This invention relates generally to hand tools and more particularly to a carpenters tool of the general character of a vise for holding doors, window sashes and the like, while the same are being worked upon by a craftsman.
The device has been developed primarily to hold doors or the like in a vertical position so that operations may be performed, as for example on the style of the door, in sawing, planing or the like, or in the installation of locks,-and it will be noted that the door can be supported against swinging or sagging while operations are being performed on the door or the hinges thereof while the door is still at least partially supported by the hinges, similar operations being envisaged with regard to window sashes and like structures.
Another object of this invention is to provide these tools with not only a screw jack whereby the work may be clamped in the tool, but also a lever jack for raising and lowering at least a portion of the tool, with the work clamp therein.
Yet another object of this invention is to provide such a tool with a lever jack, the lever or handle of which is of a considerable length and adapted to function as the spacer or abutment member which can be made to engage a wall or other fixed vertical structure, so that the tool and the work clamp therein may be more rigidly supported, thus facilitating an operation such as sanding, planing or the like.
Yet another object of this invention is to provide the tool with a jack lever, as mentioned above, and to provide the jack lever with a heel portion extending beyond the pivot point of the lever and carrying an anti-friction element which can be made to engage the floor when the lever is raised, thus not only raising the tool but also providing for easy rolling of a heavy door along the floor.
A last object of the invention specifically is to provide a device of the character mentioned above which is relatively inexpensive and practical to manufacture, which is safe, simple and expeditious in use, and which will give generally efiicient and durable service.
With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claims, and illus trated in the accompanying drawings which form a material part of the specification, and in which:
Figure 1 is a fragmentary view of a door with 2 Claims. (Cl. 144-296) this invention operatively secured thereon, the
lever jack being in a position to raise the tool and,
the work clamped therein a short distance above the floor;
Figure 2 is a somewhat similar figure, also in perspective, showing the jack lever in lowered position and in engagement at its outer end with a vertical wall structure, as when the jack lever is used to stabilize the tool so that the work clamp therein is more firmly held during an operation such as planing or sanding the style of the door;
Figure 3 is a fragmentary top plan view of the invention, the figure also including a fragmentary portion of a door; I
Figure 4 is a fragmentary vertical sectional view, taken on the section line 4-4 in Figure 3; and,
Figure 5 is a vertical sectional view taken substantially on the line 55 in Figure 4.
Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views of the drawings.
Referring now to the drawings in detail, this tool includes a base comprised of angle plates ID and I2 having vertical flanges I4 and I6 spaced apart and arranged in opposing relation as clearly indicated in Figure 3. A pair of blocks I8 and 20 are rigidly secured in upstanding position and.
spaced apart, upon the upper faces of the angle plates I0 and I2. These blocks may be integral with the angle plates, if desired. A lower cross brace 22 and an upper cross brace 24 are welded or otherwise suitably secured to co-planar faces of the blocks l8 and 2|], and the lower brace 22 is also rigidly secured to the ends of the upright flanges l4 and L6, whereby a work receiving space is provided in the tool and is defined in part by the opposing flat faces of the blocks l8 and 20 and the cross braces 22 and 24.
A resilient pad 26 is rigidly mounted by any suitable means on the flat face of the block 20 adjacent to the block 18, and this pad 216 has a work engaging flat face. An enlargement 28 is formed in the upper portion of the block l8 and a threaded shank 30 of a screw jack comprised of this threaded shank, a manual control knob 32 and a work engaging head 34, is operatively mounted on the enlargement 28, the threaded shank 3|] being threaded transversely through the enlargement 28, with the head 34 registering with the upper portion of the pad 26.
The angle plates l0 and I2 have feet 36 on the portion thereof adjacent to the blocks [8 and 20.
A lever jack assembly provides adjustable support the lever iadepressed, as illustrated in Figure 2,,
this foot 42.,enga'ges'the. floor and,.'along with the,
feet 36, supports the tool and any work clamped therein. The lever has a bifurcated heel por: tion 44 with a floor contacting roller 46 rotatably mounted between the furcations, this rollenbeingzi preferably rubber tired, as indicated as-at*48 and the distance between the. pivot bolt-.40 and...
the edge of the roller remote-therefrom is great:- er than the distance from the pivot bolt 40 to the under face of the foot 42, so that when the lever 38 is moved into the position indicated in Figure l at least one side of the tooliisraised.
Ordinarily the whole tool and work clamped thereinisalsp raisedwhen the lever is movedfrom themsition indicated in Figure 2 to the. position indicatedinFigure-l.
The work used with this invention is illustrated by the. door 50 and. a .wall 52. is indicated inFigure.2,,.. and the operation of. this invention. will her-readily understood from a consideration. of theioregoing. description of. the. mechanical details thereof, when takenin. connection with the above recited objects and thedrawings. In' recapitulation, itwill be, noted that the work 50' is clamped betweenthe pad 26 and the. screw jack head 34; Whenfurther, support is1requir.ed,i'as in planing the style of a door. 59,. the lever 38 maybe. made to. abut the. wall 52.. Ordinarily theworkman doesnot need to. straddle the door in planing the same or in installing a lock inthe door.. When it is desiredtoraise the work slightly, the lever 3.8 is raised. asindicat/ed in Figure 1. Otherwise the foot 42' coacts with the feet 36 to support. the tool...
Having described the invention, what is claimed as new is:
1. A carpenters tool comprising a base, upstanding blocks rigidly secured on said base in horizontally spaced relation, a screw jack operatively mounted in one of said blocks and having a work engaging head on the side of said one block adjacent the other block, a pad on said other .block and.v having a work engaging face opposite said head, and a jack mounted ,on said base for elevating the tool comprising a lever pivoted on said base and having a heel projecting beyond'the pivot of the lever, and an anti-friction-'element on said heel engaging the surface whereon the tool is supported when the lever is raised; said lever. having a foot on one side thereof.,adi.aeent-the pivot of the lever and engaging the floor when-.thelever is lowered.
2. A. carpenters tool comprising a base, upstanding blocks secured on said base in horizontallyspaced relation, means for clamping a work piece between said blocks, and a jack mounted on .said base. forelevating, the tool comprising a lever. pivotedon said base and having a wheel projecting beyond. the pivot of the lever, and an anti-friction; element on said heel engaging the surface wherein the tool is supported when the-lever :is.raised-,-. said lever having a foot on oneusideithereofi adjacentthepivot of the lever andengaging the floor when the lever is lowered.
