GAGE FOR MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 360,213, dated March 29, 1887.

Application filed May 13, 1886. Serial No. 202,117. (Motleh) To all whom it may concern.-

Be it known that I, WILLIAM T. FARRELL, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Gage for Use in OI'klHg Moldings, of which the following is a full, clear, and exact description.

The object of this invention is to promote accuracy in obtaining lines, angles, &c., in working stone and t0 economize time and labor in such work.

The invention consists in the means substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my improved instrument, part of the scriber being broken away to show the serrated or file-like inner surfaces of its sides. Fig. 2 is a section on the line a :17, Fig. 1, the scriber having been removed. Fig. 3 is an edge view showing the blade inserted in the head of the bevel, the said head being in section. Fig. 4 is a plan view of the circular base of a columnwith my improved instrument thereon in position for use. Fig. 5 is a section of part of such base on the line 313 in Fig. 4, and showing the instrument in side elevation and in dotted lines the profile of the molding to be worked. Fig. 6 is a face view of a block of stone on which a molding is to be worked longitudinally,showing the instrument as applied to obtain the necessary lines. Fig. 7 is a side view of a molded cornice, taken in the direction of the arrow in Fig. 8, and showing the instrument as applied to obtain the miter-line for returning the molding. Fig. Sis an end view of the same, illustrating also the application of the plumbpoint to ascertain if a member of the molding is level in the direction transverse to its length.

The bevel-stock A is provided with alongitudinal slot, a, at right angles to the main slot, formed by the two sides of the stock, and on one of its side faces with a graduated sliding plate, B, and apointer, b. The stem or shank b, on which the pointer I) is mounted, extends through the said sliding plate and stock, and is provided on its opposite threaded end with a nut, O, for binding the disk 13 011 the bevel at any desired point along the same. Intermediately of the nut G and graduated plate B,

between the two sides of the bevel, the stem 1) is provided with a catch or projection, c, for engaging the slotted end of the graduated blade D when the latter is inserted in the open side edge of the bevel-stock,the catch entering the slot of the blade. iVhen the blade D is swung either to the right or left, it will turn the pointer, and the angle formed by the blade D and the side edge of the bevel will correspond to the angle indicated by the pointer, as will be readily understood.

The scriber E is slotted longitudinally, as shown clearly in Fig. 7, so that it may ride on the blade D and bind thereon at any point. The inner faces of the sides of the scriber that is, the parts of the scriber forming the walls of the longitudinal slot therein-are serrated or file-like, as shown at a, Fig. 1, to enable the operator, with but a slight pressure of the fingers, to bind the said scriber on the blade D when desired. The scriber is also, by preference, provided with a swivelsoeket, F, for the pencil G.

To obtain the lines of a longitudinal molding after the profile of the molding has been indicated on the end of the stone with the aid of the mold or pattern in the usual manner, the bevel A, carrying the blade D and scriber E, is placed on the top bed of the stone, as in Fig. 6, and the point of the pencil placed on the point at the end of the stone from which the line is to start, and the instrument is then moved or slid alongthe stone, the bevel being held down on the top bed, and the scriber will trace the line as it moves along. The pencil is then shifted to where the next line is to be traced, and so on as before. \Vith the inner surfaces of the sides of the scriber serrated, as before mentioned, a slight pressure of the fing)ers will sui'iice to firmly bind it on the blade while the line is being drawn, and by reason of the swivel-socket F the pencil will accommodate itself to the slight irregularities of the stone.

To obtain the lines for working a molding on a circular base, the bevel is placed on the top bed of the stone, the same as in the instance above mentioned, and the pencil placed on the stone at a distance from the top corresponding to the distance therefrom of the member to be worked, and the instrument is swung around on the top bed till the line is completed around the stone. The pencil is then moved down to where the next line is to be traced and the operation just described repeated. The advantages of the instrument in obtaining these lines will be readily apparent to practical stonecutters.

