INVENTOR. flA/Fd EYA viva/{5811mm Patented Mar. 31, 1953 UNITED STATES PATENT OFFICE PORTABLE MITER BOXFOR rowan- DRIVEN HANDSAWS.

HarleyA. Neuenschwander, Hutchinson, Kans.

Application July 6, 1951,Serlal No.235l470 1 Claim. (01. l43--6) This invention relates to a miter'box and has for its primary'object to guide a power driven hand saw along a selected rectilinear-path.

Another object is to facilitate the accurate cutting of material at the job and hence to facilitate the rapid erection of structures such as buildings.

A further object is 'to enable the device to be readily transported'and set up for use without requiring theuse of a cumbersome and heavy bench'or the like. In fact nothing is required in'the way'of a bench or table other than a plank of a width suificient to support the material to be cut when the latter lies fiat.

The above and other objects may be attained by employing this invention which embodies among its features a laterally extensible subframe carrying on opposite sides adjacent opposite ends hangers which are adapted to be secured to a plank or the like to suspend the subframe in spaced relation therebelow, an elongated substantially U,-shaped yoke pivotally con- ;nected substantially midway between opposite ends to the sub-frame intermediate .the ends thereof, spaced parallel guide bars carried by the U-shaped yoke in vertically spaced relation thereto, said guide bars extending across the upper side of the plank or the like and meansto hold the yoke and guide bars against rotation about the pivot.

Other features include a quadrant carried by the sub-frame with its curved edge concentric about the pivotal connection of the yoke with the sub-frame, indicia carried by the quadrant adjacent the curved edge thereof, a pointer on the yoke and extending toward the curved edge of the quadrant for cooperation with the indicia in determining the angle of the yoke relative to the plank.

Still other features include extensions on the hangers projecting upwardly above opposite sides of the plank to form guides for the work and means carried by the U-shaped yoke and engaging the quadrant to hold the yoke and guides carried thereby in definite angular relation to work resting on the plank between the guides.

In the drawings:

Figure 1 is a perspective view of a miter box embodying the features of this invention;

Figure 2 is a top plan view of the device of Figure 1;

Figure 3 is a bottom plan of the device;

Figure 4 is a front view of the device;

Figure 5 is a longitudinal sectional view of the device;

Figure 61s atransverse sectionalv'iew through the device;

Figure 7 is'a fragmentary horizontal sectional view taken substantially on the line l-1 of Figure 6;

Figure 8 is a fragmentary sectional 'viewt'aken substantially on the line '8--8 of Figure 6, and

Figure 9 "(sheet 2) is an enlarged fragmentary side view of the quadrant and pointer-showin the clamping means thereof in-detail.

Referring to the drawings in detail a supporting frame designated generally Ill comprises spaced parallel side bars 12 and 14 which are provided adjacent opposite ends with vertically extending hanger arms 16 having formed intermediate their ends -open'ings for the reception of nails 18 by which the frame I8 is connected "to a'convenient table forming body such as a plank P. The portions of the arms 16 above "the nail receiving openings extend upwardly beyond the top surface of the plank Pto form guides 2ll'for work supported on said plank. Fixed to the side bar l2 substantially midway between opposite ends thereof and extending perpendicularly thereto across the top of the side bar is a bearing support 22 which is provided intermediate its ends with a bearing plate 24. The support 22 and bearing plate 24 are provided with aligning openings for the reception of a pivot pin 26, the purpose of which will hereinafter appear. Also fixed to the side bar l2 and projecting outwardly therefrom opposite the support 22 is a substantially semi-circular quadrant 28 the curved edge of which lies in concentric spaced relation to the pivot pin 26. Carried on the upper face of the quadrant 28 adjacent the curved edge thereof is a curved row of indicia 30 indicating various angular degrees relative to the axis of the pivot pin 26.

Mounted on the pivot pin 26 for rotation on the bearing 24 about the axis of said pin 26 is a carriage designated generally 32. This 08,1! riage comprises a supporting bar 34 having an opening 36 extending therethrough intermediate its ends and carrying adjacent opposite ends upstanding arms 38 and 40. The arm 40 is disposed above the quadrant 28 and fixed to said arm and extending downwardly therefrom adjacent the curved edge of the quadrant is a rod 42, the lower end of which is threaded to accommodate a wing nut 44. A pointer 46 is carried by the bar 34 and rides over the top of the quadrant 28 adjacent its curved edge for cooperation with the indicia 30 to indicate the position of the carriage 32 relative to the supporting frame In. Mounted for sliding movement on the rod 42 between the under side of the quadrant 28 and the wing nut 44 is a clamp collar 48 which when the wing nut 44 is advanced on the rod 42 toward the carriage 32 engages the under side of the quadrant 28 and clamps it firmly against the under side of the pointer.

Fixed to the upstanding arms 38 and 40 adjacent the upper ends thereof are cross arms 50 and 52 respectively. These cross arms lie perpendicular to the supporting bar 34 in longitudinally spaced relation thereto and above the table or plank P, and carried by and extending between the cross arms 50 and 52 on one side of the supporting bar 34 is a guide rail 54. Formed in each cross arm 50 and 52'adl'acent the end thereof remote from the guide rail 54 is a longitudinal row of longitudinally spaced openings 56. A second guide rail 55 extends between the crossarms 50 and is adjustably held in spaced parallel relation to the rail 54 by pins 60 carried by said guide rail 58 adjacent opposite ends thereof. It will be evident that by moving the rail 58 toward or away from the rail 54 that saw frames of diiiering widths may be used with the device.

; In use the supporting frame iii is secured to a plank by fastening the hangers IE to opposide side edges thereof. With the device thus mounted the plank P will serve as a table so that .work may be supported thereon and moved longitudinally between the guides 20. A power driven hand saw S (Figure 4) is then mounted on the guide rails 54 and-f58 substantially as shown so .that its blade B just barely misses contact with the plank P. By loosening the wing nut 44, the carriage may be rotated about the pivot pin 26 to the desired angle and upon tightening the wing nut, the carriage will be locked in the desired angular position. Upon advancing work alon the plank P beneath the guide bars 54 and .5Band then moving the saw S along said guide bars, it will be evident that the work will be out along the path of movement of the blade B and at the angle indicated by the pointer 46 and the .indicia30.

What is claimed is:

A device of the character. described comprising a supporting frame including a pair of spaced parallel longitudinally extending side bars, a hanger arm extending vertically upwardly from each end portion of each side bar, said hanger arms each having openings spaced from the upper end thereof whereby the same may be attached to a horizontally extending plank, a bearing support affixed centrally to one of said side bars and extending horizontally and laterally over the other of said side bars, a bearing plate mounted on said support, a U-shaped supporting bar having an elongated bight portion, a pin centrally extending through said bearing support, said plate and said bight portion, a quadrant afiixed to and extending horizontally outwardly from-one of said side bars and having its peripheral edge concentric with said pin, a cross arm afiixed centrallyt'o each of the legs of the supporting bar, a fixed rail interconnecting one pair of .opposed ends of said cross bars, a second rail interconnecting the other pair of opposed ends of said cross bars in laterally adjustable manner, a power-driven hand saw slidably mounted upon said rails and having a blade extending in a plane parallel to said rails, a pointer carried by that leg of said U-shaped member adjacent said quadrant, a rod extending downwardly from said lastmentioned leg adjacent the peripheral edge of said quadrant, a clamp collar slidable upon said rod beneath said quadrant, and a wing nut on said rod adapted to force said collar into locking engagement with the underside of said quadrant.
