MITER-BOX.
Application filed March 14, 1911.
Specification of Letters Patent.
Patented An". 13, 1912. Serial No. 614,337.
To all whom it may concern:
Be it known that we, lVlLLIAM A. PREN- TICE and WILLIAM H. PRENTICE, citizens of the United States of America, residing at Worcester, in. the county of W'orcester and State of Massachusetts, have invented certain new and useful Improvements in Miter- Boxes, of whichthe following is a specification.
This invention relates to miter boxes and particularly to a miter box capable of being dismantled or knocked down for the purpose of transportation, the said miter box having novel means for adjustably supporting the saw guide and novel means for supporting the saw guide at different angles of adjustment with relation to the work su ort.
A still further object of this invention is to provide a miter gage pivoted to a base .and having novel means for guiding the said gage and for holding it in different positions of adjustment.
\Vith the foregoing and other objects in View, the invention consists in the detail 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, and in which- Figure 1 illustrates a view in elevation of a miter box embodying the invention; Fig. 2 illustrates a top plan view thereof; Fig. 3 illustrates a view in elevation of the end of the said miter box; Fig. 4 illustrates a plan view of a fragment of a portion of the base showing the miter gage in operative relation thereto; Fig. 5 illustrates a view of the same parts inverted; Fig. 6 illustrates a sectional view on the line E--F of Fig. 4; Fig. 7 illustrates a section on the line AB of Fig. 2 with part of the mechanism omitted; Fig. 8 illustrates a top plan view of the means for adjusting the saw guide support; and Fig. 9 illustrates a sectional view on the line C-D of Fig. 3.
In these drawings 10 denotes a base having a flange 11 standing at right angles thereto, the said flange having at its upper edge a guideway 11. A table 13 is movable longitudinally of the guideway and is providedwith a series of apertures 14 near the edge thereof which are designed to receive the latch bolt 15 which extends through an aperture in the head 16 which head is rotatable on the table. The table has a threaded shank 17, the head of which is slidable in the guideway 11, and said shank extends through the head 13 and is provided with a jam nut 18 designed to clamp the head and table on the guideway.
One edge of the head is provided with a guideway 19 which serves to confine a disk 20 which is mounted on a bolt 21 of the standard 22, the said standard 22 being adjustable along the head and being clamped in different positions of adjustment on the head by means of the bolt which draws the disk against the shoulders 23 which are formed in making the channel in which the disk is movable.
The standard 22 adjustably supports the saw guide which is vertically reciprocable thereon and the saw guide comprises the two jaws 24: and 25, each of which has an ear to receive the pivot 26 by which the jaws 24 and 25 are swingingly mounted with relation to each other. The jaw 24 has screw threaded recesses such as shown at 26, Fig. 1, which are designed to receive the screws 27 by which the jaws are adjusted with relation to each other to provide for perfect uniformity and equality of the space between the respective lateral ends of the jaws 24 and 25. The said screws 27 are arranged equidistantly on the opposite sides of, and
slightly above, the screw in the aperture 26. By loosening the screws 27 and tightening the screw in the aperture 26, the jaws are forced apart: and, by reversing this manipulation of the screws, the jaws are brought into closer proximity, also, by loosening one of the screws 27 and tightening the other screw 27 the width of the spaces between the respective lateral ends of the jaws may be equalized: as will be clearly apparent, there being sufficient looseness in the pivotal connection at 26, and sufficient elasticity in the ears, to allow such slight adjustment as may become necessary. because of wear. inaccurate assembling of the parts etc. The jaw 24 has an enlarged shank as shown at 28 provided with a recess 29 to receive the standard, the clampins: plate 20 being pressed against the standard 22 through the medium of the screws 30 which extend through the clamping plate and are threaded in the enlarged shank 28. By means of the screws 30, there-- fore, the pressure of the clamping plate 29 may be increased or diminished for the purpose of holding the jaws at different positions of adjustment or for releasing said jaws to permit their movement on the said standard.
The lower ends of the aws are quite close together, the space therebetween being equal to the width of a blade of a saw to be used in connection therewith, whereas the said jaws remote from their lower edges are recessed to form a space which will receive the head of a miter saw.
The base 10 is provided with a gage 31 mounted on a pivot 32 in order that the gage may move with relation to the base, the said gage being provided with a stud 33 acting as a guide for the arm 3% which projects from the base. The gage 31 is furthermore provided with a screw 35 having a recess 36 in its edge in which the edge of the arm 34v travels, the said arm 34 being confined between the stud 33 and the screw 35. The arm is mounted on a screw 37 anchored in the base as shown in Fig. 4: and the relation of the arm and stud to the screw will be observed by referring to Fig. 6.
The latch bolt 15 is encircled by a spring 38 seated in the recess 39 formed in the head 16 and the said latch bolt projects into the apertures 14: of the table 13 as well shown in Fig. 7.
The construction of the miter gage will, it is thought, be apparent from the foregoing description and it will be understood that by reason of the rotation of the head 16, the angle of the saw guide with relation to the base may be changed to change the degree of the angle of the cut of the saw with relation to the work supported on the base. It will, furthermore, be apparent from the description and the drawing that the saw guide may be elevated or lowered and that it may be clamped in different positions of adjustment so as to operate upon work of different thicknesses.
We claim- 1. A. miter box comprising a base having a vertical flange, said flange having a horizontal guide-way in its top surface, a horizontally rotatable and reciprocatory membe having a horizontal guide-way, said member being connected with the first said guideway, and a member carrying a saw-guide mounted for horizontal adjustment in the second said guide-way.
2. A miter box comprising a base having a vertical flange, said flange having a horizontal guide-way in its top surface, a reciprocatory and rotatable member having a horizontal guide-way, said member being connected with the first said guideway, and a member carrying a saw-guide mounted for reciprocation in the second said guide-way.
3. The combination in a miter boX, of a base, a vertical flange secured on the base and having a horizontal guide-way extend ing longitudinally thereof, a table recipro cably and non-rotatably connected to the guide-way, a rotatable head journaled on the table, and a saw-guide carried by said head.
In testimony whereof, we aflix our signatures in the presence of two witnesses.
