SPECIFICATION forming part of Letters Patent No. 560,432, dated May 19, 1896.

' Application filed September 14, 1895. Serial No. 562,533. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES SOHREBLER, of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Bagging-Machines, of which the following is a specification. I

This invention relates to machines for compressing material (preferably wool) into sacks; and it has for its object to provide means whereby the operation may be facilitated and the expense attendant thereon be reduced to the minimum.

To these ends the invention consists in the novel construction and combination of elements which I will now proceed to describe and claim.

Of the drawings accompanying this specification and forminga part of the same, Figure 1 represents a front elevation of an organized machine embodying my improvements. Fig. 2 represents a longitudinal transverse section of the lower portion of the same on an enlarged scale. Fig. 3 represents a vertical sectionalview of my machine. Fig. 4 represents a section on line 4 4, Fig. 2. Figs. 5 and 6 represent detail views hereinafter described.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a frame a, the upper portion of which is provided with cross-beams a a adapted to support guide-boxes a a which boxes receive a rod 1), having upon one side thereof a rack 12, which rack is adapted to mesh with a pinion b secured to a shaft 12 j ournaled in suitable bearings upon the frame a. To the lower end of the rod 1) is secured a packing disk or plunger 0. Said disk with its attached rod is adapted to be moved longitudinally in opposite directions by means of the pinion b meshing with the rack 1) upon the rod 12, said pinion being (as before stated) secured upon a shaft journaled in bearings s s, secured to the frame a, the outer end of said shaft being provided with a gear cl, meshing with a pinion 6 upon a shaft f, journaled in bearings upon the rear side of the frame, Figs. 3 and 4, and having upon its opposite end pulleys g g 9 which are engaged by belts h h, which be rotated in opposite directions, the arrangement being such that the belts are adapted to be alternately shipped onto the pulley g to advance and retract the packing-disk through the connections above described.

The belt h, whichadvances the packingdisk, is controlled entirely by the operator, said belt being engaged by a shipper-fork Z, suitably secured to a shipper rod Z, secured to the frame a and adapted to be operated in opposite directions by a lever m, pivoted at m to the frame and at m to said shipper-rod. The belt h, which operates the means for retracting the packing-disk, is brought into engagement with the pulley g by means of a shipper-rod at, having a fork 02 attached thereto, and an operating-lever n arranged substantially the same as the shipper devices above described, in connection with belt h, and is moved out of engagement with pulley g automatically by the following means: The shipper-rod n has mounted at one end thereof an antifriction-roller o, and the packing-disk c has fastened upon its upper side and projecting upward therefrom a cam-piece 0 (here shown as a piece of strap metal bent to form a leg 0 and an inclined side 0 for coaction with the roller 0, the arrangement being such that as the packer returns to the position shown in Fig. 1 the incline 0 will engage the roller 0, which causes the shipper-lever to transfer the belt h to loose pulley g and bring the packingdisk to a stop.

The advantage of the above-described 5 method of automatically stopping the pack ing-disk at the proper point of its upward movement is that it constitutes a safeguard against the negligence of the operator and also increases the efficiency of the machine,

inasmuch as the operator is enabled to assemble the material for filling the bag while the packing-disk is ascendin It is necessary in the operation of the packing-disk to provide means whereby it can be maintained in position vertically when not in operation. To this end I have provided a gib p, resting in a groove 1), formed in one side of the guide-bearings a 6L5. Said gibis adapted to be held against the side of the rack b by set-screws 19 13 Fig. 5, with sufficient force to cause frictional contact of one side of the rack with said gib and also between the opposite side of the rack and the guidebOX, as shown in Fig. 5.

In the operation of the machine, the packing-disk being in the position shown in Fig. 1, a bag 9' is arranged thereunder, as shown more clearly in Figs. 2 and 3, and said bagis then supplied with material If. The attendant then, through the medium of the lever in and shipper-rod Z, causes the belt h to engage the pulley g and the packing-disk is caused to descend upon the material by the means already described until the material per-rod it, causes thebelt h to be brought into engagement with pulley g, which oper ates the pulley in the opposite direction, causing the packing-disk to be retracted from the bag. The above-described operation of the shipper-rod 01 brings the roller 0 upon the end of said rod into the path of the incline o of the cam-piece 0, so that just before the packing-disk 0 reaches the limit of its upper movement the roll 0 is engaged by the incline and the shipper-rod n is moved to shift the belt h onto the loose pulley 9 which movement arrests the upward movement of the packing-disk, which, through the frictional devices heretofore mentioned, causes the disk to remain normally in this position until the operation just described is repeated. The operator is then at liberty to close the opening of the bag and remove the same from the pit by means of the hoisting-tackle, (shown in Fig. 1,) which, being connected with a sling passing under the bottom of the bag, and by the removal of a doorinthe front of the machine, the bag is readily removed, as will be clearly understood by the drawings.

Having thus explained the nature of my invention and described a Way of constructing and using the same, though withoutattempting to set forth all of the forms in which it may be made or all the modes of its use, what I claim, and desire to secure by Letters Patent, is-

In a bagging-machine, in combination, a

rack-bar, bearings in which said bar is arranged to slide, means, including a spur-gear connected to saidm cans, a plunger connected to said rack-bar, a cam carried by said plunger, and arranged to engage said shipper mechanism to operate the latter, a loose gib mounted in a groove in one of said bearings, and set-screws arranged in said bearing, and adapted to force said gib against said rackbar on a side adjacent to the side occupied by its rack-teeth togrip said bar between said gib and the opposite side of said bearing, with sufiicient force to hold said bar when not operated by said means, without aiit'ectin g the engagement of the teeth of said bar with said ear.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of
