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 rst procedure is 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 length of time involved in farbricating the hangers.
The primary object of .this invention is to produce hangers of a denite lengthand to form therein weakened portions whereby the operators 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 produce 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 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 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; andv Fig. 5 is a side elevation of a supporting unit 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 denite lengths and the portions necessary 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 break- In Fig. 2 is shown a ceiling having a beam I0 to which the upper ends of rods II are secured. The transit tubes I2 extend between the rods II and are fixed in place by clamps I5 secured to the rods I I. Each clamp I 5 comprises a plurality of saddles I6 separated by planar flanges I1, each ange I'I having therein a hole I8 and a pair of transverse notches I9 which flank the hole I8, and terminates in iianges 20 having holes I8 but no transverse notches.
When suspending the tubes I 2, as shown in Fig. 2, the operator breaks oiI two clamp sections at the notches I9. rEach section has two saddles in which the tubes are clamped. The end anges of the sections are secured to the rods II by nuts 2| and a bolt 22, passed through the connecting flanges I1, coacts with the nuts to clamp the tubes in place.
Under certain conditions the clamps are supported intermediate the ends, and in such installat-ions end anges may or may not be provided. It will be understood that the notches are of such dimensions that they will not materially weaken the clamps. In place of providing the notches at straps by bolts 29 passed through holes 26, and t the lower ends of the straps are connected by a crossbar 30 attached to the straps by bolts 3| through holes 26. The straps 25 are made of standard dimensions and the operator, by means of the notches 21, is enabled to break ofi straps of approximately the lengths required.
While certain embodiments and uses of this invention have been shown and described, it will 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.
In a pneumatic dispatch system, clamps for transit tubes, each clamp comprising a plurality of tube receiving saddles, and planar flanges separating said saddles, each flange having a pair of transverse notches therein and a hole between the notches whereby the clamp may be easily broken at any notchto furnish a length having any desired number of tube receiving saddles and flanges with holes therein.
