Application filedJune 8, 1908. Serial No. 437,373.

To all whom it may concern:

Be it known that I, JEREMIAH HEAGERTY, of Oswego, in the county of Oswego, in the State of New York, have invented new anduseful Improvements in Barrel-Presses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in barrel presses involving the use of a presser head adapted to enter the head of a barrel for pressing the contents thereinto, and suitable actuating means for reciprocating the presser head.

The primary object is to provide a practical and efficient barrel press in which all of the elements are permanently associated and adapted to constitute an article of manufacture capable of supporting the barrel and presser head together with mechanism for operating the presser head into and out of the open head of the barrel for efiectively pressing the contents therein sufliciently to permit the head of the barrel to be easily secured in place preparatory to storage" or shi ment.

ne of the specific objects is to provide means whereby the presser head may be easily released from its pressing position and instantly returned to its normal in operative position. i e

A further object is to support the barrel in the same frame upon which the operating mechanismfor the presserhead is mounted so that the barrels be readily placed in operativerelation to and in registration with the presser head. i

Other objects and uses will be brought out in the following description;

In the drawings Figures 1 and 2 are respectively a top lan and side elevationof a barrel press invo ving the various features of my invention. Fig. 3 is an enlarged side elevation of the upper end of the press similar to that shown in Fig. 2. Fig. 4 is an enlarged sectional-view takenon line 4 4, Fig. 1, showing the reverse view of the parts seen in Fig. 3. Fig. 5 is a sectional view taken on line 5-5, Fig. 3-. I

As shown in the drawings, the barrel as a ismounted in a suitable supporting frame consisting of horizontal base bars 1, opposite upright side bars 2' and a top cross bar 3.

' I preferably provide-a pairof horizontal base bars -l which in this instance con-' sist of round rods spaced apart equi-distant from the verticalaxis of the frame and hav ing their ends secured in suitable angle irons 4 which extend transversely of the rods 1- and are spaced some distance apart to form suitable supporting feet for the main supporting frame adapted to rest upon the floor or other available support.

The upright bars-2 are secured at their lower ends to the angle bars 4 substantially midway between the base bars 1 and extend upwardly some distance above the top of the barrel a where they are secured to the ends and top edge of the upper cross bar 3 by suitable fastening means as screws 5, sufficient clearance being left between the side bars 2 to easily receive the barrel a and permit the operation of a presser head as 6. This presser head may form the head of the barrel or may be firmly secured to a vertically reciprocating rack 7 and adapted to operate'against a separate head for the barrel to press the latter head together with the contents of the barrel downwardly a sufficient distance to permit the head to be secured in place within said barrel.

When the presser head 6 is permanently secured to the reciprocating rack or plunger -7', the lower end of the latter is preferably enlarged horizontally so as to afford a broad bearing for the presser head as shown in the drawings, said presser head consisting in this instance of a bar or plate of substantially the same length as the interior diameter of the upper end of the head or barrel but is somewhat narrower transversely so as to readily enter the upper end of the barrel to press the head into proper place for securement.

The rack or plunger 7 is guided in a suitable frame or bracket 8 having an opening in its top through which the rack or plunger may play and provided with an upright bearing 9-- against which the back of the plunger rides while the opposite upright edge of said rack or plunger is provided with teeth 10 meshing with a rotary pinion 11-, the bearing 9 serving to hold the teeth of the rack- 7in operating enat one side of the cross bar 3- and substantially midway between the upright side bars 2.

The pinion 1 1 and ratchet wheels 12- and 13 are preferably made in one piece of cast or other suitabie metal, the pinion l1 being connected to the ratchet- 12 by reduced portion or hub constituting a drum -15 to wi'iich is secured one end of a chain or cable -16- having its other end passed over suitable idler ---17-- and connected to a spring -18 at one side of and near the bottom of the main supporting frame, the lower end of said spring 18 being fastened to asuitable ichorage -l9 on the lower end of one of side bars -2-. This cable 16- and spring 18 serves as an effective means for returning the rack -7- and pressure head 6 to their normal up positions when the oper ating mechanism hereinafter described is released.

