.

The invention has all the advantages of an all metal miter box with all the adjustments there provided, with the further advantage that With any angle of cut provided, except 900, the opposite angle iS present as in the ordinarywooden miter box, but with a far greater range of angles than is provided in the ordinary wooden miter box. j

The invention will be bestr understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that -while .the drawings show a practical form of the invention, the latter is not con-fined to any strict conformity with the showing ofthe drawings, but may be changed and modied sov long as such changes and modications come within the scope ofthe appended claims.

Fig. 1l is a side elevation of the ystructure of Fig. 10 with the pins in place.

Fig. 12 is an end elevation of the structure shown in Fig. 11, the View being taken from'the righthand end of the showing of Fig. 11. l

Referring first to Fig. l and associated figures there is shown a base member 1 provided with longitudinal side channel portions 2, 3, respectively, extending the length of the base member, which latter is usually longer than wide. This form of the invention permits the production Vof the base member of sheet metal, thus providing a light, and` at the same time a strong member particularly resistant to breakage. The top line 8-8 of 4of the base member may be in the form of a plate ldesigned to support a wooden strip or ioorfpiece 5 upon which the work to be sawed is placed, and which also provides a means into which the saw teeth may enter slightly without harm, so as to completel traverse the work. v

In order to brace the channel members they are connected at each end at the bottom by strips 6a. Y

At various points along both channel portions the latter are pierced by alined pasn sages 6, 7, respectively, each pair oi passages constituting in effect a socket. Engaged in each socket is oneend ot a tubular post 8 slit or slotted longitudinally on diametrically opposite sides, the slots being shown at 9. The tubular posts stand upright in the working position of the miter box, and the' slots 9 enter the top of each tubular post andA extend to a point below the top surface of the board 5 and may extend to or nearly to the top member 4: of the basic member 1. The posts 8 are secured in any suitablemanner in the sockets receiving them, so that when once set the posts 8 are fixed in position with respect to the base 1. Each post Y 8 on one side ot the miter box has its slots 9 alined with similar slots in another post on the other side of the miter box, wherefore the posts are in etfect arranged in pairs on the opposite sides of the miter box.y For instance, in the structure of Fig. 1 there are ve posts 8 on each side ot one end portion of the miter box, these pests occupying about halt the length ot" the miter box as illustrated in Fig. l. The end posts 8y on one siderot the miter box match the end posts 8 on the other side of the niiter box, except that each end post on one side has its matching end post at the oppositeend of the series of'posts on the opposite side and the parts are so arranged and disposed that with the slots 9 in ,aline/ment the plane ofV such alinement is arranged" at fortyftive degrees to the longitudinal center line of the miter kbox. The middle posts of the series ot' tive on each side ot the niiter box have their slots 9 in `alinement in a plane perpendicular to the longitudinal center line of the miter box, and, therefore', such plane is at right angles to the longitudinal center line ot the miter box. The alined slots of the remaining posts on opposite sides ofthe center post and between the center post and the end posts havev their matching slots in planes at sixtyseven and one-half degrees o the longitudinal center line of the miter ox. Y i

Adapted to each post is' a pin 10, such pin being conveniently 'made 'of hard wood. The pin is ot such diameter as to lit snugly in av respective post 8 and may enter the top of the post and extend close to the bottom thereof. Each pin .10 is provided at what constitutes its upper1 end in the working position ot the parts with a head 11 of greater diameter than the diameter of the body of thepin, and where the head and pin join there is eformed a substantially annular groove 12 suitably tapered to have the upper end 13 of the post tirmly engaged therein, such upper end being correspondingly ta pered. Extending longitudinally and diametrically of the pinflO is a slot 11i traversing the head 11 and entering the pin 10 to a depth suilicient to bring it at or slightly below the top face oit the board 5 when the pin is properly seated in the corresponding post.

lVhen the pins 10 areplaced in the posts 8 the slots 11i are brought into substantial alinement with the slots 9 and the slot 14 of any particular pin 10 is made to aline with the slot 1i in the companion pin on the other side of the miter box. TWhen this is accomplished a blow delivered upon the head 11 of the pin. serves to wedge it tightly on the beveled or wedge-shaped upper end 13 of thepost containing the pin, so that the pin becomes effectively immovable, so tar as its relation to the post is concerned. 1i it be desired at any time to remove a pin, a blow on the under side of the head 11 is sutlicient to loosen the pin and permit its withdrawal, for while the pin lits snugly in a respective post, such iit is not so close as to prevent the ready removal of the pin when it is needful to substitute another pin there'-` for.

