I Application sit November 22.1898. 'sean No. ssmsafeamane andexact description, reference being had to '4 the accompanying drawingain which- 'Figure 1 is a plan view' of a plate-conveying table constructed Vin accordance with my invention. Figs. i.` and 3 are .vertical longitudinal and cross sections, respectively, of the saine; and Fig. 4 is an enlarged sectional view showin g in detail the valve .which is illustrated in Figs. Zand 3. Y l j In 'the variousy forms of my invention I einploy vas-a means for-oating or iioating and conveying metal plates or strips jets of air, which are directed against the underside thereof and'maintan or tend to maint in the saine in suspension solhat they may be moved f reely in their supportingsurface, or by ar'- ranging' the air-jets at an inclination the articles may not only besupported, but may be given a forward impulse in the desired direction,',tl1c `jets being controlled by valves arranged to be opened bythe article on the coni 1 My apparatus maybe used for metal plates,
resents a box, which constitutes the body of the conveying-table and has an air-inlet 5, through which compressed air may be supplied ,to its interior. Itsysurface is alsoprovided with perforations 6, from which the compressed aircntcring through the opening 5 will owin. jets. If now a metal sheet be placedon the box 4, the air escaping through the jetopening 6 andrplayiug on the under surface thereof will tend to raise the asaine from the surface of the box, enabling the sheet to be pulled over the surface with .'v'ery' little eiort,
'j ust as metal sheets are pulled or pushed. over the caster-tables common in plate-mills.` Any number of these boxes or tablesj: may be .placed together, so as to constitute a conveying-table of the desired size. f
To A'prevent useless was-te of air from those oftheyjebopenings 6 which are not covered.
by the plate, I use the valve arrangement illustrated in Figs. 2, 3, and 4. For this purpose I prefer to make the perforations on the inner side of thetop plate of the box 4 flaring, so as to 'afford seats for ballvalves '7, which are backed by suitable springs 8 and project somewhat above tlietop surface of the box, as
shown in Figs. 2 and et, Normally these halls close theopenings 6 and prevent the escape of air; but when the plate is laid upon the top of the box its weight will press Adown' the balls, thus unseating them and permitting the air to escape through the openings and to act asabove described. The perforations may l y be inclined instead of at right angles to the surface of the table and provided with snit- `able valves, the jets-v in such case movingor aiding in moving the article over the table. 'Illu-:apparatus can thus be used as an eclent substitute for conveying-tables provided with feed-rolls. i I y An important feature of my invention is that the air, in addition to supporting the strip or in the following claims the skilled mechanic may make many changes in the form and arrangement of the parts without departure from my invention, sincev What I claim is K 1. .A conveying apparatus or table having upwardlyfdirect'ed jets, means for delivering. fluid therethronglrto impinge upon articlesl placed thereon, and valves closing said jets and adapted to be opened by the article placed' upon the conveyer,substantially as described. 2. Conveying apparatus compr'singatable having `jet-openings, and valves closing the saine and protruding beyond the surface of theI table, said Valves beingadapted to be engaged by a superimposed article and to be opened thereby, substantially'as described. In testimony whereof I have hereunto set my hand.` Y THEO'. J. YOLLKOMMER. Witnesses:
