Patented May 7, 1907.
Application filed November 12,1906. Serial No. 342,949.
To all whom/ it may concern:
This invention relates to theseparators' employed for iron girders.
The separators in common use consist of properly spacing the beams of cast-iron plates having integral lugs for the bot-enga of the tie bolt for retaining the separator in beams, consisting of a platehaving an inte- 11 passage-of the bolts which tie the beams to-. Such separators have the objection gether. that their lugs are liable to be broken off in shipment. They are also subject to variations due to shrinkage of the metal, and when this is the case they fit loosely between the beams and do not properly transmit the superposed load from one beam to the other.
The object of my invention is the .provision of a light and inexpensive separator which will accurately fit the beams so as to evenly distribute the load and which possesses the necessary strength to resist breakage of its bolt-receiying member or attachment under the rough usage to which such articles are subjected.
In the accompanying drawings: Figure 1 is a cross section of an I-beam girder pro-.
vided with the improved separator. Fig. 2 is a horizontal section in line 22, Fig. 1. Fig. 3 is a perspective view of the separator. Figs. 4 and 5 are similar views of modified constructions of the same.
Similar letters of reference indicate corre: sponding parts throughout the several views.
The girder illustrated in the drawings'is c'ornposedof a pair of parallel I-beams A tied together at suitable intervals by the usual bolts, one of which is shown at B, but the invention is equally useful in connection with girders consisting partly or wholly of channel or other beams.
Referring to Figs. 1,2 and 3, C indicates the separator whlch consists of a pressed. steel plate of suitable thickness and of the proper outline to closely fit the webs and flanges. of the opposing beams, as shown in Fi 1. This plate is provided with seats or ing portions formed integral therewith and bent or pressed out of the general plane thereof in opposite directions, so that the seats receive and embraceopposite sides place. In the construction shown in Figs. 1, 2 and 3, the plate is provided centrally with a semi-circular horizontal loop d which em braces one side of the tie bolt and is pressed up from one side of the plate, and on 0 posite sides of said loop .with semi-circular ori zontal seats or grooves e which" embrace the other side of the bolt and are formed by pressing up the opposite side of the plate, forming three bearing points or surfaces for the bolt. As is evident from an inspection of the drawings, two parallel upright slits are formed in the separator before pressing up said loop and seats The metal forming these parts is not stretched, but .is simply bent or pressed. in opposite directions without' drawing it or reducing its thickness, the pressing operation shortening'the separator blank to the extent that itsmiddle portion is bent or deflected to form the loop at and the seats e. -..l.he' metaltherefore retains its original strength and toughness and the loop is not liable to be fractured in pressing the blank or to be broken by rough handling or in shipment. In addition to this important advantage, the separator is comparatively light, it can be cheaply produced, and being formed of sheet steel, it can be accurately cut to snugly it the beams of the girders, thus reliably transmitting the load from one beam to the other and evenly distributing it.
The arrangement of the bolt-seats of the separator may be modified without departing from the essence of the invention. Fig. 4, for example, shows a modification inwhich .the central loop dof the first-described construction is omitted and the separator plate C is provided on opposite sides of a central slit with boltseats-c extending fronrthc slit to' the lateral edges of the plate and pressed outwardly in opposite directions, forming two bearings forthe bolt.
Fig. 5 shows another modification similar to that illustrated in Fig. 4 but differing therefrom in that the plate C has a comparatively large central opening f which separates the oppositely-prcssed bolt-seats 6 The separatorshown inthe drawings has a single set of bolt-seats, butit may obviously have two or more sets for receiving a corresponding number of tie-bolts according to the h ight of the girder.
' claim as my invention:
, 1-. A pressed-metal-separator for girdergral attaching member bent up from the side thereof and constructed to embrace a tiethe side thereof in opposite directions, substantially as set fort bolt of the beams, substantially as set forth.
2. A pressed-metal separator for girderbeams, consisting of a plate having integral bolt-embracing seats pressed outward from 3. A pressed-1netal separator for girderbeams, consisting of a plate provided with integral bolt-embracing seats pressed outward beyond the sides thereof in opposite directions and having the same thickness as I the plate, substantially as set forth.
4,. A pressed-metal separator for girderbeams, consisting of a plate provided on one side with a boltvembracing loop and on its other side with bolt-embracing .seats arranged on opposite sides of the loop, said loop and seats being integral with the plate and pressed outward therefrom in opposite directions, substantially as set forth.-
