If desired, modifications: the structure illustrated in Fig. 3. openings 25 may be P d d in t e m m er ll Referring to the drawing, and particularly to to permit it to be compressed more easily into Fig. 3, the resilient mounting unit shown therein the space in the channel l2. comprises a solid support member or block ill It will be seen that the present resilient unit may be completely assembled inthe switchboard structure prior to the installation or the switchboard on the deck ll. installed, a bolt 26 may be inserted into the block Ill from underneath the deck ll, thereby securing the switchboard structure to the deck. If desired, the bolt 22 may be made of suificient length to extend through the deck I l and secured thereto by a nut 21 in the manner shown in Fig. 5.

It is evident that motion of the switchboard structure is restrained in all directions. Thus, motion in a horizontal direction acrossthe channel I2 is restrained by compression of the resilient member 18 between the block i and the flanges oi the channel. Motion in a horizontal direction along the channel is restrained by compression of the resilient member l8 between the block l0 and the gussets 24 disposed across the channel. Vertical motion of the deck ll upwardly is transmitted to the switchboard by the resilient member l8 and vertical motion down.- wardly is transmitted by the resilient member l9.

After the switchboard is support membe a load supporting channel having its web disposed above and its flanges spaced from said support member, said channel having transverse gussets therein, a cup-shaped resilient member disposed in the space between said gussets and between said channel and said support member, a second resilient member disposed on the opposite side or the web of said channel from the first resilient member, a top plate on said sec--' I member disposed in the space between'said gus- Itwill be seen that the present resilient mounting unit requires only two pieces of rubber or f.

other resilient material for each unit. The meniber l9 may be easily cut from a sheet of material,

and, as explained hereinbeiore, the member I8 is molded to fit a recess in the channel 12. Furthermore, no bonding between the resilient and the metal members is required. Thus, the present structure is relatively simple and increases the overall height of a switchboard structure by only a small amount. If desired, the plate 13 may be omitted from the structure and the upright members i5 welded directly to the top of the channel l2, thereby further decreasing the overall height of the switchboard structure.

From the foregoing description, it is apparent that we have provided a resilient mounting unit which may be utilized for resiliently supporting switchboards and similar structures which are subjected to shocks of a high intensity, such as would be caused by an explosion. The resilient mounting unit may be readily incorporated in a switchboard structure of a standard design and as many units as are required to support the weight of the structure may be provided.

We do not desire to be restricted to the particular form or arrangement of parts herein shown and described, since it is evident that they may be changed and modified without departing from th spirit and scope of our invention as defined in the appended claims.

We claim as our invention:

1. A resilient mounting unit, comprising a solidsupport member, a load supporting channel having its web disposed above and its flanges spaced from said support member, said channel having transverse gussets therein, a cup-shaped resilient member disposed in the space between said gussets and between said channel and said support member, a second resilient member disposed on the opposite side of the web of said channel from the first resilient member, and a bolt extending through said resilient members and threaded into said support member to compress said resilient members, the web of said channel having an opening therein materially larger than th diameter of the bolt.

2. A resilient mounting unit, comprising a solid sets and between said channel and said support member, a second resilient member disposed on the opposite side of the web oi. said channel from the first resilient member, a top plate on said second resilient member, a bolt extending through said top plate and said resilient members and threaded into said support member to compress said resilient members, and a spacing sleeve dis-' posed on said bolt between the top plate and said support member to limit the compression of said resilient-members, the web of said channel having an opening therein materially larger than the diameter of said sleeve.

4. A resilient mounting for supporting a switchboard structure on a deck or similar surface, com-- prising a solid support member disposed on the deck, a channel having its web disposed above and its flanges spaced from and overlapping said support member, said switchboard structure being securedlto said channel, a cup-shaped resilient member disposed between said channel and the support member, a second resilient member disposed above' the web of the channel, a top plate on said second resilient member, and a bolt extending through said top plate and said resilient members and threaded into said support member to compress said resilient members.

5. A resilient mounting for supporting a switchboard structure on'a deck or similar surface, comprising a solid support member disposed on the deck, a channel having its web disposed above and its flanges spaced from and overlapping said support member, said channel having transverse gussets therein, said switchboard structure being secured to saidchannel, a cup-shaped resilient member disposed in the space between said gussets and between said channel and the support member, a second resilient member disposed above the web of the channel, a top plate on said second resilient member, and a bolt extendin ROBERT L.
