IMPROVEMENT IN MACHINES FOR MAKING MOULDINGS` TO ALL WHOM I'I MAY CONGERN:

Be it known that I, NICHOLAS JENKINS, of the city and county of New York, and State of New York, have invented certain new and useful Improvements in Machines for Panelling and Variety Moulding; and I do hereby declare that the following is a full and exact description thereof.

I will first describe what I consider the best means of carrying out my invention, and will afterwards designate the points which I believe to be new, reference being had to the two sheets of drawings, which representl the novel parts of my machine with so much of the other parts as is necessary to indicate their relations thereto.

Figure 1 is an end View of the machine.

Figure 2 isa front view of the main portion of the machine and a cross-section of the templet and of the wood which is being operated on. v

Figure 3 is a central vertical section through the lower end-of one of the cuttingiarbors.

Figure 4 is a horizontal section on the line S S in fig. 3, as seen from below.

Figure 5 is a central Vertical section showing another form of the cutter and its connections.

Figure 6 is a plan view seen from below.

Figure 7 is a top view ofone form of my templet.

i Figures 7 A and 7 B represent cross-sections of the parts detached from each other.

Figure 8 is a top View of the wood lafter it has been panelled.

Figure 9 is a cross-section of the same; and Y Figure 10 is a cross-section showing the piece which is tted in the table to adapt the machine for variety moulding.

Similar letters of reference indicate like parts in all the figures.

A is the foundation or the main framework, and A1 is the xed portion of the head supported firmly thereon. Bl B are the arbors, mounted in carriages O1 C2 which are adapted to move vertically n dove-tailed channels as is usual in this class of machinery. The ordinary loose pulley above, with the driving-pulley and belt, the latter capable of being shifted from the loose pulley B3 on to the pulleys mounted on the upper extremity of the respective arbore, B1 and B2, are all of the ordinary construction, and are operated in the ordinary manner. D isa cross-traversing carriage adapted to slide horizontally in a head, w, which is adapted to move vertically in the head A1, as represented. E is a movable table on which the work is operated in either. direction horizontally by the aid of the cranks, as represented. The operator holds the two cranks, onein each hand, and by turning one or both simultaneously in one direction or the other, moves the carriage E in any direction desired, according as is required to produce the proper pattern. This portion of the operation is identical with that of many other approved forms of panelling and variety moulding machines. El E2 are clamps operated by the thumbscrews e1 e, and adapted to press upon and firmly confine the templet and the wood which is' to be operated upon. G is the main or exterior templet; G is a templct adapted to fit accurately within the templet G. There may be still other templets fitting within the templet G', if preferred. The inner and working edges of these several templets may be alike in form and proportion, or may be very diverse, as preferred. But the thickness of the several templets is equal, or about equal, and the exterior of one corresponds with such accuracy as to it immovably within the interior surface of the templet or portion of the templet which surrounds it.

In operating my machine the exterior templet Gr is applied first upon the wood H, and is firmly clamped by the clamps El E2. After the cutters have traversed quite around the interior of these templets, and produced a. corresponding panelling cut in the wood II, the cutters are lifted and the next succeeding templet G is dropped into place. The same or different cutters are now applied and traverse around the interior ,edge of the templet G. c c are notches formed in the sides of the carriages O, and adapted to sustainthe latter and their connec" tions by a hook received therein. I, in figs. 1 and 2, is the main body of my hook; it is adapted to turn on the pivot z', and is acted on by the spring J tending to force it into contact with the carriage C. K is a' movable hook-,piece mounted in the main body I; it is traversed up and down in the latter/by means of 'the thumb-screw L. By turning this latter in one direction or the other` the hook-piece K is raised and lowered with the greatest accuracy, and adjusted as inely as may be required, while, by simply pulling the entire body I and its connec tions away from the carriage C, in opposition to the gentle' force of the spring J, I able to' liberate the carriage C, and to raise and lower it immediately so as to shift the hook into the next notch above or below, or to raise or lower it to any great extent desired. I have represented only one of my improved hooks. Both may be silch in practice. M is a hand-lever turning on the pivot m, and connected to the sliding head D and C so as to raise and lower the latter with great facility. Nis a lever, turning on the pivot n, and actuated by the coiled springN so as to hold its cutting edge in contact with the transverse sliding-head D.' There are two notches in the latter which are adapted to receive this lever N, and hold the transverse-sliding head D stationary when one of the shafts or bevelling-arbors B is exactly in line with the loose pulley which carries a belt above. This part of the mechanism is analogous to that in common use in this class of machines.

I will now describe the provision for raising and lowering the cutting parts 'simultaneously and adjusting them at diii'erent heights. v

