ALFRED T. SERRELL, OF NEW YORK, N. Y.

MACHINERY FOR MAKING MOLDING-S.

Specification forming part of Letters Patent No. 5,575, dated May 16, 1848; Reissued January 7, 1851, No. 187.

T o all wit-0m z' may concern:

Be it known that l, ALFRED T. SERRELL, of the city of New York, St-atevof New York, cabinet-maker, have invented and made and applied to use certain new and useful Im provements in the constructive arrangements and conjoint action of well-known mechanical parts employed with parts invented or improved by me for producing wood moldings, being formed with smooth surfaces that will no-t wrinkle when .painted or wetted and become what is termed woolly faced.

The means employed in said improvements enable me to make such moldings with a saving of materials in the conversion with a reduction in the amount of labor by which the publ-ic are furnished with such articles j rying ournal boxes 4, 4, taking the journals `of a shaft 5, whichr is prolonged outside the at -a less cost than the same can be made for by hand labor and with a uniformity of sectional shape and finish of surface that renders such moldings more effect-ive and acceptable in general use than others for which improvements I seek Letters Patent of the United States, and that the said improvements are constructively and substantially set forth and shown in the following description and in the drawing annexed to and makng part of this specification, wherevFigure l is a general plan of a machine l Fig. 4 is a sectional elevation through the line C, D, of Fig. l. The Figs. 5, to 10, inclusive represent the general manner in which t-he wood material is first sawed upy and the position and points of operation of the feeding rollers as they work on the molding strips as these are used to form lvarious patterns of moldings.

The same letters and numbers as marks of reference apply to the like parts in all the several figures, wherein E is the frame of wood or metal tted to support a bed of metal a, formed as a T the middle piece crosswise this is to be so shaped and fitted as to receive the working parts.

F, is a metal bed tted to slide lengthwise on the bed a, and secured by clamp screws 1, l, so as to adjust the feed roller close `to the rotary cutters, which screws go through slots in the bed a. The bed F, has on one end a fixed fence b, which is to guide the stuff into the machine by an adjustable spring 2, pressing the strip of wood against the fence b. The outer end of the bed F is countersunk to receive a metal or wood plate b1, let in so as to be flush with the surface and held in place by two small lugs on the inner end taking indentations in the bed F, and has at the outer end a set screw b2, going through the bed F which raises the outer end to any required height while the inner end remains even with the face of the .bed for a use. to be shown hereafter.

3, 3, are two pair of metal standards caris .formed of one or more Hat rings or disks with serrated edges -of diameters varying `with the depth at which each is to work, .cut :either beveling or stra-ight and keyed on ythe journal box has two lugs taking set screws m, to regulate -t-he point to which they shall descend and outside the boxes 4, 4, the shaft 5, kreceives two slings 6, 6, secured to the boxes 4, 4, and descending beneath the bed a, to receive an `adjustable cross piece 7, taking a lever and weight c2, on a fulcrum 9, on a standard on the bed a, the end of the lever receives a strap 8, which goesover a roller on the under side ofv the bed a, and serves to raise the lever and Weight G2, and yfeed roller and stop thefeeding of the material into the machine and is held by a pin going through holes in the strap 8.

The shaft 5, receives a pulley 10 with a band going to the double grooved pulley 03, which is sustained by the band on the pulley l0, and has a sling going to a lever and weight c4, on a fulcrum 11, on the frame E, the sling has over the grooves in the pulley c3, two screws 12, the points of which serve i to remove the dust and chips that may fall into lthe pulley grooves the band passesup in flush with the bed F, under the feed roller c1, and to allow a free motion to the roller (Z, the bed a, is hollowed down as shown in Fig. 2. A

