PIPE-FORCING JACK.
To all whom it may concern:
V'Be it known that I. JOHN E. HiLuEas,
citizen of the United States of America, re-
siding at Middleton, in the county of Dane and State of "isconsim have invented certain new and useful Improvements in Pipe Forcing Jacks, of which the following is a specification.
This invention relates to pipe jacks and especially to a device of this character that may be used in driving` or forcing pipes or other like objects. I
The object of this invention is'to consti-'uct a simple, cheap and durable device of this character that will he easy to manip ulatc and one that will have a powerful maximum leverage.
`With these and other objects in view the Y invention consists in the novel details of construction and combination p more fully hereinafter described and particularly pointed out in the claim.
Referring to the drawings forming a part Vof this specification in which like fi ures designate like parts in all the several views: Figure 1 is a side elevational view of my improved pipe jack; Fig. 2 is an end view, as shown looking from the right. of Fig. l: Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 4. Fig. 4 is a horizontal sectional view of my device. Fig. 5 is a cross sectional view taken on the line 5-5 of Fig. 4. Fig. 6 is a detail perspective view of the dog holder and Fig. 7 is a detail perspective view of one of the dogs.
My invention com rises the frame 1 having the base 2 and si es 3 which are adapted to support on theirupper forward ends the shaft 4 which shaft is held in said sides by the cotter pins 4. These sides are also reinforced as indicated at 5 and are provided on their inner sides with the longitudinal grooves 6, in which is ada ted to travel the dog holding frame 7. l\ ounted on the shaft 4 within theframe is the lever socket 8 having the sleeve 9 which is provided with the downward projecting lu s 10. 1l indicates a handle removab y mounted within said socket 8, which is adapted through the connecting links 12 to operate the dog holding frame. These links Specication of Letters Patent.
Application nled Aprl 20. 1911.

are pivotally connected, at one end. as iudicated at 13, to the lugs 10 and at their other ends they are pivotally connected by'` the studs 14 to the dog holding frame T. This dog holding frame is preferably rectangular in shape and is provided with the hollow portion 15, a central openingr 1G for the passage. of a pipe, and lugs 1T on the sides thereof, which are adapted to travel within the longitudinal grocves (l. livotally mounted, as shown at 1S. within the hollow portion l5, and diametricallv opposite each other are two dogs 1l) which are lnovided en their faces with thc teeth 120.' 'l`he faces of these dogs are in alincmcnt with t-he pipe-v and force the lever forward until the end ot the stroke has been reached: the lever is then returned and duringr this return movement the jaws release their hold on the pipe and are returned. This operation will he repeated at each stroke and it will be seen that', on account of the lever heingpivotally supported at right angles to the dog: holding frame a powerful leverage can be ohtained.
B v slidahlyr mounting thc dog holding frame within the stationary` frame. hy rcinforcing both frames thereof and b v the construction and arrangement of parts. very heav` pipes and the like can be easily and conveniently driven or forced any desired amount.
The device is adapted to bc used on pipes of various sizes, from a pipe to a pipe of H".
W'hat I claim as new and desire to protect by United States Letters Patent is:
A pipe jack comprising a stationary frame having reinforced sides provided with grooves: a rectangular dog holding frame. having a central opening and inovable in said grooves; a pair of oppositely disposed dogs vmounted in sad movable Tn testimony whereof I afflx my signature Y frame und m almement mth said opening; 1n presence 0f two wltnesses.
f n lever fulcrumed 0n sald statlonary frame; f
' Y Vlugs mounted on said lever; and links piv JOHN E" HUGLRS' v 5 otally mounted within said movable 'frame Titnessesz and connected to said lugs; substantialy W. VVIERSTORFF,
