EDWIN W. WHITMORE, OF WORCESTER, MASSACHUSETTS.

MITER-IBOX.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed September 16, 1907. Serial No. 393,004.

T all whom it may concern:

Be it known that I, EDWIN W. WHITMORE, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Miter-Boxes; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to new and useful improvements in miter boxes and has primarily for its object to provide a novel device of this character which may be readily folded. in order that the same may be made into a compact package for shipping or for carrying.

It is also an object of the invention to provide in combination with a device of this character novel means for engaging and holding the saw in position.

It is also an object of the invention to provide a novel gage for the saw, said gage acting in conjunction with the saw holding mechanism.

It is also an object of the invention to provide a novel arrangement whereby a saw may be adjusted to the various angles required.

It is furthermore, an object of the invention to provide a novel device of this character which will prove an efficient and practically convenient mechanism for the use of wood workers in the sawing of bevels, angles, and other various cuts required in the fitting of lumber and joinery, said mechanism proving at the same time economical and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, in which- Figure 1, is a view in elevation of the invention; Fig. 2, is a view in top plan;

Fig. 3, is a view in rear elevation of the device; Fig. 4, is a view partly in elevation and partly in section of the invention illustrating in dotted lines a saw in position; and Figs. and 6, are views illustrating certain details of the invention.

Referring to the drawings 1, denotes the base having adjacent one end the cut-away portion 2, in which is intended to be fitted a block of wood with which the saw teeth will contact in order to protect said saw teeth from injury. This base late is also provided with a plurality of ibngitudinal open ings 3, which lighten the weight thereof and also prevent the accumulation of waste material more especially of sawdust. This base plate is referably formed of metal and is provided a ong its edges with the depending flanges 4, which form a support therefor. Projecting outwardly from the rear flange approximately centrally thereof and preferably formed therewith is a shelf 5, more particularly shown in Fig. 4.

Held along the rear edge of the base 1, by the hinge 6, is the back plate 7, said back plate being separated as at 8, adjacent the cut-away portion 2. This separation is to permit the reciprocation of the saw, as is, it is thought, obvious to those familiar with this class of invention. The main portion of the back plate 7, is provided with the diagonal or oblique rib 9, for the purpose of reinforcing or strengthening the plate for a purpose which is believed to be clearly apparent. Also to more firmly retain in position a board in contact with the base, should said board slip when coming in contact with the saw in motion, the oblique ribs 9, holding the material being sawed in the desired position; a slight pressure against said ribs 9, tending to impress the edge of said board or partly embed against the oblique ribs 9, which is thought will be fully understood.

Projecting at right angles from the upper edge of the main section of the backing plate 7, adjacent the separation or space 8, is a flange 10, and pivoted to this flange 10, by the stud 11, is a segment 12, )rovided with the teeth 13, and the segmenta slot 14.. The teeth 13, determine the angle of adjustment of the segment and the segment is held in its adjustment by the spring pressed dog 15, which is pivoted to the boss 16, formed on the rear of the backing plate 7, by the pin 17. This dog engages the teeth 13, of the segment and is held in such engagement by the spring 18, which has one end passing through an opening in the flange 10, and its opposite end embedded within the dog. This spring is preferabl bent into an approximately U-shape. While this specific form of spring has been illustrated, it is to be understood that any spring which will perform the desired function with equal facility mayin such adjustment by the clamping nut 11.9 v which is in enga ement with the stud 20, projecting upward-y from the flange :10, .and passing through the segmental slot 14. The

side of the segment above the base 1, is'provided .with the extension 21, which has an edge flush with and in a'linement with "the straight edge 'of the segment 12. These alining edges are provided with the 'T head 22, on which are movable longitudinally the saw holder 23. These saw holders are two :in number, one being positioned on eaoh side 'of the backing plate. i Each-saw holder comprises a longitudinal member 24, lippcd or flanged as at 25, to engage the'T head 122. This .memb'er .24, is :held against movement on the T-head by =the caml26, pivoted to the member 24, and engaging the Tehead.

Carried by themember 24, andiat Irightangles thereto is the guide-way 27, in which slides the saw holder proper :28. i i his saw holder .28, comprises a bifurcated member having its lower end *i ree while the upper portion olfthebifurcati'on isen'la'rgedas at.2 9, to receive the bead of the miter saw. It is thought that it is obvious how the saw is inserted within the holder and :it is to be stated that the bead zthereoi' holds the same again'st displacement. The holders 2-8, are freely movable in their guide-ways to com pe'ns'ateifor the action of the :saw on thema- 'terial'to be out, andare adjustableto theluse of any length of saw within the scope "ofithe movements of the saw rhold'er. I1t1is often necessary to limit "the downward movement of these holders and for such purpose gage rods 30, are employed. fine of these rods isfslidably held "by eaoh of ithe guide w'ays .27., and is provided *on its lower end with ailug or 110093 1, which contacts with the lower end o'f the saw xholder proper 2.8. 'Theggage rod is held in its various adjustments by ;a screw 32, which is provided with @a slot 233, through which the gage .rod passes. flhis screw in turnisengaged'bya nut 34, bearing against the guide-way .27, and thereby so binding the gage and against movement :as 'is more particularly shown in 'Fig.i6. As there is :much strain on the saw holder proper .28 the said saw holder 28, is provided at .28

iisnforcing ribs 35.

withndges of the upper portion oi the bi- .furcationZQ, -extending.longitudinally of the sides of the saw holder, together with the re- This with the enlargement ofthe saw holder affords the required rigidity to the sawholder and ermits the use-of saws without a bead, and a so the use of any saw commonly "used by "wood workers.

"The back plate 7, is provided along its lower edge with a flange 36, which is adapted to contact with the shelf 5-, when the device is in assembled position, and passing through lflange 86, and shelf 5, :are the screws 37, whiehanay engage a frame or :other support.

It is thought that it is clearly understood how the backingplate-and -base:can be folded one with relation to the o'ther when it is desired that the device be moved, shipped or stored. It may be also :further stated that the dog 15, which engages the segment :12, is provided with a 'fingerpiece :38, to zfacili- :tate the movement the'reo f.
