Title: Improvements in or relating to a wood-working machine such as a circular sawing machine
IPC: B23Q3/00
Filed: 1951-01-19
Abstract: 692,317. Woodworking fences. KEARNEY & TRECKER CORPORATION. Jan. 19, 1951 [Jan. 21, 1950], No. 1481/51. Classes 145 (i) and 145 (ii). A work fence or gauge for a woodworking machine such as a circular or band saw, or a shaping machine; is so constructed as to be movable towards, or away from, the tool and to be self aligning normal to the axis of the cutting tool. As shown, fence 19 is arranged normal to the carriage 20 and parallel to a circular saw 16. Carriage 20 is slidable on a guide bar 23 and has horizontal and vertical surfaces 28, 30 which bear thereon. Contact shoes 36, 37 are resiliently urged towards the carriage, and engage the rear surface 38 of the guide bar. These contact shoes hold the carriage and fence in correct alignment whilst allowing it to be moved to vary the fence-saw distance. Knobs 39-40 are provided to allow the shoes to be released, in order that the carriage and fence may be removed from the guide bar. To minimise friction when the fence is being adjusted, a narrow bearing surface 44 is provided on the fence to ride on the table 15. To lock the carriage and fence the fence and its support member 47 are displaced leftwardly (in the Figures) so that locking element 45 engages the edge 27 of the table, the action being produced by the clamp lever 63 pivotably carried by the housing 64. The surface 30 of carriage 20 is forced rightwardly by the clamp lever and engages the guide bar so that the fence and carriage are clamped. In the unclamped position of the lever, a compression spring moves support 47 and carriage 20 in the opposite directions to unclamp the assembly. The clamping is effected by a cam 69. Fig. 3 shows the assembly clamped and in Fig. 1 it is released. To control the fine transverse displacement of the carriage, the bracket 76 is clamped by screw 88 to the guide bar and the adjustment effected by the adjusting screw 74. The screw is received by a slot in the bracket and may be disconnected when the carriage is to be removed from the machine. If desired the bracket can be mounted on the other side of the carriage and then the screw 74 is threaded into a duplicate lug 89. A clearance 93 on fence 19 lessens the danger of kickback. In a modification (not shown) an extra guide bar is provided at the rear of the table and the clamping means force the carriage and fence apart to clamp between the guide bars. Alternatively the table has a dependent flange at the rear and a hooked portion of the fence engages inside the flange, which then replaces the extra guide bar.

A typographical line-composing machine wherein a selection device renders the quadding mechanism effective or ineffective according to the line is shorter than or exceeds a given length comprises a thrust member carried by the support for the long finger of the linedelivery carriage, travelling with and extending in the direction of travel of the carriage, and an adjustable member located in the path of the thrust member and carried by a slide connected to the selector device and adjustable towards and away from the thrust member for pre-setting to the required measure. A stop 18, Fig 2 is manually adjusted in accordance with the required line length and limits the leftward movement of the long-deliveryfinger-carrying block 16, which carries a rod 44. A gauge block 38 carrying a lug 43 is adjusted by means of a latch 39 along a bar 24 having an em-scale 25, being set at from one to three ems short of the line length. The bar 24 is urged to the right by a spring 28. If the line is too short for justification, the quadding apparatus acts normally, otherwise the rod 44 strikes the lug 43 and moves the bar 25 to the left whereupon a fin 31 on the bar releases a lever 32, which is thereupon moved by a spring 35 to close a switch 33. A cam 45, Fig. 4, normally acts through arms 49, 50 51 to operate the vice-jaw-control lever 55 for quadding. The arm 49 carries a jaw 57, a rotary solenoid 65, and a bolt 62 connected to the rodless arm 64 of the solenoid. The arm 50 carries a jaw 59 pivoted at 60 to the arm 49. Normally the bolt 62 engages in a recess 68 in the jaw 59 to lock the arms 49, 50 together. Closing of the switch 33 energizes the solenoid 65 to withdraw the bolt 62 and render the quadding apparatus inoperative. In another form, Fig. 8; the rod 44 is replaced by a rod 80 having teeth 82 whereby the block 16 is adjustable on the rod by means of a latch 81 for line length. A quadrant 86 is manually rotatable on the carriage stop plate 23 so as to present in alignment with the rod 80 a stud 88, a stud 89 or a surface 90, giving a measure respectively three, two and one em short of the line length. Engagement of the rod 80 with the quadrant 86 closes the switch 33. According to the Provisional Specification, a finger on the first elevator engages, when the elevator descends to casting position and if the line is of sufficient length, an upstanding arm on a block adjustable on a horizontal shaft according to line length, to rotate the shaft and depress a vertical thrust rod to close the switch.
