To all /w/iom t may concern lle it known that l, Exim. l. @einen a citizen of the TUnited States? residing :it Hartford, Connecticut, have invented n cer` tfiin new and useful improvement in Wall- Grises, oi? which the following: is it -tull7 clear7 and exact description.

My invention relates to-1in1provements in sectional wall cases, sind has for its object to produce :i will cose which cnn he easily huilt up from n few number of parte and added to indelinitel;T so that it may he enlarged :is desired.

lt further has for its ohject to produce Wall cose, the ports of which when disassembled take up but little room. :ind ure easily nninufoctured.

lt further hns for its object to reduce the numher 01": fzirts necessary @ind reduce the number of slfinping and bending operations.

lt urthei' has tor its otject to reduce or eliminate the necessity of rivotii'ig.

The 'following is :i description of an embodiment ol my invention, reference being had to the accompanying drawings, in Which- Figui'e l is e perspective view of n. Well cese embodying' my invention. Fig. t2 ii `longitudiinil section of the sinne on n vertical plone 'passing' through the center thereof. Fig. 3 is o perspective view olI an intermediate member. -i is a. perspective view of one of the transverse plate n'iemhers. Fig. 5 is :i side elevation partly in section of o. tubular spacer. Fig. 6 is n. Side elevation of a connector. Fig. 'i' is n side elevation of et nut l'or connecter.

Referring more particularly to the dreivings,1-l-- nre transverse nienihiiers consisting of lint plates haii/'ing punched therein the holes 2N2, "VMEZ, 3- notch 4C ino round h 6 isV an srshaped interi. having the usuel conductor open. :is punched 'therein end side projections t---S and SHQ, the prcjiections 8m@ being locuted at heights corresponding 'to' the holes and 3-3 and the projections SWS) heilig located :it heights coi-respending` to the openings 2--2 and 25%? in plates l.

In a Wall case, the combination of two `end plates provided with openings adjacent to each of their ends, intermediate separatlng means having vertical and horizontal portions provided on both sides with projections which enter said openings in the plate members, and clamping means passing through said two plate members and be- 4 plate members, a

tween the upright portions of said separating means.

2. In a wall case, the combination of two end plates provided with openings adjacent to each of their ends, intermediate separating means having vertical and horizontal portions provided on both sides with projections Which enter said openings inv the plate members, clamping means passing through said two plate members and between the upright portions of said spacing means, and a spacer surrounding said clamping means.

3. In a Wall case, thecombination of two end plates provided with openings adjacent to each of their ends, intermediate separating means havin vertical and horizontal portions providedg on both sides with projections which enter said openings in the headed externally threaded clamping screw passing through said two plate members and between theaipright portions 'of said spacing means, said clamping screw having also a screw threaded recess in its head adapted to receive the externally screw threaded portion of a similar clamping screw.

4. In a Wall case, the combination of two 'portions provided on both ratingmeans entering offset openings inA said plate members.

5. In a wall case, the combination of two' end plates provided with openings adjacent to each of their ends, intermediate separating means having vertical and horizontal sides with projections which enter openings in the plate members, clamping means passing through said ltwo plate 'members and between the upright portions of said separating means, said separating means being Idivided so as to form two L-shaped membersi (l. In a wall case, the ccnibipation of two .end plate members providedjwith openings adjacent to each of their ends', intermediate L-shaped separating means having vertical and horizontal portions provided on both sides with projections which enter said openings in the plate members, clamping means passing through said two plate members and betweenthe upright portions of said separating 1neans,'said end plate members beingT each provided with an opening near its bottom and the lower ends of said L-shaped separating means being provided on cach side with lateral projections adapted to simultaneously enter said last mentioned openings.

7.
