BARREL-PACKING -MACHINE.

Application -fi1ed Mar-ch 13, 1.929.

Phillipsburg, in the county of Varren and State of New Jersey, have invented a new and useful Barrel-Packing Machine, of which the following is a specification.

This invention relates to a new and improved barrel packing machine, for the purpose of packing barrels with fine or granular material, such as cement, and for causing the contents thereof to be thoroughly packed in order that a given quantity or volume of material may be packed in a barrel or the like,-and obviate the necessity of handling the same manually for this purpose, in addition to avoiding destruction of the barrel and constructing the device in a novel, strong and simple manner whereby unnecessary strain or jar is avoided and insuring-ease of operation and durability in use.

A further object of the invention is to provide a mechanicalcement barrel packing machine, by which a series or plurality of barrels can be packed by vertical reciprocation or jar from a. common drive shaft, requiring but low horse power to operate the same, thus permitting the machine to be operated in a'battery of i,6, 9 or other number so that one or more barrels are raised and released at "the same time while the others are operated alternately therewith, so that a given weight of cement or the like, may be packed in a barrel of certain volume and also to obviate manual or skilled labor in the packing of the barrels and in the repair of the machine.

A still further ob ect of the invention is to provide improved means for supporting and holding the barrels and actuating or raislng the same, -to provide improved 'means whereby the material wiil be pre vented from being spilled from the barrel when it is raised and to insure packing thereof when dropped, as well as to prevent the escape of the dust incident to the packing or shaking action; to permit operation of any one or alhor any series or plurality of the devices of a battery, independently or simultaneously, whereby when one device is inoperative-or stationary to permit the removal of one barrel and the replacing new one, the other barrels are being packed, thus saving time, and finally to provide improved :means whereby the Specification ofLetters Patent.

Serial No. 365,570.

means for preventing the spilling of the cement or escape of dust, can be raised out of the way and in direct vertical alinement with the barrel, so as to be readily replaced with but slight exertion and so as not to interfere with the action of remov ing a packed'barrel or replacing a new one to be packed.

\Vith the above andother objects in view which will appear as the description proneeds, the invention resides in the combination and arrangement of;parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirito'f the invention.

In the accompanying drawings:

Figure 1 is a vertical sectional view of the barrel packing machine in accordance with the invention; one of the elements of the series of battery being shown;

Fig. 2 is 'a'plan viewthereof;

Fig. 3 is a detail "bottom view of one of the levers for elevating the barrels by cooperation with its supporting structure;

Fig. 4 is a transverse sectional view taken on the line r4 of Fig. 1, and

5 is a vertical sectional view of a modification.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views, and in the construction and application of my improved barrel packing machine for cement or the like, the numeral 1.0 designates the floor line or floor, beneath which is disposedthe cement or other foundation or base '11 fora base plate 12, which.

is secured or anchored thereto in any manner shown at and which is provided with an upstanding bracket or stand .por tion 14. The anchoring means 13,-may consist of bolts or other securing means em bedded in the base and passed through suitable apertures in the base plate 1201: the stand, the stand proper 14 being cylindrical or othe desired shape, and having a vertical slot 15 at one side remote from the end of the base plate provided with a pair of upstanding bearings 16 in which is pivoted a lever 17, as indicated at 1.8 on a horizontal pivot permitting vertical swinging of the arms of the lever. The arm which extends outwardly from the stand is horizontally disposed and slightly olfset upwardly adjacent to the pivot, said arm bein also longer than the ca dike lifting arm 19 at the other end, which has a reduced portion disposed through the slot 15 and the enlarged end thereof disposed within the stand proper 14: at the center or axis thereof.

h lounted upon the stand proper 14: is a cylinder 20 which is preferably provided with an extension 21 fitting inside of the upper end of the same, the stand having an outstanding or circumscribing flange 22 cooperating with a flange 23 of similar formation at the lower end of the cylinder, whereby the parts may be bolted together or otherwise detachably connected as indicated at 2st. The cylinder projects through an opening in the door 10, as indicated at 25 and receives for vertical reciprocation therein, a plunger 26 which projects from the lower end of the cylinder within the stand ld for contact with the camming end 19 of the lever 17 when the plunger or piston 26 is downwardlydisplaced or at its lower limit, so that the head plate or flange 27 thereof is disposed adjacent to the circumscribing flange 28 at the upper end of the cylind' Of course, the plate or head :2? may contact with the upper end of the cylinder to limit the downward movement of the latter during its vertical reciprocation and to support the plunger or piston if desired. The flange or head plate constituting the head of the piston is provided with an un' cut annular groove 29 adjacent to the peripheral edge thereof and said plateis acapted to receive thereon a barrel or other receptacle 30 adapted to be packed with the cement or other material, while engaged on the open upper end of the barrel is a sheet metal top or rim 31 having an offset en largement 32 at its lower end adapted to rest on the upper edge or ledge of the barrel at the mouth thereof. This top or rim is adapted to accommodate the cement which is to be packed into the barrel. A pad 33 of two or three thicknesses of canvas or muslin is laid on top of the cement under a large weight snugly fitting in the rim or top and bearing down on the pad, so that its a weight rests on the cement, the purpose of the pad being to prevent the cement or dust therefrom, from escaping while the weight remains stationary, that is, it does not work up and down except with the barrel the atter is agitated or reciprocated vertical y, the weight therefore keeping the cement positively in position in the top or rim.

This rim or top which constitutes an extension for the barrel for recelving the surplus material to be packed therein, is provided wi h a plurality of outstanding apertured lugs or ears 35, from which are suspended links or rods 36 connected liitermediately to levers 37 constituting tightening or camming levers which have the inner extremities thereof pivoted likewise to the upper ends of links or rods 38 extending clownwardly and having hooks 39 curved inwardly and upwardly to engage the groove Thus, the levers may be raised to extend the articulated connection constituted by the levers and links or may be swung downwardly to cause the connected ends to be separated in overlapping relation and shorten or tighten the connections whereby the rim or top is held tight on the barrel. it is to be understood that when the levers are raised, the barrels may be placed in position before packing or may be removed after packing, the levers serving to secure the top in position during the packing operation.

In order to impart the necessary oscillating movement to the lever for the purpose of raising the barrel with its contents and at the desired degree, preferably about two inches, the camming arm or enc 19 of the lever 17 is disposed in contact with the projecting lower end of the piston or plunger 26 and supported adjacent to the outer end the long arm of the lever 17 is a drum 40 which is rotatably mounted on a suitably driven shaft ll, it being understood that such shaft may be driven from an electric motor 01' other prime mover and is rotatably mounted in bearings 49 supported upon a cement or other foundation 43, so as to pro ject through an opening in the floor. The drum is provided ith a series removable cams or camming arms 45 which as the drum rotates with its shaft, engage the lever so as to depress the same, thereby raising the arm 19 to elevate the plunger and the barrel supported thereon. As the outer end of the lever is released, the barrel under its weight and load, will drop and strike the cylinder with a hard jar or blow which packs the cement or other material therein, this operation being continued until the proper packing is acquired, it being understood that a speed of 300 reciprocations may be imparted to the piston and the barrel, by the proper speed of rotation to the shaft and the number of cams on the drum, it being understood that this operation is carried on without extraordinary jar or wear on the parts, while the long arm of the lever serves to reduce the amount of force required to raise the load. The cams or arms of the drum may be straight on one side and curved on the other to a proper degree to reduce the friction between the parts, the arms being preferably removable so that they can be readily replaced and bolted in position when worn, for renewal purposes, while the lever 17 is provided with a removable contact portion or end 46 comprising a channel-shaped member straddling the lever as indicated andbolted at a plurality of space points new contact portion, which iii-conjunction with the cams or arms .of the drum, constitute the portions .of the device which are mainly subject to wearexceptthe camming arm 19, which may be constructed in asuitable manner .to compensate for wear, while the plunger .orpi-ston andthe cylinder, may be suitably ground and bushed to insure proper operation thereof, it being understood that parts'subject to wear,maybe suitably lubricated to reduce wearand friction.

