" Application filed May 6, 1915. Serial No. 26,262.

To all whom it may concern:

Be it known that I, JOHN M. ROHLFING, a'citizen of the United States, residing at the city of St. Louis, State of 'Missouri, have invented a certain new and useful Improvement in Nailing-Strip Mounts for Freight-Cars, of which the following is a full, clear, and exact description, such as will enable others skilled inthe art to which it appertains to make and use the same, refe'rence being had to the accompanying drawings, forming part of this specification, in which v Figure 1 is a cross sectional view through a freight car showing the arrangement of my improved nailing strip mounts; Fig.2 is an enlarged sectional view through one of the mounts; Fig. 3 is an elevational view of one of the mounts.

This invention relates to'a new anduseful improvement in nailing strip mounts for freight cars and consists of a simple, easily applied device, a plurality of which mounts are preferably countersunk in the side wall of the car whereby. nailing strips 'of wood may be detachably secured in position either vertically, horizontally, or at an angle -as the requirements of the particular lading being transported demand.

Heretofore, and indeed so-called automobile box carhas. been, and is usually constructed with its side walls arranged inside the posts and'diagonals constituting the side framing of the car. This is known as a sheathingless car on account of the absence of the outside sheathing. It is obvious that the lining or wall arranged inside the posts and diagonals provides a smooth uninterrupted surface which is very desirable in loading and unloading certain classes of freight, suchas automobiles, etc.

It is very desirable, if not necessary, in packing freight, such as automobiles, in a car of the character described, especially where the machine is assembled and runs, on its own wheels, to prevent all movement of the lading incident to shocks and jars to which the car is subjected. To accomplish this, it has been the practice in some cases to nail cleats against the side walls at proper points so as to provide a nailing base to which the ends of cross timbers are attached, said cross timbers being so disposed as to prevent longitudinal shifting of the load. These cleats may also be used for at present, the

the attachment of cross timberslon which a supplemental flooring is secured whereby a greater quantity of freight may be packed:

in the car with little or no danger ofthe different pieces or assembled partscontacting with each other possibly to the mutual injury of their paint, or finish. These cleats, cross timbers, and supplementahfiooring boards are provided by the shipper, and when the car reaches its destination, are generally removed by: the consignee with the result that in many 'cases the side walls of the car are puncturedby the nails used for securing the cleats in position. These nail holes thus left in the side wall provide ways for the ingress of water into the car to the detriment of subsequent shipments,

and for such injuries occurring in transit,

the railroad is, of, course, responsible. Further, the repeatedinsertion and removal of nails splinters the side walls and rail, and dust accumulating in the nail holes causes the side wall to rapidly deteriorate.

My present invention contemplates the use of small metal sockets, preferably countersunk, in the sidewall so as to preserve the smooth inner surface thereof, said sockets being arranged at such locations as experience dictates, They may be in two horizontal rows and extend throughout the entire length of the car, as shownin Fig. 1-, or they may start at a given point from each end of the car.

In the drawings, 1 indicates the side wall of the car'which at desired points is recessed, preferably by an augur, to receive a metal socket 2 preferably made circular inform to fit into the circular recess in the side wall and be flush with the inner face thereof. A. bolt 3 is shown for securing the socket in position, said bolt passing through an op'eningin the back wall of the socket and side wall of the car, but it is obvious that many other formseof fasteningdevices'may be used, if desired, to secure the socket in place.

' 2 indicates wings extending inwardly toward each other and constituting front 7 H y rangement for receiving the head of a bolt 4 passing through a wooden cleat 5.

The head of bolt 4 is prevented from turning by engaging the lower wall of the socket, and hence the nut on the inner end of this bolt may be turned up so as to secure the cleat firmly in place. In introducing the head of bolt into position, the same is turned so that its faces lie at angles of and when in the key hole the bolt is turned so that its faces are vertically and horizontally disposed, thereby enabling it to fit squarely against the bottom Wall. When in this position, if a cleat should accidentally be raised so as to locate the head of the bolt opposite the enlarged portion of the key hole opening, the head of the bolt cannot pass througlnas it is necessary to turn the bolt head to its introducing position before it can be removed.

From the above, it will be seen that removable cleats are provided which can be placed in any desired position, vertically, horizontally, or at an angle, said cleats forming nailing strips for cross timbers, floor supports, etc., and when the cleats are removed, the side walls of the car are not injured in any way, and the smooth, unbroken surface of the wall is preserved.

What I claim is:

1. The combination with a car wall of a socket mount whose front wall is provided with an opening, the upper portion. of which is enlarged so as to receive the head of a bolt, and a bolt whlch, when its head is introduced into said opening, is turned 7 1 1esses,'this 19th day of April, 1915.

to secure proper cooperation with said socket mount.

2. The combination with a car Wall of a socket mount which is circular in shape and whose front wall is provided With a key hole opening designed to cooperate with a bolt head, the upper enlarged portion of said opening preventing the removal of the bolt head when said bolt head occupies its" engaging position relative to said socket mount.

3. The combination with a car Wall of a socket mount which is circular in shape and provided with a key hole opening in its front wall, means for securing said socket mount to said car Wall, a bolt, the

head of which is adapted to pass through the key hole opening in the Wall of the socket mount, and a nailing strip supported by said bolt.

4. The combination with a car wall of a nailing strip mount comprising a substantially hollow member seated in said Wall, means for securing said member to said Wall and a nailing strip engaging bolt having its head removably seated in said hollow member. 1

5. The combination with a car wall, of a cup-shaped socket counter-sunk in said wall, means for rigidly fixing said socket to said wall, lugs integral with the front of said socket, which lugs are spaced apart and arranged to form an irregular opening, and a nailing strip supporting bolt, the head of. which is adapted to pass through said irregular opening and engage behind the lugs on the socket.

In testimony whereof I hereunto afiix my signature in the presence of tWo wit- JOHN M. ROHLFING.
