TUBULAR RACK Dec. 3, 1929.

Filed March 24, 1927 INVENTORA B JZ Z 5&7? Law- 15W ATTORNEY s' Patented Dec. 3, 1929 UNITED STATES ALBERT LAW, OF JACKSON HEIGHTS, NEW YORK TUBULAR RACK Application filed March 24, 1927.

This invention relates to a tubular rack suitable for supporting heavy cases containing book paper or other bulky articles and it is fundamentally designed to provide means for sliding the cases over antifriction devices carried by the rack.

An object of the invention is to provide a rack made entirely of iron pipe suitable for large warehouses which is permanently secured to the floor and can be multiplied into any required number of sections or alcoves merely by adding posts with rail connections.

Another object of the invention is to provide a tubular rack which can be readily assembled in the place where it is to be installed and in which the weight of the heavy case bears directly on tracks arranged on the horizontal rails and is transmitted to the tubular posts secured to the floor. 2 The invention resides more particularly in the novel combinations hereinafter described and claimed, reference being made to the accompanying drawing in which:

Fig. 1 represents a perspective view of a rack embodying this invention.

Fig. 2 is a horizontal section taken along the line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken along the line 3-3 of Fig. 2.

In the drawing is shown a rack constructed of a number of lengths of iron pipe and connected together by means of fittings. The rack includes a series of tubular posts 5 and series of tubular rails 6 coupled together at their ends by means of fittings 7 provided with threaded runs for engagement with the threaded ends of the posts and rails as is well known. The end of each lower post is screwed to a flanged plate 8 and fastened to the floor ofthe building. There are four upper, four lower posts, four upper and four lower rails shown in Fig. 1, so as to create a space or recess therebetween of any desired dimension to store a case or heavy trunk. Any number of sections can be added to the Serial No. 177,926.

height or length of the rack by screwing posts to vertical runs in the upper fittings or by spacing additional posts in a row and conmeeting the rails to horizontal runs in the fitting.

In order to easily slide a case in the rack apair of tracks in the shape of channel irons supported on the rails are provided. These channel irons 9 are equipped with antifriction devices such as rollers 10 mounted to revolve on a shaft 11 fixed in a block 12 secured by bolts 13 to the lower wall of the channel iron. This way of fastening the roller produces a strong and durable structure with the weight bearing on the roller equally distributed. It also permits the block to be removed when the roller becomes Worn and replaced by a new block at a trifling cost. The channel iron member is firmly secured to the rails by means of a bolt 14.- having one end hooked about the rail as indicated in Fig. 2 and the other end adj ustably secured to the bottom of the channel iron by a nut 15 engaging the threaded shank of the bolt. In this arrangement the weight of the case is transmitted directly onto the rails and thence to the posts. It will be seen, that by means of the hooked bolts the channel members 9 can be readily loosened merely by adjusting the nuts 15, and the channel members can he slid along the rails 6 to fit cases of different widths inthe space between the rails and posts.

I claim:

1. A rack comprising a series of posts, rails connected to the posts, channelled track members arranged to bear on the rails, rollers mounted in blocks rernovably attached to the bottom wall of the channel member, and clamping devices for securing each end of the channelled member to the rails, each device including a bolt having a threaded Stem adjustably connected to the bottom wall of the channel member with a hook to clasp the rail.

2. A rack comprising a series of posts, front rear and side rails connected to the posts, channelled track members arranged to rest on the front and rear rail, rollers mounted on the track members, and bolts, each having a threaded stem projecting through a hole in the bottom Wall of the channel member With a nut coacting with the thread, the loWer portion of the respective stems engaging the front and rear rail for immovably fastening both ends of the track members to the front and rear rails.

In testimony whereof I have hereunto set my hand.

ALBERT LAWV.
