6 Clailnsr (Cl. 100 -57) 'The' inventionrelates to a press for removing curl from smoked skinnedfbellies.

An object of the present invention is to provi'de a simple, inexpensive and efiicient belly press of strong and durable construction, adapted to flatten and remove the curl from smoked skinned bellies and "capable of enabling the product'to be placed in and removed from, it without touching the meat with the hands, thereby eliminating one source of contamination heretofore present in means. employed for straightening or flattening slabs of, bacon for removing curltherefrom. a

A further object of the invention is to' provide a belly press of this character with which it will not be necessary to'leave the bacon in the clamping or pressure applying means more than one hour and which will permit the slabs of bacon wlien the pressure is removed to be hung back on the trees. or spread apart and permitted to remain on suspending means of the belly press to; prevent the bellies from sweating.

Withthese and other objects in view, the invention. consists in the construction and novel arrangement of the parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims. hereto appended, it beingunderstood that various changes in the form, proportionland minorsdetails of construetion, within the scope of the claims, may be resorted to without departing from the, spirit or sacriflcin bn o pthe advantages of the invention. r In the drawings:-@ t Figure l is a perspective view of'a belly press constructed in accordance with this invention. Fig. 2 is a front elevation of the same illustrating the manner of pressing the smoked skinned bellies.

Figs. 10, 11 and 12 are detail views illustrating the manner of slidably interlocking the horizontalguide bars of the press with the ends of the same. j p

In the accompanying drawings in which is illustrated the preferred embodiment of the invention the belly press comprises in its construction a rigid frame suspended from an overhead supporting rail 1 by means of end and intermediate hanger bars 2 and 3 and provided with a lower body portion composed of substanr tially oblong end members 4 and upper and lower pairs of horizontal guide bars 5 and 6. The end members! which are connected by a lower centrally arranged horizontal suspension rail '7 are composed of spaced vertical side bars 8 and top, bottom and intermediate horizontal connecting bars 9, 10 and 11 disposed transversely of the ends of the body portion of the frame of the belly press and preferably formed integral with the vertical bars 8, as clearly illustrated in Fig. 1 of the drawings.

The upper and lower horizontal guide bars 5 and'6 which extend longitudinally of the body portion of the frame of the belly press at the top and bottom of the said body portion are spacedlaterally to receive between them fixed vertical press plates 12 and slidably vertically disposed press plates 13 and they consist preferably of angle bars having vertical and horizontal webs or'flanges which are slidably interlocked with vertical and horizontal slots or branches 14 and 15 of recesses 16 formedin the ends of the top and bottom bars 9 and 10 of the ends of the press frame. The vertical flanges of the horizontal guide bars extend upwardly from the angle of the bars and the horizontal webs or flanges of the angle bars extend inwardly from the vertical webs or flanges to form guides for the press plates 13 and also to confine the slabs 1'7 of bacon and bacon separating and flattening plates 18 within the frame of the press.

The slidable interlocking of the guide bars 5 and 6 with the ends of the frame enable the said bars tobe readily removed when desired.

The fixedvertical press plates 12 which are located at one end of the frame may be welded or otherwise connected with the adjacent end 4 of the frame of the press and they extend above and below the horizontal guide bars 5 and 6. The slidable press plates 13 which are supported and guided by the horizontal flanges of the guide bars 5 and 6 are provided at their side edges with laterally projecting lugs 19 which are spaced apart to form intervening recesses or slots 20 to receive the horizontal flanges of the guide bars, as clearly illustrated in Fig. 6 of the drawings. The slabs of bacon which are provided with suitable hangers 21 are hung in the press from the lower horizontal suspension bar 7 and also from an upper horizontal suspension bar 22 located above the body portion of the press and formed integral with or otherwise rigidly conflatten the slabs of bacon and remove the curl, therefrom when pressure is applied to the slidable press plates 13 by means of screws 24.

The screws 24 which are disposed longitudinally of the body portion of theframe of the press at the top and bottom thereof and at one end of the same are mounted in suitable thread ed openings 25 in the bars Qand 10 of such end of the frame and the said screws are provided at their inner ends with circular or semisspherical heads 26 which are arranged in suitable bearings or sockets 27 located at the centers of the slidable press plates 13 and preferably formed by enlargements at the outer faces of the press plates 13. The outer ends of the screws are provided with suitable operating means for enabling the screws to be manually rotated for applying pressure to the slabs of bacon. The operating means may consist of bars 28 preferably tapered and wedged in suitable slots or openings in the outer end portions 29 of the screws and extending laterally from opposite sides of the screws to form lever arms. Any other suitable means may, of course, be provided. When the screws are rotated the press plates 13 are forced inwardly and pressure is applied to the slabs of bacon and curl is removed. therefrom. A slab may be subjected to pressure for any desired length of time, but it has been found by practice that one hour is sufficient for removing the curl from bacon.

The hanger bars 2 and 3 are provided at their upper ends with hooks 30 and 31 for engaging the supporting rail and the intermediate hanger bars 3 have offset upper and lower portions which are connected by substantially U-shaped portions 32 extending laterally from the upper suspension rail 22 and also spacing the upper portions of the intermediate hanger bars from the said rail 22, as clearly illustrated in Figs; 1 and 5 of the drawings. V

This provides clearance for thehangers of'th'e slabs of bacon and the bacon separating and flattening plates 18. The lower ends ofthe oifset lower portions of .the intermediate hanger bars are connected with the lower suspension rails 7 by means of arms 33 which are secured to the lower suspension rail 7 at the lower edge thereof so as not to interfere with'thefsliding of the hangers of the slabs of bacon and the plates 18 along the said horizontal suspension rail 7.

The various parts of the press are designed to be constructed of galvanized metal and the hanging of the press from the overhead supporting rail will enable the press to be removed bodily therefrom and also to be moved along the supporting rail for transferring the press and its contents bodily from one point or place to another and also removing the press for cleaning or other purposes. Also the suspension of the bacon from the horizontal rails 7 and 22 will enable the product to be handled separately from the press after being subjected to pressure.

What is claimedis:
