Specification of Letters Patent.

Patented Aug. 4., 1914..

, Application filed August 12, 1912. Serial No. 714,636.

To all whom it may concern Be it known that I,.Bnoonn1on HASKELL, a citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Telegraph- Poles and the like, of which the following is a specification.

The present invention has to do with the construction of metallic poles designed especially for telegraphs or otheroverhead wire supports, and particularly to a type of such pole wherein a series of upright legs are held inproper spaced apart relation by a series of transverse bands secured thereto at proper intervals.

The matters of invention in the present instancerelate to a constructlonwhereby I1 ples of my invention; Fig. 2 is a transverse sectionon an enlarged scale, the same showing a transverseband and locking devices in elevation; Fig. 3 is a section on line 2-2 of Fig. 2; Fig. 4 is an enlarged plan View of the locking devices and corner of transverse band; Fig. 5 represents a perspective view of several elements comprising means for locking uprights to the transverse bands; and Fig. 6 is a section similar to that of Fig. 2 of a modification of the transverse band.

The uprights or longitudinal members 1 are preferably four in number and as shown are formed into L-shape in cross section from bar stock. The transverse bands 2 i are likewise formed of plate or sheet material of suitable Width and preferably square, as shown, and are provided with pockets at the corners to receive the uprights 1. These pockets may be formed from the stock of the band itself and proper straps 3 may be employed to close the mouths of said pockets. The transverse bands how ever, instead of being continuous, may be made of two U-shaped sectionsQ, and 2 held together by riveting the V-shaped straps 3*.and 3 as shown in Fig. 6. The straps 3 and 5 in this casenot only form the innerside ofthe corner pockets but at the same time means for. securely binding the sections of thetransverse bands and thus avoids welding without increasing. the number of rivets.

The, manner of securely lockingand fastening the uprights to the transverscbands is effected as follows: Each of the transverse bands is provided at each side and near the corners with a recess or depression 4, extending outwardly. Filling blocks 5 and 6 are fashioned to substantially fill the aforesaid corner pockets, the same having in their abutting faces complementary portions of a recess 7, to receive a wedge block 8,which is inserted so as to exert its principal Wedging action in separating the blocks and pressing the same against the sides of the uprights 1. Theinncr sides of said wedging blocks 5 and 6 are formed with a wedg'ing bulge 9 which, as will be clear when the blocks are forced home, coact with the strap 3, and cause the bulge sections 9, 9, to force the corresponding sections of the upright 1 into the recesses or depressions 4: of the transverse bands,as shown in Figs. 3 and 4.

The filler blocks may be made as shown, so as to slightly taper from the top to bottom in. order to rest in the corner pockets against the inner side of straps 3, as shown in Fig. 4.

From the foregoing disclosure it Will be seen that I have provided means whereby the uprights and transverse bands are strongly and effectively clamped together by a few parts, and. the same can be readily assembled or disconnected without :destroying their ability to be used over again.

While I have shown the sections comprising the transverse bands and straps as riveted together, any otherexpedient could be used as bolting or welding.

What I claim is 1. A knockdown pole comprising up rights, transverse bands having pockets to receive said uprights, said bands havingrecesses or depressions extending outwardly at their pocket sections, straps secured to said bands adjacent said pockets, plural r'e movable filling members for each pocket having permanent bulged sections orprojections corresponding to the recesses or depressions in the bands, and removablemeans to expand the filling members.

2. A knock down pole comprising up- I their pocket sections,- straps secured to said bands adjacent said pockets, ,tWo' removable filling members for each pocket, each havingj a permanent-bulged section or projection corresponding to the recessor depression in. the bands, and-a removable Wedge to expand the filling members. v

3. A knockdown po1e=- comprising upright's, transverse bands each of Which'con- 'sists of two angular shaped pieces forming inner pockets to receive uprights and hands, and means abutting against said uphaving their free ends adjacent each other, tWo angular shaped straps'on the inner sides of thetransverse bands with the free ends of said straps adjacent each other, and connected to the center sections of said bands and the; center sections of the straps connected to the free ends of the transverse rights and straps for holding said uprights in the pockets of the band's 1 In testimony whereof. I aflix my signature in presence of two Witnesses BRoDERioK HASKELL Vitnes'ses:
