The present invention relates to a prototype for gaging the contour of an opening for use as a guide in cutting a closure therefor.

One object of the present invention is to provide, in a device of the character described, improved means which permit the adjusting of the pattern device or prototype to the size of an opening to be closed and subsequently cutting the closure to fit said opening from the form thus provided.

Another object of the present invention is to provide a device of the above stated character equipped with cutting means which will provide the desired bevel on the door or other object being cut for an opening.

Another object of the present invention is to provide a device which can be more quickly and accurately adjusted for measuring and subsequently cutting a door or other object so that it may be more quickly and accurately fitted to, and hung within a frame or opening.

Still another object of the present invention is to provide a device of the character described affording means whereby the door or other object may be fitted, cut and hung with exacting accuracy within its opening with a considerable saving of time and by a single workman without the aid of an assistant.

Yet another object of the present invention is to provide a device of the character described which can be so adjusted as to provide the necessary clearance for the door or other object which is to be fitted and hung.

Still another object of the present invention is to provide a device of the character described which is more efiicient in operation and yet simple in construction and economical to manufacture.

With the above and other objects in view as will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, as hereinafter more specifically set forth, claimed and shown in the accompanying drawings which form a part of this application for Letters Patent.

In the accompanying drawings are illustrated preferred and practical embodiments of. the invention, it being understood, however, that the drawings are merely illustrative and that the inventive concept is susceptible of other embodiments and utilizations, and that the illustrated embodiments likewise are susceptible of a wide range of variation and modification without departing from the spirit of the invention or the scope of the appended claims.

Referring now in detail to the drawings and first adverting to Figs. 1 to 5 inclusive, the reference numeral I has been used to generally designate the frame of this new and improved measuring or fitting device embodying the present invention. This invention has been described in conjunction with the fitting, measuring, cutting and hanging of doors in door frames or lambs, and it is to be understood that this has been done in order to facilitate the description of the present invention, and has been done by way of illustration and not by way of limitation. The measuring or fitting device of the present invention may be made from any desired material, such as, for example, wood, metal, plastic, hard rubber or any other suitable material and it may be made so that it may be adjusted to any desired shape or size so as to be fitted within a variety of different sized openings. This measuring or fitting device has at each side an outwardly and inwardly adjustable side bar structure comprising an inner bar 5 and an outer bar ii; and a vertically adjustable top rail structure 9, suitably secured to the frame I as shown most clearly in Figs. 1 and 2. It will be readily seen and understood from this arrangement that the movable side and top structure may be changed into a variety of sizes and shapes so as to fit a multiplicity and variety of openings varying in contour.

In order to take care of various irregularities of contour in the borders of the openings to be gaged, the adjustable side bars 5 and zfi at each side of the device are spaced apart from each other by the spacing means 8, as clearly shown in Fig. 1. The bar members and 6 may be connected together by suitable threaded means I6 passing through and secured to a nut I as is shown most clearly in Fig. 5. This arrangement permits the outside bar 6 to be moved the necessary distance away from the inside bar 5 by flexing it so as to fit any irregularities in the door frame H, or to fit an opening bordered by warped timbers. The inside bar members 5 are adjustably connected to the frame member 1 by any suitable means, such as, for example, the threaded rod members 4 which may pass into correspondingly threaded tube members 3, the said threaded tube members 3 being suitably secured to a post 2 and the sides of the frame I by any suitable securing means, as is shown most clearly in Figs. 1 and 3. This arrangement provides for lateral movement of the bars 5 and 6 toward or away from the frame I as may be necessary in order to fit the opening in which the door is to be hung. The three posts 2 carried by the midwidth portion of the frame are all directed lengthwise of said frame, and therefore, do not project objectionably from its face. Each screwthreaded rod 4 has one of its end portions passing loosely through a smooth bore for it in a said post, while the opposite outer end portion of the bar is no'n-turnably secured to the adjacent rail 5 and spacer 8. As already alluded to, each of said rods 4 is in a screwthreaded relation to an aforesaid sleeve 3 which surrounds it, the outer end of said sleeve loosely abutting a side of the adjacent post; ie'nce the workman, by rotating said sleeves can adjust said rods as desired and thereby adjust bodily the pair of bars 5 and ii, at the sides of the frame. In Fig. 2 the ends of pairs of bolts appear in the rail 5. In the assembled structure, at each side of the frame each said pair of bolts extends into the underlying spacer 8, thus securing said spacers to said bars.

