POWER REVERSING MECHANISM.

Specification of Letters Patent. Patented Sept. 1920. I

Application filed March 20, 1919. Serial-No. 283,842.

To all whom it may concern Be it known that I, THEODORE RAYMOND CAMERON, a citizen of the United States,

residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Power Reversing Mechanism, of which the following is a specification.

My invention relates to a mechanical packing apparatus, adapted for use in connection with a power operated press,' such as a cotton press, while not necessarily restricted to this use. j

An important object of the invention is to provide automatic means for causing the platen of the packer to reciprocate continuously during the operation of the appara? tus, such means'being of simple construction and convenient to control in its operation. 1 I

A further object of the invention is. to provide apparatus of the above mentioned character adapted for connection with the head platen. of, the power press, in conjunction therewith for packing cotton or the like in the press box, before the press box is placed in the power press.

. Other objects and advantages of the invention will be-apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like: parts throughout the same, i I

'- Figure 1 is a side elevation of apparatus embodying my invention; Fig. 2 is a horizontal sectional view, on line 2-2 of'Fig. 1; A

' Fig.3 is a transverse sectional view, taken.

on line'33 of Fig. 2; and,

.Fig. 4 is an end elevation of the same. 7 In the drawings, wherein fortherpurpose of illustration is shown-a preferred embodi-- ment of my invention, the numeral 5 desig:

nates the head platen of the power press, supported-by a pipe or tubular, post 6.

My apparatus comprises ably horizontal frame,',including spaced longitudinal beams 7 rigidly connected at theirinner ends by a transverse beam 8, having an opening formed therethrough for the upper end of the post 6, such post being screw threaded for the reception of a nut 9. At its opposite end, the longitudinal beams to be usedv taken a main prefer 7 have connection with posts 10 by means of bolts 11. v v

The numeral 12 designates a gear case asa whole, formed in upper and lower sections 1 13 and 14, these sections being secured together by bolts15, engaging the longitudi-. nal beams 7 1 A transverse frame 16 is alsoprovided, including beams bolted to the beams 7 as shown at 18. The beams 17 are connected at their outer ends by a beam 19.

The numeral 20 designates a platen, which is rigidly secured to ram posts 21, by means of sockets or couplings 22 of any well known or preferred construction. These ram-posts are slidably mounted within guide sleeves or sockets 23, rigidly secured to the gear casing 12, and preferably carried by. thelower portion thereof. At their upper ends, the ram-posts 21' are rigidly connected with a head-yoke 24, by means of sockets orf couplings 25. y 1 l V Rigidly secured to the head-yoke 24; and the platen 20 are sockets or castings 26, rig-. idly receiving the ends of a vertically operating screw 27 to hold it against turning movement, as shown. This screw extends through the gear casing 12, as will be more fully explained. p

A horizontal transverse drive shaft 28, is through bearings29 and 30, and

j ournaled 32 and 33 arranged upon opposite sides thereof, as shown. The shaft 28, as more clearly shown in Fig. 3, has 34;, rigidly secured thereto, and vertically arranged. This beveled gear engages a horizontally beveled gear 34" having a nut; 35 keyed or 'rigidlyconnected therein, for rotation therewith. .The nut 35 has screw threaded engagement with the operating gear 34:. The gear 34 is provided in" its top with a race-way 35, receiving'rollers'37 traveling in a race-way formed in the gear casing section 13. The gear 3 1 is also provided with a depending annular flange 38, cooperating with-faflange 39;formed upon the lower gear casing 14:; -The gear a beveled gear casing sections 13 and 14: provide an annular gear 34 the'operat 3 pulley 33, by means to be described. belts 41 and 42 may engage a common tight ing screw 27' will be made to travel longitudinally. z

, The numeral 41 designates an open belt, While 42 designates a crossed belt. open belt 41 is adapted to be shifted from the loose pulley 33 to the tight pulley 31,;

and vice versa, and the crossed belt 42 is adapted to be shifted from the tight pulley 31 to the loose pulley 32 and vice versa, and also from the tight pulley 31 to the loose The outward movement of the carrier 47 is limited by a transverse pin 49. The recipr catory carrier 47 has pivotal connection with a link 49, pivoted to the lower end of a verticallyswinging upstanding lever 50, rigidly secured to a rock shaft 51. The lever 50 is provided near its upper end with a weight 52 tending to hold the same in either position uponvopposite sides of its pivot.

I 7 The rock shaft 51 has a tappet lever 53 rigidly secured thereto, and arranged in wardly of the beam 17, as clearly shown in Fig. 2.

. The tappet lever 53 is adapted to be alteri nately engaged by tappets 54 and 55, ar-

ranged near the upper and lower ends of the ram-posts 21, and secured thereto by rings 55. These rings are clamped to the ram-post 21 and the tappets are longitudinally adjustably mounted within openings '"formed in extensions of the ring, and

clamped therein by bolts 56. V

A manually operated lever57 is pivotally connected with the transverse portion of the carrier 47 and has pivotal connection with'a link 58, secured.to the beam 17. The

' lever projects upwardlybeyond its pivotal connection with the link 58, and when the upper end thereof is swung rearwardly sufiiciently, the lower end of the lever is adapted to enter a notch 59 of a latch lever .60,"whereby the lever 57 may be locked in the adjusted position. Then the lever 57 V is swung to its extreme position, the belt 41.

' remains uponthe loose pulley 33 but the belt 42 is shifted from the tightpulley 31 onto.

the apparatus then re the loose pulley 32, maining idle. V V

In operation, when the belt 42 is shifted from the loose pulley 32 onto the tight pulley 31, the belt 41 thenengaging the loose pulley 33, the shaft 28 may be; rotated to cause the gearing to raise the. operating screw The These arms shifted to the tight pulley 31. It is obvious that this shifting of the belts causes the gearing to operate in a reverse direction to lower the screw 27 and platen. The platen will now continue to move downwardly; until the upper tappet 55 contacts with the tappet lever 53, swinging the same down wardly'whereby the belt shifting mechanism returnsthe'belts to the otheroperating position. This operation continues automatically, whereby the platen 2O recipro rates continuously during the'operati'on' of the machine. 7

When it is desired to while the tappet lever is out of contact with both tappets, the lever 57 is shifted rearwardly to the extreme position, thereby causing both belts 41' and 42 to engage the loose pulley 33. The lever 57 may be locked in this position by engaging within the notch 59.

It is to be understood that the form of my invention herein shown and described is to be. taken as the preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to withoutldeparting fromthe spirit of the inventionor the scope of the subjoined claims.
