- the lever is held to the plate 13-. A latch 19 is fulcrumed at its'rear end on the lever 15 and extends forwardly beneath and nearly to the front end of said lever. Screws or posts 20, 21 are seated in the lever 15 and extend downward on opposite sidesof the latch 19. A bar washer 22 is mounted loosely on the screws 20, 21 and crosses beneath the latch 19. Expansive coil springs 23', 24 are mounted on the screws 20, 21 between and impinging the heads of the screws and the bar washer 22. It is the function of the springs 23, 24 to hold the latch 19 yieldingly against the bottom of the lever 15. A in 25 is mounted pivotall in the latch 19 and extends vertically throug an aperture in the lever 15 and through one or another of holes 26 in the plate 13. It is the function of the in 25 to lock the lever in any desired angle relative to the plate 13. A headed pin 27 is fixed in the outer end ortion of the latch 19 and extends loosely t on h an aperture in the outer end portion oft e lever 15. It is the function of the headed pin 27 to receive thumb pressure of the operator and depress the latch 19 sufficiently to withdraw the pin 25 from engagement with the plate 13 and permit an angular adjustment of the lever 15 relative to said plate. That portion of the lever 15 at the rear of the bolt '16 is formed as a journal and a sleeve 28 is mounted loosely thereon. Holes 29 are formed in the sleeve 28 and its journal (Fi 2 and 6) and a key 30 is mounted removab y, replaceabl and interchangeably in said holes to determine circumferential adjustment of the sleeve on the journal. Guides 31, 32,
ends to and rise from the ends of the sleeve 28. The guides 31, 32 are spaced'apart in the pairs and are connected rigidly by a crossbar 33 at their upper ends.
A saw-carrier is mounted slidingly in the guides 31', 32 and a saw 43 may be mounted slidingly in the carrier. The saw-carrier is constructed as follows: Plates 34, 35 are arranged parallel with each other between and in contact with the inner faces of the guides '31, 32, andare connected at their upper and lowerends by cleats 36, 37. Lugs 38 are fixed to the outer faces of the plates 34, 35 and slidingly engage the adjacent margins of the guides 31, 32 and steady the carrier in 'vertica movement in the guides. Sawguides 39, 46 are mounted horizontally arranged in pairs, are fixed at 'their lower transversely of the inner faces of the plates 34, 35 and the end portions of said guides project from the front and rear margins of the plates and are slightly closer together than the centers thereof. The saw-guides 39, are arranged in pairs and the pair 40 may be adjusted to greater altitude by removing thescrews 41 from the holes. in which they are shown in the plates 34, 35 (Fig. 2) and raising the guides and replacing the screws in the holes 42 in said plates. is provision made for raising the guides to compensate for wear of the saw 43. The guides 39 S11 port and receive sliding engagement of t 1e back 44 of the saw and prevent downward movement of the saw independent of the carrier. The guides 39, 40 on opposite sides of the saw maintain the blade parallel with theplates 34, 35 of the carrier. A stop 45 is mounted adjustably on one of the guides 31 and is adapted to be engaged by and limit downward movement of the saw-carrier. A detent 46 is ivoted on the cross-bar 33 and is held'yieldlngly in one direction by a spring 47. A stud 48 on the cleat 36 is adapted to be engaged by the detent 46 to hold the carrier and saw in the uppermost limit of movement thereof,when the saw is not in use. The detent may be moved manually to release the stud 48 and permit the carrier and saw to descend for the use of the saw as shown in Fig.2. The sleeve 28 is further connected to its journal by a cap screw 49 seated in the rear end of said journal. Back- plates 50, 51 are provided, of like construction, each late having one straight end and one beve end. The straight ends of the plates 50, 51 are beveled back as shown in Fig. 1. The back plates 50, 51 are secured to the base or bed 10 by cap screws 52 mounted through notches in the lower margins of the lates' and seated in the base. In the use 0' the miter box in cutting at right or acute angles with the saw and its carrier and guides u right, the back plates 50, 51 are positione as shown with their straight edges near each other and spaced apart for the passage of the saw between them. When miter or under-cuts are to be made, the screws 52 are loosened and one or the other or both of the back plates are removed and interchanged or reversed and replaced and tightened by the screws 52 .with the inclined'ends of the plate or lates toward the center, as shown by dotted lines in Fig. 'Then the saw, carrier, and guides may be tilted in either direction to an angle of 45, by first removing the key .30 from the sleeve 28 and its journal and re lacing said key in the new the journal.
Work-holders are provided and are constructed as follows: A tubular screw 53 (Fig. 5) is seated in a hole in the base 10 adjacent the inner end of either of the back plates 50, 51 and a pointed pin 54 is screwed through said tubular screw. The pin 54' is work on said base Thus 10 (Fig.7).