The ratchet wheel 13- constitutes a part of the mechanism for operating the presser head downwardly and for this purpose is engaged by a gravity pawl -20 which is pivoted at 21 to the short arm of a lever 22, the latter being fulcrunied at 23 upon the upper end of the bracket 8. he long arm of the lever 22 extends laterally some distance beyond the vertical plane of one of the side bars 2 and is provided at its outer end with a pondent rod -24- having at its lower end a suitable stirrup -25- to receive the loot oi' the operator whereby the lever in ay be oper ated with a considerable power to force the pressure head 6 downwardly against the head or contents of the barrel to permit the head to be secured in place. This operation of forcing the presser head 6- to its operativeposition is as follows: As the long arm -22 of the lever is depressed by the foot of the operator upon the stirrup 25- or by hand, the pawl 20 which is at the opposite side of the lever 28 is elevated thereby engaging one of the teeth of the ratchet wheel 13- and rotating said wheel together with the ratchet -12- and pinion 11 in the direction indicated by arrow X during which rotation, the rack 7 is depressed or forced downwardly by the pinion 11 and is held in its adjusted position by a gravity pawl 26 engaging one of the teeth of the ratchet -12., This step pawl 26- is pivoted at 27 to the cross bar 3 at one side of the bracket 8 and is provided with a hand piece 28 whereby it may be elevated by hand out of enga ement with the teeth of the ratchet whee -12- to release the ratchet wheels and pinion together with the rack 7 and presser head 6 when it is desired to elevate the latter after the barrel head has been secured in place. During this operation of forcing the presser head (5 downwardly, the chain or cable 16-- is wound upon the drum -15- thereby tensioning the spring -18- and as soon as the ratchet wheels -12- and --]3 and ion -11 are released by throwing the stop pawl. out ol engagement with the teeth of the ratchet wheel l2-, the tension 01' the spring 1S- acting upon the wound cable 16 operates to instantly rotate the ratchet wheels and pinion in the reverse direction thereby elevating or retracting the rack 7- and presser head. -6 to their normal positions.

In order that the presser head may be eii'ectively released to return to its normal up position by the action ol the spring -l8-, it is necessary to disengage the pawl 20* from the ratchet wheel -13 and for this purpose the lower end of said. pawl is provided. with a beveled l'ace -30- which adapted to be brought into engagement with a pin 3 1- on the upper cross bar -3 by simply elevating the long arm 22 ol' the lever by hand thereby depressing the pawl -20 until its inclined face 30 engages c the stop pin 31 which operates to throw the pawl out ol engagement with the teeth 01' the ratchet wheel 13-.

The short arm ol the lever 22- is connected by a spring 32- to a suitable anchorage on the upper cross bar 3 and serves as a means for retracting the lever to its normal position after each compression stroke of the presser head, the pawl 20- being arranged to drop by gravity into engagement with the next succeeding tooth ol the ratchet wheel while the stop pawl 26 drops into engagement with the succeeding tooth ol' the ratchet 12- to hold the presser head in its down position.

The pin 31 may be positioned in such manner as to trip the pawl 2-0- at each restoration of the lever 22 to its normal up position but relying on the stop pawl 28- to hold the rack 7 and presser head 6 in their depressed positions.

In operation, the head of the barrel to be inserted is first placed upon the contents which till the barrel after which the lever -22 is operated to depress the head -(i against the head of the barrel suiiiciently'to enable the head of the barrel to be secured in place, the operating parts being held in their adjusted position by the stop pawl -28-. As soon as the head of the barrel is properly secured, the lever -22- is again operated sutliciently to relieve the strain upon the stop pawl 26- which latter is then withdrawn from engagement with the ratchet wheel 12 whereupon by rocking the lever 22- to engage the pawl -20- with the pin -31, said pawl -20 is disengaged froin the ratchet wheel -13 thereby releasing the ratchet wheel and pinion and also the rack 7 and presser head 6 and permitting the spring to instantly return such parts to their normal position through the medium of the pawl .16.

IVhat I claim is:

1. In a barrel press, a supporting frame for the barrel, a vertically movable rack guided on the frame, a presser head secured to the rack, a pinion engaged with the rack, a ratchet wheel secured to the pinion, a lever and operating pedal therefor, a pawl on the lever for engaging and rotating said ratchet wheel and pinion and thereby depressing the rack and presser head, movable means for holding the rack and presser head in their adjusted position, and additional means including a drum and cable, for returning the rack and presser head to their normal positions when released by the movement of the first named means from its holding position.

2. In a barrel press, a supporting frame for the barrel, a vertically movable presser head, a toothed rack securedto the'presser head, a rotary pinion engaging said rack, means for rotating said pinion, movable means for holding the rack in its adjusted position, a spring connected to the pinion and tensioned by the rotation of the pinion in one direction, said spring operating to return the pinion and rack together with the presser head to their normal positions when the holding means is thrown from its holding position.
