REINHOLD H. WEBER, OF ATHENS, OHIO, ASSIGNOR TO THE JEFFREY MANUFACTURING COMPANY, A CORPORATION OF OHIO.
MINE-POST.
I Specicaton of Letters Patent.
Application led February 4, 1911.
.of Ohio, have invented certain new and useful improvements in Mine-Posts, of which the following is a specification, reference be ing had therein to the accompanying draw- 'gIhis invention relates to improvements in adjustable m-ine posts adapted for use 1n supporting t-he roof of a mine.
The object ofthe invention is to provide a strong, simple and cheap post of this character which is provided with means for adj ustment through a wide range.
In' the accompanying drawings, which form a part of, this specification, I have shown the form of construction which I now deem preferable. changes or modifications may be made with out departing from the spirit of my invention.
Of the drawings Figure l is a side elevation. Fig. 2 is a vertical cross sectional view. Fig.V 3 is a cross sectional plan view taken along the line 3 3 of Fig. 2.
Referring to the drawings, 1 and 2 represent the ltwo main elements of thev post, these elements being preferably tubular, with one telescoped within the other. The lower element 1 1s preferably larger, the upper element 2 being of a size adapted to permit itl to enter the element 1 with' a free working clearance. ,The ends of the elements land 2 are provided with flanges 3 and 4 which serve to give increased bearing surfaces for contact with the mine ioor Y and roof.- The out-er tubular element 1 is provided with a plurality of pairs of opposite alined apertures 5, 5 and 6, 6. Each of these apertures .is preferably rectangular, ledges 7, 7 being formed on the outer part of the element l at the bottoms of the apervture/s to provide increased bearing surfaces However, numerous,l
Serial No. 806,579.
The apertures -in the inner element 2 are differently spaced from those in the outer element 1.. As indicated, the distance between the apertures of the inner element is greater than that of the apertures of the outer element. However, so far as certain features of my invention are concerned, this relation may be reversed, with the greater distance between the apertures of the outer element.
10 represents a wedge adapted to extend through the apertures of both the outer element and the inner element. The upper surface of this wedge is beveled to have fiat c l Patented Dec. 10,1912.
engagement with the inclined top surfaces of the apertures of the inner element.
-11, l1 are filler blocks which are provided withdepending 1u s l2, l2, adapted to engage the edges of t e ledges 7, 7, or notches 13, 13, in a similar' filler block to prevent `endwise movement.
In operation, the vtwo maln elements of the post after being placed one within t-he other, are adjusted to approximately their final positions. Then the Wedge 10 is inserted through those apertures which are in properly related positions to permit the action of the wedge. 4After the wedge is inserted, it is driven in by a sledge to force the telescoping elements into firm and final engagement with the mine floor and ro-of. For certain positions no filler blocks are needed. For other positions, one may be necessary, and in still others, two. It will be apparent that on account of the differential spaclng of the apertures of the two' elements, the elements can be locked in any one of a wide range of relative positions.
It will be obvious that additional sets 0f apertures may be added if desired, the same differential spacing being n iaintained. Furthermore, my invention is not limited to two filler blocks as shown, as by properly proportioning the aperturesand the wedges and blofkaany desired number of blocks can be use While I have described my invention as an adjustable post for supporting mine' roofs, it will be obvious that it is not necessarily so limited, but may also be used as a support in various other connections, and also as a ack for heavy hoisting.
`lVhat'I claim is:
1. The combination in a device of the class described, of two telescoping elements each provided with a through d1ametrical a erture, a plurality of ller blocks adapte to be placedone upon another within the aper- V tures with one of them in engagement with the outer element, means for locking all'of the blocks against endwise movem'ent, and
described, of tvvo telescoping elements each Y provided with a through diametrical aperveo ture, aplurality of ller blocks adapted t0 vbe placed one upon another Within the apertures, each block having lugs adapted to engage either the outer element or another blockl to prevent endWise movement, and a Wedge adapted to be inserted through the apertures adjacent the blocks to forcibly move one of the said elements longitudinally relatively to the other.
3. The combination in a device of the character described, of two telescoping elements, a plurality of through diametrical apertures in each, the longitudinal spacin o the apertures of one element being ditferent from that of the other element, and means adapted toengage the edges of .any
set of apertures to cause the longitudinaly 4. The combinatlon 1n al device of the character described, of two elements one slidable relative to the other and each provided with a plurality of through diametrical'apertures, the apertures of one element being differently spaced longitudinally from those of the other, and a Wedgeadapted to be inserted through any set ofap'ertures of the two elements to forcibly move one of the said elements longitudinally relatively to the other.
5. The combination in a device of the character specified, of two elements, one slidable relative to the other, a' plurality of s aced ledges on one element, a plurality of dlfferently spaced ledges on the other, and means for engaging an ledge of one element and any ledge of t e other to lock one element against longitudinal movement relative to the other m one direction and to forcibly move it relatively to the other in the other direction. 1
