PNEUMATIC DISPATCH SYSTEM

Application April 5, 1933, Serial No. 664,550

Claim. (Cl. 248—62)

This invention relates to an improvement in hangers by which conveyor elements, as for example transit tubes, conveyor frames, chutes and the like are supported when a system is installed.

Heretofore it has been the practice either to make the hangers of a definite length, usually either six or twelve feet, or else to make the hangers of the various lengths called for by the system to be installed. When the first procedure is 10 followed the operators installing the system must cut the hangers to the desired length on the job usually by means of hack saws, which results in a loss of time and a waste of material. The second procedure increases the expense and the 15 length of time involved in farbricating the hangers.

The primary object of this invention is to produce hangers of a definite length and to form therein weakened portions whereby the operators 20 when installing the system can quickly break them to the lengths required thus saving considerable time and eliminating the use of hack saws or other tools.

A further object of this invention is to pro25 duce hangers for transit tubes of pneumatic dispatch systems said hangers being known and designated in the trade as row clamps, such clamps comprising a plurality of tube receiving saddles separated by planar surfaces each surface being 30 provided with a hole and transverse notches extending at either side of the hole.

Other objects will appear from a consideration of the following description and of the drawing which forms a part thereof and in which

Fig. 1 is a side elevation of a row clamp type of hanger;

Fig. 2 is a view of a portion of a pneumatic dispatch system illustrating the suspension of tubes from a beam or ceiling by the use of row 40 clamps;

Fig. 3 is an enlarged side elevation of the portion of such row clamp illustrated in Fig. 2;

Fig. 4 is a plan view thereof; and

Fig. 5 is a side elevation of a supporting unit 45 for a conveyor section such unit comprising two hanger bars connected at the bottom by a cross bar on which the supported section rests.

The hanger elements are, as pointed out, made up in definite lengths and the portions necessary 50 for use at any point is broken off from such a length by the operator. Each length is provided with a series of notches to facilitate such breaking.

In Fig. 2 is shown a ceiling having a beam 10 55 to which the upper ends of rods 11 are secured.

The transit tubes 12 extend between the rods 11 and are fixed in place by clamps 15 secured to the rods 11. Each clamp 15 comprises a plurality of saddles 16 separated by planar flanges 17, each flange 17 having therein a hole 18 and a pair of transverse notches 19 which flank the hole 18, 5 and terminates in flanges 20 having holes 18 but no transverse notches.

When suspending the tubes 12, as shown in Fig. 2, the operator breaks off two clamp sections at the notches 19. Each section has two saddles in 10 which the tubes are clamped. The end flanges of the sections are secured to the rods 11 by nuts 21 and a bolt 22, passed through the connecting flanges 17, coacts with the nuts to clamp the tubes in place. 15

Under certain conditions the clamps are supported intermediate the ends, and in such installations end flanges may or may not be provided. It will be understood that the notches are of such dimensions that they will not materially weaken 20 the clamps. In place of providing the notches at one side only, as shown in full lines in the drawing, coacting notches may be provided in opposite sides of the clamps, as suggested by dotted lines in Fig. 3. 25

In the construction shown in Fig. 5 the hangers are in the form of straps 25 having a plurality of equally spaced holes 26 and transverse notches 27. The upper ends of the straps 25 are secured to the ceiling or other support by suitable means, 30 as, for example, brackets 28 connected to the straps by bolts 29 passed through holes 26, and the lower ends of the straps are connected by a crossbar 30 attached to the straps by bolts 31 through holes 26. The straps 25 are made of 35 standard dimensions and the operator, by means of the notches 27, is enabled to break off straps of approximately the lengths required.

While certain embodiments and uses of this invention have been shown and described, it will 40 be understood that I am not limited thereto and that other embodiments or uses may be made without departing from the spirit and scope of the invention as set forth in the following claim.
