3 Claims.

This invention relates to moving and trucking devices and deals with a novel improvement in a dolly developed for a particular use in the motion picture industry. However, it will become apparent to those versed in the use of dollies that a device of the type to be hereinafter described will have usefulness in other fields requiring moving apparatus. 7

In the motion picture industry there arises many occasions when entire prefabricated walls must be moved from place to place on a set. These walls generally entail a heavy construction and usually must be moved with a great deal of care to avoid marring or rupturing, since they oftentimes must be moved in and out of place several times during the photographing of a scene.

The dolly embodied in this invention has been built for this specific purpose and comprises a novel feature whereby one of the side plates may be actually collapsed so that a wall may be mounted on the dolly without lifting it over the side plate and may be secured between the side plates by adjusting the plate to the wall thickness. Briefly stated, this feature consists in making one of the side plates movable on the dolly platform, whereby the plate may be adjusted to accommodate walls of difierent thicknesses and also ma be hinged over the end of the dolly platform and placed in an out-of-the-way position for loading the wall on to the dolly. Under this arrangement the wall need be lifted only a few inches to the dolly platform and the movable plate may be moved in and fixed to the wall regardless of its thickness.

Other features and advantages will become apparent as the description proceeds in conjunction with the drawing in which:

Figure 1 is a side elevation of my dolly with both plates erect;

Figure 2 is an end elevation of Figure 1 taken in the direction of the arrow 2;

Figure 3 is a perspective view of the device as it appears in Figure 1; and

Figure 4 is a view showing how my dolly would be used in moving a wall.

Referring to the drawing for a more detailed description, it can be seen that my dolly embodies a platform H having an upstanding side plate l2 rigidly attached thereto. In accordance with the usual construction of dollies, the platform is equipped with a wide roller l3 suitably attached to the platform by plates H or in any other manner found convenient or desirable. Also mounted on the platform II is a plate l5 which is movable along the platform and is capable of swinging over the end of the platform and lying upon the floor in the position shown in Figure 2. The purpose of this construction is to provide a dolly whereby one of the side plates may be placed in an out-of-the-way position for loading and later may be adjustably fitted to the Wall thickness. The construction for this purpose consists of a pair of tongues IS on the plate [5 which are adapted to slidably extend beneath the platform I i so that the plate [5 ma be moved along the platform. On the end of the platform opposite plate I2, I provide a pair of hangers H which are arranged to engage and rotatably support the lugs It as the plate l5 reaches the end of platform H. The lugs l6 act as a hinge pintle for rotating the plate l5 around the end of the platform H so that it lays upon the floor as shown in Figure 2. In this position the wall is readily mounted upon the platform II and is placed against the plate l2. The plate l5 may then be moved up into an erect position against the wall and be attached to the wall by nails or any other suitable means which may be inserted through holes H! as provided. The plate l2 likewise may be equipped with holes l8 for the same purpose. When mounted in this manner, the dolly is secured to the wall and is prevented from turning under the wall or slipping along the edge of the wall. In practice, the dolly is generally placed somewher near the middle of the wall as shown at D under the wall W in Figure 4. Of course more than one dolly may be used if desired.

I claim:

1. A dolly comprising a platform having upstanding side plates, means for moving one of said plates along said platform to vary the distance between said plates, and means for swinging said movable plate over a side of said platform to an out-of-the-Way position for loading said dolly.

2. In a dolly having a platform with one fixed side plate, a second side plate slidably mounted on said platform for varying the distance between the two said plates, said second plate having lugs extending beneath said platform and slidably engaging the end margins thereof.

3. In a dolly having a platform with one fixed side plate, a second side plate slidably mounted onsaid platform for varying the distance between the two said plates, said second plate having lugs extending beneath said platform and slidably engaging the end margins thereof, and said platform having hangers on the underside thereof opposite said fixed plate for engaging said lugs and forminga pivotal point therefor.
