applicati@ med May 2o, 1907. seran No. 374,625.
To all 'whom 'it may concer/n:
Be it known that I, ALFRED CoLLING- WOOD, residing at Franklin, in the county of Venango and State of Pennsylvania, have 'invented certain new and usefulv Improvements in Oil\\"ell Packers, of which the following is a specification.
` My invention relates to certain new and useful improvements in oil well packers and the like, and is particularly designed for the purpose of shutting off water in the oil or any place in the well hole where 'the water may enter.
The invention also has for its object to provide a packer immediately above and immediatelybelow the point of entry of the water so as to save the use of the pipe or casing from the top of the packer to the surface of the earth.
In its generic nature, the invention embodies an improved form of packer adapted to be expanded to tightly embrace the walls of the Well and form a seal at such point.
In its more subordinate nature the invention embodies certain novel details of construction, combination and arrangement of parts, all of which will be first described in detail, and then be specifically pointed ont in the-appended claims, reference being had to the accompanying drawings. in which Figure 1, is a diagrammatic side elevation of my invention, showing the same applied for use, the well being shown in section. Fig. 2, is a central, vertical longitudinal section similar to Fig. 1, showing the position of the parts prior to having the acker expanded to tightly engage the sur ace of the well aperture. Fig. 3, is a similar View showing the packer expanded. Fig. 4, is a section on the line 44 of Fig. 3.
Referring now to the accompanying drawings in which like numerals and letters of reference indicate like arts in all of the figures it will be noticed t at 1 represents a casing which is of such length as to suit the requirements of the oil well 'and the casing 1 has its ends threaded at 1a and 1b to receive the collars 2.
The vpackers designated generally by A and B have their tubular ortions 3 threaded as at 3a -and screwed into the collars 2,l j-am nuts 4 being provided for purposes Specification of Letters Patent.

OIL- WELL PAKER.
l Patented April 28, 1908.
The upper packer B is of the same construction as the lower packer and comprises a tubular portion 3,'the longitudinally movable sleeve 5 which has a lubricant pocket 50, a` beveled or wedge end 5a and longitudinal grooves 5b for receiving the leaf springs 6 in a manner similar to the packer A. The sleeve portion 3 of the packer B is threaded as at 3b in a manner similar to thelower packers tubular section 3, except that the thread of the upper packer section B is left handed while the lower'thread 3*? of the handed.l l
11 designates the u wardly extending collar which is securely t readed on to the tube ortion 3 of the upper packer B and may be held with set screws 11L if so desired. vThe collar 11 is elongated in shape and is pro` vided with a bayonet slot 11b and a beveled mouth 11c to permit insertion of a pipe 12 having' lugs 12a b means of which pipe the packer is operated?.
In the practical application of my invention, the tubing casing 1lis made of sufficient. length to permit the packers A and B being held oneach side of the water area 13 of the well and preferably the packers A and B are arranged as closely to the water area as possible, thus making it necessary to use a comparativel short section of the tube 1.
In app ying my invention to the well, the tube and packers are lowered into the well as packer A is right shown in Fig. 2 and the tube" or pi e or rod 12 being secured in the sleeve or co lar 11 with its lug 12*i in the bayonet joint 11b.
As soon as the tube and packer has been lowered to a proper position the rod 12 is rotated, thus causing the tube and the tubular section 3 of thepacker to turn and force the sleeves 5 toward their respective packings 8 and thereby expanding the packings 8 until theytightly engage the sides of the well, it
being understood that theleaf springs 6 biting into the well wall or frictionally engaging same, will prevent the sleeves 5 from turning. After the parts have been positioned as shown in Fig. 1 and 3, the operating rod or pipe 12 isfre'moved from the bayonet slot in a manner vwell understood by rei'ernence to the drawings'and Withdrawn from the well.
From the fore oing description, taken in connection with t e accompanying drawings,
. it is thou ht the complete construction, operation an many advanta es of my invention will be readily understoo by those skilled in the art to which it appertains,
Having thus described my invention, what I claimv and desire to secure by Letters Patent, is 1 1.
