TABLE GQNSTBUCTIUN.

Application filed March 19, 1821. Serial No. 453,554.

To all 207mm it may concern Be it known that 1', Homer Joan-ire, a izen of the United States, residing at ohicag'o in the county of Cook and State oi? 5 Illinois. have invented a certain new and useful Improvement in Table Constructions,

of which the following is a full clear, concise, and exact description reference being id to the accompanying drawings forming art or this specification. This invention relates to tables and more particularly to a sanitary table construction vrhe in the framework of the table is made en irely of members having curved outer surfaces to avoid all ledges and angular embers in the construction and thus pre vent the accumulation of dirt and other undesirable matter.

The general principle of the invention can be apgiilied to ordinary tables with fixed tops of any sort and to tables provided with movable tops or conveyors as well, both forms being shown in the accompanying drawings.

lit is a purpose of the present invention to provide a table of the above mentioned character the framework of which is made up entirely of members that substantially circular in cross section to thus avoid ll ledges upon which dirt or other may lodge.

it is further purpose of theinvention to provide table comprising members er:- tending vertically itrom top to bottom cl said framework upon which bracket mom-- bers are mounted for securing transverse and longitudinal members thereto, said 1118'5l3- her being continuous and extending through said bracket members. so it is another purpose of the invention to provide a tabletl ramework comprising ver tical members continuous from top to bottom thereof, connect-ed tog-reazher by means of continuous transverse members both said transverse and said vertical members having members mounted thereon having sleeve like portions extending; around said vertical and transverse members for connecting said vertical and transverse members together and for securing longitudinally extending members thereto for completing said framework. The connected transverse and vertical members form a frame or section constituting structural units any member of which may be connected together by means of longitudinally extending members to form a table of any desired l ngth. The longitudinah transverse and vertical members are p-ei erably formed of tubular members circ lar in cross section and the connecting members are preferably made. in the form of castings of any desired configuration and provided with circular bores therein to receive one or more of the tubular members as desired. The tubular members preferably extend through said castings or fittings and the castings or fittings are preferably held in place by means of set screws in the position that it is desired to place them to construct a table for a desired purpose.

It is a still further purpose of the invention to provide a table carrying a conveyor or other mechanism of a similar character with a framework of the above mentioned character provided with suitable fittings mounted on any of said ransverse or ver tical members in any desired position thereon to properly support the mechanism mounted on said table, said fittings-being passed over said tubular members so as to embrace the same and being secured thereto by means oi set screws or similar fastening means as described above.

It is another object of the invention to provide a conveyor on a table of the general character described above that is readily cleanable so constructed that the same can be thoroughlysterilized, said conveyor comprising pairs of side chains having ind vidual pans arranged therebetween in 'a'htly spaced relation.

vention will appear the description of the accompanyingdrawings showing certain forms that my invention may take proceeds. However, desire to have it distinctly understood that I do not intend to limit myself to the exact details shown or described but that I intend to include as part of my invention all such obvious changes and modifications of parts as would occur to a person skilled in this art and as would fall within the scope of the claims.

in the drawings:

Fig. 1 is a side elevationof my improved table structure provided with a fixed top;

Fig. 2 is. an end view thereof, the top being shown in dotted lines therein;

Fig. 3 is a section taken on the line 3-4-3 of Fig. 2;

@ther objects and advantages of the intically extending i'i'ieinbers 7 Fig. 4i. is a side elevation O'i a table constructed in accordance with my lnvention, said table being provided with a conveyor mechanism.

Fig. 5 is section taken on line 5-5 of Fig. 4; and

Fig. 6 is a fragmentary plan view oi the table shown'in Fig. l.

Referring to Figs-1 to 3 inclusive of the drawings a table is shown comprising a framework having vertically extending posts 7 which are continuous from top to bottom of the vi ramework. The lower ends of the posts 7 have mounted thereon the flanged sleeves or collars 8 forming feet for said posts or legs 7. Suitable transversely extending members 9 are provided which are continuous from one of said vertically extending posts or legs 7 to the other there of and are secured thereto'by means of coupling members 10 and 11. T he members 10 and 11 are provided with bores or openings extending ther'ethroughfrom end to end thereof and are adapted to receive the vertherethrough. The members 10 are provided with laterally extending bracket or ear portions 12 having a bore 13 extending therettfiough, said here being adapted to receive the lower transversely extending member 9. The members 11 are provided with bores similar to the members 10 for receiving the vertically extending members 7 a d with socket portions 14 for receiving the members 9, and with laterally projecting brackets or cars 15 each having a bore 16 extending therethrough for receiving the longitudinally extending members 17. Each of the members 8, 10' and 11 is secured to the members cooperating therewith byme'ans of set screws 18, said screws being omitted in Figs. 1 to 3 in the drawings, except at the" members 1.0 in 2 and the member 10 at the right of Fig. l. The upper trans erse member 9 and the upper coupling members ll are adapted to, support a stationary table top 19, the table top 19 being secured to the mentibers 9 by means of the -shaped strap mcmbers 50 secured to the table top l9 in any desired manner. The members '7 9 and 17 are preferably circular in crosssection as will be clear it om the drawings, and the coupling members 10 and 1]. and the flanged members 8 are preferably provided with curved outer surfaces so as to avoid any lodging places for dirt or other foreign mat ter wherever possible.

It will be noted that the members 7 and 9 and the coupling members connecting the same form a table framework section and that any one of these sections may be joined together by means of the longitudinally extending tubular members 17 form table otanydesiredlength.

It will also be seen that in constructing v portions thereof that would not be of standardized size would be the members 7, 9 and 11, these members varying'in accordance with the size of the table by varying only in one dimension, that is, the length. The same size tubing is used for all purposes so asto be adapted to be passed through the castings 8, 10 and 11 so that a single size of casting for each purpose can be used for all tables.

it will also be noted that the position 01": the members 10 and 11 can be varied along the vertically extending members 7 it desired, the same being preferably assembled with the vertical members in the following manner: The castings 8, l0 and 11 are passed over the members 7 and are bunched at the lower end thereof, the members 8 being se HiGjTllJQlS 11 are moved into their Position adjacent the upper ends or the members 7 and secured in place by means of the set screws.

transverse and longitudinal braces desired. It (lQSlTQCl the general prlnclple of the table construction outlined above can be applied to a table provided witha moving top or conveyor, such as is shown in Figs. 4 to 6 inclusive. In the form shown in Figs. 4 to 6 the vertically extending members 7 having the "flanged feet members 8 are used as previously described in connection with Figs. inclusive, and these are providedwith the members 10 carrying the transverse bracing members 9 as described in connection with Fin s. 1 to 3. The members 7 are also provided at their upper ends with the coupling members 11 shown in Figs. 1 to 3 inclusive and which are adapted'to carry the longitudinally extending members 17 as described heretofore. The members 11 are used for supporting the transverse members 9 which are identical with the members 9..

but which are adapted to carry the conveyor mechanism in the manner described below. Mounted on the transverse members 9 are the castings 20 provided with transversely '22, which are provided with bores extending vertically for receiving the vertically extending members 21 "and with socket members 23 Any number of members 10 and 11 can be used, dependlng upon the number of for receiving the transversely extending tubular member 24, which member 24 serves to brace and space said members 21 properly. The members 22 are provided with bracket portions 25 which are adapted to receive the longitudinally extending tubular members 26 which serve as guideways for the rollers 27, which are secured to the underside of the conveyor pans 28 by means of the bracket members 29. The members 9 also have mounted thereon so as to hold the same the members 30 which carry guide members 31 for the side chains 82 and the conveyor pans 28 extending between and connected to opposite pairs of links 33 of said chains, as will be clear from Fig. 4. The pans 28 are slightly spaced at all times, the same being shown as being spaced when traveling in a horizontal direction, as will be seen at the upper right hand side of l lg. 4. The conveyor chains 32 pass over the sprockets 34: at one end of the table framework and over the adjustable sprockets 35 at the other end of said framework, said conveyor chains being driven in any desired manner. Sprockets 35 are adjustable by moving the block 36 lengthwise in the guideway 37 so as to properly adjust the tension of the conveyor chains. In a table of the character described above, it is desirable to have a rigid construction due to the fact that moving parts are mounted thereon, and preferably additional coupling members 38, which are provided with bores extending therethrough for receiving the members 7, are-mounted on the vertically extending members 7. The members 38 are also provided with ears or projections 39 providing sockets 40 which are adapted to receive the longitudinally extending bracing members 41, the same being held in place by means of the set screws 18 as previously described.

As will be evident from Fig. t the members 17 and 41 also serve in the type of table shown to hold certain parts of the conveyor mechanism. It is of prurticular importance to provide a conveyor that can be readily kept in sterile condition in packing houses and similar places, especially where the conveyor is used for carrying parts of the animals that have been condemned as being diseased. or which are under suspicion of being idiseased along with parts that have passed inspection.

it will be seen that ii the conveyor is not thoroughly sterilized at every revolution thereof that a conveyor section that had previously carried parts of a diseased animal might be used for carrying parts of an animal that had passed inspection and thus contaminate the material that has been passed as being in a healthy condition. The material carried in a conveyor of this character usually contains quantities of blood which is adapted to flow between ad.-

joining sections of aconveyor having flights, such as are ordinarily used when the same pass around the sprocket w eels, and these sections being held clcs h gether at their adjacent edges when passing through a sterilizing chamber, sucn as the chamber 42, these edges will not be properly sterilized and the material that remains clinging thereto is quite liable to nate the next lot that is placed on the conveyor section. However, with the pans shown all sides thereof are exposed to the action of the sterilizing medium in the sterilizing chamber 42, and this diiiiculty is overcome, thus producing a more sanitary device. The upper end portions of the vertical members 7 are preferably provided with the coupling members a3, which are adapted to carry the longitudinally extending guard members 4%, as will be clear from Figs. 4 and 5 of the drawings.

it will thus be seen that a table construction is provided that can be used both for tables with stationary tops and with tables carrying conveyors and that very simple and. sanitary structure is provided which can be adapted for tables of any size and for any purpose, and that a conveyor mechanism provided for conveyor tables that have individual pans, whereby the same can be more readily sterilized.
