To @ZZ whoiit t may concern.:

Beit known that I, CHRISTIAN E. SECKFORD, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in a Combined Molding, Ornamenting, and Graining Machine; and I do hereby declare the .following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form a part of this specification.

The object of my invention is to facilitate the finishing of those molding-strips employed in making picture-frames and various other fancy and useful articles, the finishing here alluded to being the application of plastic ornaments to such moldings and in some cases the graining of their surfaces. To accomplish these two independent results, I apply to the delivery end of a molding-cutting machine an ornamenting or die wheel or disk, a fount that contains a plastic material, and a feed device for expelling the material from said fount and discharging it upon a molded strip at a point in front of said wheel. Furthermore, as said strip advances the plastic material is spread thereon, after which act the ornamenting-wheel comes into service and imprints its pattern on said material, the wheel being turned wholly by frictional contact with said molding; but a pair of such ornamenting-wheels may be used and have provision for setting their respective shafts at different angles in order that said wheels may operate simultaneously on dat or beveled surfaces of the same strip. After one or two rows of ornaments have thus been applied to l a molding a graining-roller may be brought into action, its turning being also effected by frictional contact with the advancing strip, as hereinafter more fully described.

In the annexed drawings, Figure l is a lon-` gitudinal section of one form of my machine provided with a single ornamenting-wheel. Fig. 2 is a transverse section of a machine provided with a pair of ornamenting-wheels, one of them being vertical and the other inclined and the graining-roller omitted. Fig.

is an enlarged horizontal of one of the ornamenting-wheel shafts and its accessories. Fig. i is a plan of a machine adapted to use a pair of such wheels, although one of them hold said standard in any desired place.

the action of two different forms of ornainenting-wheels. my invention. y A

Referring to Figs. l and 4, A represents a Fig. S is a modification of portion of the rear end of any approved form of machine for shaping a wooden strip by means of ordinary molding-cutters, and d d are guides that confine said strip to a proper path as it is delivered from said machine, to which latter there is securely fastened, as at a, a table or bed-plate B, having a transverse guide I), whose opposite edges are undercut, as seen in Fig. l. Adapted `to slide along this guide is the base C of a standard or housing D, a set-screw c serving to E is a screw arranged vertically within said standard and having at top a crank or hand wheel e, the object of this screw being to raise or lower a slide F. This slide engages with the standard D in the manner shown in Figs. 3 and 5 and has near its lower edge a circular pit f to admit a short cylindrical lug g project'ing horizontally from the rear surface of a box G, the latter being provided with a curved slot g", concentric with said pivot g. g" is a bolt traversing said slot g and engaging with said slide F. 9" is another bolt tapped in said box and serving to hold in place a fixed or non-rotatable shaft H, having at one end a head h, bearing against an annular iiange of a sleeve I, one or more washers e" being inserted between said sleeveand box if occasion requires. (See Fig. 3.) .I isa collar secured around said sleeve by a screw j.

K is a metallic wheel or disk the periphery of which has any desired arrangement of designs, inscriptions, orornaments either raised from the wheel or `cut therein, said wheel being notched at 7L to admit a pin 1l", projecting laterally from the annular flange t'. W'heel K is clamped tightly between the iiange z'andcollar J, and by means of the notch 7a and pin i the three members I J K turn together around the non-rotatable shaft H. Consequently the sleeve affords an eX- tended journal-bearing for said wheel and IOO compels it to run perfectly true and without any tendency to cant over at either side, or,

in other Words, it is always perpendicular to the aXis .of shaft H.

b' b are angle-gages capable of being adjusted transversely upon `the table B, and L L' are guides having at their front ends shoulders Z, that bear against said gages in the manner seen in Fig. 4. The rear ends of these guides are provided with adjustable Scrapers l' Z', so shaped and applied as to clean ot'f all superliuous composition from 'a piece of molding as it is passed through the machine. r v

M is a tie-rod unitingthe upper portions of the standards D D', and fm m' are bolts that retain said standards in place after they have been properly adjusted along 'the guide b. The rear grooves d d' of these standards are furnished with an upper pair of adjustable anglebrackets N N' and alower pair ot simivlar devices N" N'", each bracket being longitudinally slotted, as seen at O in Fig. 5, and being retained in place by a bolt o. The heads of these bolts traverse said grooves d d'. Iivote'd to the upper brackets N N' are swinging 'arms n f n', whose free front ends carry a rod P, provided with one or more spongespp', which are saturated with water, so as to keep the ornamenting-wheel constantly moist and prevent-the plastic composition adhering to it.

w w are smaller rollers that may be used to support the strip after it has passed out beyond the Scrapers Z Z.

