Aeelne-MACHINE.

SPECIFICATION forming part of Letters Patent No. 467,377', dated January 19, 1892. Application tiled September 12, 1891. Serial No. 405,485. (No model.)

To all whom, it may concern:

Be it known that I, JOS R. MESA, a citizen of the United States, at present residing at St. Catalina, Correl Falso, Macuriges, Cuba, have invented a new and Improved Bagging-Machine, of which the following is a full, clear, and exact description.

The invention relates to machines for filling granulated sugar, grain, the., into bags.

The object of the invention is to provide a new and improved bagging-machine, which is simple and durable in constructiomvery effective and automatic in operation, and arranged to automatically detach the bag when iilled, and firmly pack the contents in the bag.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front view of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. l. Fig. 3 is an enlarged sectional plan view of the same on the line 3 3 of Fig. l. Fig. 4 is an enlarged side elevation of part of the levers and cams. Fig. 5 is an enlarged sectional side elevation of part of the bag-holder, and Fig. 6 is an enlarged plan View of the outer ring or bag holder.

The improved machine is mounted on a suitably-constructed frame A, attached to a post or other suitable support. In the frame A is held atransversely-extending pivot B, on which are fulcrumed the levers C and D, eX-

tending horizontally and in opposite directions, the inner ends C and D of the said levers being curved upwardly, as is plainly illustratedin Figs1and4-,theeXtreme endscarrying friction-rollers C2 and D2, respectively. The friction-rollers O2 and D2 are adapted to be engaged by a cam E, secured on the front end of a shaft E', mounted .to turn in suitable bearingsin the frame A, and carrying a gear-wheel E2 in mesh with a pinion E3, secured on a main driving-shaft F, also journaled in the main frame A, and connected with suitable machinery for imparting a continuous rotary motion to the said shaft, so that the said cam E continually turns around and acts on the friction-rollers O2 and D2 of the levers C and D, to impart a swinging motion to the said levers.

On the free end of each lever C or D is ar4 ranged a bag-holder G, comprising a threaded eyebolt G', supported from an eye on the lever O or D, and engaging with its threaded portion a nut G2, provided with a. series ot downwardly and outwardly extending arms G3, connected with the inside of a ring G", formed with an outer beveled edge extending from the bottom upward and inward, as is plainlyillustrated in Fig. 5.

A ring G5, provided with an inner beveled edge, is adapted to iit upon the outer beveled edge of the ring G4, with the mouth end of the bag between the two rings, as is plainly shown in Fig. 5. In the inner beveled edge of this ring and at diametrically-opposite vpoints are formed grooves G6 to accommodate the seam of the bag when the mouth end of the latter is engaged between the two rings. Partof the mouth is turned over upon the outside of the ring G5, so that when the bag is filled and a downward pull is exerted on the bag the ring G5 is drawn very tight, and consequently the bag is securely held in place on the holder.

The arms G3 are placed a sufficient distance apart near their lower ends to permit of conveniently entering the sugar, grain, or other material or substance to he iilled into the bag. As shown in dotted lines in Fig. l, a spout opens into the mouth end ot the bag to iill the same.

The operation is as follows: Vhen the device is in the position shown'in Fig. l, the re volving cam E in engaging either of the friction-rollers O2 and D2 causes a swinging motion of the respective levers C or D, so that the free or horizontal end of the lever is caused to swing upward, thus raising the bag with the material accumulating in the bag. When the bag is filled, the supply is shut off in any suitable manner, and at that time the long end of the cam passes over the respective friction-roller, so that the latter is released, and the weight of the bag causes a downward swinging of the horizontal portion IOO of the lever, whereby the bag is dropped onto the iioor, and thus the contents are very firmly packed in the bag. NVhen it is desired to disconnect the bag from the holder, the operator takes hold of the outer ring on the downward movement of the bag-holder, so that at the time the bag strikes the oor the ring G4 moves inward into the bag away from the outer ring G5, whereby the mouth end of the bag is disconnected from the two rings. The mouth end readily slips out from between the two rings G4 and G5, so that the mouth of a newly-emptied bag can be readily inserted between the two rings to suspend the emptied bag for filling from the respective levers O or D. The motion of the cam E is so timed in respect to either of the levers C or D and a filling-chute that the bag is filled with the desired amount of sugar, grain, or other material or substance before the respective friction-roller is released, and the lever is free to swing down.