TWhen the pins have been properly set in they posts S'the miter box is provided with saw guides formed by the pins for the production ot certain cuts, usually those eus tomarily provided for in wooden miter boxes. The aw guides so tar as the parts engaging the saw are concerned are u'oal'and, therefore, an ordinary hand saw ma y be used in the miter box although ot course a back saw of propensize may be employed. In this .'es'prct the ruiter box is similar to the o` dinary uooden miter bor and has the advantage possessed by the wooden miter box, in that for each'angular cut, other than ninety degrees, the opposite cut may be made without any adjustment of aarts such as are required by the iron miter box. With the ordinary wooden mit-er box the repeated use of the saw, its insertion and removal, results in widening the slots, so that after a while the miter box has lost its reliability and a, new miter box must be obtained. .ln the miter box of this invention when the wooden pegs become worn they are readily replaced by new pegs and may be readily adjusted into proper relation by any one without the exercise of any special care. By inserting the 'pegs Aloosely inthe columns in Awhich they tit snugly enough, for adjusting purposes, the pegs may beproperly alned by inserting alsaw, whereupon on the removalof the saw the pegs may be driven tightly into place by blows delivered on the heads 11. The tubular posts 8 provide means for insuring the proper positioning Aof the pegs or pins 10` .when alined by an inserted saw.

In order to provide a backing for the work, a strip- 15 is applied to the top of the channel 2, being held thereto by bolts 16, or in any other appropriate manner, and this strip has a rising flange along one edge, which flange may reach close to the under surface of the heads 1 1 on the particular side of the miter box. vThe flange is in fact a multiple flange represented by numerous sections 17 spaced apart to permit the passage of the saw to and through the slots in the respective posts 8 and pins 10. n Y

Erected on the channel 2 are other posts 8a which may be in all respects similar to the posts 8 as to their spacing and being provided with slots 9a considerably wider than the slot 9 of the posts 8, this permitting a turning of the pins 10 therein to adjust theml for different angles than can be made with the pins 10 in the posts 8.

The channel 3 at that end opposite thev posts 8L is provided with a longitudinal slot 18, and this portion of the channel supports blocks or carriers 19 each having a central elongated rib or spline 20 on what constitutes its under face to engage in the slot 18 and guide the block along the upper face of the channel`3. To lio-ld the blocks from lifting from the channel each block has a threaded pin 21 extending into the channel 3 and there receiving a nut 22 confining a link 23 against a washer` 24 surro-unding the pin 21 and spacing the link 23 Vfromvthe rib 20 and the under face of the top memberof the channel 3. The parts are so adjusted that the blocks 19 may be moved toward or from each other along the top of the channel 3 to equal extents. To accomplish this the links 23 are brought together at the ends remote from the blocks 19 and are there joined by a bolt 25 extending through a slot 26 in a.

bar 27 arranged transversely of the miter box from thechannel 2 to the channel 3. A nut 28 on the bolt 25 serves to confine the connected ends of the links 23 to the bar or guide strip 27. To lock the parts in ad.- justed `positions one of the pins 21! instead o1 being provided with a nut 22 carries a tail nut 29 provided with a manipulating handle or tail 30 projecting through a slot 31 in one upright wall of the channel 3, so

thatthe parts may be conveniently clampedv in adjusted positions by a manipulation of' the tail nut.

- Rising from each block 19 is a. tubular post 84J having a circumferentially.extended upright slot 9b. The posts 8P carry pins 10 like the other posts.

By theuse of the' posts 8a. which are'eduiF distantly disposed along the channel 2 andv pins to all the angles usually provided with 'an iron miter box and angles which are not provided forin theV other end of the miter box. With the four equi-distantly disposed` posts 8a and the two adjustable posts 8D and with the rotatably adjustableslotted pins 1() any angles from forty-five to ninety degrees yare obtainable, and when any angleiis set the opposite angle is also set automatically,

whereby the opposite angles may be cut to fit withoutV any adjustment whatever of the miter box to obtainy the oppositeV angle.

- With the customary iron miter box, ifacut is made at one angle the miterbox must be reset to obtain the opposite cut. This avoids any liability of a faulty resetting of thek miter box to obtain the opposite cut after' the first cut is obtained.

vThe board 5 may be secured in'place byV screws 32, or in any othersuitable manner.

In the structure of Fig. 10 and associated figures there is a base member 33 formed by casting, and tubular posts 34` and 34a.v corresponding to the posts 8 and 8:L of the structure of Fig. 1 maybe cast separately from the base 33 land secured thereto by screws 33a. VFurthermore, the posts 34 and 34a are joined together by webs 35 which may be cast in'one piece with the posts and with the base 33. A backing plate 36 correspondingto the backing plate 17 of Fig. 1 is also cast with the base 33 and may where adjacent to corresponding .posts 34 and 34 be integral therewith. Of course, the backing plate 36 is made in a suitable number of sections for the same reason that the web 17 is made multi-sectional.

` The base 33 where covered by the board 5 is formed with numerous openings 37 to re-' connecting the blocks 19 as before, the base 33 being provided with a longitudinal slotl 18a corresponding to the slot y1.8 of Fig. 1. The other parts being of like construction need no particular description. The opera,- tion of the structure of Fig. 10 and associated figures is like that of Fig. 1 and associated figures and requires no special description.
