Application December 14.,-1933, sena1Nt5702g2s2 8 Claims}: o1 .3r ;3 1 fj This invention pertains to work tables or benches provided with tiltable tops, and especially for use in food processing, particularly-in the meatprocessing industry. g An object of the invention is "to furnish a work table, preferably of metal, having a tiltable top and constructed and arrangedto withstand very heavy use, and'every portion of which may be readily and thoroughly cleaned, Anotherobject is to furnish a work table with a 'tiltable'top portion thoroughly braced throughout and fully supported along its longestedges so as 'to 1 withstand heavy weights, that" may be imposed'thereon. 4 j

' Still another object is to provide a work'table with a tiltable top reversible for'easy and thor-' ough renovation, and to include a supporting member along both of its longitudinal edges one of which members ismovablewhereby to release said top in order that it=may e swung freely upon its supports fl v Besides these objects theinvention includes various structural advantages as will appear herein aided by the appended drawings [where'- "Figure 1 shows a table in perspective constructed according to our invention. Figure 2 is asectional view taken-on line 2-2 of Fig.

. 4; Figure 3 shows in perspective the underside of the table top-showing certain-bracing structures. Figura is a front elevation of atable of slightly different proportions from that shown in the earlier figures-andproduoed on a 'smaller scale than Figure 2. Figure 5 illustrates in-pe'ra the framing of the table and part of the table-top, and Figure 6 is a transverse 'seotion,"in elevation, of a portion of-Qthe table parts produced online 6 --'6 of Figure 4. In institution's commonlyreferred to 'as pack- 40 ing houses-,'where meats are processed, it has I been customary to provide woodentables "or benches on'which to cut ahd'otherwisetrea't' the meats. Owing to the fact that besides being made of wood and difficult "to cl'eangthe'tabletop upon which the work is done is a fixed'mem ber requiring, in "an attempt to maintain as nearly as possible a sanitary condition, that the attendant must not only scrape, wire-brush and wash all surfaces with water butmust also clea'n 50 the under surface'of the top me'mber bywork ing beneath the 'latter in order to be 'sureof some semblance of the cleanliness 'req uired by government sanitation inspectors. Quite naturally, it is almost if not entirely impossible to maintain a thoroughly sanitary condition of a table having a fixed top and especially if it be of wood, and in view of this we have devised a table of the type to be described.

In the figures of the drawings a framing is provided of angle iron, for example, there bepreier'ably of a type resistant" to corrosion, from one gof wh'o'se' sides at each end thereof, and at *a'ndjpermit tilting thereofas shown in the first to say, betwee comparatively light 1 weight.

'Q'Ihe two (and members thus provided are connected by a rear top member 3', again as by welding, and are connected at the front by a'membere attached at its ends to theiront legs2 somedistancebelow the level of said top members 1;1, about as shown, there being a 'centrabsupporting 'leg 5, by preteie'rrce for said member "4. A top member 6 oisheet'metal is'next provided, which is *the'iniddle of -its width, extends an arm 'lp'ro bolt Figure 2, "to extenjd through an end 'm'em be'r 1, serving to" pivotally support the" said top "two figures. This top firwh'ich may have"greater or less lengthy depending' upon the {particular purpose for which it'fi's" to be used, is relatively thin, s'ay'one-eighth teens-quarter of an inch,

"in orden'to "obtain comparatively lightweight and to hold down the cost, and thereforea strengthening and stiffening structure is provided somewhat as shown inFigure 3. That is the mentioned arms "-7 are spaced arms 10, all of the arms carrying arod- 1 1to which, are welded the spaced apart "arms-:12, and-finally a truss-rod 13 extends over'jthe ends of the last *named=arms and is welded- "at" its ends to the rod 11 in about the" position shown. This; as may be seen, provides an exceedingly strong and rigidwork-supportin'g 'structure'o f However, any equivalent arrangementmay be'used that-will serve the purpose; a The top "*6 when in its work supporting position top terrace "of the latter, if desiredybein'g' made. to; lie .below'the top surfaces of the end-member's.

Extending between and-mounted inthe extremities of thestwo'lever-arms is-Ia 'rod :17 .held inthe position s'hown in-Figure 2 by a at 19 on:one" ofthe;legs and engaged over-Ha part of an adjacent lever-arm, the latter having a convenient handle-portion 19 for operating the structure. Affixed to the rod 17 is a supporting arm or prop 20 which, as shown in 1 latch, 18pivoted -1 15 Figure 4, rests upon the member 4 just above the leg 5.

