May 20, 1930. J. B. WEBB OVERHEAD CONVEYER Filed Oct. 1'7, 1928 ATTORNEYS Patented May 20, 1930 =--P-AT'ENT OFFICE JEBVIS IB. WEBB, OF DETROIT, MICHIGAN A OVERHEAD CONVEYER The present invention relates to overhead conveyors and particularly to track construction therefor.

Among the objects of the invention is to provide novel means for connecting abutting ends of track rail sections.

Another object is connecting means so constructed and arranged as to also form a par ticularly efiicient hanger attaching means. Other objects will readily occur to those skilled in the art upon reference to the following description and the accompanying drawing, in w h Fig. 1 is an end elevation of the device. Fig. 2 is a side elevation thereof. Fig. 3 is a to plan view, and

Fig. 4 is a en arged section on line 4-4 of is indicated in. the drawings the device comprises a pair of indentical plates each having a vertical web 10 and-a horizontal web 20 disposed at the lower edge of the vertical web. The web 10 is provided with suitable openings for the passage of bolts 11 and at one end near the top edge with a short longitudinal rib 12 on the face 0 posite the webs 20.

The webs 20 are pre erably not coextensive with web 10 but extend toward each other from the ends of web 10 for a distance equal to about the length of a rib 12. These webs 20 are turned downwardly and backwardly at an angle as at 21, so that a section through this edge shows a hook-like formatlon, and within the hook 23 the metal is formed so that small low ribs 22 extend across the hook, two or more of such ribs 22 being preferably provided. r

As indicated in Figs. land 2 a pair of the plates is used to grip the upper flanges of an I-beam 31 forming the conveyer track and preferably arranged to grip abutting ends 31' and 31" of adjacent sections of said track. The device may be sufliciently rigid to be used only for the purpose of such connections but is also intended for use as a track hanger, the bolts 11, beside acting as clamping means, also serving to secure t to angle irons or other suitable bracket mem-'-' bers such as are diagrammatically shown in Figs. 1 and 2.

e assembly across said hooks.

Application. filed October 17, 1928. Serial No. 312,951.

In applying the device to a track, the ribs 12 act as fulcrums and cause the hooks 23 to be drawn toward each other by the bolts 11,

sufiicient pressure being exerted to cause the to be limited, not to the specific details herein set forth but only by the scope of the claims which follow.

What Iclaim is I 1. A connecting device for conveyer tracks comprising a pair of lates each having a horizontally extending liooked portion and a verticallyextending 1 portion rovided with a fulcrum, and means locate between said hooked portion and fulcrum for drawing said plates together. 2. A connecting device for conveyer tracks comprisin a pair of plates each having a horizontal y extending hooked portion and a vertically extending perforated web with a rib above said perforations and extending in a direction opposite to that of the hooked portion, and means for drawing said plates together.

3. A connecting device for conveyer tracks comprising a pair of plates each having horizontally extending webs the extreme edges of which are turned down and backwardly at an angle to form a hook, and a vertical web provided at one. end with a rib located on the face opposite said first web, and clamping means between said rib and said first web.

4. A connecting device for conveyer tracks I comprising a pair of plates each having horizontally extending webs the extreme edges of which are turned down and backwardly at an angle .to form a hook, and a vertical web provided at one end with a rib located on the face opposite said first web, and clamping means between said rib and said first web, there being short ribs within and extending 5. A connecting device for conveyer tracks comprising a pair of plates each having a horizontally extending hooked portion and a.

a fulcrum, and means locate hooked rovided with between said portion and fulcrum for drawing said plates together, means being provided to prevent relative longitudinal movement between said device and said tracks.