In order to hold the device inoperative, there is provided a cam or an eccentric 4:9 pivoted in suitablebearings as indicated at above the floor and operable through a slot '51 therein, .the eccentric being capable of operation through the medium of a throw lever 52, while one of the bearings may constitute a notched segment as indicatedat 53 provided with notches 5% and 55 to 'accom modate the lever 52, and by means of which the eccentric l9 may be held in an adjusted position. Then the lever 52 is engaged 1th the notch 5t,theeccentric wi l be held elevated whereby the lever 17 may be operatedbut when the throw lever is raised to a vertical position .from the horizontal position and is engaged with the notch 54 to engage the latch in the notch 55, the eccentric will l e swung downwardly to depress the adjacent end of the lever whereby the piston will be raised together with the barrels and parts thereon, so that the arms or cams e5 will ,pass the lever without striking the same. By this means, a battery or plurality of the devices -driven from a common shaft, may be independently or simultaneously actuated in any desired arrangement or relation or held inoperative, that is thrown out of op eration, it being understood that the disks or drums 40 are preferably so arranged that a staggered operation or alternate contact of the cams with the. levers is caused, the eby relieving the prime mover of unnecessary load during the operation. That is, if .a batt ry of four of the devices is provided, two may be operated at a time, or successively in alternation and so on with 6, 9 or any number of the devices.

As a means for lowering the weight 34;, and permitting the necessary vertical movement or reciprocation thereof with the barrel, as well as to permit raising of the weights when it is desired to place barrel in position or remove the same, and replace the same withanother barrel to be packed, there is provided in the beams or-other suitable supports 56, a shaft 57 mounted in bearings 58, each device having a large sirable.

drum .59 and a small drum 60. Connected .to the weight as in dicated at :61 and made fast to the smallklrum is a flexible connection .in-a form of a cable or the like .62, while .madefast to the large drum 59 isa cable or the like 63, the cables being wound in opposite directions and so arranged that when one .is wound on its drum, the other is unwound from its respective drum. Thus,

wnenthe weight 34- is engaged in the top or .rim 31, the cable 63 is released :to wind on the drum .59 and the cable 62 is unwound from the drum 60 to lower the wei ht and to permit free reciprocation zthereof vertically. Howeventhe differences in the diameters of the drums is such that a very large leverage is produced whereby a heavy weight :may be raised with a small expenditure of force or manual power so asto wind the cable 62on the drum 60 and unwind the cable 63 from the'drum 59, the cable 63 beingadapted to be connected to a hook or the like 64: atan-adj acent upright or wall, when the weight is lowered and to engage with a projection or hook 65 when the weight is elevated, so as to hold the latter in this position out of the way. The advantage of this device over a lever is that the weight is always maintained directly above the barrel and its rim or top 31 and is therefore in a position to readily enter the same without difliculty, while the arm of a lever would move off center .and require such a large application of force as to render the same objectionable. lVith this device, the weight may be easily and readily elevated clear of the rim to facilitate application and removal of the barrel. Of course, when the throw lever is operated in conjunction with the segment or quadrant '53, the weight is preferably first raised though this is not imperatively necessary, and it will be seen that a single attendant can watch and control the operation of a large battery of the packing devices. It is. also to be understood that the lever 17 and the cylinder as well as the piston or plunger, can be renewed conveniently when found necessary or de- Obviously by the arrangement shown, a considerable saving in horse power for driving the machine is effected and there is also a saving of skilled labor for repairs, there being nothing to wear out except the adjustable arms of the drums or crank shaft, it being understood that such latter device is the mechanical equivalent of the drum and cams and may be so provided, while the adjustable or movable shoes or contact portions 45 may also be readily applied and removed by ordinary labor.

