Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed March 20,1917. Serial No. 156,119.

To all LU/tom t may concern.'

Be it known that I, ELMER C. EAGLnsoN, a citizen of the United States, residing at Dayton, in the county of Columbia and State of lllashington, have invented certain new and useful Improvements in Miter-Boxes, of which the following is a specification.

This invention relates to an improved miter box and has as its primary object to provide a device of this character adjustable for making miter cuts at various horizontal angles.

The invention has as a further object to provide a miter box adjustable for making mitcr cuts at various vertical angles.

A still further object of the invention is to provide a device of the above described character wherein the miter cuts may be made at various horizontal and vertical angles simultaneously to thus impart a bevel to the miters.

A further object of the invention is to provide an arrangement'wherein the posts of the saw guide may be adjusted upon 'the supporting member therefor for tilting the posts with respect to the vertical and thus inclining the saw for making miter cuts at various vertical angles and to further provide an improved mounting for the said posts. l

And the invention has as a still further object to provide an arrangement wherein the posts of the saw guide will be frictionally held at adjustment and wherein means will also be provided for rigidly locking the post at adjustment.

Gther and incidental objects will appear as the description proceeds and in the drawings wherein 1 have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

Fig. 11 is detail showing the catch.

In carrying out the invention, my iirproved miter box is formed with a base 10 supported by suitable legs 11. Formed on the forward side of the base substantially midway of the ends thereof, is a segmental plate 12 provided, upon its outer edge, as particularly shown in Fig. 1, with a suitable scale having graduations indicating the degrees of a circle. Upon its inner side, the plate 12 is undercut to provide a flange 1B and formed in the lower edge of the plate is an arcuate series of notches one of which is shown at 14. Opposite the plate 12, the base 10 is formed with a bearing 15 and pivotally mounted upon this bearing to extend horizontally beneath the base is an arm 16 of a saw guide, the said arm projecting at opposite sides of the base. This arm, at its rear extremity, is formed with a socket 17 and at its forward extremity, is provided with spaced sockets 18 and 19 respectively.

Vpurpose of these sockets will presently ap- 'Y cate upon the arm 16 and is operable by '19 respectively.

cams 22 arranged at opposite sides of the saidlarm and engaged by a yoke 23 pivoted, at its inner extremity, upon the arm immediately in the rear of the pin 21. rl`he arms of the yoke 23 are received by guide pins 24 and interposed between the said yoke arms and the arm 16 to surround the said guide pins are springs 25 normally urging the free extremity of the yoke .downwardly and acting upon the cams 22 toyieldably force the catch pin 21 upwardly for engagement within one of the notches 14. Accordingly, by

properly manipulating the yoke 23, the arm 16 of the saw guide may be adjusted to various horizontal angles which may be read upon the scale at the front edge of the plate 12. Mounted upon the base 10 to extend longitudinally thereof, isthe bed 26 of a box proper and associated with this bed to extend at substantially right angles thereto is the fence 27 of the box. Extending rearwardly from. the'base in a plane substantially parallel with the bed 26 are bracketsy 28 and adjustably Y connected with these brackets by suitable set screws as particu-l larly shown in Fig. 2, are work clamps. 29 shiftable transversely of the bed. l All of this structure,'as thus described, with the exception of theV fence 27 may be of any suitable design, it onlyv being necessary for the purposes of the present invention that the arm 16 of the saw guide be pivoted for adjustment'in a horizontal plane with respect to the bed 26 of the box proper and provided with sockets similar to the sockets 17, 18 and The fence 27 of the box proper is, as par ticularly shown in Fig. 2, provided int-ermediate its ends with a substantially V- shaped notch 30 andy fitting in the said notch are swingingly mounted fence sections 31 confronting, at their inner ends, to Ydefine a slot 32 adapted Vto receive the saw when making ordinary miter cuts at various horizontal angles. Connected with the fence sections 31 are supporting arms 33 therefor which, at their outer extremities, are mounted upon pivot bolts 34 fitted through A the fence and provided with suitable wing nuts to clamp against the arms. The fence sections may thus be adjusted to the position shown in Fig. 2 to be held at adjustment by the said bolts or may be swung to the position shown in Fig. 1, projecting beyond opposite ends of the fence with the bolts 34 operable for holding the said fence sections at adjustment. ln this latter position of the ,fenceY sections, unobstructed movement of the saw with respect to the verticalwithin the notch 30 will be permitted.V Con-V the fence sections 31 are spaced fingers36 arranged to confront the innerside face of the fence. These fingers are thus adapted to hold the fence sections 31 against lateral displacement within the notch 30.

