Filed: 1918-12-18
Abstract: 136,284. McInroy, T. Dec. 18, 1918. Cylinder machines.-The cylinder of a stop cylinder machine is driven by a single wheel loose on the cylinder shaft and gearing with a rack on the bed, the wheel being connected to the cylinder during the printing stroke bv the usual starting-pawl and by a locking-device which locks the wheel and cylinder firmly together so a.s to prevent slur in the impression. In one form, Fig. 1. a double-ended pawl 3, pivoted by a pin 4 to the loose wheel, forms at one end the driving-pawl 8, and at the other end a locking-pawl 9. The pawl 3 is mounted in a groove 2 in the end of the cylinder 1, and, during the printing stroke of the bed. the ends 8, 9 engage notches 10, 6 in the walls of the groove, and the cylinder and loose wheel are locked together. Near the end of the printing stroke, an incline 13 is raised by a cam into the path of a roller 12 carried by the pawl so as to move the pawl 9 out of the notch 6. The pawl 8 remains in driving engagement with the notch 10 throughout the printing stroke; but. if it is desired to trip the cylinder, the incline is raised farther to disengage the pawl 8 from the notch 10. During the non-printing stroke, the pawls trail idly in the groove 2 until the end of the stroke, when the fall of the incline 13 permits re-engagement of the pawls with the notches. In a modification, separate locking and driving pawls are provided, the locking-pawl being actuated by a stationary or cam-actuated incline. In a further modification, Fig. 6, the locking-device comprises a plunger 11 mounted in a boss 9 in the loose wheel L and connected bv a double lever 21 to a second plunger 14, on which acts a spring 15 tending to move the plunger 11 into locking engagement with a hole 13 in the cylinder 1. A stationary or cam-actuated incline 24 mounted on the frame K arts upon the plunger 14 at the end of the printing stroke to withdraw the plunger 12 from the hole 13.

Abstract: 460,441. Hinges. COOPER, H. C. July 25, 1935, No. 21154. [Class 65 (ii)] A joint for an electric-light bracket, of the kind comprising members pivoted together with an electric cable passing along the members, comprises a pair of lugs on each member connected by links, the lugs and links being spaced apart to accommodate the cable between them, and interengaging means between opposed lugs for controlling the pivotal movements of the lugs and links independently of the cable so that the extents of movement of these parts relative to each other have predetermined ratios. In the form shown, pairs of lugs 20, 21 are welded to the respective bracket members 28 and are connected by links 23, 24 pivoted to them by bolts 31, the parts being spaced to allow freedom for the cable 30 between the links 24, which are shown connected by a web 32. The lugs 20, 21 are formed with sets of interengaging teeth 22, which control the motion about the bolts 31 so that the members 28 always make equal angles with the links 23, 24. Hard steel washers are interposed between the links and the lugs 20, 21 to produce sufficient friction to hold the members in any position. In a modification, a single pivot bolt is used for each pair of lugs instead of the two short bolts 31, and spacing sleeves are threaded on these bolts between the links 24, the web 32 being dispensed with ; the cable is threaded between the bolts. More than two pivotal axes may be used, additional links being then used and the links being provided with teeth similar to 22, except at the ends where they join the members 28, to control the motion in the same way. The links may be made longer than those shown, in which case they carry a pair of idle gear-wheels to connect the toothed sectors 22 ; one pair of links (23 or 24) may be dispensed with. Two or more of these joints may be used in series, and a universal joint may be formed by placing two of these joints with the axes of one perpendicular to those of the other. According to the Provisional Specification, instead of the movement being equalized at the respective pivots, the movement at each pivot may be free but is limited to the same value at each pivot.
