l Claim. "(creme- 100 This invention relates to a device into which aquantity of ferrous, non-ferrous. andr'similar organic wastes, or similar articles are deposited, the device including means defining a ipressyfor "exerting temporary ,or permanent pressure upon the waste" material, :thus to impart a squeezing action to same, for the purpose of causing oil or similiar cutting liquid that normally coats the waste material to be drained off or forced out of the bottom of the container 'in which the waste material isdisposed, for future use or for disposal thereofotherwise.

Inmachine shops or likeestablishments, metal cuttings and otherrmetal waste accumulate,these constituting waste produced when-various workpieces are being ground, forged, or otherwiseformed. Cuttings of this type are coated with oil,.and it is desirablethat'the oil be drained off or forced outzof :thesame for reuse, for salvage or for other purposes. :Alternatively, it is, desirable to separate the oil from the metal cuttings in view of the fact that salvaging the cuttings" themselvesmay involve, in some instances, operations inwhich the amount of oil confined in a mass of cuttings should be kept to a desirable minimum. Still further; a device of .the character described has value' in that metal cuttings ,-which may be in the form of curls, elongated strips, andthe like occupy a consider- 1 able amount of==space.:-:It .is desirable,therefore, if the cuttingsarertobersalvagedythat they be compressed into the smallest possible; area; to facilitate theirtransportation'and to facilitate,- also,-:their being re-melted. or otherwise handledfortthelpurposerof permitting reuse of the metal contained therein.

An important object ofthe present invention, in view of the above, is to provide a device ofzthecharacter stated a that willbe so designed as tocbe capable of manufacture at low cost, while stillcbeingadapted to effect squeezing .or. compressingof'asubstantial quantityiof cuttings, forg- 'ings, waste strips of; metal, .etc.

. Another object" is .toprovide adevice of the character stated that will be capable": of: manufacture at low cost,

' will occupy a' comparatively smallamountofspace, and i will be r'eadily portable",=.soas 'to'be used atany location within the machine shop or -:other establishment.

Still anotherobjectiof importance is to provide a device of the characteri stated-that will be capable of manual For further comprehension of the invention, andof the objects andQadvantagesthereof, reference will be had to the followingdescription and. accompanying drawings,

Fig. l 17 is a view similar to Fig. 5 of still another modified form of carriage, a container being shown-in dash lines.

'Fig. 18 is aside elevational view of the modified form of carriage shown inFig. 17 with a container shownsupported thereon in dash lines.

Fig. 19 is a side elevational view of yet another modiified form of carriage, with fragment of a containerv shown .thereon in supported position.

Referring to the drawings in ,detail, the device includes a cylindrical, upwardly opening container 10, the bottom of which is formed with one or more drain openings .12 for oil separated from a quantity of waste metal cuttings W pressed within the container. The container is rollably supported on a carriage generally designated 14,

having a generally semicircular side wall 16, the diameter of which is slightly greater than that of container10.

- Connected between the ends of wall 16 is a crossbar 18,

- and as shown in Fig. 5, fixedly connected between cross- .bar 18 and the midlength portion of side wall 16 is a brace bar 20.

A pair of rollers 22 is provided, these being disposed adjacent the ends of bar 18 and being carried by yokes of in- .verted U-shape ,fixedly secured to the crossbar 18. A

swiveled roller or caster 24 is attached to the rear end of brace bar ltl, tofacilitate steering of the carriage.

Fixedly connected between bar 18 and wall 16 are guides .26, supporting a removable pan 28 having outwardly ":"tume'd supportflanges'30 along itsopposite sides, The

as at 32 (see Fig. whereby the oil flows to the center U thereby avoiding spilling over the sidewall to the floor.

Referring now to the press mounted in the upper end of the container, this includes a clamp 34 formed with a support bar 36 from which project bridging elements 38 of inverted J-shape. Threaded, transverse openings in the ends of bar 36 receive clamp screws 40, the inner ends of which engage against the side wall of container for clamping of the side wall between the inner ends of bridging elements or arms 38 and the clamp screws and hold the clamp on the container.

On the outer ends of the clamp screws, heads 42 are fixedly secured, having diametrically extending openings in which slide handles 44.

A flat presser plate 46 fits loosely within the upper end of the container 10, and overlying the plate is a cruciform support member 48 bolted at 50 to the marginal portion of plate 46, and also riveted or bolted at 52 to the center portion of plate 46.

On the outer end of one of the arms of support plate 48 is a sleeve 54, disposed between members 38. On the opposite ends of the same arm a handle 56 of angular formation is fixedly secured, and extends outwardly of the container. A hinge pin 58 extends through the sleeve, and is engaged at its ends in openings formed in the members 38.