Mounted upon the arm 16 of the saw guide are spaced socket members for the f posts of the saw guide. These socket members each include a body 37 provided with spaced upstanding side walls 38 and 39 respectively with the body cut away between thesaid walls to define an arcuate socket 40. Depending from the body is a cylindrical shank 41 andas willnow be observed upon reference to Fig. 4, the socket member is split medially to define coacting mating sections 42 and 43 respectively, the wall 38 being carried by the section 42 while the wall 39 is carried by the section 43. Also,'each of the sections carry a portion ofthe shank 41. Formed in the bottom of the socket 40 upon the section 42A of the socket member is, as shown in detail in Fig. 6, an arcuate shoulder 44 projecting inwardly from the wall 38 of the said section. At one end, this shoulder is formed with a suitable notch while, at the opposite end of the shoulder, the wall 38 is soV formed lwith an enlargement providing a Y upon the said shoulder is an arcuate resilientA friction band 47 provided, at one extremity, with a hook 48 engaged within said notch and at its opposite extremity with a threaded shank orY terminal 49 extending loosely through the opening 46 and fitted with a nut 50 engaged with the seat 45. s will be clear, the nut 50 may be adjusted-upon the Ishank 49 for shortening the radius of the band. Formedin the upper margin of the wall 38 is an arcuate notch 51 and projecting laterally from the said wall and arranged concentric to the notch 51 as well as concentric to the shoulder 44 and band 47 is an arcuate bearing shoulder 52. Projecting laterally from the shoulder 44, at its extremities, are lugs 53. Y j

The section 43 of the socket member is, as shown in detail in Fig. 7, formed with an iio arcuate Ybearing shoulder 54V projecting latfrom the shoulder, at its extremities, vare lugs 56. Formed in the upper margin of the wall 33 is an arcuate notch 57 similar t0 the .notch 51 of the section 42 and of equal radius therewith. As will now be observed upon reference to Figs. 3 and 4 of the drawings, the sections 42 and 43 of the socket members respectively are arranged to seat flat against each other with the lugs 53 and 56 of the said members abutt-ing for supporting the walls 38 and 39 of the said socket members in spaced relation. The Shanks 41 of the said socket members are arranged to removably fit within the sockets 17, 18 and 19 of the arm 16 of the saw guide and for ordinary purposes, one of the said socket members is, as best shown in Fig. 3, fitted within the socket 17 while the other of the said members is tted within the socket 1S. Threaded into the shanks 41 of the said socket members are expander bolts 5S Vdetach-ably connecting the said socket members with the arm of the saw guide.

Arranged to coperate with the socket members are substantially cylindrical hubs 59 for the posts of the saw guide. The hubs 59 are each formed with a radial saw receiving slot 60 intersecting the axis of the hub and at opposite sides of which are mounted upstanding parallel rods 61 forming one of the posts of the saw guide, these rods being screw threaded into the hub or secured thereto in any'other suitable manner. Upon one side, the hub is cut away to provide a substantially circular channel 62 concentric to the axis of the hub and of equal radius with the bearing shoulders 52 respectively ofthe socket members. Projecting laterally from the hub, at the inner end of the slot 60, is an arcuate bearing shoulder 63 also concentric with the axis of the hub.

The hubs 59 are rotatably received-betweenV the walls 38 and 39 of the sockets 40 to rest upon the shoulders 54 of the sections 43 of the socket members with the shoulders 52 of the sections 42 of the said members fitting within the channels 62 of the ,hubs so that the bearing flanges 63 thus seat within the said shoulders. The hubs 59 may thus be rocked upon the socket members with the friction bands 47 confronting the outer faces of the said hubs.v Formed in the outer faces of the hubs 59 are a plurality of sockets 64 corresponding to the gra'duations of scales 65 upon the sections 43 of the socket members and arranged to coperate with the said scales are pointers 66 carried by the hubs.

