R. L. LISLE SIGN MOUNTING Oct. 14, 1952 Filed Dec. 16, 1950 Rage-R Z. l/SLE IN V EN TOR.

ATTORNEY Patented Oct. 14, 1952 UNITED STATES PATENT OFFICE Robert L. Lisle, Dallas, Tex. Application December 16, 1950, SerialNo. 201,153

This invention relates to supporting devices for signs and the like and it has particular reference to a friction mounting adapted to support warning signs on vehicles.

The principal object of the invention is to pro- 3 Claims. (Cl. 40---125) vide a simple mounting adapted to be attached, 1

for example, to the bumper of an automobile or to the catwalk of a railroad car, to receive and frictionally hold the supporting legs or prongs of a frame on which is removably disposed a sign specifying the explosive or inflammable nature of the materials hauled by the vehicle on which the sign is mounted.

Another object of the invention is to provide afriction'mounting for signs and other devices, consisting of a housing having therein a spring biased and beveled disc or washer against which the prongs of the sign frame are urged when passed through apertures extending diametrically through the walls of the housing thus to compress the spring which, in turn, urges the washer frictionally against the prongs of the sign frame to preclude too ready withdrawal of the prongs from the housing.

With the foregoing objects in view, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawings wherein:

Figure 1 is a front elevational view of a sign frame and mounting constructed according to the present invention.

Figure 2 is a sectional View on a slightly larger scale taken on line 2-2 of Figure 3, and

Figure 3 is a view in transverse section taken on line 3-3 of Figure 2.

Continuing with a more detailed description of the drawing, reference numeral ID denotes generally a frame which may be of any desired shape but in its present form, the frame is composed of a length of wire ill, intercrossed and welded at l2, beyond which the ends of the wire are turned into parallelism to define prongs l3, the ends M of which are pointed. A sign N3 of expendable material is applied to the frame I l in any desired manner and, in keeping with the beveled housing of the invention, the sign bears indicia adapted to identify the nature of the merchandise transported by the vehicle on which the sign is mounted. Trucks and railroad tank cars in which is shipped Naphtha or other inflammable or explosive commodities are required by law to carry warning signs. The present invention provides an inexpensive and simple medium for supporting such signs.

The mounting for the sign consists of a hous ing generally indicated by reference numeral l6, as shown, this housing consists of two telescopically related, cup shaped sections 11 and 18, the section [8 being the inner of the two sections and is held in fixed relation to the outer section as by sweating 'or spot welding at 19. The inner section 58 is shorter than its companion section ll, thus to provide an annular space adapted to be occupied by a washer 2 0. The washer or pressure plate 20 has an annular bevel 2i on its outer face and bearing against the inner face of the washer is the outer end of a coil spring 22, the opposite end of the spring resting against the bottom of the inner housing section Id. The described arrangement is such that spring 22, normally under compression, exerts a force tending to move the washer 20 outwardly toward the outer end of housing 46.

The outer housing section I! is drilled to provide, on each side of a square central opening 23, axially aligned passages M which are adapted to receive the prongs 13 of the sign frame H. The pointed ends M of the prongs first enter the top openings 24 and are brought into engagement with the bevel 2i of the washer 28 and, through a. wedging action, depress the washer rearwardly against the resistance of the coil spring 22. The

prongs continue downwardly through the lower openings or passageways 24 and out of the housing, in the manner shown. Thus, the prongs l3 are frictionally held in the described relationship with the housing, by pressure imposed by the washer or pressure plate 20 through the action of spring 22. The prongs are thereby held against too ready release from the housing 18.

The cross-member 25 is welded to the prongs 13 which serve as a medium by which the prongs may be thrust into their respective openings 24 in the housing It and to enable the prongs to be more easily withdrawn when it becomes necessary to detach the sign frame from its mounting for the replacement or changing of the sign l5.

The opening 23 in the center of the outer housing section I! is preferably square to receive a correspondingly shaped shoulder 26 formed under the head 21 of a mounting bolt 28, thus to prevent rotation of the bolt 28 with respect to the housing IS. The bolt 28 extends through an opening 29 in the washer 20, thence through the spring 22 and to an opening 30 in the center of the inner housing section l8. The inner end of the bolt 28 is threaded and adapted to be passed through an opening in the supporting member 3|, which may be the bumper of a truck or a portion of the catwalk on a railroad car. A look washer 32 and a nut 35 are mounted on the threaded end of the bolt 28 to hold the same and the housing IS in fixed relationship to the supporting member 3 I.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be Within the spirit and intent of the invention.

What is claimed is:

1. A sign frame mounting comprising a housing having aligned openings in its front and rear, a beveled member movably disposed in the front portion of said housing, compression means nor' mally urging said beveled member toward the front portion of said housing, said housin having adjacent its front portion and on each side of the first mentioned openings, diametrically opposed passageways, a sign frame having parallel prongs adapted to be received in said passageways to displace said beveled member against the resistance of said compression means and means extending through said aligned openings of said housing for holding the latter on a supporting member.

2. In a sig frame and mounting, parallel prongs formed on said frame, a housing in two relatively fixed cup-shaped sections, one Within the other and defining an annular space internally of the other of said sections at the inner end of the companion section, said sections hav ing aligned axial openings, said outer section having a transverse opening on each side of its axial opening to receive said prongs, a beveled member within said annular space, a coil spring within said companion section for holding said beveled member normally in frictional engagement with said prongs and means extending through the aligned axial openings of said housing sections for securing said mounting to a supporting member.

3. In a sign frame and mounting, a housing, parallel prongs formed on said sign frame and extending through transversely aligned passageways in the walls of said housing, a. pressure plate removably disposed in said housing provided with a beveled face confronting the transverse passageways in said housing and against which the ends of said prongs engage to effect displacement of said pressure plate by said prongs in their course through said transverse passageways, spring means in said housing normally urging said pressure plate into frictional engagement with said prongs to hold the latter against longitudinal displacement in said housing, a crossmember affixed to said prongs for manipulating the same into and out of said housing, and means extending axially through said housing for holding the same on a supporting member.
