Specification of Letters Patent.
Patented Nov. 22, 1910.
Application filed September 7, 1909. Serial No. 516,583.
To all whom it may concern:
Be it known that I, ALEXANDER ROBBINS,
a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and the State of Michigan, have invented new and useful Improvements in Miter-Boxes.
This invention relates to improvements in miter boxes.
The main objects of this invention are, first, to provide an improved miter box which can be quickly adjusted to enable the cutting of bevel or miter joints of any angle, such as the joints required in rafters and roof boards of roofs, or in forming other joints. Second, to provide an improved miter box adapted to accomplish these results which is very simple in its adjustment, by the aid of which any particular rafter or roof board can be cut or any other board or piece cut, at the desired angle without the aid of a square or the like.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The structure described constitutes one efiective embodiment of my invention.
Other embodiments would be readily devised by those skilled in the art.
The invention is clearly defined and pointed out in the claims.
A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:
Figure 1 is a perspective view of a structure embodying the features of my invention, the work holder 10 being removed. Fig. 2 is a detail perspective of the structure shown in Fig. 1, with the work holders 10 in position, the saw and portions of the saw guide being broken away. Fig. 3 is a detail front elevation with the work holders 1O removed, and also the saw guide, and the parts below the main body base plate. Fig. 4 is an enlarged detail of the parts shown in Fig. 3, with one of the work holders 10 in position. Fig. 5 is a detail end elevation looking from the right of Fig. 4. Fig. 6 is an enlarged detail vertical section taken on a line corresponding to line 66 of Fig. 4. Fig. 7 is a detail section taken on a line corresponding to line 7--7 of Fig, 4, showing the means of attaching my improved work support to the main body.
In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views arev taken looking in the direction of the little arrows at the ends of the section lines.
In the accompanying drawing I have shown my improvements embodied in a miter box of a well known type. My improvements being adapted to be added or attached to such a structure.
Referring to the drawings, 1 represents the body of the miter box, consisting of a base and a back, the back being arranged at right angles to the base and being provided with a central slit or saw opening.
A saw guide mounted on a vertical pivot is provided, but as the details of these parts form no part of my invention, and are well understood, I do not illustrate the same herein.
I provide a pair of work supporters 2, each comprising a base plate and a back plate, arranged at right angles to each other, the back plate being secured to the main back of the miter box as by means of bolts 3. The back plate is provided with series of holes, each one preferably having a plurality of series as 4, 5 and 6, the series 4 and 6 being vertically arranged and parallel, while the series 5 are horizontally arranged and preferably extend outwardly from the upper end of the series 4, as clearly appears in the drawings.
The work supports 2 are arranged on opposite sides of the central saw slit in the body back, and are preferably spaced so that their inner ends 8 form work rests for a piece of work arranged on the supports, as is shown in Fig. 1, the pin 7 being arranged through the gage holes to co-act with the rests 8 for supporting the work, as will be obvious from an inspection of Fig. 1. I preferably provide in this connection, work holders 10 which are trough-like in shape and right angled in cross section, and provided with bearing members 11 at the angles. These bearing members are adapted to be engaged with the bearings 9 on the work support base plate, so that the work holders 10 can be rocked or tilted on their bearings having gage holes 13 therein adapted to receive the supporting pins 14, the pins 15 being arranged through the gage holes in 'the back plate to assist in supporting the holders. These pins 15 are preferably threaded, as clearly appears in Figs. 51and 6. With the parts thus arranged, substantially any angle can be cut that is desired, by the proper adjustment of the work supports and the saw guide.
The gage holes in the back plate and in the support 12 are preferably provided with a scale so that the workmen can readily adjust the device to the work required.
I have illustrated and described my improvements in the form in which I have embodied them, as I find that form to be satisfactory. I am, however, aware that considerable modification in structural details is possible without departing from my invention, and I desire to be understood as claiming the same specifically in the form illustrated, as well as broadly within the scope of the appended claims.
Having thus described by invention, what I claim as new and desire to secure by Let ters Patent is:
