Specification offlfietters Patent.

Application filed April 29, 1907. Serial No. 370,746.

To all whom it may concern;

Be it known that we, Gnonen COLLIS and OLIVER D. COLLIS,"bOth citizens of the United States, residing. at Dubu ue, in the separable letter trays that may be manufac-' county of Dubuque and Stateof owa, have invented certain new and useful Improvemerits in Sectional Stacked Letter-Trays, of which the following is a specification.

Our invention relates to letter or package trays, and the object is-to provide a-series of tured singly and nested whenvshipped and thefil built up or added to at pleasure when use It consists preferably of woven wire trays of the size-and shape desired and in means view of the different parts of t e e'gs or modified forms of our invention.

standards before they are united together. Fig. 3 and 4 show partial side elevat1ons o 1 Like characters of reference denote corresponding parts in all of the drawings.

Referring to the drawings 2 designates the 1 bottom of the tray, 4 the sides, 5 the rear end i and 6 the front end, and isiconstructed of wire woven together ,flhe end 6 is cut away for the purpose of readily remov ng the let- 'ters from the tray. At each corner the wire is formed into a ring or loop 8..

The legs or standards are formed in sections according to the number of trays with -which they are used. In Flg. 1 when there are three trays the lower tray 10 is provided with the'standards 12 having feet 14. On

the upper end of each of these standards 12 is formed a screw 11. The section 15 which sustains the next tray 17 aboveis, rovided 50 thescre-w 1.1 on the standard 12. The standwith a screw threaded opening in its lower end adapted to been aged by the up er end of-the standard 12. n the upper en of the standard 15"is formed a screw 16 the same as v ards 18 which engage and sustain the upper tray 19 are duplicates ofthe standards 15 jhaving the screw threaded openingm their nj glgwer end and a screw thread-21 on. the top of each. On the top of eachstandard 18 is a an ornamental head which tray and gives the apfpearance. The

or use with this screw havin screw holds; own the to combined tray a finished manner of setting them 11 standard is by inserting the screw of the standard 12 through the loop 8 and then screwing the said standard into the lower end of the standard 15, bringing the shoulders of the standards 12 and 15 against the top and bottom sides of the loop 8 thus holding the 100 or corner of the tray rigidly between the en s of the two standards 12 and 15, and

then'by screwing upon the top of the standard. 15 the head screw the'top tray is held down and combine the two trays rigidly together; Ifitis desired to add another tray, then the'head screw 20 is removed and another set of standards 18, are brought into engagement with the standards 15 the same as thestandards 15 were connected tothe' standards 12' and then the head screw 20 is brought into enga ementwith the to of the stan ards 18 and t e third tray is ad ed, and thus the trays may 'be added at pleasure. It will be seen that the adding" of one ormore trays will in no manner interfere with the use of any tray beneath, as the letters can be removed readily from the, end 6' of each of the traIys'.

11 Figs. 3 and 4 is shown a different mode offorming the. legs or standards, though their 0' eration is practically the same as those .s own in Figs. 1 and 2. In Fig. 3 there is attached to the railing rod or wire 25, that-surrounds the tray and in which the loops 8 are formed, a rod 28, which extends down in the inner corner of the tray at the angle of the tray and through between the meshes ofthe tray at the bottom and then twisted into a loop 30. In this Fig. 3 the ,loop is-shown, forconvenience as projecting outwardly, but referably these loops should project inwardly beneath the tray where they will be out of sight. The standards 32, whlch join these loo s with the loop 8 are eachprovided wit a 100 34 at the upper end and a loop 35 at the ower end whlch loops are arranged in parallel planes and the standards set at an angle. The trays are removably attached together by inserting a screw 38 through the loop 30 and loop 34 40 and then inserting a screw 42 through the 'loop'35 8 in the lower'tray and securing bolt 45 provided with a large head 48 is passed through between the meshes of the tray at the bottom corners and engages the loop 34 and removably secures the standards 32 by a screw 50, or the loop may be screw threaded and the bolt engage the loop and be screwed therein. By this mode all that is necessary to add a tray is to insert the bolts through the loops 8 of the lower tray and the loop 35 of the standard 32 and tighten the screw on the end of the bolt.

The manner of shipping the trays is by removing the standards and then packing or nesting the trays.

Having now described my invention what I claim is:

1. In a device of the character described, a plurality of wire trays a plurality of tray standards secured to the bottom of said trays, and means carried by each tray for securing thereto said standards of the next adj acent tray.

2. In a device of the character described, a

plurality of wire trays, standards detachably eeepee secured to the bottom thereof, loops formed in said trays and means for securing said standards of each tray to the loops of the tray next adjacent.

3. In a device ofthe character described, a plurality of wire trays, rods secured thereto, standards secured to'said rods, loops formed in said trays and means for securlng the standards of each tray to the loops of the tray next adjacent.

l. In a device of thecharacter described, a plurality of trays, and means carried by the bottom of each tray for securing thereto the top of the tray next adjacent.

5. In a device of the character described, a

plurality of wire trays, .a plurality of tray standards secured to the bottom of said trays, and means carried by the top of each tray for securing thereto the standards of the next adjacent tray.

In testimony whereof we affix our signatures in presence of two witnesses.
