SF ECIFICATiON forming part of Letters Patent No. 538,013, dated April 23, 1 89 5.

' -:Application filed December 10, 1 94. Serial No. 1,311- (N m To all whom it may concern.-

I Be it known that we, CHARLES A. CUsHMAu and JAMES F. GUTHRIE, of Somerville, county State-of Massachusetts, have invented an Improvement in Packing-Presses,

of which the following description, in'con nection with the accompanying drawings, is a.

. cles are packed operation,

- tion' of a simple, compact and rapidly operspecification, like letters and figures on the drawings representing like parts.

When bacon, hams and other similar artiinto boxes, it is desirable to pack the boxes or cases as tightly as possible, not-only to thoroughly fill them, but to also during transportation.

prevent movement or shiftingof the contents In packing-houses, presses have beenv employed for this purpose, the be): or case. with its con tents, being placed under the plunger of the press with the box cover between the contents and the face of the'plunger, is applied to the latter to force the lid or cover into place, compressing the contents by such and the cover'is' nailed or otherwise secured in place before the pressure is removed. So far as we are aware,the presses used-for this purpose are cumbersome, requiring the combinedstrength of several men to operate them, and, in practice, it takes considerable time to pack each box or case.

This invention-has for its object the producated power-press, the press being mounted upon asuitaole track so that it can be quickly moved from one pointto another, thus ob: viating considerable handling of the packing cases, the application ot-motive power to the press, automatically acting. to hold it stationary and rigid against the fixed abutment.

In accordance therewith our invention consists in details of construction, arrangement and operation hereinafter fully described and particularly pointed out in the claim.

Figure 1, in end-elevation, represents a A press embodying our invention, the plungerrod being broken off to 'a longitudinal section and Fig. 3, is a save space. Fig 2, is on the line at, Fig. 1; sectional detailon the line We have hereinshown the press as composed of a strong cylinder at having heads a and power plunger rod as rotatably a, suitably flanged and connected with the flanged ends of the cylinders by bolts 10, ill

. usual manner.

The head a is made-as a solid block and cylindrical at its outer end to receive thereon a cap I) chambered out at b to receive easily therein the cylindrical end of the head a, the

wise supported, if desired, said beams, however, being adapted to form a rigid abutment for the upper end of the press when in use.

The cylinder head a has a plunger-opening therein, and alsofa suitable stufiing box et -and downwardly extended guides a terminating in a bearing a some distance below the head to guide the plunger-rod a when extended. The said plunger-rod has secured thereto a suitable piston e, movable in the cylinder, and we haveshown the outer extremity of the lar groove 6 and co-operating, plate c to a bearing block 6 secured by suitable bolts, as 5, to a plunger e whereby the latter is rotatable about the plunger-rod.

We have secured to the cylinder herein shown, as'by bolts 15, a valve-boxf, having a four-way valve f therein of usual construc-' tion, and as shown in Figs. 1 and 3, the valvebox has an inlet gand an outlet and pipes h and Mopening respectively into the cylinder at its opposite ends and on opposite sides of the piston e.

As shown in Fig. .2, the plunger is retracted, and the apparatus is in position to pack a box when broughtbeneath the plunger c and the valve f as shown in Fig.6, is turned to connect the inlet 9 with the pipe h leading to the upper end of the cylinder, the on lot or ex haust g being connected with t e pipe 7t forming the cylinder exhaust. If now steam, compressed air, or water under. pressure is adsecured by an annumitted to the cylinder through the pipe 7:, the

and asthepressnre of the fluid incneasesflhe' contents of the box or compressed therein, and the cover on the box case will be powerfully can be nailed in place before removed.

It will be noticed by an examination '2, that normally the weight of supported by the truck-wheels, e the rails (l, the cap I) being below the under surface of the beams A. The pressure of the fluid upon'the top of the piston e will ioroo it downward until the plunger meets the box cover and further movement is resisted by the contents of the box or case, end the 'gpresern'e of the fluid on the cylinder head a Willthen tend'to lift the cylinder and its attached parts until the cap I) is brought firmly a'gainst'the under side of the beams A, further pressure compressing the air in the space I), and, cnnhthe pressure is of Fig. the press is ioning thereby the apparatus, The e flinie sion of more fluid alcove the piston will then force the plunger downward, the heanisA. act'- ing as a fixed abutment for the apparatus until the contents of the box or case have been sufficiently secured in place. As soon the cover has been secured,the valve f is turned bymechanisin to be described, to connect the pipes It and g and pipes g and it", so that the fluid above the piston will be exhausted through the outlet 9', andwill be sdinii'ted beneath the piston through the pipe h to raise it into normal position, and as soon this takes place, the press will settle down by its'vreight until the wheels c again rest upon the tracks (1, it being understood that when the appamine is raised as has been described, the wheels will be raised from the traclte and will remain out of contact therewith throughout the operation of pressing.

A valve. stem f is extended outwardly through the valve box, and has fast thereon an arm f, which is pivotnlliy connected by links f and f with handle e pivoted at f to a boss of on one of t e resting trigoncompressed to enable the cover to he" Vere f n-nil The hearingnli'or the JhiHgBIE' I'Od e'is out ,Fig. 2, to receive therein a hearing blooka" held 'in adj ustcd away at one side, as at a parts of the pa'ckinganother point as it; may: he; needed, so that onemen can operate'the prese'with the greatest ease.

The press is very rapid and efiicient inoperetion, and steam, mien-or compressed, air may he usedns the motive fluid-as desired or ts most convenient, neeted with the source of supply byLflexi'ble tubing, and by similar means. the exhaust may be cerried to any desired point.

it will be obvious that the press may beused in any case where itr-is desired to compress any substance into smaller space, whether confined in a case or box or not, for it will be evident that baled products may be compressed preparatory to being handed or otherwise held in compressed condition.

We clainm- In a compressing or packing press, shylincler having a port at each end, a piston rcciprocablo therein, and rod end plunger, combined with a controlling valve for said ports, an internally recessed cap on and into which-the closed end of the cylinder, tightly enters as a piston to i'orm an air cushion .when moved against a fixed abut-- ment, and menus to portshly-cnepend said cylinder, substantially as described. 1