Wis a vertically-traversing carriage; it is guided on upright vways A2 formed on the fixed head A1. This carriage W carries the -brackets which support the loose pulley,.before described, .and also supports the several working parts which are driven by the power derived from the belt. The dove-tailed horizontal grooves Aor ways provide for the lateral traverse of the carriage D. The lever N is pivoted upon this vertically-traversing carriage IV. This mounting of so many ofthe working parts upon a single vertically-traversing carriage gives very important advantages which will be readily recognized by those familiar with this class of machinery. It carries the horizontal carriage D and all its several immediate connections, also the lever N, also the stout upright arm A3, which supports-the loose pulley B3, several times above referred to, also the belt-shipper and the friction-spring and guides which hold it in the required positions. The means of adjusting this carriage -W in the required positions up and down on the slides A2 are partly indicated in the drawings, and thereinainder. will be readily understood. X is a hand-crank, which turns a shaft, 1:, which carries a small spur-wheel, indicated in dotted lines in fig. f2. This wheel meshes into a rack en the face of the upright A1, and by turning the hand; crank X the entire carriage W is 'moved up and down. In order to hold it in any required position, and yet allow it to be adjusted readily and rapidily without the necessity for liberating any ordinary pawls, set-screws, or the like, I provide the springY which is connected at each end to the carriage W, and presses its coils,near the centre of its length, against the notched wheel represented on the shaft X. This serves as a'kind of springpawl by catching in the several recesses or notches in this wheel. It holds with suihcient force therein to support the weight of the parts, but not with so great force as to prevent the crank X from being readily turned in either direction when required. i y y i I will new describe the peculiarity of the cutter-head and its connections. O is a brace, bolted upon the under side of one of the carriages Cl or C2. Both may be alike. I will describe simply that which is attached to the carriage Gl. The lower end of the arbor B* is threaded, as represented in iig. 3, and matches a female screw on the interior of` the shell or hea-d P. The cutters, carefully worked to the proper form to produce the panelling desired, are bolted upon the squared parts of this latter shell in the manner represented. Figs. 6 and 'i' show an adaptation of the arbor B to receive the stem of the cutter internally. This construction may be used in connection with the one shown Vin fig. 3, and is, it will be perceived, so represented. Fig. (i shows the same construction as is shown in g. 3, but with the further adaptations now to be described. Q is a pinvo` cast steel adapted to tit into a corresponding socket bored in the lower end of the arbor, which we will continue te describe as B1. It is confined and released therein by the pinching-screw represented, and is adapted at its lower extremity to remove the Vwood tovth'e desired pattern. V is a screwed thimb'le, having a projecting lip `or iange adapted to form a shoulder as it is screwed up into a hole in the brace O, which is threaded to receive it. The lower extremity of this thimble V is slender, and encircles the pin Q without actually touching it so as to create any appreciable friction. This extension V1 is turned perfectly round, and is polished nicely, and forms a surface against which the several templets, above described, may bc successively traversed in panelling by the aid of my machine. It will be perceived that this thimble V rises and sinks with the cutter and is always in immediate proximity to the cutting portion. R, fig. l, is a pin, which in its present position performs no function except that of being held and holdingthe ring T against being lost. Its use is to t into the hole represented in dotted lines in the table E, and in the under table F, and in the main body A, so as to hold all these parte in a xed position when desired for variety mouldi'n My device for adapting the machine to produce variety mouldings is very simple and easily described. T is. a; ring of metal, carefully turned and polished. It ts nicely in the corresponding circular recess, indicated in dotted lines in the table E. This recess is so related to the holes which receive the pin It that it is exactly in line with the loose pulley B3 when the table E is locked in position. In applying my wood for variety moulding I apply.y it upon the top ofthe templet, holding it by spurs thereon, as is common in some of the best machines of this class. On pressing the templet with the 'wood thereon against the ring T, and moving it around the cutters, reduce thc wood to the corresponding form in the same manner as with other varetymoulding machines, except that the work is performed bythe same machine as performs the panelling above described, with this very slight modification. There may be two or Amore of A,these guides T, if'desired.

Some of the advantages due to certain features of my invention may. be enumerated asfollows:

First, by reason of the fact that my adjustable hookY Iz K is constructed' lwith* a' capacity for delicate adjustment'of the part K up and down and arraugedutojopera'tein connection withthe notches'in the slidingcarriage C,V as. represented, 'I am able to graduate the deptheto which thecu-tters act with extreme nicety, while the carriage is secured andreleased with all the easeand rapiditypossiblevwith other and ordinary hooks.

Second, by reason of thefact that the guide V is round, and is mounted concentric to the arborof the cutte'r, am able to control the action of the cutter so as ytitftraverse it along the edge of a templet without subjecting the guide or the tmplet toany friction due to the lrotary motion.

Third, by reason of the fact that my .ring T is' adapted to be tted at pleasure in the recess in thebed E.

and to be so Aheld there exactly in line with the cutter above, I am able to manufacture variety monldings with the same machine as is employed for panelling, and with very little trouble or expense in the changing of the machine from one condition to the other.

Fourth, by reason of the fact that the templets G t over instead of under the wood H, and that the :machine is provided with meansrfor firmly holding both upon the table E, and for moving the latter in all directions, as required, I am able to executctlarge Work with a-small machine7 and to guide the material vith great certainty and ease. Y

` Fifth, by reason of the fact that my templcts GG', Sec., are fitted accurately one within the other, as represented, I am able to execute a succession of operations upon these-me piece of wood H, by dropping in the successive inside templets and changing the cutters, if' necessary, 'by running the cross-head D across or otherwise without liberating and readjusting the-wood o r the original external templet; I am, therefore` able to secure a mathematical exactness of position without any labor or care.

Sixth, by reason of the fact that the single head w carries the entire cross-head D and the connected paris, so that it is capable of'being raised and lowered with ease to any extent usually required Without requiring any adjustment of other parte, I am able to operate on dilferent thicknesses of wood properly and with equal effect without a moments delay and withoutl deranging any of the varied capacities and nice adjustments of the machine. I

Having now fully described my invention, what I claim as new in panelling and variety moulding machines, and desire to secure by Letters Patent, is as follows: l