The top member or rail 9 is fitted over a carrymg member if}, as is shown most clearly in Figs. 1 and 4. The member it which carries the top rail 9 is m'ovably secured to the frame I by any suitable means, such as, for example, the threaded rod II which passes through a correspondingly threaded nut I2, down through the frame I where it terminates in a second threaded nut I5. If desired, a suitable spring member I3 placed between the frame projection I and the washer M on the nut I5, may provide suitable loading to maintain the top rail 9 in the correct measuring position, as is shown most clearly in Figs. 1 and 4. The provision of a pair of these adjustments, one on each end of the carrying member I 0, affords means for adjusting to any opening, even if the opening is irregular or slanting. The provision of a removable top rail 9 carried by the carrying member ID provides means for easily and quickly changing the size or shape of the top rail 9, as desired, in order that a wide variety of shapes and sizes of openings may be measured.

The operation of the new and improved measuring or fitting device of the present invention is quite simple. The frame member I is first placed in the opening to be measured or fitted, between the door framing members IT as is shown most clearly in Fig. 1. The side bars 5 and t are then moved outwardly by means of the screw adjusting means 2, 3 and 4 until the outer bar 6 touches the sides I! of the opening to be measured or fitted. Considerable crookedness or warping in the timbers I! may then be gaged by means of the adjusting means I and I6 located between the side bars 5 and 6, so that an absolutely accurate fit may be obtained. This gaging operation is effected by turning the nut I, together with the reversely screwthreaded end portions of the rod It so that the latter will bow the resilient bar 5 to conform to the warped surface it engages or conforms to. By the aforesaid adjusting means both a simple and compound outward bowing of the side portions of the prototype can be effected. The top rail 9 is then moved upwardly to fit against the top of the opening in the frame H, by means of the adjusting means II, I2, I3, I4 and I5, as already described. Any irregularities, warping or crookedness in the top timber I? of the door framing may be adjusted for by means of the adjusting means II, I2, I3, I4 and I5 so that an absolutely accurate fit may be obtained. When the proper adjustments have been made the frame I and its accompanying parts may be removed from the opening and an absolutely accurate pattern for the door which is to be hung is thus obtained.

Figs. 6, 7 and 8 show the cutting means designed to be used in conjunction with the measuring or fitting means previously described. The cutting means has been generally designated by the reference numeral 23 and comprises essentially a driving means or motor I9 adjustably secured to a motor mount member 29, the motor mount member 28 being carried by a suitable flat plate member 2| to which the said motor mount member 20 is either suitably secured, or is made an integral part thereof, as desired. A suitable rotary cutter 23, is secured to the lower end of the downwardly extending shaft 22 of the motor I9 by any suitable means, such as, for example, the lock nut 24. If desired, a suitable guard means 25 may be secured to the bottom of the plate member 2| by the screw bolts I8, around the cutter 23, so as to protect the user from being accidentally out while using the invention. A suitable adjustable guide member 26 is carried on the bottom of the plate member 2! to provide means for regulating the depth of out. The motor I9 may be pivotally secured to the motor mount 26 by any suitable means, such as, for example, the bracket member 29 which may be securely affixed to the motor I9 by means of the bolts 28, as is shown most clearly in Fig. 6. The lower end of the bracket 29 may be pivotally secured to the motor mount 2!! by any suitable means, such as, for example, the pivot pin 21. Adjusting means, such as the adjustable screw bolt 3!) at the top of the bracket member 29 provides for producing a bevel cut on the mate rial by moving the motor shaft 22 away from th vertical, thus aiding in producing a bevel cut on the door which is to be hung, so that it may accurately fit the door opening.

The operation of the cutting device with the fitting or measuring device is relatively simple. After the door opening has been accurately gaged by the fitting or measuring device as previously described, the fitting or measuring device is placed over the door which is to be hung. The cutting tool is then brought up to the work and placed 'over the fitting or measuring device as is shown most clearly in Fig. 6. The cutting guide member 26 is then adjusted for the proper depth of cut, and, if necessary, the motor 19 is tilted the proper amount by means of the adjustment screw 30, so as to provide-a beveled cut, and the guide member 26 is then moved along the edges of the fitting or measuring device and the door is then cut to the proper size after which it is ready to be hung and a perfect fit of the door or other object in the opening is thus obtained.

It will be observed that a rotary cutter is used in trimming the door, said cutter rotating about an axis which extends transversely of the plane in which the prototype lies, said cutter being adjustable to vary the inclination of its axis of rotation. Also from Figs. 6 and 8 it will be seen that the plate 2%, which mediately carries the motor and cutter, is sufficiently long readily to be moved across the gaps at the corners of the prototype. Also owing to all the fasteners, bolts and operable parts of the prototype being located between the planes defined by the smooth outer side faces of the prototype, no obstacle is encountered by said plate when it is used in the manner already described; and the rotating cutter causes no objectionable vibration.

It is to be understood that the forms of the invention herein shown and described are to be taken as preferred and practical embodiments of the same, and that various changes may be made in the shape, size and arrangement of parts without departing from the spirit of my invention or the scope of the appended claims.
