UNITED STATES PETER M. THOMSON,
OF NEW YORK, N. Y.
PLASTERING APPARATUS.
Specification of Letters Patent.
Patented Sept. 24, 1907.
Application filed February 7,1907. Serial no. 356,189.
Toall whom it may concern:
Be it known that I, PETER M. TnoMson, a subject of the King of-Great Britain, residing in the city of New York, borough of Manhattan, in the county and State of New York, have invented a certain new and useful Improvement in Plastering Apparatus, of which the following is a specification.
The invention relates to means for shaping the exterior surfaces of columns, balusters and analogous structures of plastic material, and the object of the invention is to provide a portable apparatus, easily applied and adjusted, and simple in construction and operation by which the shaping and finishing of such structures may be quickly and accurately effected.
The invention consists in certain novel features and details of 1 rrangement by which the above objects are attained, to be hereinafter described.
I employ two guiderings fastened one at the top and the other at the base of the unfinished column, each inclosing a traveling ring to which is secured one end of a striker-board or rod arranged to travel circumfercntially of the column and shape the plastic material applied thereon.
The accompanying drawings form a part of this specification and show a preferred form of the invention.
Figure l. is an elevation showing the apparatus in place on a plane cylindrical column. Fig. 2 is a plan view on alarger scale, partly in horizontal section, showing the top guide-ring applied to a column, the striker-board being omitted. Fig. 3 is a corresponding side view. Fig. 4 is a vertical section taken on the line 4% in Fig. 2, and Figs. 5 and 6 are similar sections on the lines 55 and 6-6 xespectively, in the same figure. Fig. 7 is an elevation showing the position of the striker-board in shaping a tapered column. Fig. 8 is a corresponding view showing the strikerboard shaped to produce a base-molding, dado-molding and cap-molding on a cylindrical column. Fig. 9 is an elevation showing a modified form of strikerboard. Fig. 10 is a transverse section on a larger scale through the striker-board shown in Figs. 1 and 7, and Fig. 11 is a similar view of the striker-board shown in Fig. 9.
Similar letters of reference indicate like parts in all the figures. v
A is the shaft of an unfinished column, which may be of wood iron, terra-cotta or other material serving to support the load and to be built or cored out and finished on the exterior surface. B B are the stationary guiderings considerably larger in diameter than the finished column, each in two semi-circular portions which may be similar, and joined by bolts B B extending through bosses 13 B cast on the abutting ends thereof. The guide-rings are of channel-iron shape in 7 section thus-providing an annular groove b open on i the interior of the ring. On the upper face of the up- I per ring and lower face of the lower ring are cast four swells B B tapped to receive radially-extending holding and adjusting screws ll- B having their outer ends squared to receive a suitable wrench, not shown, or, provided with heads or handles by which they may be turned, as will be understood.
C is one of the traveling-rings, made in halves and i joined at the ends by thumb-screws O C extending through overlapping lugs G 0 Each traveling-ring or annulus is received in the groove b of its guide-ring and may rotate freely therein, and each carries a swell G tapped to receive a screw D having its outer end squared and carrying at its inner end a swiveled jaw or clamp D in which is a clamping screw D The swell C of the upper annulus is on the under face and that of the lower annulus on the upper face so that both may be rotated without interference of the screws D D with the screws B B.
M is a striker-board or rod, similar to a straight-edge, held at the ends in the clamps D and thus moved 'circumferentially about the shaft of the column. The working edge is preferably horsed or protected by a strip of sheet metal N adapted to produce a smoothly finished surface on the plastic material supplied on the exterior of the shaft. i
In using the apparatus the two halves of theupper guide-ring, each containing one segment of the traveling-ring, are applied to inclose the shaft of the column and joined by the bolts B and thumb-screws C, the lower rings are similarly applied and joined and each guide-ring is then carefully leveled and adjusted circumferentially to the axial line of the column by manipulation of the screws B B. The striker-board is then introduced and secured in the clamps D D and the screws D D turned to bring the inner or working edge of the board parallel with the finish-line of the exterior of the column but preferably about one-half inch within such line; coarse material, as mortar, is then laid on the shaft and the board traversed circumferentially about the shaft until the column is built out.
The screws D D are then again turned to draw the working edge of the board to the finish-line and the finishing coat, as plaster, applied to the column and the board traversed as before untiifinished to a smooth surface. The apparatus is then removed for service on another column, and the base and cap of the column applied in the usual manner after the finishing coat is sufficiently hard. The surface produced is true and polished and no hand troweling or slicking is required.
Each annulus C is preferably equipped with antiffiction devices as the horizontal rollers (J C in equally spaced holes 0 and projecting slightly above and below the annulus to match to the smoothly finished uppe and lower interior faces of the groove 12, and the guider rings are also each provided with rollers B B in openings b b in its exterior wall in contact with the periphery of the inclosed annulus.
The rings are thin and may be placed close to the ceiling at the upper end of the shaft and near the floor at the lower end so that nearly the whole height of the column may be treated. It will also be noted that all the segments for the upper and lower guide-rings are cast from one pattern, and that but two patterns are required for the segments of the traveling-rings.
By properly adjusting the screws D D the board may be inclined to finish a tapered column, as indicated in Fig. 7, and an annular portion of a base, cap or dado molding or bead may be formed by similarly shaping the working edge of the board as in Fig. 8. The surface of an ornamental baluster may be formed in like manner.
Fig. 9 shows an adjustable board comprising two strips M M laid face to face and having holes at receiving bolts M by which the length may be varied to suit columns of various heights. The working edges are shown as beveled and protected by metal coverings N Other modifications may be made in the forms and proportions without departing from the invention.
Although I have described the apparatus as adapted for finishing columns, it will be understood that it will serve successfully in the production of newel-posts and like structures of circular section.
The working edge of the board may be curved to finish columns having an entasis or swelled contour.
I claim:-
l. In an apparatus of the character set forth, guiderings each in two portions constructed to inclose the shaft of a column, and means for securing said guidea-ings to said shaft, traveling-rings guided by said guide-rings, and a striker-board carried by said traveling-1-ings.

3. In an apparatus of the character set forth, guiderings each in two portions constructed to inclose the shaft of a column, screws extending radially of said guide-rings for securing the latter to said shaft and adjusting them relatively to the axial line thereof. an annular interior groove in each of said gilidel'illgs, a sectional travelingring received in each groove, a clamp on each of said traveling-rings means for adjusting said clamps radially, and a striker-board held by said clamps.
-.i. In an apparatus of the character set forth, guiderings each in two portions joined at the ends to iuclose the shaft of a column, screws extending radially of said guide-rings for securing the latter to said shaft and adjusting them relatively to the axial line thereof, an annular interior groove in each of said guide-rings, a travel lug-ring received in each groove and consisting of two portions joined at the ends, a clamp on each of said traveling-rings, means for adjusting said clamps radially, a striker-hoard held by said clamps, and anti-friction rollers mounted in said guide-rings and traveling-rings.
In testimony that I claim the invention above set. forth I aflix my signature, in presence of two witnesses.
