UNHTED STATES.
CHARLES DRAKE, OF MNNINGTQN, W115i. VIRGINIA.
DERRICK.
Application filed June 2,
To all whom it may concern."
Be'it known that I, CHARLES -DRAKE, a citizen of the United States, and a resident of Mannington, in the county of Marion and State of West Virginia, have invented a new and useful Improvement in a D'errick, of which the following is a full, clear, and exact description.
My invention relates to derricks and more particularly to the supporting frames therefor, my more particular pur ose being to provide a frame having re atively great strength and made up of arts easily and cheaply produced and stan ardized.
Reference is made to the accompanying drawings forming a part of this specification and in which like reference characters indicate like parts throughout the several figures.
Figure 1 is a fragmentary front elevation of the improvement.
Figure 2 is a horizontal cross section through one of the legs of the derrick and parts immediately associated therewith taken immediately above the bolt.
Figure 3 is a erspective view of one of the parts shown in Figure 2.
F1gure 4 shows another form of my device.
A derrick frame is shown in Figure 1 provided with corner posts or le s 5, each made ofan angle iron, as may e understood from Figures 2 and 4.
A clamp 13, having the formof an angle piece is fitted upon the outside of each leg5. An extra reinforcing leg 16 extends from bottom to top of the tower. A skeleton plate 17 having one or more pairs of ribs 18, 19 and 20 integral with it and bent to difi'erent angles, 'as indicated in Figure 3, is placed within the angle leg 5 and the leg 16. A curved bolt 21, provided with a head 22 and a nut 23, extends through a hole 24 in the skeleton plate 17', and also through holes in the clamp 13. When the nut 23 is tightened, so as to place the bolt under tension, the skeleton late 17 is forced tightly toward the ange leg 5, so that the various ribs 18, 19' and 20 are jammed tightly against difierent portions of this angle leg. Thus a very secure joint is made and the brace thus arranged has considerable strength. In the event that the reinforcing plate 16 is omitted or of less thickness than that illustrated, the bolt 21 is extended through an opening 24* to hold 1921. Serial No. $14,336.
the skeleton plate in position against the leg 5. Braces 14 are secured to the clamp 13, as indicated in Figure 1. Struts 15 are also secured to the clamp, being held in position by the curved bolts 21, as shown in Figure 2.
In case the skeleton plate shown in Figure 3 is not rigid'enough for the purpose in-' tended, I use in its place" the member 38 shown in Figure. 4..
i In the form shown in Figure 4, the derrick leg appears at 25, and has as before the form of an angle iron. The clamp is shown at 26 and has a form of an angle plate, provided with holes 27. Another an le leg member 37 is arranged on the inner face of the leg 5 to reinforce the same. The member 37 extends from the bottom to the 'top of the derrick. The clamping plate 38 has in cross section a substantially arcuate form,
radially inward engaging the reinforcing leg 37. The leg 25 is provided with holes into which lugs 31 may extend for preventing relative displacement of the leg 25 and the clamp 26. A curved bolt 33, provided with a head 34 and a nut 35, extends through the holes 27 and also through holes in the braces or struts which are shown at 36.
The curved portion of the clamping plate 38 is preferably grooved as shown to receive the bolt 33. The reinforcing leg 37 serves the double purposeof leg and clamp and it may be made up of lengths of angle iron.
In the construction above described the various reinforcing members may be added without tearing down any portion of the original structure and without materially changing the same.
If desirable, the said bolts may be threaded at both ends and nuts turned thereon" instead of a solid head at one end.
I do not limit myself to the precise construction shown, as variations may be made therefrom without departing from the spirit of my invention.
Having thus described my invention what I desire to secure by Letters Patent is as follows 1. A device of the character described and being in the form of an angle iron, a
plate provided with ribs engaging the inner surface of said reinforcing leg and a bolt extending through said clamp and plate provided with a nut.
3. A device of the character describedcomprising a supporting leg having a general form of an angle iron,a clamp mounted upon saidsup porting leg and likewise having the form of an angle plate fitted on the outside of said angle iron, an angular. reinforcing leg fitting in the supporting leg, a'skeleton plate provided With ribs engaging the inner surface of said reinforcing leg and a curved bolt extending through said clamp and through said skeleton plate so as to force said clamp and said skeleton plate in opposite directions againstthe opposite faces of said plate.
4. A device of the character described comprising an angular supporting leg, a
correspondingly shaped reinforcing leg fit ting in the supporting leg, an angular clamp fitting on the supporting leg, a member engaging the inner face of'the re-inforoing leg, and a bolt passing through the clamp and engaging the said member.
' 5. A device of the character described comprising a supporting leg having a general form of an angle iron, a clamp mounted uponsaid supporting le and likewise having-the form' of an angle iron, said clamp being fitted'on the outside of said angle iron first named, a reinforcing leg of angle iron within the supporting leg, a skeleton plate provided with r1bs engagmg the inner suropposite faces of the reinforcing leg of angle iron. 1 I 6.'A device of the character described comprising a supporting leg consisting of a plurality of sections secured end to end, eachsection having the form of an angle iron, a clamping plate fitted into said leg, another clampin plate fitted outside of said leg and secure thereto, a clamping and bracingmember' within said first mentioned clamping plate and engaging the crotch of the angle and the sides thereof and a bolt engaging said clamping and bracing member and extending through said second mentioned clamping plate, said bolt being adapted for connection of struts or girtsthereto. 7. A device of the character described comprising a supporting leg having the form of an angle plate, a clamp mounted on said supporting leg and likewise having the form of an angle plate, said clamp being fitted on the outside'of said supporting leg, a reinforcing leg within the supporting leg, a skeleton plate provided with ribs engaging the inner surface of said reinforcing leg and an intermediate portion engaging the crotch of the angle of said leg, said skeleton plate having portions bent in angular relation to each other and intermediately left straight, the bent portions engaging the sides of said reinforcing legs at the inner faces thereof, and a clamping member connecting the sides of the clamp and skeleton plate and ada ted for the connection of bracing means t ereto outwardly of the clamp.
