Our invention relates to improvements in radiator fasteners, and particularly to that class of fasteners which is designed to be used in conjunction with a hanger, to hold the upper end of a wall radiator against the hanger.

The fastener commonly used for this purpose is a bolt, which is adapted to beinserted between the tubes or sections of a radiator from the front (or side most distant from the wall) and has a lug formed to engage the tubes on its outer end and a nut to hold the inner end of the bolt in the radiator hanger.

These fasteners when used with two, three or four column radiators are cumbersome and conspicuous.

It is our object to obviate these objections and to provide an ehicient and inconspicuous radiator fastener which is inexpensive to manufacture and easy to apply.

The drawings, forming a part of this specilication, illustrate what we at present believe to be the best form of our device but it will be readily understood that modifications are possible within the spirit of our invention.

Referring to the accompanying drawings, Figure 1 is an elevation of our device showing the fastener in a suitable hanger, a radiator being in position on the hanger and the hanger secured, in the usual manner, to the wall; Fig. 2 is a detail perspective view of the preferred form of our fastener, the bearing plate being shown in the normal or right angle position with respect to the bolt; Fig. 3 is a detail side view of the same with the bearing plate in vertical section and in normal position, the position for insertion between the sections of a radiator being shown in dotted lines and Fig. 4 is a horizontal section through a radiator, illustrating the method of inserting the bolt and bearing plate between tubes of the radiator.

Our device consists generally of a bolt 1-0 formed with a threaded end 11 and head 12 and provided with a bearing plate 13 having a slot 14 through which said bolt passes. The plate 13 in our preferred form is shaped like a disc with a flattened side 15. The bolt 10 is held in an eccentric position in the slot Serial No. 76,400.

14: by means of a tongue 1%, so that the plate will naturally be suspended with its curved or heavier side down as shown in Fig. 2. This tongue 1 f preferably consists of an outwardly bent strip of metal which is attached to the plate at the lower extremity of the slot 14. The slot 14, as will be readily understood, permits the disc 13 to be collapsed or closed upon the bolt 10 so as to make a small acute angle with the axis of said bolt, as shown in Fig. 4%, and when so collapsed the tongue 14 extends along a side of the bolt.

The end 11 of the bolt 10, as shown in Figure 1, is adapted to be inserted through a perforation in the frame 18 of a suitable radiator hanger and a nut 19 is screwed on the end 11 within the frame 18. The latter frame is designed to be secured to a wall by means of an anchor bolt 20 and a vertical rod 21 is suspended from a nut 22 within the frame 18. A bracket 23 is supported on the lower end of the rod 21 and an off-set block 2st is slidable on said rod above said bracket to hold the lower end of the radiator away from the wall. A triple column radiator is indicated by the numeral 25 in Figure 1.

In mounting a radiator with our device the connecting tube 26, between sections of a radiator, is placed so as to be supported on the bracket 23 and the bolt 10 with the washerlike plate 13 collapsed, as shown in Figs. 3 and 4:, is inserted between adjacent sections of the radiator. The bolt 10 is inserted far enough to permit the plate 13 to turn, within the space between columns of the radiator, to the right angle position shown in Figures 1 and d. The flattened edge 15, of the plate 13, facilitates this turning from the collapsed to the right angle position and the greater weight of the opposite edge of said plate causes the plate to turn on the bolt 10 until the edge 15 is up, thus bringing the greatest diameter of said plate transverse the vertical opening between sections of theradiator. When the plate 13 has fallen to vertical position, the bolt 10 may be retracted so that the head 12, engaging the plate 13 brings said plate in contact with the adjacent tubes of the radiator. The threaded end 11 is finally inserted in the frame 18 and the nut 19 placed on the end and tightened to fasten the upper end of the radiator hanger against the frame 18.

It will be noted that the tongue 14* in- 5 sures final. positioning of the plate 13 with the bolt in the proper end of the slot 1- so that the pull of the radiator is balanced across the greatest diameter of the plate on exactly opposite sides of the head 12. The

10 washer-like plate of this invention is always concealed within the central space of the radiator and there is no possibility of the radiator escaping from the fastener, even if the nut should become loose on the bolt 10.

15 Our fastener has the further advantage of being unusually simple and inexpensive.

Having described our invention what we claim as new and desire to protect by Letters Patent is:

m 1. In a fastener, the combination with a normally horizontal bolt, adapted to be secured at one end in a support, a wide plate formed to hang freely on said bolt in a plane perpendicular thereto and normally held by I gravity to project horizontally on opposite sides of said bolt in engagement with horizontally spaced, vertical columns of a radiator, said plate being formed with a long and relatively narrow slot cut therefrom to "receive said bolt and permit tilting of said plate at an acute angle with said bolt and means projecting from said plate at an end of said slot, adapted to maintain said bolt in the opposite end of said slot when the plate is perpendicular to said bolt.

2. A radiator fastener comprising, a normally horizontal bolt adapted to be secured at one end in a hanger, a washer-like plate formed to hang freely on said bolt in a plane perpendicular thereto, and having portions adapted to normally project horizontallyat both sides of the bolt to engage substantially vertical columns of a radiator, said plate being formed with a long and narrow opening for said bolt to permit tilting of said plate at an acute angle with said bolt, to thereby permit insertion of the plate between said columns, and a tongue projecting from an end of said opening, obliquely at one side of the 59 plate, said tongue being arranged to maintain the bolt in predetermined position in said opening when the plate is perpendicular to the bolt.

In testimony whereof, we have hereunto subscribed our names to this specification.