It is understood that the bag is once or any desired number of times lifted and suddenly dropped'before it is completely filled and detached from the holder. Whenever the bag on its sudden downward movement strikes the floor or other suitable fixed supports, the contents of the bag receives a shock, so that the particles closely pack themselves in the bag by concussion. As packing in this manner is continuedv until the bag is filled, it is apparent that the material is thoroughly packed by the time the bag is filled. The bag is then disconnected in the manner above described.

In order to actuate both levers C and D alternately by the single lcam E or to actuate either of the two levers singly, a locking device is provided of the following construction'zA cam I is located directly above the pivot B and is secured' on a shaftJ arranged parallel with' the pivotB and mounted to turn in `suitable bearings in the frame A. The cam I is formed with a semicireular surface I and with two straight surfaces I2 and I3, as is plainly illustrated in Fig. 4. The surfaces of the cam are adapted to engage theinner edges of the curved arms C and D of the levers C andD directly above the pivot B. When the cam I is in the position shown in dotted lines in Fig. l, then the two straight surfaces' I2 and I3 are adjacent to the inner edges of the curvediarms G and D', so that the latter are free to swing inward a sufficient distance to be operated on by the cam E in the manner above described.

.When the operator desires to actuate the lever G only, then the shaft J is turned so that the cam I assumes the position illustrated in Fig. Li-that is, part of the curved surface I presses on the curved arm D of the lever D, thus swinging the said-curved arm outward sufficiently far away from the cam E to prevent the latter from engaging the friction-roller D2. The straight part I3 of thev cam I is adjacent to the inner edge of the arm C', and permits the said arm and lever C to freely swing toward and from the cam E, as above described.

When it is desired to actuate the lever D only, the cam I is turned so that the straight surface I2 is adjacent to the curved arm D', while part of the curved surface I presses 0n the curved arm C', thus throwing the lever C out of engagement with the cam E.

Vhen it is desired to throw both levers C and D out of action, then the camIis turned to the position shown in dotted lines in Fig. AL-that is, until the segmental surface I engages both inner edges of the arms C and Df-thus throwing the friction-rollers C2 and D2 a sufficient distance away from the cam E,

where the latter cannot touch the said friction-rollers. e l

Inorder to conveniently turn thel shaft J, a lever K is fastened to the front end of the said shaft and is formed with a handle end K', in which is arranged a transverse aperture K2, engaged by a pin L heldv on one end of a lever N, mounted tol swing and to turn on the reduced end of the shaft J. (See Fig. 3.) The handle end N". of the lever N is guided in a fork K3, supported on the end of the lever K, opposite the handle end K. The pin L is of sufficient lengt-h to project beyond the rear of the lever to engage one of a series of apertures O, O2, O3, and O4, located equal distances apart and arranged in a circle in a ring O, secured on the frame A and concentric with the shaft J. A spring P presses on the handle end N of the lever N,so as to hold the pin L in position in the lever K and in the respective aperture in the ring O.

When the levers K and N are inthe positions shown in Fig. l, the pin L of the lever N passes through the lever K and engages the aperture O in the ring O, whereby the cam I is held in position to permit the cam E to actuate both levers C and Dalternately. Now when theoperator desires to actuate the lever C only, he takes hold of the handle end of the lever N, presses the same rearward, so that the pin Lis withdrawn from the'aperture-O in the ring O. The operator can then' turn the lever K by taking hold of the handle end K until the opening K2 registers' with the opening O2 and the pin L passes into thesaid IOO IIO

IIS

opening O2 by the operator releasing the pressure on the lever N. The latter is'returned to its position by the action of the' spring P. The turning-lever K turns the shaft J andthe cam I, so that the latter assumes theposition shown in full lines in Fig. t-that is, locks the lever D in an outermost position to'prevent it from being operated on bythe revolving cam E. y y

When it is desired to lock the lever Cin an inactive position, the levers N and K are manipulated in the manner above described, so that the pin L engages the aperture O4 inthe ring O. When it is desired to throw both levers C and D out of action, the position of the levers K and N is changed, so that the pin L engages the opening O3 in the ring O, the cam I then standing in the position shown in dotted lines in Fig.

It is understood that the friction-rollers C2 and D2 do not touch the cam when in their innermost position, as illustrated in Iig. l, the inward swinging motion of the arms C and D of the levers C and D being limited by the cam I, against which the said arms abut on either the straight or curved surfaces I', l2,

or I3.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl.