The operation ofthe single-wheeled machine (seen in Figs. 1 and 4) is as follows: The gages b' b" and guides L L' must first be arranged accurately in line with the guides lct a' of the molding-machine A in order that the Wooden strip V may pass directly onward without any personal attention, andthe standard D and shaft H must be so adjusted as to cause wheel K to act in the exact place Where the plastic ornaments are to appear on said strip. In the present case this strip V is supposed to be perfectly flat on top and bottom, and its upper surface has a rectangular `groove n cut in it by the molding-machine,

the groove being near one side of said strip.

'This strip is shown on an enlarged scale in Fig. 6, reference to which illustration indi cates that the wheel K tits snugly within the groove t, as it is desirable to turn saidwheel solely by the contact' of its sides with the walls of said groove. The founts or hoppers R T being charged and the sponge@ saturated with Water, the molding-machine is started, thereby causing the strip to pass from the guides a ct' and enter lthe guides L L. As soon as the molding passes under the nozzle 25a su pply of plastic composition is discharged upon said strip in close proximity and in front of the wheel K. A still further advance of the molding causes this wheelto 'come into .f action and impress its ornaments on the plastic composition, the moisteued surface of said wheel preventing any clogging or choking up E of the machine. the molding is shown in Fig. 4 as extending 3 from t" to t". 1 rives at J the rear ends of guides L L their l Scrapers l' Z' come into service and at once re'- mov'e from the strip all superfluous composi- This ornamented portion of By the time the molding artion, the cuttings falling down at the end Vof table B and not interfering with any of the operative parts of the machine. After the molding is thus cleaned it is iinally subjected to the action of the roller Q, the result being the gra-ining of the flat upper surface of said strip, as seen at fu". Consequently the strip When it leaves my machine is ornamented, scraped clean, and grained Without requiring the least personal attention; but in many cases the roller Qis not used, as graining is not imitated on all moldings'. .To render this roller inoperative, the bolts coupling the arms it" n'" to the brackets N" N'" are first unslackened, and then said arms are swung up until said roller is s ome distance above the level of bed-plate B, where it is held by again tightening said bolts.

From the above description it is evident the finishing of thestrip, Whether simply orna- 4 a second strip, and the latter by a third one,

and so on continuously while the sticker is in operation.

The above describes what I call my singleaction machine, because it uses only one ornamenting-wheel, but a double action may be afforded by a pair of such wheels in the following manner, reference being now made to Fig. 2. This illustration shows that a secondary wheel K' is applied to the other shaft I-I', and the latter is adjusted within the box G and held therein by a bolt g'", said shaft in this view being inclined, so as to cause said wheel to act on a beveled surface of the molding. This inclination is obtained by loosening the bolt g" and then swinging the box G' on its pivot g' until the proper angle is reached, and then said bolt is again tightened. Hence it is apparent the boxes G G' can be set so as to cause the Wheels K K' to run upon horizontal surfaces of moldings, or either one or both of said boxes can be so inclined as to enable said wheels to act on beveled faces of astrip.

In the construction heretofore described the ornamentingwheel is driven by either one or both sides coming in contact with the walls of a groove that receives the composition; but as seen in Fig. 7 the entire surface of the strip V' is to be ornamented. In this case the width of the wheel K must be equal to `that of said strip, and rings or disks 7a 7c" must be so fastenetlito said Wheel as to bear against the sides of t-he molding, and thereby afford the friction necessary to turn said wheel.

My invention may be further modified, as seen in Fig. S, Where the roller that supports the molding is fluted at IV', so as to drive a gear-wheel X, secured to a shaft fr, having at one end a center a', supported upon abearing Y, carried by the box G. The opposite end of this shaft has an interiorly-threaded socket fr", engaged with a hub projecting from a wheel K", that turns freely on a shaft II", said shaft being slotted at 7L' to be adjustably applied to the other box G'. By this arrangement a positive turning of wheel K" is effected and the frictional feed is dispensed with, although the wheel IV' is itself driven by the strip or molding; but care must be taken to have the pitch-circle of gear X exactly equal to the circumference of said Wheel. If this precaution is neglected, the wheel cannot produce perfect ornaments on the strip, but will spread the composition unevenly and tear it apart in places.

I have described the bed B as bolted to the plate A, as this expedient enables my attachment being readily fitted to molding-cutting machines generally; but in building entirely new machines said bed B may be integral with said plate A. Finally, although this bed B is shown in close connection with the molding-cutter A, it is evident said bed may be separated therefrom by a greater or less interval, provided means are afforded for en abling a strip to be fed from said molding cutter into my ornamcnting mechanism without rehandling by an attendant.
