To all 107mm it may concern:
Be it lmown that I, JAM-ES H. CoLToN, a citizen of the United States, and a resident of the city :andcounty of San Francisco, State of California, have invented certain new and useful Improvements in Sack- Turning Machines. of which the following a specification.
The invention relates to a machine for turning empty sacks or bags inside out.
An object of the invention is to provide a sack turning machine in which the sack maybe readily placed and from which it may be readily removed when turned.
Another object of the invention is to provide a power driven sack'turning machine.
ii. further object of the invention :is to provide a power driven sack 'tur ning machine which is automatically thrown out of operation when the sack is completely turned inside out.
The invention possesses other advantageous features, some-of which, with the foregoing, will be described at length in the following specification, where I shall :outline in full, that form of the invention which 1 have selected for illustration in the drawings accompanying and forming part-:of'the present specification. In such drawings, I have shown only one specific form of my generic invention, but it :is to be understood that I do not limit myself to such form because my invention be embodied in a multiplicity of forms, each being a species of my said invention. It is also to be understood that by the claims succeeding the description of my invention,- I desire to cover the invention in whatever form it may be embodied.
Referring to said drawings, Figure l is a front view of the machine of my invention. Fig. 2 is a side view of the machine. Fig. 3 is a top or plan view of the machine. Fig. .1: is a section taken on the line l2 Fig. 1. V
The sack turning machine of my invention comprises a suitable frame composed of the upright rails A., the lateral or horizontal rails l3. secured to the rails A... at their upper end and the cross rail 0. connecting the rails B. and bracing the frame. Secured to the rails A. adjacent their upper ends is a cross bar 5, to which is attached the depending bar 6, to the lower end of which is secured the loop or ring D.
been turned inside out. shaft J, is a friction wheel K. Rotatably Therails A. serve as guides for the cross head 7, which is movable longitudinally of the rails 21., said cross head being guided in its movement by rollers 8 bearing against the rails A. The rails A. are preferably formed-ofT rails and the rollers S are preferably'grooved and engage the stem of the T. Secured to thecross head 7 is a pusher or plunger which is provided with an elongated head 9. The pusher E. is positioned so that when it is raised it passes through the loop or ring 1)..
Means are provided for producing a vertical reciprocating .movement of the cross head'T. Journaled on the rails B. is a transverse shaft J., to. the opposite ends of which are securedthesheaves G. Secured to and passing around each sheave G. is a rope or other flexible connector F. which, issecure'dat its lower end to the cross head '7. Hanging from the other side of each sheave is a counterweight I. which is attached to the flexible connector H. which passes around the sheave in the opposite direction to rope F. and is secured thereto. The combined weight of the co-unterweights is less than theaveight of the cross head and its attached elements and the purpose of the-counterweights is to orevent the cross head from descending too rapidly after the pusher has operated to turn the empty sack inside out.
.Mea-ns'are provided for actuating the cross head by power for controlling therapplication of the powerand for automatically releasing the power drive when the sack has Secured to the mounted on the shaft L., which is mounted in the bearings M. on the rails B. is a friction wheel N. which is arranged to be moved into and out of engagement with the friction Wheel K. The drive pulley O. is secured to the friction wheel N. and the pulley 0. may be driven by a belt or other suitable means. Y
Secured to the shaft L. are eccentric bushings T. which are journaled in the bearings M., so that partial rotation of the shaft L. serves to vary the center of rotation of the friction wheel N. is a lever P. which is connected by the rod R. with the control lever Q. Depression of the control lever Q, causes a partial rotation of shaft L. and brings friction wheel Secured to the shaft L- I N. into contact with friction wheel K. therei by causing a rotation of shaft J. and an elevation of the pusher E. lhe lever P. extends beyond the shaft L. and into proximity to the friction wheel K. Secured to the side of friction wheel. K. is a projection or abutment S. which, as the wheel rotates, comes in contact with the projecting portion of lever P. and moves the lever to release the contact between the friction wheels and thereby stop the upward movement of the pusher. The abutment S. is so placed that it operates to disengage the power drive when the sack has been turned inside out. After the power drive has been released, the pusher descends to its normal position.
In operation, the sack to be turned is slipped over the loop 1)., so that the loop and part of the bar 6 are inclosed in the sack. The lever Q. is then depressed and the plunger moves upward, forcing the sack, closed end first through the loop, thereby turning it inside out The pusher then descends leaving the turned sack free from the machine so that it can be easily and quickly removed. The bar 6 being secured to the rear side of the loop, does not offer any resistance or obstruction to the placing orremoval of the sack and sacks may be turned very rapidly and efficiently.
I claim:
1. In a sack turning machine, a loop adapted to be encircled by the open sack, a pusher arranged below the loop and adapted. to reciprocate through said loop, means for moving the pusher with respect to the I loop and means for disengaging the said moving means from the said pusher.
2. In a sack turning machine, a frame, a depending bar on said frame, a loop attached to the lower end of said bar, a vertically movable pusher guided on said frame arranged below and in alinement with the center of said loop, poweroperated means for moving said pusher vertically through said loop and means for disconnectingsaid power operated .means from said pusher.
3. In a sack turning machine, means for holding the sack extended, a pusher for pushing the closed end of the sack through said means, power operated means for moving said pusher and means for automatically disengaging the power operated means from said pusher.
4. In a sack turning machine, means for between said sheave and pusher, a frictionwheel connected to said sheave, a frictlon drive wheel arranged adjacent said first named wheel, means for moving said friction wheels into engagement and automatically operated means for moving them out of engagement.
6. In a sack turning machine, means for holding the sack extended, a pusher for pushing the closed end of the sack through said means, power operated means for raising said pusher, means for disconnecting said power operated means fromthe pusherand counterweights to retard the descent of the pusher.-
In testimony whereof, I have hereunto set my hand at San Francisco, California, this 25th day of September 191a JAMES COLDON. In presence of- ALFRED Sorno, H. H. ASHLEY.
