Title: Improvements in electric motor driven chiming and striking mechanism of clocks
IPC: G04C21/08
Filed: 1948-08-13
Abstract: 648,495. Clocks. COPE, W. W. Aug. 13, 1948, No. 21355. [Class 139] In a clock the striking and chiming mechanisms are driven by separate electric motors. When one of the pins 10, Fig. 1, on a disc 11 rotated from the time train at one revolution per hour raises a rocker 9 a pivoted bell-crank lever 8 is rocked clockwise and a link 5 attached thereto is moved to the right until a pin 13 thereon leaves the top of a tumbler 14 whereupon the link 5 falls and a notch 6 therein engages a pin 7 on the upper arm of a pivoted two-armed lever 4. When the pin 10 passes the rocker 9 a spring 12 pulls the link 5 to the left and the lever 4 is rocked counter-clockwise so that its lower arm depresses a plunger 3 and closes a switch 2 to start a motor 1 which drives the chiming train. The tumbler 14 is pivoted on a T- shaped lever 15 the stem of which carries a pin 17 which co-operates with the usual count wheel 18 in such a way that at the end of the " chime" the lever 15 and tumbler 14 are rocked to move the link 5 and release the pin 7 from the notch 6 thus opening the switch 2 and stopping the motor 1. Just before the hour a pin 30 on the count wheel 18 rocks a three-armed lever 27 counter-clockwise to release the rack hook 24, free the rack 21 and at the same time move a link 31 to the left until a notch 32 therein engages a pin 33 on the upper arm of a pivoted two-armed lever 34. When, on the hour, the lever 27 is freed by the pin 30 the spring rocks it clockwise and the link 31 in moving to the right rocks the lever 34 clockwise to depress a plunger 3 and actuate a switch 35 to start a motor 36 which drives the striking train. The rack 21 is gathered in the usual manner and on the return movement of the rack hook 24 the lever 31 frees the lever 34, the switch 35 is opened and the motor 36 stops. A cam 42 is secured to the count wheel 18 and co-operates with a lever arm 41 attached to the lever 4 in such a way that at the hour the link 5 is required to make an additional movement to the right to engage the notch 6 with the pin 7. This additional movement is obtained by placing the corresponding pin 10 nearer the circumference of the disc 11 than the other pins 10. The chiming mechanism will therefore always be brought into its true phase relationship with the timing train at the hour. This could also be effected in the usual way by making the count wheel notch 20, which the pin 17 enters after chiming " threequarters," deeper than the others.

Title: Improvements in inking devices for rotary duplicators
IPC: B41L13/18
Filed: 1919-09-02
Abstract: 154,701. Bosc, L. P. Sept. 2, 1919. Inking-apparatus. - An internal inking-apparatus for rotary duplicators of the kind described in Specification 119/09 in which the duct and its roller are movable so that the roller applies the ink directly to the printing- cylinder, or indirectly through co-operation with another roll with which it is brought into contact by the operation of an external lever fitted with a pointer moving over a graduated scale is constructed with a distributing roller of spongy ma- .terial arranged in front of the indirect inking-roller. The apparatus is formed with a pair of vertical plates as 4 for receiving pins which co-operate with recessed guides 11, 12 fixed to a platform 10 upon which the duct can move horizontally on wheels 20, 21, constrained by angle-iron guides 19. The plates 4 are connected by cross-bars 7, 8, 9, and together form a frame which is fixed to a hollow axle 2 upon which the stencil drum 1 rotates. The movement of the ink-duct is controlled 'by a lever 29 on a shaft 28 mounted in the hollow axle 2, and this lever raises and lowers the platform 10, by means of links 26, 25, and as the duct moves vertically it is compelled to move horizontally also by the engagement of pins 24 in diagonal slots 23 in the plates 4. The lever 29 is fitted with a pointer 31 and locking-stud 32, the pointer moving over a scale 31. In the position of the duct and roller 30 shown in Fig. 1, the amount of ink supplied varies with the pressure of the roller 30 on the d'rum, and this is controlled by the lever 29. When the lever 29 is moved to bring the roller 30 into contact with an ink-applying roller 38, mounted in spring-controlled arms 39 governed by adjusting screws 42, the pressure of the roller 30 on the roller 38 is also governed by the lever 29, but in this case the ink supplied varies inversely as the pressure. To effect this, pressure pins 46 on the duct are received between arms 44, 45, on a ring carried by the shaft 28, and the arm 45 presses on the studs and with the desired pressure, and the ink is distributed by a roller 48 of spongy material. In the intermediate position of the lever 29, the roller 38 may be used to remove ink from the cylinder 1. This is effected by a pivoted scraper 56 which is normally out of contact with the roller 38, but can be caused to engage the same by means of cam-controlled hooks 59 in front of the duct. The roller 30 is fitted with an adjustable scraper 34, controlled by a spring 37. The ink is distributed by spring- mounted rolls 48, 51 connected by a link 54, and so arranged that if one is operative the other is inoperative. The cylinder is preferably fitted with two circumferential angle-bars which facilitate the removal of the ink by tending to form a pool which can be taken up easily by the roller 48 of spongy material. The lever 29 may be duplicated on the other side of the machine, each end of the duct being thus independently adjustable.

Filed: 1926-09-03
Abstract: 273,928. Marks, E. C. R., (Collins Co., J. N.). Sept. 3, 1926. Machines for making boxes. A receptacle forming machine comprises means for feeding a blank into position to be acted upon by folding means which partially form it into a receptacle open at one side and a pair of endless chains or bands provided with projections adapted to form between them a series of pockets or dies, each adapted to receive a partially formed receptacle, and movable to present the partially formed receptacle to means adapted to complete the folding operations. The machine is so arranged that a blank, Fig. 23, fed from a pile is partly formed into an open-sided receptacle by stationary dies and the formation completed by the dies constituted by the pair of endless chains which then move the formed receptacle beneath a device for filling it with a predetermined number of similar articles, such as wrapped candy, and finally pass the filled receptacle to a delivery conveyer. The machine comprises a main shaft 69, Fig. 3, mounted in a frame formed of front and rear plates 31, 32 which support a table 30. The shaft 69 drives through gears 71, 72, a shaft 67 which rotates, through bevel gears 66, 65 a crank arm 61, the arm being connected by a link 57, lever 53 and link 55 to a reciprocating feed slide 42 adapted to feed the lowermost blank from a pile along spaced rails 52 on to stationary dies 74, 78 (Fig. 1) of which the die 78 is resiliently mounted on the head of a T-shaped member 79. The dies lie beneath a plunger 91 mounted in a bracket 83 on the table 30 and adapted to be reciprocated through link and lever mechanism by a face cam 217 on the shaft 67 to force the blank between the dies and thereby fold up its sides a, Fig. 23, whereupon the ends b of the sides are folded over by pairs of spring-pressed rods 104, 113 slidably mounted on the die 74 and acting successively under the control of cams 106, 115 which are mounted on a shaft 108 continuously rotated by the main shaft 69 and engage cross bars 105, 114, connecting the outer ends of each pair of rods 104, 113. The plunger 91 now descends further, pushing the partly formed receptacle on to the table 30 between arms 122, Fig. 2, on the endless chain 121, the arms and table forming a die in which the formation of the receptacle is completed. The chains are mounted on sprockets 118, 119, the former being driven through a Geneva stop-wheel mechanism by the shaft 69. By this last movement of the plunger 91 the parts 39 of the blank are turned upright, ready, when the chains 121 complete their next movement, to be folded over by spring urged pivoted fingers 144 actuated by cams 156 on the shaft 69. The receptacle then passes beneath the first of three plungers 157, 185, 200, Fig. 1, mounted on a crosshead 158 adapted to be reciprocated through lever and link mechanism by the face cam 217. The plunger 157 completes the formation of the receptacle by entering it, folding down into it the ends 39, and by squaring its walls.
