To all whom u may concern:

Be it known that CHAUNOEY O. CROSBY and' HENRY KELLOGG, of Milford, in the county of New Haven and State of Connecticut, have invented a new and useful Machine for Producing Folded Trimming; and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent in-F- Figure 1, a perspective view of the whole machine; Fig. 2, a vertical section through the same from frontA to rear,.Fig.3, aperspective detail of folding-blades, delivering apparatus, 8vo. j, Figs. 4 and 5, 'details in per spective; Fig. (5, a section through the dischargingjaws; Fig. 13, a development on the plane surface ofthe cam j; Fig. 14, a develop- Y ment of the cam l1, and an elevation of the cam Z6, showing i7 projecting fre i it; Fig. 15, an elevation `of cam i3 Fig. 16, a develop ment of cam e3; Fig. 1i, an elevation of cam These `plans and developments, and the pointmarked al'. upony them, are all in the same plane, passing through the shaft upon which they are all mounted, and the other iigu'res are of details ofthe machine orrepresentations of the products thereof, which will be referred to hereafter. t

The material to be actedfupon by the machine is tape-braid and similar articles, or

machine folds suchstrips so as to resemble gimp or plaiting, and sews the ,folds down so as to preserve. the folding given by the machine.

The machine consists essentially of a delivering or introducing apparatus', a folding` apparatus, a stitching mechanisn, and a discharging apparatus, and, in its most perfect form, also conta-ins an assistant folder or preparer. i

The nature of our invention consists in ism into a complete machine, and also in various subfcombination's thereof, which perform certain operations upon' the material being acted upon, and also in certain peculiarities of construction of parts of apparatus, substantially such as are hereinafter described.

The machine herein described, which embodies our invention, is mounted on a table,

da a, which supports journals for the main to thebed-plate. -Th is tubfe has secured upon, it-a ratchet-wheel, d2, and attached to itsv lower end amouth-piece, which consists of a metallic gutter, al, with aspring, d3, pressing into the bottom of the same.

The springend the gutter-piece are attached toa block, d5, which is pivoted at d6 to thetube. This; block is slotted, and tape can pass from the reel -down through the tube, thence throngh the slot in the block, and, finally, out between the gutter-piece and the spring, the latter makinga slight resistance to the delivery of the tape. The mouth-piece, as a whole, can be eanted. upon the axis of the block, so as to carry the tape it is delivering away from the axial line of the tube, and this canting motion is derived from a stationary' cam, d?, (shown in detail in Fig. 7,) the protuberances of `which act upon arms d attached to, or making part of, the'slotted block d5.

In the precise machine described, the tube is to receive an interrupted revolving motion, which is im parted to it by means of a ratchet or dog, e, mounted on a lever, e, pivoted at e2.

The tail of this lever is forced to vibrate by' the combined agency of a cam, e, (see Figs. 16 and 19,) and a springattached to the lever,

and to any convenient vstationary part of the' machine, the spring forcing the lever against the cam. This spring, in order to avoid complexity, is not represented in the drawings. t

As thus far described the tape-reel would receive an interrupted rotating. motion; but as itis heavy, (when loaded with tape,) we find that it is more advantageous to apply the 'bobbin-collar f 3 loosely upon the tube to attach to'fthe collar a small. cog-wheel, F, (see Fig. 5,) and to cause this wheel to revolve un-I without the altcrna'testopping and starting due to the action of `a, ratchet and pawl; but even when it is so moved the assistant folder is still to be. actuated in "substantially, the manner before described.

This revolving of the'bobbin or reel upon the axis of `the tube is to prevent the tape from twisting as it is folded, and the canting and revolving motion of the mouth-piece is` to aid in folding the tape, or, in other words,

to prepare it for folding, and-the mouth-piece moving substantially as described, is the assistant folder, while the reel revolving on an axis other than its own, so as to deliver the tape'without a twist, or to take out turns that are pnt in the tape by the folding apparatus.

