AUGUST WINZ, OF Rll'TTENSCI-IEID, NEAR ESSEN-ON-THE-RUHR, GERMANY.
PROP FOR MINES.
Specification of Letters Patent.
Patented Oct. 1'7, 1911.
Application filed May 24, 1910. Serial No. 563,056.
To all whom it may concern:
Be it known that I, AUoUs'r VVINz, a subject of the German Emperor, and residing at Ruttenscheid, near Essen-on-the- Ruhr, Germany, have invented certain new and useful Improvements in Props for Mines, of which the following is a specification.
My invention relates to composite props for mines and a primary object is to provide a flexible prop in which the vertical pressure is converted by a sliding shackle and slanting faces into transversely-acting tension and is taken up in this form by elastic insertions.
According to my invention the prop comprises a top part and a support made of figured iron, 6. g. an old railway rail or the like, slanting faces being provided in the bottom part of the prop, z. e. the support, the top part engaging over the bottom. The sliding faces are made by cutting away material some distance from the top end of the support so that the end of the support which is located above them and retains its full section can serve as a guide to the cap. The shackle is first placed in such manner around the support that it is situated at the top of the slanting faces, and the bolts, which have elastic washers, are screwed tight. The box-shaped top part is guided by the head of the support and rests loose on the shackle, so that the latter is pressed on the tapered portion of the support by the increasing pressure of the roof. Therefore the shackle must expand and compresses the elastic intermediate members.
My invention is represented by way of example in the accompanying drawing, where- 1n:
Figure 1 is a longitudinal section, Fig. 2 is a side elevation, and Figs. 3 and 4 are cross-sections showing my improved prop, Fig. 3 being a section through the top part and Fig. 4 a section through the shackle, and Fig. 5 shows a member placed on the web of the support for producing broader, slanting faces.
Referring to the drawing, a designates the support or bottom part of the prop consisting of an I-girder, slanting faces 6 and 0 being cut in the flanges for the shackle d. The shackle is held together by the bolts 6 and f having elastic washers g and it, respectively. Preferably the nuts have washers of semi-circular cross-section. The top part 2' preferably has the shape of a box. It is guided by the head 7:: of the support and provided in its sides with slots Z which enable the prop to be observed.
Fig. 5 shows a member m having slanting faces corresponding to the faces Z), c placed over the web of the support a, so that the shackle may slide on broader slanting faces.
1 claim 1. A prop for mines, comprising a support having a head and slanting faces in the flanges thereof below said head, a shackle clasping the support at the slanting faces, and a top-part supported on said shackle.
2. A prop for mines, comprising an L shaped support having a head and slanting faces cut in the flanges below said head, a shackle clasping the support at the slanting faces, and a toppart, guided on the head of the support and supported on the shackle.
3. A prop for mines, comprising an upright support having a head and slanting faces below said head, a shackle having bolts with elastic washers applied to the slanting faces of the support, and a toppart supported on the shackle.
4. A prop for mines, comprising an I- shaped support having a head and slanting faces cut in the flanges thereof, a member having slanting faces corresponding to the faces of the support and placed over the web of the girder, a shackle clasping the support at the slanting faces, and a toppart supported on said shackle.
