4It/iy invention Vrelates to ard'oor.. jack.

An Object ofinyinventio'n is to provide a door jack for the purpose ofrsecuring .a-1do;or.while.it.is beingV planed during the fitting of said door to the door jamb structure.

A further object. oi/myfinve'ntion; ist to provide a door iaclklwhich can be readily folded up to a verycompact form. sogthat it can be transportedV from-.place to Iplace thereby.` eliminating the needfor a long, and cumbersome duorgjack.

A further object' of my invention is to provide adjustable features on the door jack so that it can be accommodated to various door thicknesses.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the door jack,

Figure 2 is a plan view of Figure 1,

Figure 3 is an enlarged sectional view taken along the lines 3 3 of Figure 1,

Figure 4 is an enlarged sectional View taken along the lines 4-4 of Figure 3,

Figure 5 is a detail,

Figure 6 is a plan view of the door jack in its collapsed or portable form, and

Figure 7 is a side elevation of Figure 6.

My invention contemplates the provision of a door jack which can be placed upon the floor and wherein a door can be placed in the jack and planed olf where required so that the door can be properly tted into its surrounding structure or framework, and wherein the jack can be collapsed to a minimum mass for transporting the same.

I have used the character 10 to designate a section of the jack which is made of a flat board, and formed in the member 10 is the groove 11.

Hinged at 12 to the member 11 is a further piece 13 of the same general shape as the member 11 which also has a continuing groove 14 which is of the same configuration as the groove 11 and which groove extends to the end of the board piece 13. The members 10 and 13 include a series of spaced blocks 15 attached therein (also see Figure 3), these blocks being adapted to rest upon the floor surface so that the restricted areas thus provided will allow the jack to be moved along the oor without marring, and will allow readier movability, it being noted that these blocks 15 are so spaced that when the member 13 folds under the member 10, the blocks 15 in the member 13 will be positioned between the corresponding blocks in the member 10 so that the device will fold neatly.

The groove 11 extends to the abutment portion or shoulder 16 (see Figure 4) and hinged at 17 adjacently to the portion 16 is an upwardly extending flat post or abutment unit 18 which extends at a slight angle as rates Patenti@ ice shown in Figure 4, and which'includ'es a vertically positioned 4further groove 19 which is in alignment with the grooves 11 and' 14, the' groove 19 also including a cutaway portion. at 20. which receives' the verticallyy posi-v tioned atstrip' 2'1 to which is attached at 22'to suit'- able washers,V the spaced wing nuts-23 which pass through slots 24', 'which slots 24` areprovided in the member 18,

movement of the strip 21 inwardlyv in.v the direction of4 the. arrow 25 providingv means whereby varying thicknesses of doors 'canbe held within the groove'19."

Hinged; at 26 toone end of the memberA 10 is an angularly extending brace member 27 which `i`s also hinged at 28` to thefrear of the vertically positioned member 18', however, the hinge 26`includes a removable liinge pin 29which is secured to a chain 30 which is attached at' 31 to( the member 10,so that when the hinge pin 29v engag'ing hinge members having a similar removableipiny such as- Jand`b`eing attached to further chains 30` which are attached at 31 to the various pieces as shown clearly in the various gures. Also hinged at 36 to the members 34 are the further braces 37, the hinges 36 also including the hinge pins 29 allowing removal thereof and the same type of chains as described.

The braces 37 are hinged at 38 to the small ears 39 which ears are pivotally secured by means of suitable screws 40 to the brace member 27.

Figures l and 2 show the jack in its normal operating position, and in use one edge of the door, which is indicated by the dotted lines character 41, is placed in the grooves 14, 11 and 19 as clearly shown in Figure l, it being noted that the door will abut against the abutment portion 16, and an upper point on the member 18, due to the slight angularity of the member 18, whereby the door is thus contacted at only two points at the top thereof, which in eifect secures the door and eliminates marring of the door at the upper edge.

It will be Iobvious that an edge of the door can thus be conveniently planed, with the door thus being held rigidly until the surfaces will fit within the frame properly. Either edge of the door can be thus seated in the grooves for the planing operation, the function of the movable strip 21 being already explained hereinabove whereby doors of varying thicknesses can be accommodated.

Since the jack is relatively large in its expanded and operating position, it is important to collapse the same to a minimum size, which I shall now explain. It should rst be observed that the removable pin 29 is used in a variety of locations such as at the hinge 26, at the hinge joints 35, and at the hinge joints 36, Figure 5 clearly showing how these hinge joints are made, one of the parts of the hinge interlocking with the other parts, for instance, as shown in Figure 5, the hinge at 36 including one hinge flap attached to the member 34 and the other to the brace 37, this structure therefore being provided wherever the removable pins 29 are used. In collapsing the arrangement, first, all of the hinge pins 29 are removed from the hinges 26, 36, and 35, and next, the piece 13 is folded at the hinge 12 beneath the piece 10, and then the piece 18 is folded downwardly against the piece 10, and next, the braces 37 are pivoted inwardly on the pivoting points 40 where they will lie directly against each other, and next, the outspread legs 34 are folded inwardly against the side of the entire arrangement, and then any type of straps 42 are strapped about the arrangement as clearly shown in Figures 6 and 'I invention with various other advantages being readily apparent.

Some changes may be made in the construction and arangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modied forms of structure or use o'f mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

A door jack comprising a horizontally positioned base member having a longitudinal groove therein for receiving a side edge of a door, a substantially vertically positioned member attached to said base member and having a further groove therein substantially in alignment with said groove, said substantially vertically positioned member being slightly pitched from the vertical, and further including a laterally movable strip for accommodating varied door thicknesses, said horizontally positioned member including a pair of mutually pivoted sections whereby said sections can be folded together, said sections includzontally positioned member including laterally positioned legs hinged thereto, said laterally positioned legs including further hinge portions including further hinge pins whereby removal of said further hinge pins will allow folding of said legs inwardly, further normally angularly positioned braces pivoted to said brace, and removably hinged to said laterally positioned legs and including still further hinge pins at the hinging points thereof, said further normally angularly positioned braces being pivotally secured toward the upper end of said brace whereby said angularly positioned braces can be folded inwardly after removal of said still further hinge pins.