In making trimming, shown in Figs: 21 and V22, the material is turned one-half round in forming each successive point; hence the ne! cessity of turning the reel. which carries the material one full revolution -toy every two points; butin forming trimming with points upon opposite 'sides,"as in Figs'. 23 and 24, the one-half twist given to the material in forming the point upon one wil1\be takenfont in l forming the point upon-the opposite side;

therefore this rotating of :the material is-not required for all kinds of trimming.-

Below the mouth-piece lies the folding apparatus,which, in the present machine, consists of three folding-blades, l, 2, and 3. Theseblades are made of thin smooth sheet metal, and blade 2 is attached to :t slide, g, 'moving in proper guides in the bed-plate. Its further end g2 may be provided with afriction-roller, which. by means of a spring, g4, 'attached to the slide and some stationary part of the machine, is caused to press against a cam, g3, (see Fig. 8,) upon the main shaft; arevolution of the shaft will therefore cause the folder to reciprocate. This folder is springy or attached to its slide by a spring-connection, andhas brazed or otherwise attachcd toit af-wire or rod, g5. Alongside of the slide and secured to the table is a cam orwedge, g5, having its thin edge pointing toward the main shaft. By means of this rod and Wedge the blade 2 is lifted as it recedes backward and `near the Aend of its backward motion, and by backward We mean away from its mouth-piece. The bladell is also metallic and'springy, and isattached to a stock, h, to which is pivoted la lever, h1. This lever is pivoted upon a projection, h2, from a slide, h3, and the end of the lever rests against a 'cam,h,.(see Fig. 9 for `detail,) rbeing pressed thereon by a spring, h5.

ing mechanism consists in part of'a needle, k,

The stock h slides in ways in a carriage, It, and this carriage is guided by rods h7 entering proper guide-blocks, the rods and the carriage being attached to the sliding bar. It,

This bar has on its end a friction-roller, whichV is forced into contact with-the cam hf* by a spring, hg. Y

Now, the object-of this arrangement is as follows, viz That the folder may move in'any necessarydirectioii sidewise, endwvise, Aor diagonally,'it' being moved endwise through the agency ofthe lever, sidewise by the basil/t3, and diagonally by a motion of both at the same time;'andthe folder3 ismounted in 'substantially the same manner,'and 'both folders may, by a proper shape-andj adjustment of cams, have imparted to them any requiredlength of motion in any desired direction at such time as shall be necessary to cooperate with lother motions 'ot' thev machine. This folder l has attached to itsupper surface a rod, h1, Which-slides at times over awedge, h,the operation of the two being to lift the folder as it advances toward the mouthpiece.

Another blade, 3, is mounted on a stock, j, which can slide to and fro in a carriage, jl.- The lcarriage is guided by rods, and moved by a sliding rod, jl, provided With'a frictionroller restingV against a cam, js, (see Fig. l() for detail.) A spring similar to h9 causes the roller to press againstithe cam. The stockV -has pivoted to it a lever, j, whichis centered upon a` projection fromthe sliding 'rod'j,:and'

the end of this lever abuts .againsta cam, 3'5, being pressed against the cam by a spring arranged and acting like h5. This folder has also attached to it a rod, j, which, in connection with a stationary wedge, y, causes the folder to lift at a certain part of its advancing motion. By means of the cams and attachments this folder is caused to move in directions and through distances as required in a similar manner to folder l. The folder l has a projection from its upper surface at y, the folder 2 at Au, and the'fol'der 3 at z. These projections are surfaces at right angles, or nearly so, with the surfaces of the folders.

Y VThe vdischarging apparatus has two functions, the one in conjunction with the folding apparatus to advance the folded tape to be tsewed, `the other to carry the sewed and folded tape out of the machine. It consists essentially of two surfaces,A Z Z1, which at times gripe the folded tape between them. Both of these surfaces are slotted along their centers so as to permit of the action of a spring, m, and a stationary surface, n. The surface nis fastened to the bed-plate; the surface -Zl surrounds it, and is free to slide in ways, or in a slot in the bed-plate. The spring m enters the slot in Z, and rests upon the surface n so that it can gripe tape against a. The surface Zl has projecting from it two pins, (see Fig. 1,) and the surface Z is provided with another pin which enters between the two former ones. The surface Z is attached by a pivot to an arm, Z2, pivoted at Z to a standard, Z4, which is free to oscillate. The end of the arm Zz has secured to it a pin, 1,5. This pin rests against a face-cam, ll, and the end of the lever rests upon acam, Z". A spring, l, causes both the pin and the end of the arm to bear The cam Z6` f notaio-mi se and depress;y thenpper surface j.,

the tape over the diagonal edge of 3, which is against their respective cams.

the'carn ZT acts to move both surfaces in the line of discharge, (see Figs. 14 and 20.)