Thus, after a quantity of waste is deposited in container 10, with the lid swung upwardly, the lid may be swung back to its closed position, and will press the waste downwardly within the container. Each time the waste is compressed, an additional quantity of waste is deposited in the container, and is compressed by downward swinging of the presser plate 46. The operation is continued until such time as the waste is fully compressed. Oil will accordingly drain through the opening 12, and the waste is thus compressed while at the same time being separated from the oil or other liquids coating the same.

If desired, the hinge axis of the presser plate can be adjusted circumferentially of the container, by loosening the screws 40, thus permitting the clamp to be shifted along the circumference of the container, to relocate the hinge axis of the presser plate.

In Fig. 6, a modified oil pan is shown, which is similar in all respects to the pan of the first form, except for having an approximately triangular, freely perforated strainer plate 60 in one corner. The purpose of this arrangement is to permit the oil to be poured out of the pan, through the strainer, without causing any cuttings or metal particles that may have been forced through opening 12 to also flow from the pan.

In Fig. 7, another modified pan 28 is shown, having a rolled side flange 30 along each of its sides. In this form, the pan slides in confronting channels 26 secured to the carriage in the same manner and at the same location as the guides 26.

In Fig. 8, the container 10 is identical to that of the first form. In this form the modification resides in the clamp, which has been designated at 34*. The clamp 34 shown also in Fig. 9, includes an arcuate support bar 36 in the ends of which threaded openings are formed, receiving clamping screws 40- having knurled heads 42*. The screws extend radially of the container, and projecting forwardly from the bar 36 are bridging elements 3S hingedly connected to the support member 48 in the same manner as the arms 38.

This form of clamp may also be freely adjusted in a circumferential direction about the container.

In Fig. 10, another modified clamp is shown, designated generally at 34. This clamp includes a support aseasav bar 36', from which arms 38 project forwardly, for hinged connection to the presser means.

This form of clamp does not require the use of screws, and instead there are provided detents 40, adapted to snap into place (see Fig. 11) under the circumferential head 64 provided upon the upper end of the container.

The detents or plungers 4t) slide in square openings, to hold the detents against rotation. Referring to Fig. 11, the undersides of the detents, where they project forwardly from the bar 36*, are sloped to provide cam surfaces 62".

On the inner ends of the plungers, circular collars 66 are formed, limiting forward movement of the plungers. Projecting rearwardly from and integral with the collars are shanks 68 sliding in openings formed in an upwardly projecting flange 70 formed upon the rear surface of bar 36 Rearwardly of the flange the shanks are integrally formed with heads 72*, to permit manual retraction of the detents against the restraint of springs 74 that are held under compression between the flange and the collars 66 It will be seen that the springs normally urge the detents to the Fig. 11 positions thereof. When the detents are in this position, they engage under the bead of the container as shown in Fig. 11, to hold the clamp in position upon the container while still permitting free adjustment of the clamp and the presser means rotatably upon the upper end of the container.

If, however, it is desired to remove the clamp and presser means, it is merely necessary that the detents be retracted manually into the bar 36, after which the clamps can be lifted off the container side wall.

To apply the clamps, one merely presses the same downwardly upon the upper end of the container side wall, so that the cam surfaces 62 engage the top surface of the bead of the container. This causes the cams to effect retraction of the plungers, against the force of the springs, causing the clamps to move into position straddling and engaging the head 64 of the container.

Various other types of detents, snaps, or the like might be employed for holding the clamps in position upon the side wall of the container.

Referring now to Figs. 12 and 13, in this form of the invention the clamp 34 is used, although the clamp 34"- or 34 might be employed to equal advantage. The modification shown in these figures of the drawing relates to the presser means. As shown, there is provided a circular, flat presser plate 46, and overlying the same is a wide, flat, approximately rectangular member 48 fixedly secured to the presser plate by bolts 50. The presser plate is detachably connected to the support member, and as a result, one can attach a plurality of the presser plates, in superposed relation, to the underside of the support member. This weights the presser means, so as to facilitate compression of the waste material within the container.

The support member 48at one end has a tongue terminating in sleeve 54 receiving the hinge pin. At the end of the support member opposite the tongue, a handle 56, formed similarly to the handle 56, is fixedly attached.

In Figs. 14 and 15, the container 10 and carriage 14 are identical to those of the first form. The presser means, however, is modified to include a vertically disposed screw, which is threadedly engaged in an upwardly projecting boss 76 centrally and integrallyformed on a fiat, circular support member 48 having diametrically opposed tongues 54 formed with hinge sleeves receiving hinge pins carried by diametrically opposed clamps 34.