As illustrated in Figs. 1 and 3 of the drawings, the posts of the saw guide are supported by the hubs 59 in substantially parallel relation and slidably vmounted upon the rods 61 of the said posts are sleeves 67 which may be of any suitable character and are adapted to receive a saw, as conventionally illustrated at 68. Connected with the sleeves 67 are spring pressed catches 69 for automatically locking the sleeves to support the saw in elevated position upon the posts of the saw guide. These catches 69 may also, be of any conventional design.

Mounted upon the upper extremities of the posts of the saw guide, is a connecting bar 70 therefor, shown in detail in Fig. 9 of the drawings. This bar is'provided with a plurality of enlargements 71, 72 and 73 respectively, spaced apart to correspond to the spacing of the sockets 17, 18 and 19. Formed in each of the said enlargements are spaced openings 74. The upper ends of the rods 61 of each of the posts of the saw guide are, as shown in detail in Fig. 10, cut away to provide spaced lugs 75 adapted to engage within the openings 74 of the said enlargements respectively and in mounting the bar in position, the said bar is preferably arranged with the enlargement 71 at the front post of the saw guide so that the enlargement 72 will be disposed at the rear post of the said guide. Connecting the bar 70 with the said posts are clamps each including a yoke 76 extending between the rods of one of the saw guide posts and removably fitted through the yoke to extend through the bar are screws 77 threaded into the rods. Mounted upon the yoke is a clamp screw 78 adjustable to engage the bar between the post rods. The clamp screws 78 may, therefore, be operated to tightly bind the bar 70 in engagement with the lugs 75 of the rods of the saw guide posts with the bar thus supporting the rods of each post against movement relative to each other as well as rigidly supporting the posts spaced apart.

As will now be seen, the arm 16 may be swung upon the base 10 to adjust the saw for making miter cuts at various horizontal angles. For making a miter cut at a vertical angle, the sections 31 of the fence 37 of the box proper are first displaced when the saw is tilted by rocking the hubs 59 of the posts of the saw guide within the socket members therefor to accordingly incline the said posts. Upon consulting either of the scales 65 upon the socket members, the vertical angle of adjustment of the saw guide posts may be easily determined by means of the pointers 66 when, by manipulating the set screws 55 to engage within corresponding ones of the sockets 64, the posts of the saw guide may be rigidly locked at adjustment. However, it may not always be desirabie to thus rigidly lock thel posts of theV saw guide and the. friction bands 47 are accordingly provided. By adjusting the nuts 50 of the said bands, these bands may 'be tensioned against the hubs 59 of the saw guide posts to frictionally engage therewith and accordingly tension the hubs in their rocking movement within the socket members. The frictional action of these bands upon the hubs 59 will, therefore, under ordinary conditions, suffice to hold the posts of the saw guide at adjustment when y swung intoV angular relation with respect I saw guide may be adjusted to tilt the saw for making miter cuts at various vertical angles and in this connection, it is to be Vobserved that the slots 60- in the hubs 59 of the saw Lguide posts are arranged to register with the notches 51 and -57 of the sockets for the hubs so that the saw may, as illustrated in Fig. l, be received within the said slots and notches to rest against the bed 26 of the box proper. Furthermore, particular attention is directed to the fact that owing to the mounting of the hubs 59 and the arrangement of the saw between the rods 6l of the posts of the saw guide, the saw will always be supported to extend radially I of the axes of the hubs and will thus be held to accurately cut a miter at the particular angle of adjustment of the said posts.

In view of the preceding description, it will now be understood that the arm 16 of the saw guide may first be adjusted to any desired horizontal angle and the posts of the saw guide then adjusted to any desired angle with respect to the Vertical so that the saw may then be operated for making a miter cut at the said horizontal and vertical angles simultaneously to thus impart a bevel to the miter.

It will therefore be seen that I provide a guide may be engaged within the socket 19 of the arm 16 when the enlarged portion 73 of the connecting bar 70 will then be disposed to receive the rods of the rear post of the saw guide. This arrangement may sometimes be found necessary in cutting wide timbers and it is to be observed that the rod 7 0 will, at all times, rigidly support the posts of the saw guide for simultaneous ad`ustment;
