ATTORNEYS ietentetll lli l2,
To all ywhom i may consom:
Be it known that il, l .Dummies Min LER, a citizen of the Uniteil States, e
resident of Hennie, in the perish oi" Te?- relionne and State et Louisiane, lieve invented certain new une. useiiul lniieioifements in Hydraulic lllxpenilers "for Well Drills and tlie like, of which the 'following is e speeilieation.
My invention relates to improvements in Well drills and it consists in the construe- `tions, combinations and notie oti operation lierein described and claimed.
Anvoliject of the invention is provide auhzittaclinient to the drill stein, Wnicli o1.- eretes by hydraulic pressure toexpencl the drill bit.
. A further object et tlie invention is to lprovitle en attachment which operates on 'tlie principle stated. alcove, Wliicli can be used for expanding unfieri'eemers and tile like. y
A further object lof the invention is to provide e device for expanding tlie blades ot the drill bit Wliicli is actuated :fi-ud lieltl in the operative position by tlie force iinpressefl on tlie Water by the pump :it the top ot' the Well.
(,ltlier objects und advantages will up pour iu. tlie following speelt' Gatien, reference beinei lied to the accompanying; drawings, in which l Fig. 'l is e sectional View illustrating the general arrangement of :i flrill stern and 'oit liezul, showing tlie .i-ttoelunent in place loe tween the two,

Fig. fl is :i longitudinal section illustrating one application; of. the attachment to expand :in underrefuner, muil Fig. 5 is e similar View illustrating ouotliei opplicntiou oli tlio :ittziclin'lent to expand un. unrlerieuuior.
The purpose of ll Y .ie inif'outiou is 'to ex pend the lolzules l mul 3 of the drill bit in the liezitl 3 to the operative position, :mtl to liolfl them there. The mit 'olfitles ere et the consti-.notion disclosed in my copentlingr application for a potent on expansive tiri-ll bits, liletl. August 3, 192i., .Serial No.

But its use is not limit-eti. to tliis perticulai' purpose. lt muy be usedjin variety et' ivziys to expend the ports et en under remmer as illustrate@ in 4l unil The construction eon'ipiises e' section olf heavy pipe, clesignzitetl zilieve es the attzieliment Il. This pipe is threaded et et tlie upper end unil luis tapering thread (i et the lower end. The tlrill. stein screws into the upper enti, :intl tlie tapering tiiiezicl (i serews into the liit need 3.
According to tlie inode o operation ot' ille oit blades l' :intl 2- oic-tloe co-pentiing application :Illini/e retorted to, tlie blecles must lie lilted in respect to the bit heed 3 in ortler tluit tlicj/ may be expended inte tl'ie operiitive position. This is clone in the present insta-nce liy hydraulic pressure. Welter troni tile `pipe above enterstlie drill. siem i", passes around o. cylinder 8 flown to o. plug 9, up into the cylinder 8 Wliere it drives tlie piston l0 to tile top.

5. A well tool comprising a cylindrical bodya bit head having slots, means by which the head is attached to the. body, means forming a partition between the head and body but which has a wash hole establishing fluid communication between the two, blades carried by the bit head which are adapted to be contracted within ,the slots a cylinder, means by which it-is suspended at one end in the cylinderical body, means by which the otherwise free end of the cylinder is stabilized, a piston rod having operative engagement at one end with the blades and assing through the partition intosaid c lin er, and a piston carried by said: end o the rod adapted to be moved in the cylinder by fluid pressure to ekpand the blades out of said slots, some of said Afluid ypassing in a stream past the blades.
6. In a well tool, -a cylindrical body, a
' hydraulic cylinder, means by which said cylinder is suspended at one end in said body, means at the other endk forming stabilizing means to keep the cylinder from swinging, and a piston in said cylinder agijnst the motion of which said last means performs a stabilizing function.
7. A well tool comprisingl a cylindrical body, a hydraulic cylinder, means by which one end of the c linder is rigidly secured inside of the cylindrical body, a plurality of lugs radiating from the cylinder adjacent to the other end and contacting the mside of the body, and a piston which is operable in the cylinder and in respect to the operation of which said lugs have a stabilxzing function. y,
8.' In a well tool, a cylindrical body, a hydraulic cylinder situated in the body, means by which the cylinder is suspended 'at one end in the body said means having a passage for duid, a piston in the cylinder which is operable therein by virtue of the pressure of said fluid therea ainst, and means at the other and otherwlse free end of the cylinder adapted to stabilize the cylinder during the operation of the piston.
9. A well tool comprising a bit head having slots, blades. carried by the bit head, means in operative connection with the blades adapted to move them upward when -the pressure of a pump is imposed thereon in a well bore, and means on the bit head with which said blades engage in said upward movement expanding them in said slots in a cutting position.
10. A well tool comprising a bit head-having slots, blades carried by the bit head, a
hydraulic cylinder, a piston rod having engagement at one end with the blades the other end extending into the cylinder, a piston in the cylinder adapted to be'moved upward in respect to the well bore in which the tool is located by the fluid put under pressure Vby .a Pump, and means against A which the blades operate during such movement causing them to expand in said slots to va working position.