The middle part of the bed a, receives a sliding bed e, going across the machine which is held in place by a clamp screw 15, in slots in the bed a, and is adjusted by a set screw 18, going through a lug 16, on the bed a, and operating in a lug 17 on the bed e. The bed e, carries at` each end a pair of metal standards el, formed as slides to receive sliding boxes 19, each with a lug on one side taking a set screw 20, going through a lug on the bed e, by this screw the sliding boxes 19, are adjusted vertically their tops being formed as a box 2, to receive a journal box e3, secured by screws going through slots formed lengthwise of the box. The box e2, carries a set screw 21, operating against the end of the journal box e3, which on the opposite side is bored out to receive a block or peg of hard wood a journal thus constructed in each pair of standards receives as a center in the block of wood in the thus made are beads 23, forming slides thaty receive t-he cutter tools 24, with the cutting edge so formed as to produce thev required shape of the molding when operating on the wood, the middle ofthe cutter has awslot 'running to the back of the cutter which receives a screw 25 this passes through a steel cap 26, which is set on outside the cutter 24 to take the strain. This scerw `25passes through the slot in the cutter 24, and into the block g, by this construction whenever any cutter has to be sharpened or replaced the screw 25, is to be slacked up suihciently to withdraw the cutter 24, which can be replaced or changed withoutdetaching the cap 26 or screw 25.

The bed a, carries beyond the cutter heads a second xed fence g1, by the side of which isa common molding plane h, of the pattern to correspond with that produced by the rotary cutters, fixed as close to the cutters 24, as convenient and has a hole bored through the sides near the center to receive a bar 27 which has a thread to carry a nut vsetting against one side of the plane h, one end of this bar is turned smaller with va shoulder on the outer end two sides of which are cut away which goes through a slot in a screw stud 28, so that on putting the shaft through the slot and giving it a quarter turn the remainder of the collar will hold it in place to be adjusted vertically by a screw 29, going through the upper part of the slot in the stud 28, or by turning the screw stud 28 when the bar is not in it, a slide 30 on the inner edge of the bed a, receive and hold the shaft 27, and allow of its vertical mot-ion and pressure is given to the plane h, by a weight 31 o-n the outer end of the bar 27.

Beyond this the bed. a, is hollowed down vto receive on one side three fixed slides z', `which are jointed near the outer edge of the bed a, to three similar slides 1, by hinges 32 which are connected together and sustained and adjusted by a screw 33, on the part i3, fof the bed a, and the bed a, is removed near the middle to prevent any substance lodging to choke the working of the sliding beds k,

Vthe iron to form the face.

To the under side of each of the beds k,

iand 702 is a strap or cord 40 attached which l,passes over a pulley 41, in the outer edge of the slide 761 or k2, and descending sustains a weight 42, each of which serves to draw both 'pair of beds 7c, and k1, k2, and k3, toward yeach other, which is stopped at any requiredv point by screw bars 37, with a nut on one Epart and a collar a short distance from the jother end going through holes in lugs 38 on ,the plane stocks 35, so that the planes will separate by the bar sliding in the hole but.

,will not `approach each other within a certain adjustable point by the collar taking the lug 38. Vhen thus constructed and adjusted for use, the material 0, is to be laid jon the plate b1, whichisto be raised to the proper height by the screws b2, and the stuff ,shoved under the feed roller c1, which oper- 'ating on the wood pressesit on to the bed which is not a straight line thus making the spring of the wood hold the end down against the operation of the rotary cutter 24, at the same time forcing it forward by its rotary motion the edges of the feed rollers taking into the strip to form the moldings in the parts to be removed by the cutters as Shown by the blue lines in Figs. 56, 7, 8, 9, and 10, forces it on against the operation of the rotary cutter which forms the wood into the required shape thence the molding passes under the fixed molding plane h, which is kept in its place and pressed down passes beneath, thence the strip'passes between the planes 36, the first two taking a rough shaving oil" each edge, the second two smoothing and the complete molding passes out by the guide fence 39, and is thus ready for use. The screw 33, operating under the slide frame 1, adjusts that by turning it vertically on the hinges 32, so that if the thick est edge of the molding is to be beveled at more or less than a right angle with its bed it can be done so without disturbing any of the apparatus.

