v Applicatiog filed March 30, 1903. Serial No. 150,278.

To all whom it may concern: I

Be it known that I, TREVELYAN SHARP, a subject of the King of Great Britain and Ireland, residing at Manchester, in the county of 5 Lancaster, England, have invented'new and useful lmsprovements in Apparatus for Compressing crap Metal, of which the following is a specification. I

This invention relates to apparatus for compressing scrap metal into blocks or slabs; and its primary object is the reduction of the number of mine necessary in other machines constructed for the like purpose. By these im rovements the general construction of suc apparatus is greatly simplified, while its efficiency is increased.

The improved apparatus consists, essentially, in a cast-iron box having three fixed walls, one reciprocable wall, and a slide-lid. Two rams only are required, as compared with four or five rams in existing app aratusa horizontal ram for compressing the material into a smaller compass by pushing the recip rocable wall forward and a vertical ram'for 1 be hereinafter which motion is given by the hydraulic ram 0. The slide cover or lid dis movable to and fro in the guide-rails d and can be moved in one direction, so as to inclose the box-cavit and in the other direction, so as to complete y uncover it. As shown by the drawings, it asses through a slot in the upper art of the back wall and may be prevented om rising when pressure is applied on the tops of the walls. Its motion can be effected manually or mechanically. The in.-;

- ner face of the wall band of the back wallare so constructed, as shown by Fig. 2, that when the wall I) is pushed into the box to the limit of its travel there is inclosed between the two parts the-rectangular space 6, i "sides of the box, into which the metal is finally compressed. To accomplish thisand metal inwardly in the it being jammed beby internal flanges box, and thus prevent further compressing the material from above. The accompanying drawings illustrate .my

' pression of the diagonal to the tween the ram or movable wall I) and the adjacent walls of the box, the face of the ram 1) is inclined diagonally across the box or press for the greater part of its length, and where it forms an acute angle with the box a reentering lip or shelf is disposed to also direct the scra inward at that edge. The end wall of the ox and two of thefaces of the verticallymoving ram are disposed arallel to the inclined ace of the ram 6. n Fig. 2 a part of the slide-cover dis shown to be broken away, so as to disclose this rectangular space, which is indicated by broken section-lines. Over this part of the box the vertical ram is arranged, the horizontal ram being arranged at the back or outer side of the wall I).

When the apparatus is to be used, the box is fully 0 en and both rams withdrawn. The box is led with the scrap metal and the slide-cover dis pushed over the box into corrtact with the wall 1), against which it is shaped to fit. The hydraulic ram 0 is now put into action and gradually ushes forward and compresses the'mass oi metal, at the same time pushing with it the cover (1, which prevents the rising of the metal. When the ram c has arrived at the limit of its stroke, the

slide-cover is withdrawn from over the space e, into which the whole of the metal has now been compressed and becomes SIJiPPOItBd by the uide-rails of the frame f. he vertical T811115), which has a head of rectangular crosssection adapted to fit into-the s ace e, is now caused to descend and to complete the commetal in that space. The

rams are then withdrawn and the block of compressed metal is removed, after which the operation is repeated with a fresh supply of metal.

The cylinder 9 of the ram h in theconstruction illustrated is carried on the cross-head s, which is supported by four vertical columns. The cylinder 0 of the ram 0 is fixed on a bed which is bolted to the box a at its front end ,and is additionally secured thereto by means of a lug n on the cylinder, a cross-rail m at the back of the lug, and two straps 0 0, bolted to the box a.

Below the box there is a cavity h through which water may be circulated to keep the box cool when in use. may be '5, upon the screw-threaded outer end of the check-rod 11, whose inner end is securedto the ram 0.

The travl of the ram 0 limited by adjustment of screw-nuts To avoid confusion in the. drawings, the

water-service for the hydraulic rams has been omitted, its construction and arran ement being well known and understood. he return strokes of the rams may be made under water-pressure or under the influence of the weights w w, as is also well understood.

Although I have described pressure as being applied to the metal by hydraulic rams, I desire it to be understood that I do not limit myself to this means, since other'means for applying the requisite pressure, such as screws, may be used.

What I do claim as my invention, and desire to secure by Letters Patent, isg 1. An apparatus for com ressing scra metal consisting of a box having three fixe walls, a sliding cover, a movable wall or ram which engages with and moves the sliding cover with it during the compression-stroke of the ram, and a second ram at right angles to the first and .operating to com lete the compression of the scrap, substantia ly as set forth.

2. In apparatus for compressing scrap metal, a box having a sliding cover and three fixed sides, in combination with a ram to compress the scrap under the cover, said ram engaging with the sliding cover and movin it vsn'th it during the compression-stroke, and a second ram moving at right angles to the first to further compress the scrap after the cover has been withdrawn from the box, the faces of the rams and the inner face of the end of the box formin a diagonal chamber in the end of the box, suistantially as described.

3. In an apparatus for compressing scrap metal, the combination of a compression-box having an inclined face at its inner end, a slidin cover, a main ram havin an inclined face a utting against one end of said sliding cover, and a secondary or final ram to complete the compression of the scrap, the faces of the two rams and the inclined face at the inner end of the compression-box forming a diagonal chamber in the end of said box.

4. In apparatus in which scrap metal is compressed in a box by two rams having their axes at ri ht angles, the combination with the box an with the horizontal ram, of a sliding cover which is engaged by'and moves with the horizontal ram durmg the compression-stroke and under which compression is effected.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

TREVELYAN SHARP.
