Abstract
Abstract An apparatus for use in marking doors for cutting is provided, usually used for shortening previously hung doors to swing freely over newly applied carpeting and the like. The door is removed, and an upright is suspended from the fixed hinge portions on the door frame, and adjusted until a horizontal template at the bottom of the standard swings freely over the carpeting. The standard is placed on the door and the door marked along the template to indicate where the door is to be cut.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
An apparatus used for laying out the lower edge of hinged doors including cooperable hinge portions on the door and on the door frame, the apparatus including: a standard, a template arm mounted at the lower end of said standard, said template defining a reference line in generally right angular relation to the axis of said standard, a pair of brackets adjustable longitudinally along said standard having longitudinally aligned bearing means, each including an opening supported thereby, said bearing means supporting said standard upon said hinge portions secured to said door frame by means of hinge pin members respectively extending through each of said hinge portions and the opening in the associated bearing means, said apparatus further including means for supporting and constraining said template arm for pivotal movement about an axis co-directional with the axis of said standard.
Claim 2
Independent Claim
139 words
An apparatus used for laying out the lower edge of hinged doors including cooperable hinge portions on the door and on the door frame, the apparatus including: a standard, a template arm mounted at the lower end of said standard, said template defining a reference line in generally right angular relation to the axis of said standard, a pair of brackets adjustable longitudinally along said standard having longitudinally aligned bearing means, each including an opening supported thereby, said bearing means supporting said standard upon said hinge portions secured to said door frame by means of hinge pin members respectively extending through each of said hinge portions and the opening in the associated bearing means, said apparatus further including means for supporting and constraining said template arm for pivotal movement about an axis co-directional with the axis of said standard.
Claim 3
Dependent Claim
21 words
The structure of claim 1 and including means for securing one of said adjustable brackets in fixed relation to said standard.
Claim 4
Dependent Claim
19 words
The structure of claim 2 and in which the said one bracket is the upper bracket on said standard.
Claim 5
Dependent Claim
18 words
The structure of claim 3 and in which the lower said bracket is freely slidable along said standard.
Claim 6
Dependent Claim
41 words
The structure of claim 1 wherein said means supporting and constraining said template arm are included in said bearing means and comprise means supporting and constraining said bearing means for pivotal movement about the axis formed by said hinge pin members.
Claim 7
Dependent Claim
22 words
The structure of claim 1 and in which said hinge pins include stepped longitudinal portions of varying diameters to accommodate different hinges.
Claim 8
Dependent Claim
25 words
The structure of claim 1 and including a template arm extension adjustably supported by said template arm for extending the length of said reference line.
Claim 9
Dependent Claim
44 words
The structure of claim 1 wherein said standard includes a vertically extendable upper portion for engagement with the top of said door frame, said upper portion having a projecting member at the upper end thereof for engaging the top portion of the cooperable door.
Claim 10
Independent Claim
184 words
The method of laying out a door hingedly connected to a door frame by vertically spaced hinges for cutting off a portion of said door in order to provide swinging clearance between the door and a carpet or the like, through the use of a standard supporting vertically adjustable brackets, and a template arm extending in substantially parallel relation to the lower end of said door frame, said brackets and standards supporting said arm for a swinging movement with respect to said spaced hinges, the method consisting of: removing the hinge pins from said hinges and removing the door from the door frame, attaching the standard to hinge portions on the door frame for swinging movement similar to that of the door, adjusting the hEight of the template arm relative to the brackets so that the template arm will swing freely, removing the standard from the hinge portions on the frame and placing the standard and template on the door with the brackets lined up with the hinge portions of the door, and marking the door along the lower edge of the template arm.
