. Specification of Letters Patent. y Patented March 16, 1,909.v

Application led September 30, 1907. Serial No. 395,245.

To all whom it may concern.'

Be it known that l, WILLIS D. EITEL, citizen of the United States, residing in the city.

and county ol San Francisco and State or' California, have invented new and useful lmprovements in Plasterers Miter Cornice- Molds, of which the following is a specificaton.

My invention relates to a device which is designed for making interior cornices in rooms or buildings, and is particularly designed for making the miter joints at the interior angles of the rooms.

lt consists in the combination of arts, and in details of construction which wi l be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a plan view of the device. Fig. 2 is a side view of the same. Fig. 3 is a view showing the tongue, and one member of the mold withdrawn with relation to the other.

It is the object'of my invention to provide a cornice mold, including two members having edges of such contour as to form the desired cornice upon the vertical wall and the ceiling; and these members are mounted upon a base which is movable horizontallyT along the wall so that the edges of the mold plates will form the desired outline in the plaster which has been previously applied over the surface where the desired cornice is to be made. These moldeplates are located in a plane at right angles to the base and bisecting the right angle at the corner of the base, and are movable with relation to each other, so that after the cornice has been formed, they may be withdrawn from the fresh material without destroying its contour.

My mold consists of the plates A and B, the outer edges of which are so fashioned as to impart to the plastic cornice the desired design or coniiguration, when said plates are moved over the cornice.

The base plate C is shown as having two meeting edges forming a right-angle with each other, and to said base plate is iXed the plate A which stands vertically upon the base plate, as shown in Figs. l and 2.

The part B is supported vertically above the part A and it is slidably mounted in guides D which are held in place with relation to the base C by braces of any suitable description, as shown at 5 in Fig. l, and indi cated in dotted lines in Fig. 2.

The adjacent edges of the plates A and B f form straight lines which diverge from kthe left, as shown in Fig. 2, toward ythe opposite lower side of the Vbaseyand between these edges a wedge-shaped piece 2 is slidable, said piece having a handle Gby whichr it may readilybe withdrawn. i

The edge of the base C is cut away at the point where the handle approaches it, so that the handle `and the plate may kbe pulled downwardly.substantially ink a line/central oi the tongue 2. a

'When the tongue has been pushed into position, the end 2a will coincidewith the cur` vature of the inner angleof the cornice, and the two plates A andB will thus be held in position to form both the wall and ceiling out# f line of the cornice, in the samemanner as if j y they were formedin onek piece.-

In the .operation of forming the cornice, the base C is placed with one side against one of the walls Vof the room, rand being moved along horizontally with the cornice outlined edges of thev plate in contact with thejcornice material, the latter will be shaped to correspend with the outlines of the edges a of the plates 5 the movement being preferably away from the meeting angle of Athe walls. other edge of the basef may then be placed against the other wall, the cornice-forming edges being again placedin the angle, and by moving the base alongthis other wall, the other side of the cornice will be outlined.

The position of the mold-plates being diagonal to the line of movement, will make a smooth drawing strik/e, and will corres ondingly finish the curves; The angles` an curvatures of such a cornice are such that it will not be'possible to remove the device directly, and it is therefore necessary to with-' The f draw one of the plates substantially at right l One end of the lever' 3 is pivoted to the plate A as shown at 9, and the other end is pivoted at l0 to the end of a link 1l the opposite end of which is pivoted to the sliding wedge2 as shown at 12. f y

' 13 are guides iixed to the plate A, and eX- tending upward along the sides of the wedge 2 so as to form a channel in which said wedge is slidable. "When the wedge is inserted 'between the plates A and B, and with them forms a complete cornice mold, ,the link 1l stands substantially at right angles with the upper edge of the wedge 2, and when the wedge is withdrawn, this link turning about its pivot point 12, acts upon the lever arm 3 to pull it downward, and this acting through the link 4 upon the plate -B pulls it down in a vertical plane so that it will be Withdrawn entirely from that portion of the cornice'which it has formed. It is then possible to withdraw the plate A in a horizontal plane without marring the cornice.

The relative .position of the plates when the wedge has been withdrawn, is shown in Fig. 3, in which the normal outline of the plates is indicated in dotted lines.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A cornice mold comprising a base plate, a mold plate arranged perpendicular to said base and having one edge shaped'to form a mold for a portion of a cornice, said edge being iiush with an edge of said base plate, a movable plate located above and Ain the same plane with said mold vplate and having an edge shaped to form the mold for the remaining portion of the cornice and arranged to form a continuation of the above-mentioned edge of the mold late, and means to separate and hold the vp ates while forming the cornice, and to contract the mold to allow it to be subsequently removed. Y

2. A cornice mold comprising a base plate, a mold plate arranged perpendicular to said base plate and having one edge shaped to form a mold or a portion of a cornice, said edge being flush with an edge of Ysaid base plate, a movable plate located above and in the same plane with said mold and having an edge shaped to form the mold for .the re.-y maining portion of the cornice and arranged to form ka continuation of the above-mentioned edge of the meld plate, and a wedgeshaped member slidably mounted between the adjacent edges of said mold plates to separate and hold the plates while forming the cornice, and to contract the mold ito allow it to be subsequently removed.

3. A cornice mold comprising a base plate,

having two edges meeting at right angles, a mold plate arranged perpendicular to said base plate and having one edge shaped to form a mold for a portion of the cornice, said edge being substantially `flushrwith an edge of said base, La movable plate located above and in the same plane with said mold plate and having an edge shaped to form the mold for the remaining portion of the cornice and arranged to form a continuation of the Vabove-mentioned edge of the mold plate, a wedge guided and slidable between the adjacent edges of the mold plates, and means by which said wedge is operated to move the second plate vto or from the first plate in a substantiallyT Vertical plane.

4. A cornice mold comprising `a base plate having two edges meeting at right angles, a mold 'late'arranged perpendicular to said base p ate and having one edge shaped to form a mold for a portion of the cornice, said edge being substantially iiush with anedge of said base,a movable plate located .above and in the same plane with said mold plate and having an edge shaped to form the mold for the remaining portion of the cornice and arranged to form a continuation of the above-mentioned edge of the mold plate, a wedge guided and slidable between :the adjacent edges of the mold plates, a lever pivoted to Vthe stationary plate, and links connecting said lever with the stationary plate and with `the wedgerespectively.

5. A cornice mold comprising a base late, having two edges meeting at right ang es, a mold plate arranged perpendicular to said base plate and having one edge shaped to form a mold for a portion of the cornice, said edge being substantially flush with an edge of said base, a movable plate located above and in the same plane with said mold plate and having an edge shaped to form the mold for the remaining rportion of the cornice and arranged to form a continuation of the above-mentioned edge of the mold plate, a wedge guided and slidable between the adjacent edges of the mold plates, a lever having one end pivoted to the iiXed plate, a link having yone end pivoted to the lever intermediate of its length, and the other end pivoted to the movable plate, and a link connecting the opposite end of the lever with the s idable wedge.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIS D. EITEL. Witnesses:
