4 Claims.
This invention relates to driving mechanism and is herein illustrated as embodied in a press of the type commonly known as a clicking machine such as that illustrated in United States I Letters Patent No. 921,503, granted May 11, 1909, upon an application filed in the name of Arthur Bates and comprising a work supporting bed, a reciprocating post and a presser arm extending laterally from the post and movable there- 10 with over the bed and toward and away therefrom for exerting pressure applying operations positioned upon work supported by the bed to produce blanks. of application Serial No. 547,546, filed June 29, 15 1931 in our names.
It is an object of the present invention to provide an improved machine of the type referred to which, without sacrificing any of the characteristic advantages of such machines as 20 heretofore built, will be so constructed as to facilitate the removal of certain parts for adjustment and servicing.
To this end and as illustrated, the machine is provided with a flywheel carried by a shaft 25 for reciprocating the presser member and which is driven by a motor mounted upon the frame of the machine for movement relatively to the flywheel in such manner that the motor and flywheel can readily be disconnected when it is 30 necessary to remove the flywheel. Preferably,
and as shown, the motor is carried by a bracket pivotally mounted upon the frame, and means is provided for releasably securing the bracket in position with the motor operatively connected 35 to the flywheel.
The invention is disclosed. in the following detailed description and in the accompanying drawings and will be pointed out in the claims.
In the drawings,
40 Fig. l is a front elevation of a machine illustrating one embodiment of our invention;
Fig. 2 is a side elevation of a portion of the machine illustrating the motor driven mechanism;
45 Fig. 3 is a detailed view partly in section of a motor bracket locking device; and
Fig. 4 is an end view partly in section of a portion of the locking device.
As illustrated in Figs. 1 and 2 of the drawings,
50 the machine comprises a C-shaped frame Ill upon one side of which is slidably mounted a hollow upright post l2 to which is secured a presser member or arm !4 arranged for cooperation with a cutting block I5 mounted upon the 55 opposite side of the frame, to operate on work,
This application is a division' such as leather or other sheet material, positioned upon the bed. As is customary in machines of this type, the post I2 is movable angularly about its axis so that the presser arm l4 secured thereto can be moved over the bed [6 5 about the axis of the post, for example into operative position relatively to a freely movable cutting die located upon the work. The post is arranged to be reciprocated vertically by a connecting rod 18 operatively connected to an eccentric it upon a rotary shaft 20 which is controlled by a one-revolution clutch, not shown, for causing rotation of the shaft 20 by a flywheel 22 driven by a motor 24 supported on the frame. 7 Preferably, and as shown in Figs. 1 and 2, the motor 24 is supported on a bracket 26 depending from a shaft 28 pivoted in ears 30 on the frame [0. The flywheel 22 is provided with a circular rack 32 which is arranged to engage a pinion 34 on the motor. The flywheel also has flanges 36 which act as guards to prevent injury to the teeth of the rack 32. These flanges would operate to prevent withdrawal of the flywheel unless the pinion and flywheel were relatively movable radially of the flywheel. However, the pivotal mounting of motor bracket 26 makes it possible to move the pinion 34 out of the line of movement of the flanges when it is necessary to remove the flywheel from the shaft 20. In order to lock the motor bracket in position with the pinion 34 in mesh with the rack 32, the motor bracket 26 is provided with a depending portion 38 having a slot 43 within which is positioned a retaining bar 42 (Figs. 1, 2, 3 and 4). The bar 42 is arranged for pivotal movement about a shaft 43, Fig. 1, and carries a spring 44 bearing against washers 45 in engagement with a pin 46 on the bar and a boss 41 on the motor bracket, the spring being normally operative to force the motor bracketoutwardly. The end of the bar 42 is provided with an elongated slot 43 within which is located a retaining pin 50 and which is supported in the portion 38 of the motor bracket. At one end of the slot 48 the bar 42 is provided with a tapered recess 52 adapted to receive a correspondingly tapered portion 54 of the pin 50. The tapered portion 54 terminates in a shoulder 56 which, when the bracket 26 is swung outwardly from the frame of the machine, rides upon the outer side of the bar 42, the shoulder being forced into engagement with the bar by a spring 58 which surrounds a reduced end portion 553 of the pin 50. When it is desired to place the pinion 34 and the rack 32 in mesh,
a convenient means whereby the removal of the flywheel is facilitated.
Having described the invention, what we claim as new and desire to secure by Letters Patent of the United States is:
1. A machine having a frame, a shaft mounted in the frame, a flywheel on the shaft, a bracket mounted upon the frame for movement toward or away from the flywheel, a motor secured to the bracket and having a pinion adapted to engage the flywheel for driving the same, means tending to force the bracket outwardly from the flywheel,
a link pivoted upon the frame and extending into engagement'with the bracket and manually-controlled means on the bracket for engaging the link to lock the bracket in position with the pin- 7 ion in engagement withrthe flywheel.
2. A machine having a frame, a rotary shaft, a flywheel carried by the shaft, an electric motor for driving the flywheel, a bracket pivotally mounted upon the frame and secured to the motor for supporting it, a member secured to the frame and extending loosely, through the bracket, a spring, on said member operable normally to force the bracket and motor outwardly from the frame, and, manually operable means mounted upon the bracket and arranged to engage said member for securing the bracket to the flywheel, means for supporting the motor comprisinga bracket pivotally mounted upon the frame, a spring normally operative to force the bracket outwardly of the frame to release the pinion from the rack, and cooperating means carried by the bracket and the frame operable upon movement of the bracket inwardly to secure the bracket in position with the pinion and rack in mesh. 1 V
