MECHANICAL MOVEMENT.

Application filed September 22, 1926. Serial No. 1365934.

This invention relates to improvements in a mechanical movement and has for one of its principal objects the provision of a ma chine which utilizes the energy imparted by the momentum of a comparatively heavy pendulum in motion.

One of the important objects of this invention is to provide a machine embodying a pendulum which, while swinging, will 1mpart motion to a rotatable drum, which drum in turn then operates additional elements in conjunction with the said pendulum, said additional elements comprising a system of gears and a plurality of pulleys, thereby changing oscillatory motion of the pendulum to rotary motion of the pulleys.

One of the further important objects of this invention is to provide a device which by its mechanical movements will demonstrate the action of a pendulum and which will further convert the swinging movement of said pendulum into a continuous rotary motion. Other and further important obtrating the pendulum at its central position.

Figure 5 is a side elevation of the operating drum with its bar-groove.

Figure 6 is a side elevation illustrating another face of the drum.

As shown in the drawings:

The reference numeral 10 indicates generally the base or bottom of the improved machine of this invention and is preferably of heavy material and has upstanding supports 12 from the top of which a pendulum 14 is swung. This pendulum is positioned at the front of the apparatus as shown in 5 the figuresand a slot 16 is formed in the triangular bob of the pendulum; this slot Figure 4 is a central vertical section illus- I being for thereception of an operating ball or the like 18. This ball in turn fits into a cam-groove 20 in a drum 22, which'drum is mounted upon a shaft 24 which passes transversely across the machine and is mounted in suitable bearings.

For the purpose of producing a. more uniform operation a flywheel 26 is mounted on one end of the shaft 24. v

Upon the other end of the shaft 24 is affixed a gear 28, which in turn meshes with a pinion 30 mounted upon a corresponding shaft 32 upon which is also positioned a pair of pulleys or the like 34. Also mounted upon the 'shaft24 is a pair of members adapted to operate in conjunction with the pendulum 14 and which are S-shaped as shown, being designated by the reference numerals 36. These pendulum operating members or finger bars are so mounted on the shaft 24 with relation to the drum 22 and the pendulum 14 that the upper hook of one of the finger bars 36 will a contact at all times with the upper face of the triangular bob of the pendulum 14. This position is best shown in the full lines in Figure 2.

When the pendulum swings to the other extreme of its movement, the finger bar at the right will gradually follow it down, contacting with the face of the triangular bob, this being due to the rotary motion of the drum 22 and itsshaft 24, upon which the finger bar is aflixed. This action will continue until such time as the pendulum has reached the other extreme limit of its movement as shown in the dotted lines in Figure 2, when the finger bar 36 on the right will be allowed ,to pass around the end of the pendulum. At this point the upper hook member of the finger bar on the left comes into. contact with the corresponding face of the pendulum hob and the action above de scribed is repeated.

At thesame time the ball 18 moves in the groove 20 imparting a rotary motion to the drum 22. r

In Figure 6 the groove 20 is shown at the point where the return movement of the pendulum begins from the extreme righthand position.

The ball 18 rides in a horizontal path along the top edge of the plate 38 forming a front portion of the frame of the machine as best shown in Figures 2 and 4.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range Without departing from the principles of this invention; and I therefore do not purpose limitfl ing the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention: In a machine for converting swinging into rotary motion, a pendulum, means for sup- 10 porting the same, a rotatable drum also mounted in said means, and a driving connection between the pendulum and said rotary drum, said connection including a triotion reducing ball bearing, said ball bearing mounted conjointly in a slot in the pendulum and a groove in the drum and guiding means to support said ball.

In testimony whereof I affix my signature.

GEORGE T. BASLER.