In addition, the device may be made or set to stop automatically when the weight reaches the downward limit of its movement at the top of the barrel, by means of a cable 66 attached to the larger drum 59 at one end and adapted to wind thereon, the opposite end of the cable .or rope being connected to the lever 52 which is employed for actuating the cam or eccentric 49 constituting a part of the throw-out mechanism or means for holding the machine inoperative. The lever has connected thereto, one end of a retractile spring 67 which is suitably anchored at its opposite end and adapted to pull the lever in such a position as to depress the lever 17. The segment 53 is pro vided with a stop 68 designed to limit the throw of the lever 52 and owing to the length of this lever, the tension .of the spring need not be very great in order to pull the lever, assisted by the overhanging of the portion of the cam which is the part i of the greatest eccentricity. Thus, it will be seen that when the barrel is packed, the cable will be released, the spring then acting to depress the lever 17 through the medium of the eccentric or cam. That is, when the barrel is packed and the weight has gone down in the barrel, the cable subsequently comes up and engages in the latch on the quadrant so as to release the lever and allow the spring to pull the same against the stop, thus stopping the machine. I desire to have it understood that the piston is preferably provided with a stroke of about two inches so that the barrel and weight may be correspondingly raised and allowed to drop with a hard jar against the cylinder, so as to thoroughly pack the barrel. In addition, the device serves to save material or stavcs, as about one-quarter less material or a barrel about one-quarter size smaller may be used to contain a given volume or weight of cement, than ordinarily where a screw or other type of packer is used.

In the operation of the device the barrel is placed in position and the rim clamped thereon, the material being also placed in the rim to a point near the topthereor". The perils laid over the cement and the weight lowered or let down on the pad and cement to remain stationary during the reciprocation of the plunger and barrel. As the shaft is operated to rotate the drum, the lever is oscillated to reciprocate the plunger or piston and the barrel, the weight moving therewith l'iut remaining stationary with respect to its iOSllClOIl relative to the barrel except to its movement downwardly as the latter is packed in the barrel. The continued reciprocation of the barrel packs the material therein, the weight serving to keep the dust from arising therefrom, from escaping, in connection with the pad and preventing the cement from being precipitated or thrown from the arrel and the creating of dust, at least to an excessive degree. This operation is continued until the barrel is packed,

thus expediting the packing of a large num ber of barrels. In Fig. 20f the drawings I have shown two of the devices connected in battery formation, but it is to be understood that the number may be increased or varied as desired- In the form of the invention shown in Fig. 5 of the drawings, thecylinder 69 is provided with a flange 7O bolted or otherwise anchored as shown in 71 to the concrete base or foundation 72,- said anchoring means consisting of headed bolts or the like suitably embedded in the base and projecting-above the same for detachable connection of the cylinder flange thereto. It is of course, to be understood that any number of cylinders may be provided, and each cylinder is formed to extend below the flange as indicated at 73, the foundation being open beneath to form a tunnel as shown at 74: for supporting therein at the bottom, a bearing 75 for the shaft 7 6 carrying the drum 77 provided as heretofore described with the removable cams or camming arms 78 for direct engagement with the lower ends 01" the plungers or pistons 79 in order that the piston may be raised and lowered or permitted to drop to shake or agitate the cement or other material in the barrels or other receptacles mounted there on, Ior thoroughly packing the cement. The other parts are the same as described in connection with the first form and since the operation of the device has been clearly set forth, further description is deemed unnecessary. However, it may be stated that this form of the invention is for the purpose of saving space or allowing the installation of the machine in less space than the machine shown in the first form and employing the lever 17 although in the former case, less horse power is required to operate the machine.
