UNITED STATES g 1,575,254 PATENT OFFICE.
ERNEST S. CORY, OF BIRMINGHAM, ALABAMA.
TOOL.
Application ined May 2,
Z 1o all whom t may concern:
Be it known that LERNEsT S. Conr, a citizen of the United States, and resident of Birmingham, in the countyV of Jefferson and State of Alabama, have invented certain new and useful Improvements in Tools, of which the following is a specification.
My present invention relates to a device for laying olf window jambs 'of .either the plain or plowed type.
The principal object of the invention is to facilitate the laying olf of the beveled bottom end of a window jamb which adjoins the sub-sill, and at the same time to provide means which will quickly indicate thepoints on the jamb adjacent the header for t 1e bit holes which are afterward chiseled out to receive a single or pair of pulleys, as the case may be.
Another' important object of the inven-4 tion is the provision of a single device which will, in a few operations, do the work of several tools now found necessary, and in an efficient manner.
Further 4objects and advantages will appear asthe description proceeds.
In order to accomplish the above end I have designed a device, and my invention includes a tool similar to a carpenters square, except that the base ofthe L instead of having a single straight edge, has two edges in angular relation to each other equal to the angle which the uppei` surface of a sub-sill makes with the window jamb. The main branch of the L is provided with projecting points which are secured therein and project from the bottom of the tool so that when a blow is struck above the points, these points will be driven intov the wood of the jamb and indicate therein the positions in which holes are to be bored by the ordinary bit, later to be chiseled out to receive the single or a pair of pulleys, commonly used. I contemplate making these projecting points removable and providing several series of holes in the tool so that the points may be removed from one hole to another in order to adapt the tool to various sized pulleys. Overlying all of the points I provide a leather, fabric or other protecting element which is secured to the tool so that the carpenter or mechanic using the tool may use his hammer or mallet and strike the leather or fabric, which will reduce objectionable sound to a minimum. In the use of the tool for plowed jambs in which there is a longitails of construction, arrangement, and com-v bination of parts hereinafter shown and described.
I have illustrated in the accompanying drawings the most satisfactory form of which I am now aware, although obviously I do not wish to be limited to the form shown.
In this drawing Figure l is a plan View of one form of my invention.
Fig. 4: is a plan view showing the device as .used on the work.
Fig. 5 is a plan view showing the device as used in a plowed j amb.
Fig. 6 is a fragmentary 'plan view of a jamb showing the punch marks.
Referring now to the embodiment illustrated I have shown a. square or tool consisting of the leg l and the leg 2.` This tool may be made of any desired material such as njjolod or metal, although metal is prefera e.
The inner edges of the legs 1 and 2 are straight and at right angles to each other and I propose to indicate on each edge beginning from the point of intersection of these edges, inches and fractions thereof. The outer edges of the leg 2 is arranged at an angle as indicated at 3 and 4t, the angle of these edges being determined by the ordinary degree of angularity occurring between the upper surface of a subsill and the lower adjacent portion of a window jamb. The leg 1 of the tool is provided with screw thread-ed apertures 5 adapted to receive projecting points 6 screwed therein so that the tops of the| points 6 are flush with the main surface of the leg l. A plurality of these screw threaded apertures 5 are provided for a purpose which will be more fully described hereinafter.
Cil
ally oi a constant width, it is contemplated. that a tool will be used so tha the adjacent longitudinal edges; of two jambe will pass throughk the point ot intersection of2 the edges 3 and i o't' the leg` Q. In such position, by drawing a pencil line along the edges 4L and 8, it will be apparent that two jambe may be marked at once making a proper angle to adapt it to engage the sub-sill of a window.
Having thus marked the angular end andk measured olif the properlength of: the
jamb, the juncture of the outer edges` oi'v the legs is then placed at a corner oi the opposite squared end of the-jamb-so that the projecting points G occupy the-position lat- IVheni the.
er to be taken by the pulleys. tool; has .been placedin suehzpositioma `blow ot a hammer or mallet upon the strike pad 7 will drive thel projecting points into, the wood and thus indicate to the mechanicV where the holes are to bev-drilled bythe bit, instead of having to make several; measurements with a rule to determine this position.
Obviously the projecting| points 6 may be placed in any ofy the screw, threaded apertures 5 to correspond with, the.: various widths or lengths of pulleys used, andf'or this reason I provide a number of' aperturesl 5,
with which the projecting terchangeable.
Some Window j ambs are known as plowed jambs, lthat is, they havea Longitudinal groove therein usually of 1/1'2 inch;` or there-v abouts into which is ordinarily inserted the points 6. are inparting stop which separates the two. window sash. In adapting the tool to the marking oli' or laying out of such jambs, I provide on the under side of the leg l alignment stops 9 secured to the leg l as by` screws 10. These are preferably of metal and are so located with reference to the projecting points 6 that when the tool is placed on a plowed jamb the stops 9 in entering the groove on a. plowed janib, will accurately center the points (l. This saves the trouble oit aligning the etr-aight edge of the leg, l with the straight edge oi the jamb.
An aperture ll is provided in the lower part of. the legv l so that the tool may be hung` up it. desired.
@bviously the strike pad may be perforated to allow the projecting points to be removed therefrom and placed in other screw threaded apertures without removing the. strike padi itself;
Having thus described my invention, what I; claim is:- l. A tool comprising; a main legand a supplemental leg., the inner straight. edge on one leg; joinllggalll inner straight edge on the other at right angles, points secured to y oney legjandl proj eetina;r from the surface thereofyanch a strike padsecuredto one o'l" gauge secured t0 the main legy comprisingpoints` projecting; from the under sur-face tliereof ar strike pad secured to. the opposite side of themain leg and overlying the heads of the projecting points, and" alignmentstops secured to the under surface of the.V main le0.
In` testimony whereof', Iv affix my signature.
