ROSS RUE, OF ALLIANCE, OHIO.
SPECIFICATION forming part of Letters Patent N o. 587,274, dated. July 27, 1897. Application filed January 22, 1897. Serial'No. 620,265. (No model.)
To all whom, it' may concern.-
Be it known that. I, Ross RUE, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Ditching-Jacks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon, in which` Figure l is a View showing my device ap shoe B from becoming accidentally displact and lfrom rotation the piercing-points 7c a1 provided, which points become seated'ini the timbers upon which the head B is place against. y
For the purpose of allowing' the jack prope to be set at an angle to the shoe or head l the semicircular recesses J are formed some what larger than the rounded extensions; but said recesses and rounded extensions be ing so formed that the lateral adjustment o the jack proper to the head will be limited plied. Fig. 2 is a side elevation. Fig. 3 is a. The head 7L will properly connect the shoe t( longitudinal section. Fig. 4: is a transverse the screw-threaded shaft C b f means of th sect-ion through line x, Fig. 3. Fig. 5 is a cap f, said cap overlapping the head 71.
transverse section through line g/ y, Fig. 3.
The present invention has relation to ditching-jacks; and it consists in the dierent parts and combination of parts hereinafter described, and particularly pointed out in the claims.
Similar letters of reference indicate corre- For the purpose of connecting' one of the cylinders a to the screw-threaded shaft C, so as to cause said cylinder to rotate with the screwthreaded shaft, the bolt CZ is provided .'which bolt is passed through the head of the screwthreaded shaft and the end of the cylinder a, substantially as. illustrated in Fig. 3. Be-
sponding parts in all the figures of the drawtween the inner ends of the screw-threaded ings. shafts O and C is located the cross-bolt g, to In the accompanying drawings, a a -reprewhich cross-bolt is pivotallyattached the hansent the two outer cylinders, which are located and arranged substantially as shown in the drawings. The inner cylinder b is formed lof a length to correspond substantially with the length of the braces or jack designed to be constructed, except the length is extended at each end bythe addition of the shoes or heads. Within the cylinder h are located the screwthreaded shafts O and O', one of said screwthreaded shafts being provided with a righthand thread and the other with a left-hand thread. The ends of the cylinder b upon their inner faces are provided with screw-threads a', which screw-threads engage the screwthreads formed upon the screw threaded shafts O and C. The screw-threaded shaft O is provided with the flanged head a2, which flanged head is extended and provided with the ball 7i, which ball is provided with the rounded extensions j, which extensionsv are housed'in the semicircular recesses J, said recesses being formed in the cap f, said cap being connected to the shoe or head B by means of the anges f and d, said flanges being securely connected together by means of suitable clamping-bolts.
For the purpose of preventing the head or dle cl2, said handle being for the purpose hereinafter described.
The cross-bolt g is extended through the cylinder b, as illustrated in Fig. 3, and is for the purpose of rotating said cylinder by means of the handle d2 after said handle is turned into the position illustrated in Fig. 2.
For the purpose of strengthening the cylinder b and at the same time stiifening the jack the collar or thimble g is provided and is located upon the outer side of the cylinder h, as illustrated in Figs. 2 and 3. lt will be understood that the cross-bolt g should and does extend through the the purpose of providing a propersurface for the handle d2 to rotate and rest upon and at the same time to provide sufficient bearingsurface for said handle during the time the cylinder b is rotated the flat surface g2 is lformed upon the side of -the collar or thimble g adjacent to the handle d2. It willbe understood that the collar or thimble g may be formed of any desired length, reference loe` in g had to the space between the inner ends of the cylinders a.
The screw-threaded shaft O is provided with the head O2, which head is provided with the collar or thimble g'. For
es c, to which anges are pivotally ated the operating-handles in. The head provided with the ball 7L', Which ball is in place and connected to the shoe B by 1s of the cap g3, said cap and shoe being` ely connected together by the clampingr 1. The heads 7L.' are provided with the ets h2, which sockets are located directly site each other, as illustrated in Fig. 3. n it is desired to prevent the rotation ot shaft C', the setfscrewsgj are seated into ockets h2, thereby holdingboth the shafts d C against rotation, at which time the stlnent of the jack is brought about by us of the handle d2, said handle being ro- :l around the barrel l), carryin g said barvith the handle, at which time the heads 1d B' are forced away from each other at and the same time. rhen it is desired to use the jack with a `le extension, the set-screwsjl are rotated l their'inner ends are removed from the :ets h2, at which time the head or ball 7L' 'ec to turn in its socket', thereby allowing screWthrcaded shat't C' to be rotated inendent of the diiicrent parts of the jack .neans of the handles nl, except the outer rel Ia, located over the screw-threaded tt C 'or the purpose of bringing the handle d2 l position timbers can out of the Way after the jack has been properly adjusted it is preferably turned parallel with the jack, as illustrated in Fig. 3, in which be placed upon the jack without any interference.
Having full y described my invention, what l claim as new, and desire to secure by Letters Patent, isF
l. The combination of the cylinders a, the cylinder I), located parallel within the eylin ders a, the right and left hand screw-threaded shafts C, and G, provided with the balls h and 7L', the shoes B, and B, the thimble 0r collar lf/,located around the cylinder' b, and the cross bolt g, substantially as and for the purpose specified.
2. In a ditching-jack, the combination of the screw-threaded shafts C, and C', cylinders a, securely connected to said shafts, the cyl inder l), and means for holding the screwthreaded shaft C, against rotation, substantially as and for the purpose specilied.
In testimony that l claim the above I have hereunto subscribed my name in the presence of two witnesses.