In a recess in the end or head of the bevel is fitted the two-part revolving socket H for the blade D, the parts h h of the said socket being made gradually wider toward the bottom, and at the extreme bottom edge are each formed with an outwardly extending lip .or tongue, (shown in section in Fig. 3,) so that when the blade D is inserted in the socket H, as shown in said figure, the two parts h it will be forced outward, 'as will readily be understood. It is evident that when the blade D is inserted only part way in the socket H and turned the said socket will turn with it; but

. when the blade is forced home in the said socket it will be firmly held therein, and the socket will be wedged against the wall of the recess in which it is seated.

A great desideratum, also, with stone-cutters is to quickly get a correct miter-line when about to continue a molding on the end of a cornice or other stone after the molding has been worked on the face of the stone, or, as it is technically termed, returning the molding. To accomplish this with my invention, the slotted end of the blade D is inserted in thehead H at the proper angle relatively to the longitudinal axis of the bevel, as in Figs. 7 and 8, and the scriber E placed loosely on the said blade, the bevel being placed on the top member of the molding at or near the end thereof, so that the point of the pencil will be on the point from which the miter-line is to start.

The bevel and blade are held firmly in the position with one hand, while with the other the scriber is passed over the face of the stone, and, being permitted to ride freely on the blade,

, forward or backward, up or down, it will trace the miter-line accurately over the molded face no matter what the contour of the same. Should the size of the stone be such that the miter-line will be too long for the scriber to trace it from the position of the instrument at the top of the stone, the line is traced as far as the length of the scriber willpermit, and the instrument is brought down to the end of the line thus traced and the scriber again started to complete the line.

It is not absolutely necessary that the socket Hshould revolve or that it be divided, as an ordinary socket in the head will sometimes answer for holding the blade D. The revolving head is preferred, however, as it facilitates obtaining the miter-line when the miter is to be other than forty-five degrees, and difficulty is experienced, except by expert stone-cutters, in obtaining such lines.

In practice the pointer b and nut O are preferably within the plane of the sides of the bevel, so as not tointerfere with the easy working of the bevel on its side.

To ascertain whether a member of the molding is level in the transverse direction, I have provided the pivoted plumb-point I on the end of the bevel A. If a member is not correctin this respect, it is readily discerned when the bevel is placed thereon, the plumb-point swinging to the right or left of; the vertical center of the end of the bevel when the member is other than true-as, for example, at t in Fig. 8, where I have shown in full lines a member not true and in dotted lines the member as it should be.

In obtaining the lines for a straight molding, as in Fig. 6, the rod or straight-edge is usually employed, and while this is generally satisfaotory it will at times be found con.- venient to employ my improved instrument.

It will be understood that the invention above described is capable of many uses other than those above set forth.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with abevel-stock having a socket in its head and alongitudinal slot at right angles to the main slot formed by the two sides of the stock, of an adjustable sliding stem carrying a catch and carrying on its top a disk and pointer, and a slotted blade, substantially' as shown and described.

2. An instrument of the character described, comprising a bevel-stock constructed with a socket in its head and a longitudinal slot at right angles to the main slot, a sliding stem carrying a catch, and a slotted blade adapted to engage either the catch on the sliding stem or the head-socket, as required, substantially as shown and described.

3. An instrument of the character described,

head being wider at the bottom than at the top, a sliding stem carrying a catch, a sliding plate and pointer mounted on the stem, a slotted blade, and a scriber, substantially as shown and described.

5. The combination, with a bevel provided with a rotating head and a graduated sliding plate and pointer, of a slotted blade and a scriber, substantially as shown and described.

6. An instrument of the character described, comprising the bevel A, the sliding plate and pointer B b, and the head, H, of the blade D, and scriber E, substantially as shown and described.

7. The scriber E, having a swivel-socket, F, for the reception of a pencil, and having the inner surfaces of its sidesserrated, substan tially as shown and described.