As particularly shown in Figure 4 the structure just described supports the front edge of the top 6 throughout its entire length, as does the member 3 at the rear edge, which is most important, and one of the objects of the invention, since extremely heavy weights are often carried by the said top, it being clear that the

truss arrangement

11, 12, 13 together with the supports for the said edges of the top provide-a heavy duty type of table.

In Figure 2 the rod 17 is shown in dotted lines in a lowered position and out of the path of travel of the front edge of the top so that the latter may be swung freely to any position, see also Figure 1. When the latch 18 is lifted to release the lever-arm 14 the rod 17 can be moved downwardly to a position where the top 6 will pass it at such times as cleaning and renovation of the table is to take place, it being noted that the member 4 in lying well below the top level of the framing is outside the path of travel of the tops edge. Due to the fact that the top 6 can be turned completely over, see dotted lines a in Figure 2, it may be thoroughly washed on its under surface as required and without the necessity of the attendant getting beneath the table. In this connection it is observed that one of the flat faces of each of the

top angle members

1, 3 lies inwardly or toward the inner space enclosed by the table members and therefore can 'be readily cleaned and consequently cannot retain deleterious matter. Clearly, the fact that the top can be reversed in position so as to be properly cleaned where it is practically impossible to renovate the under side of a fixed top is of prime importance coupled with the fact that the balance of the table, particularly since made of metal, can be cleaned of all bacteria forming matter.

.While we have shown a preferred form of our improved table we may make changes therein without departing from the spirit of the inven- ,tion and the claims thereto.

' What we claim is: v

. 1. A table including a framing, a top pivotally mounted at two opposite edges on said framing and arranged to swing to various positions within the latter, said framing including a permanently fixed supporting portion as a part thereof lying in the path of travel of one of the other edges of said top for receiving and supporting that edge upon it, and said framingv having an open side opposite said portion, and a swingable supporting portion pivoted on the framing at opposite sides of said open side to receive the remaining edge of the top and arranged to swing from beneath said remaining edge for the release thereof.

2. A table including a framing, a top pivotally mounted on the framing at two opposite edges, said framing having a supporting member for receiving upon it the full length of one of the other edges of said top, and a member carried by the framing adapted to receive upon it the'full length of the remaining edge of the top, said member being pivotally mounted on the framing .and being adapted to swing from beneath the top, thus providing a free space to permit said I top to freely swing to various positions.

3. A table including a framing, a top pivotally supported between two of its opposite edges thereon, said framing including a member to receive upon it one of the other edges of the top, and being open opposite said member to permit the remaining edge of said top to swing therethrough, a movable member pivotally supported on the framing including a rod having a length'substantially equal to the length of the top at the said open side of the framing, said member adapted to be moved into and out of the path of movement of the edge that it supports.

4. The invention according to claim 3 including means to secure the pivotally supported member in the top supporting position.

5. A tableincluding a framing, a top-pivotally supported between two of its opposite edges thereon, said framing including a member to receive upon it one of the other edges of the op, ber to permit the remaining edge of the top to swing'therethrough, and a member including a pair of arms each pivoted to the framing portions that support the pivoted edges of the top, and including a rod extending substantially the full length of the top between its said pivoted edges, said rod adapted to be stationed beneath the edge ofthe top that swings through the open side of the framing to support they same, said rod having an arm at substantially the middle of its length adapted to rest upon a'support in the top supporting position of said rod.

6. A table including a framing, a top pivotally supported at two of its opposite edgeson opposite portions thereof, said framing having a supporting member at one of its other sides to receive upon it one of the other edges of the top, the framing having an open side opposite the remaining free edge of said top through which the framing being open opposite said memsaid edge is free to swing to various positions, 311

extending between said arms adapted to swing beneath and to support upon it the said free edge of the top, and a latch for engaging and securing one'of the arms in the top supporting position.

7. The invention according to claim 6 wherein a supproting arm extends from the rod and abuts upon a part of the framing when the rod is in the top-supporting position. 1

8. A table including spaced end portions, a top pivotally supported at two of its edges thereon adapted to be reversed in position, an arm extending from said top near each of said edges substantially perpendicular to theplane of said top, and each pivoted near its base to one of said end portions, an arm extending from the top between the positions of the first named arms and on the same side from which the latter project, a rod extending through all of the arms, an arm extending from the rod between the positions of the said first named arms, and a truss rod extending across the last named arm and fixed at its ends with respect to the first named rod near the extremities thereof.
