flanges I! when the parts are in collapsed position as seen in Fig. 4 of the drawing.

The lower ends of the plates I6, Ilia of the standard are joined at one side by a rivet or coupling pin which prevents a spreading of said plates, and at the same time permits the swinging movement of the lever into the space 36 between adjacent faces of the plates when in the collapsed position shown in Fig. 4.

In the use of the tool, it will be understood that the part 28 of the lever may be raised and lowered in the post or standard ID to dispose the pivot pin 26 in either one of the offsets 23, 24 and 2 5, the same being shown in the offset 25 in the construction shown in Fig. 1. the head 36 is placed beneath thehand grip- I3 of the sash l2 and downward pressure is applied on the part 3| of the lever which will operate to disengage a binding or sticking sash l2. In this connection, it will also be understood that the pin 26 may be disposed in either one of the apertures 2'! to increase or decrease the length of the protruding end of the lever part28 with respect to the standard, or as seen in Fig. 6 of the drawing, a lever part 28a similar to the part 28 may have in its lower edge a series of recesses 31 to engage the pin 26' to provide this adjustment without removing the pin 26 from the standard or body l6.

It will be understood that while I have illustrated the device as used for the purpose of. raising or freeing window sashes, the same may be .used for any other purpose as a jack or lifting tool, and while I have shown certain details of construction for carrying my invention into eifect,

and modifications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificingits advantages.

Having fully described my invention," what I to secure by Letters 1. A device of the class described comprising a standard consisting of parallel plates spaced apart ,to form an elongated recess therebetween, a rela -tively long lever disposed in the recess of said standard, means for pivotally supporting one end portion of the lever to said standard to dispose one short end of the lever outwardly of the standard, said short endhaving a transversely offset member, and said lever including relatively movable parts adapted to be collapsed to dispose the same in substantially parallel relation with each other and to the longitudinal plane of the standard, and one part-of. said lever disposed within the recess of the standard when in collapsed position.

cluding pivotally coupled parts adapted to be folded into parallel relation with respect to each other, one part being disposed within'the post and the other part being oifset to clear the post to dispose said parts of. the leversubstantially,

not in use.

3. A device of .the class described comprising a stock or body, a relatively long lever, means for pivotally supporting the lever in connection with said body, said body comprising parallel sheet When so positioned,

7. In a lift device of the class described, a standard fashioned from a single strip of metal, each ,end portion of the strip being of similar construction and comprising an elongated plate having side flanges and an elongated aperture havinga plurality of oifset sockets, the strip being folded centrally to dispose said plates in parallel and spaced relation with respect to each other, means at one lower corner portion of said plates for coupling and spacing the same in forming said standard with the aperture and off- ,set sockets of said plates disposed in common transverse alinement, and the central portion of "the strip being cut out where folded to form at the upper end of the standard a large opening extending through the top and one side of the standard. parallel to the longitudinal plane of the post when I '8. In a "lift device of the class described, a standard fashioned from a single strip of metal,

ing folded centrally to dispose said plates in parallel and spaced relation with respect to'each other, means at one lower comer portion of said plates for coupling and spacing the same in 'forming said standard with the aperture and oilset sockets of said plates disposed in common transverse alinement, the central portion of the strip being cut out where folded to form at the upper end of the standard a large opening extending through the top and one side of the standard, and an elongated sheet metal lever having a pivot pin adapted to be arranged in the apertures and offset sockets of said plates in adjusting the lever vertically in said standard, and the free end of the lever including a cylindrical head 011'- set laterally with respect to said lever.

9. In a lift device of the class described, a standard fashioned from a single strip of metal, each end portion of the strip being of similar construction and comprising an elongated plate having side flanges and an elongated aperture having a plurality of offset sockets, the strip being folded centrally to dispose said plates in parallel and spaced relation with respect to each other, means at one lower corner portion of said plates for coupling and spacing the same in forming said standard with the aperture and offset sockets of said plates disposed in common transverse alinement, the central portion of the strip being cut out where folded to form at the upper end of the standard a large opening extending through the top and one side of the standard, an elongated sheet metal lever having a pivot pin adapted to be arranged in the aperture and offset sockets of said plates in adjusting the lever vertically in said standard, the free end of the lever including a cylindrical head offset laterally with respect to said lever, and said lever including a handle portion offset with respect to the lever proper and pivoted thereto to dispose the handle portion in common transverse alinement with the lever and both parts of the lever in parallel relation to the standard when the parts are 20