The Figs. 5 to l0, show by red lines the general manner in which I saw out my strips for forming moldings as by this means considerable wood is saved in the conversion into moldings the sawing being effected by one or more diagonal cuts by a circular saw.

It will be further seen that by the formation and changeable adjustment of the feeding rollers they operate so as to stick into those parts only that are to be removed by the rotary cutters, by this means the new and useful effect is produced of saving material rst by cutting out two moldings from one strip but this alone would not be effective without feed rollers that act as shown by not bruising the part that is to remain and thus saving the amount that would otherwise be wasted by any feed roller operating equally all over the surface or partially on the highest part of the molding instead of the parts that is to be taken out.

I do not claim to have invented grooved feed rollers to force in the material to be molded. But I do not know of any previous machine, in which such a roller has been applied, of either of one or more rings or disks, that operate to feed the material into the machine, by contact with the part, that has to be removed by the cutters; neither do I claim the rotary cutter for forming moldings, nor a common molding plane, but I do not know of any machine, in which these have been combined together, with a means of maintaining an equal pressure of the plane, on the molding beneath. Therefore,

lVhat I claim as new, and of my own invention, and desire to secure by Letters Patent of the United States, is-

The application of the changeable feeding rollers 01, made as disks, or fiat rings, with serrated edges of varying angles, and changeable or unequal diameters, to feed in material, cut in varying or irregular sections, in combination Awith changeable rotary cutters, and changeable standing planes, to produce wood moldings, of different sizes, with smooth surfaces, from material cut or prepared in varying or unequal sections, for such purposes; the whole applied, constructed, and operating, substantially in the manner, and with the effects described and shown.

In witness whereof, I have hereunto set t my hand, this eleventh day of December, one thousand eight hundred and forty six. ALFRED T. SERRELL. Vitnesses:

Disclaimer.

To the Uommzssioner of Patents:

The petition of JOHN LAWRENCE, of the city, county, and State of New York, respectfully represents that he has, by assignment duly recorded in the Patent Office of t-he United States, become the owner for the term of siX years commencing on the first day of September, 1849, of the right for that part of the city of New York lying east of a line commencing at the south end of lVhitehall street, thence proceeding northwardly up the middle of saidstreet to its intersection into Broadway, up the middle of Broadway to the intersection with Chatham street, up the middle of Chatham street to the intersection with the Bowery, up the middle of the Bowery and by the railroad and Union Square to the middle of the Fourth avenue, and up the middle of the Fourth avenue to the northerly termination thereof, to certain new and useful improvements in machinery for making moldings, for which Letters Patent of the United States were granted to ALFRED T. SERRELL, of the said city of New York, dated on the sixteenth day of May, one thousand eight hundred and forty-eight. That said Letters Patent were afterward with the assent and at the request of your petitioner surrendered on account of a defective specification and thereupon a new patent for the same invention with a corrected specification was granted to the said ALFRED T. SERRELL dated the seventh day of January, one thousand eight hundred and fifty-one; that your petitioner has reason to believe that through inadvertence and mistake the claim made in the specification of said last mentioned Letters Patent is too broad including that to which the said patentee was not the first inventor.

Your petitioner therefore wishes to disclaim such parts of the said specification as indicate an intention to claim as new the combination of pressure or feed rollers with rotating or other planes or cutters, either for planing cutting moldings or any other purpose whether used for operating upon regular flat surfaces or upon regular plane surfaces more or less inclined.

Your petitioner therefore hereby enters his disclaimer to all that part of the claim in the aforenamed specification excepting to the combination of the rollers or rings econornizing the material and facilitating the operation, which disclaimer is to operate to the extent of the interest in the said Letters Patent vested in your petitioner who has paid ten dollars into the Treasury of the U. S. fagreeably tol the requirements of the act of Congress in that case made and prO- vided,

JOHN LAWRENCE. Witnesses;