The action of the whole apparatus is as follows: When the two surfaces-are in contact they grasp the folded tape; When Z moves away from the folding apparatus it, by means ofthe pins, carries Zl with it, and bot-h grasping the folded tape carry it past the needle and out of the machine. Then Z rises, and the tape isheld -at rest by the spring compressing it aga-inst the stationary surface n. NVhen Z moves toward the folding apparatus it carries Zl with it, and then descends, so as to grasp tape again between itselfand Z. l and Z1 act like pincher-jaws to seize and release and carry along the article which has been seized. m and r)tact -to hold -an article at rest while the pincher-jaws are separated and moving to take a new hold. It is necessary, therefore, that the 4grasp, of the spring should be less forcible than that 'of the pincher-jaws. The motions ot' the disghargingapparatusnnust, by proper shape and adjustment of cams, be of suitable length and so timed as to work. in proper concert with the folders, and draw ,i he tape along when the needle is out of it. 1n working withthe' machine tape is to be wound upon the reel, led -down the tube andthe mouth-piece, and may then be carried .under folder 2, between it and folder 3, under 3 and between it, and l, then under folder l, and so out under the'neeflle and under the spring m. Fig.' 3 represents the parts in this.position. The iirst motion of the machine will thenfturn the mouth-piece and cant it so as to draw the tape over the folding edge of the folder 2. Folder l will now back diagonally out from under the folded tape in such a curve that h1", in so doing, does not touch h1,and will then advance again. In so doing its rod will ride over the wedge, which will lift the folder so that it rides over the tape and folds it down ony top of folder 2, finally biting the tape firmly between its advancing edge and the projection z on folder 3. The mouth-piece now turns again, the roller d hindmost in Fig.2 rides on top of the lefthand forward protuberance in di, (see s, Fig. 7,) and the mouth-piece is so canted as to draw the tape from the folding edge of 1,4

directly toward its stock. Folder 3 now retreats ont from under the tap-e and advancesv In so doing it rises by its rod, riding over wedge jl. As it comes over the tape it folds it down on top of folder 1. Folder 2 now retreats, and rises by rits rod rising over its wedge, and when it has done so, folders l and 3, clasping the folded tape, (such clasping being aided by the edge of 3 striking tape against z,) advance together in direction of motion of the discharging apparatus. The movable jaws of the apparatus move at the same time, and in the same direction, carrying the folded tape under the needle and out of the machine. The tube now turns again, the rolle-r da, foremost in Fig. 3, rides on top ofthe protuberance t (see. Fig. 7) on dl, and the mouth-piece cants rearward so as to draw again.

nearest the front of the machine. Folder 2, being now high enough to override the tape, then advances over the tape, folds it down upon 3, and nips it against the projection. While this is doing the needle has descended and, Vaided by the hook, taken a stitch in the folds to hold them in place, and the upperdischarging-jaw has lifted, relaxed its grasp 0n the tape, moved in a direction contrary to that ofdischarge, carrying the lower jaw with it, and has descended again so as to take a fresh hohl of the folded tape. While both the jaws were moving in the reverse direct-ion, the folded tape has been held at rest by the spring m. Folder' l now retreats again, the mouthpiece again cants so as to draw tape over the edge of folder 2, folder l advancesthe mouthpiece, cants folder 3, retreats and advances, and so on, as before described, making' fold after fold. The needle may retreat out ofthe tape at any convenient time wheuthe tape is not in motion, and the cams must be so shaped as to give motions at times and in the directions as described,`and it will be observed that the great principle of the folding apparatus is that each blade shallfold over the edge and surface of another, and that each folder shall retreat when lowest, and in its advance take the high- .est place.

rEhe springiness of the folders is important in this respect, not only as permitting the folders to take the proper positions, but asenabling them always tol press firmly upon the tape; but they might receive all their motions from cams. Gams shaped substantially as shown in the drawings will niahe a trini` naine' like that shown in Fig. 2l, and other shapes of cains will. maire other varieties of folds, Fig. Qlibeing a representation of the upper and under sides of vthe trinnning, Fig. 22 being a representation of another variety of trinnning and Figs. 23 and 2i representing triinining that can be made by certailralterations not affecting the principles of the inachine, and these varieties nia-y be added to by changing the nuinber, relative position, and movement of folders. Certain folds may be`n1ade without the cant-ing motion ofthe mouthpiece, and by a mere revolution of the" tube, and tolerable Werl; may be donc without the projections froin the surface of the folders; but for lthe best wjora we prefer to make the machine in all respects as dcscribed, and to take but one stitch in the folded goods for every lnotion -of the dislcharger,ln1t more stitches may be taken 'it' desired. ur `plan is i'o Yrcseiv the folded trimming after it has left' the machine with as great a number of stitches to the inch as may bc desired, and then to rip or ravel out the seam put in by the machine, but this seam may, byI a proper arrangement ot' parts, be made close and tight enough to do away with the need of subsequent sewing.
