POLE-SUPPORT.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application led February 21, 1917. SeriaI No. 150,239.

To all whom t may concern:

Be it known that I, I-IAzEL BURTON BUSH,

a citizen of the United States, residing at Redlands, in the county of SanBernardino, State of California, have invented a new and useful Pole-Support; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artY to which it appertains to make and use the same.

This invention relates to a new and useful support for various kinds of poles, such as telegraph andtelephone poles, and the like.

One of the objects of the invention is to provide an improved support or prop to support the pole at different times, alternating with the pole erecters attaining new holds on the pole, in order to gradually stand the pole onits end and in its foundation.

A further object of the invention is to provide a support which is simple, efficient and practical in construction, and which may be manufactured very cheaply, and will serve advantageously to obtain the desired result, without collapsing under the weight of the pole.

A further object is to provide a support of this kind comprising two crossing members or legs, so pivoted together at their point of intersection as to permit the legs to be collapsed together when the support is not in use.

A further object of the invention is to provide a pole supporting means or brace detachably connecting the upper ends of thetwo members or legs, and a brace pivotally carried by one leg and designed to detachably engage means on the other leg, to prevent collapsing of the legs.

A further object of the invention is to provide feet for the legs or members.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprisesfurther features and combination of parts, asfhereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a View in perspective of the improved support, showing the same in use.

Fig. 2 is a view in elevation of the support.

Fig. 3 is a view of the upper end portions of the intersecting or crossing members, showing parts in section, and illustrating the pole engaging member partly in elevation and partly in section.

Fig. 4, is a.l sectional view on line L -4 of Fig. 3.

Fig. 5 is a detail view of the detachable connection ofthe lower brace.

Referring more especially to the drawings, 1 and 2 designate two intersecting members, which, at their point of intersection are connected by the pivot ,pin 3. These members consist of angle bars, Vand which are reversely disposed. The upper ends'of said members or bars are provided with bifurcations 4, which are formed inthe lateral flanges. Extending laterally from the upper ends of the bars, adjoining said bifurcations are headed pins 5. `When the bars or Vinembers are erect, as shown in Fig. 1, a curved bar 6 is utilized. Each end of this bar 6 has an L-shaped slot 7 The slots of both ends of the bar 6 are designed to engage the pins 5, thereby bracing the upper ends of the members or bars 1 and 2. A pole engaging plate 8 is provided. This plate 8 is U-shaped in cross section, in order to arch the bar 6, there being suitable insulation 9 in the U- part of the plate 8, thereby insulating the plate 8 from the bar 6. This plate 8 in elevation is curved to substantially conform to the cross sectional contour of the pole to be erected, and is riveted, as shown at 10, to the bar 6. The upper curved edge of the plate 8 is provided with sharp points 11 and 12, to pierce the pole, thereby preventing slipping of the support yas well as thepole. The rivets 10, where they pass through the bar 6 and the opposite walls of the U-portion of the plate 8, are also insulated, as shown at 13. By virtue of the insulation, current is prevented from being transmitted to the members or bars 2 and 3, should the pole be damp, and have live wires connected thereto, and should the pole be constructed of metal.

Connected to the member or bar 2 by means of a pivot pin 14, is a brace 15. This brace, at its other end, has a notch 16 in its upper edge portion to engage the headed pin 172L of the member 1, there being a leaf spring 17 secured at 18 to the bar or member 1, whereby the upper end edge of said leaf spring will engage the brace 15 and hold its notch in engagement with the headed pin, thereby bracing the lower portions of the members or bars 1 and 2. The lower portions of the bars 1 and 2 constitute legs, and

secured to the lower ends of the bars or members 1 and 2 are feet 19. Each foot consists of Va wood insert block 20 secured to one oi the flanges of each leg by means of the screws 2] and 22, and also secured about the lower ends of the foot or wood blocks by means of the screw 22 is a metal wear strap or plate 23. One end of this strap engages 4between the block and one flange oi? the bar or member. A suitable leather strap 211 is riveted at 25 to the bar o-r member 2 and has a buckle 26 whereby the two members or bars 1 and 2 may be clamped together, when` what Copies of this patent may be obtained for furcations, a curved bar engaging said bifurcations and having L-sh'aped slots at its ends detachably' engaging said headed pins, a

pole engaging plate curved concentric with the bar and being U-shaped in cross section and straddling said bar, insulating means between the bar and the walls of the U- shaped portion of said pole engaging plate, means passing through the-U-shaped portion and the bar to hold the plate thereto, said pole engaging plate hfwing an upstanding part to engage the pole, and means tobrace said members at a point below their intersection. o

In testimony whereof I have signed my name to this specification inthe presence ot two subscribing Witnesses.