The support member is thus fixedly secured within the upper end of the container, and threadedly engaged in the boss is the screw previously mentioned, designated at 78 Fixedly attached to the upper end of the screw is a hand wheel 56*, while at the lower end of the screw there is a reduced axial extension 80 passing through a. smooth-walled opening centrally formed in a flat, circular presser plate 46 A nut 82 is threaded on extenplate 46 and a jam extension to lock the sion 80 against the underside of nut 83 is then threaded on the first nut in position.

The nuts are not turned tight against the plate 46 the purpose of this being to permit the presser plate to remain stationary despite the rotatable movement of the screw during the raising and lowering of the presser plate. When the presser plate engages against the waste, it tends to remain stationary, and thereafter downward movement of the presser plate occurs without rotation of the same with the screw.

The construction shown in Figs. 14 and 15 permits any number of presser plates to be secured to the screw, within limits determined by the length of the extension 80 Thus, the presser means can be adjustably weighted or strengthened as desired.

In use of this form of the device, one of the clamps may be detached, from the container. Thereafter, the presser means can be swung upwardly about the hinge axis of the other clamp. The waste is then deposited Within the container, and on rotation of the screw with both clamps fixedly engaged with the container, the waste will be compressed. The screw can, of course, be of any desired length, and this will permit the full amount of the waste to be compressed in a single operation of lowering the presser plate.

Referring particularly to Fig. 16, in this modified form of the invention, the carriage 14 is omitted and the rollers or casters 22 and 24 are removably attached to a flange 90 depending from the bottom end of the container or barrel 10. Attachment is made by swivelly connecting the yokes mounting the rollers to U-shaped clamps 34 and by clamping the clamps to the flanges, by clamp screws 40 passing through one leg of the clamps.

A modified presser means is also provided in the form of a deep dish cover or lid 46 The act of placing the cover or lid in protective position over the top of the barrel 10 compresses the material within the container.

In the modified form of carriage 14' shown in Fig. 17, the semi-circular side wall 16 is replaced by upstanding flanges 92, 92 on the ends of the plate 18 and a similar upstanding flange 94 on the free end of the brace bar 20'. The container 10 is held on the carriage 14' by a front chain 98 supported by and between the flanges 92, 92 and by side chains 100 supported by and between flanges 92, 92 and 94. A container or barrel 10 with removable pan 28 is shown in dotted lines supported on the carriage 14 in Fig. 18.

The modified form of carriage shown in Fig. 19 differs from the form of carriage shown in Fig. 17 in that the semi-circular wall 16 is retained and the flanges 96, 96 on the ends of the plate 18" and on the free end of the brace bar (not shown) depend downwardly instead of being upright. In this form, the rollers or casters 22" and 24" are fastened to the flanges in a manner similar to the fastening of the rollers 22c and Me to the container or barrel 10 in Fig. 16 by means of U-shaped clamps 34" and clamp screws 40".

It will be understood that the various modified features can be interchangeably employed, that is, any clamp illustrated and described can be used with any of the various presser means shown. Then again, any of the pans can be employed, as desired, thus increasing measurably the versatility of the device when the same is in use.

The device has the further advantage that it is fully portable, occupies a comparatively small amount of space, and is adapted for one-man operation without the requirement of expensive and complicated means for supplying pressure, such as hydraulic pumps, air compressors, and like devices.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

Apparatus for compressing waste material and the like, comprising a carriage, an upwardly opening waste container removably supported by the carriage, presser means within the upper end of the container adapted for compressing waste within the container, the container having at least one drain opening at its lower end, a pan removably supported by the carriage in position below the drain opening to receive drippings flowing through the drain opening responsive to compression of said waste, said carriage including a generally semicircular side wall, a crossbar connected between the lower ends of the side wall, a brace bar connected between the crossbar and the midlength portion of the side wall, and roller means carried by said bars, said roller means including a pair of rollers at opposite ends of the crossbar rotating on axes parallel to the length of the crossbar, and a third roller swiveled on the brace bar to facilitate steering of the carriage, said brace bar having a downwardly offset midlength portion to space the brace bar downwardly from the drain opening, whereby to permit flowing of the drippings into the pan, the carriage including a pair of guides fixedly connected between the crossbar and the side wall at opposite sides of and in parallel relation to the brace bar, below the crossbar, said pan being slidably supported by the guides, said pan being formed with outwardly directed flanges at opposite sides thereof supported upon the guides.
