NAILING BLOCK F iled Oct. e, 1927 min Patented Sept. 3, 1929.

UNITED STATES ISAAC A. BA'UM, OF CHICAGO, ILLINOIS.

NAILING BLOCK.

Application filed October 6, 1927. Serial No. 224,369.

My device relates to framing for wall openings, and particularly to means for attaching wood trim to such metal framing.

In my copending application, Serial No. 224,366, filed of even date herewith, I have disclosed a metal frame construction for wall openings and have provided for the mounting of wood blocks at intervals therein, these blocks being adapted to receive nails for holding wood trim.

In order to avoid the use of any wood for I plete device, and

Fig. 4 is a detail showing the form of connection between adjacent plates.

In the drawings, I have shown a channel shape frame member such as contemplated by me and although a frame element of this cross section is satisfactory, I am aware that other sections may be employed to advantage. The channel comprises a web 10, flanges, 11 and a plaster terminal margin 12. To the web of the channel is secured at intervals a U-shaped support having a face 13, sides 14; and attaching'flanges 15. The flanges 15 are riveted or welded to the web 10 of the channel.

While I have shown but one of these devices, it will be understood that they will be located at intervals in the length of the frame elements.

The nail securing device includes

plates

16, 17 each being corrugated and arranged in parallel, adjacent relation. Preferably the plates are formed by doubling a section of metal on itself, one of the terminal flanges 18 being riveted or otherwise secured to the under side of the face 13 of the U- shaped support, while the other flange 19 overlies but is not connected to the flange of the channel. The flanges are so bent as to provide a V-shaped entrance opening to the space between the two plates in order space.

As a means for preventing separation of the plates when a nail is driven therebetween, a number of different devices may be employed. Preferably I utilize tongues 20 extending from the edge of one of the plates, the tongues being bent over, as best shown 1n Fig. 4. The metal composing the plates and the securing tongues will be comparatively stiff and rigid and so designed as to prevent distortion by the nails driven between the plates. In joining the plates by means of the tongues or otherwise, pro- VlSlOIl will be made for separation to the extent of the lateral thickness of the largest nail that will be employed. A nail may readily enter the space between the plates, but as it is driven inwardly, it Will be distorted or bent to conform to the contour of the corrugations in the plates. Therefore the force necessary to withdraw a nail will be substantially the same as that to seat it.

The illustration of Fig. 3, shows the position of the parts with a door j amb applied in place. The jamb is indicated at 21, wedges at 22 and nails at 23.

The provision of the support with the broad face 13, enables the seating of the wedges 22 which are held in place by the nails in the usual manner. The nail receiving device being independent of the channel, there is no tendency to distort or spread the channel by the action of the driving of the nails. 7

Obviously the construction illustrated is capable of considerable modification, and I do not wish to be limited except as indicated in the appended claims.

I'claim:

1. The combination with a channel shaped metal frame of a U-shaped support mounted within the channel, a pair of adjacent parallel corrugated plates secured to the support, and means joining the two plates to permit a nail to be driven therebetween.

2. In framing construction the combination of a channel shaped frame member, an angular trim support secured to said frame, and'a pair of metal nail receiving devices said nail receiving devices comprising a corrugated sheet of metal bent back on itself to provide a nail receiving slot, one edge of said nail receiving devices being secured to said angular support and the other edge to accurately guide a nail into the proper being adapted to contact the flange of said channel frame member.

3. In framing construction the combination of a channel shaped frame member, a

5 U shaped trim support secured to said frame, and a pair of metal nail receiving devices, said nail receiving devices comprising a laterally corrugated sheet of metal bent back on itself to provide a nail receiv- 1 ing slot, one edgeof said nailreceiving devices being secured to said U shaped sup port, and the other edge being adapted to contact the flange of said channel frame member, said nail receiving device having means thereon permitting limited lateral opening.

In testimony whereof I have afiiXed my signature.
