tion to provide a device of this character by the use of which the connecting blocks may be fastened securely to a'wall without the necessity of using screws and by the mere punching of a hole in the wall of the proper size to receive the connectlng block.

It is also a purpose of this invention to provide a device of this character in which, Whenever it is necessary to do so, the connecting block may be detached from the casmg upon which it is secured, for purposes of p I bers 15 and 16, which aresubstantially the repair.

Other objects and advantages of the in vention will appear as the description pro-" coeds, in connection with the accompanying drawings, wherein the preferred form of the invention 1s shown. It is obvlous, however, that various modifications may be made" from the exact details shown and described, and it is to be understood that I intend to avail myself of all such modifications as will Fig. 2 is a section on the line 2-2 of Fig. 1; and

Fig. 3 is a section taken through the casing, showing the connecting block partially inserted in the holding means.

Referring now in detail to the drawings, there is shown at 5 a portion of a wall, which may be the wall of a radio cabinet or power unit case, and which wall, as is common in present practice, is constructed of a relatively thin metal construction. 1 The material of the wall, however, is not important to the present invention, as our improved securing.

means is applicableequally well to various types of casings. The wall, as shown, is cut outto provlde a rectangular aperture 6 conforming in such as indicated at 13 and 14 therein.

shape to'the top 70f the socket portion of the connecting block. This connecting block, as shown, has longitudinal ridges 8iand 9 extending lengthwise thereof at a 'short'distance' below the top 7 This connecting block, of course, has terminals, as indicated at 10 and 11, for connection to'the electrical apparatus within thecasing, and co-opera-tes withthe plugportion 12, having terminals The details of this connecting plug form aseparate application filed March 11, 1929, by Howard'B. Jones, and bearing Serial No.

Now the means for securing the socket portion of the connecting block to the wall 5 consists of a pair of elongated spring memlength of the aperture provided at-6 in the wall 5. Thesespring 'members 15 and 16 .are bent, as shown at 17 and 18,--to--form grooves fitting over opposite edges of the aperture 6. The spring members are'then curved downwardly and inwardly, as shown clearly at 19 and 20, and are provided with the upturned edges 21 and 22 which press against the lower edges of the ridges 8 and 9, as shown more clearly in Fig. 3. At the opposite ends of the members 15 and 16,

these edges'2 1and 22 may be cut away slightly so as to'facilitate the insertion of the block there'between, but this, of course, is not necessary in all cases.

Now, in mounting the block in position,

the members 15'and 16 are first fitted in position, as shown in Fig. 3, and then the block is inserted between them at one end block is then pressed along beneath the wall so that the edges 21 and 22 engage the under sides of the ridgesS and 9 and tend to press the block upwardly against the wall 5. The

by sliding it relative to the members 15 and V .16 until it aligns with the opening 6, and, when the block is in suitable alignment with the opening 6, the resiliency of the members 15 and 16.willv force the block upwardlyinto the position shownin Fig. 2, so thatthe portion 7 thereof is substantially flush with the tops of thebent portions 17 and, 18 onthe members '15 and 16. p x

' The block is now mounted in position for permanent use,"si'nce it cannot'slide endwise due to the projection ofthe portion 7 up- "the portion? below the level of thewall and then sliding the block endWise-out of engageinentwith the spring members and16. c From the abovedescription, itis thought that theconstruction and advantages of this l Letters Patent 1s device will be clear tothose skilled in this i ;art,,andihaving thus described our invention,
