. SPECIFICATION forming part of Letters Patent No. 562,109, dated June 16, 1896.

Application filed October 21, 1895. Serial No` 566,287. (N model.)

parts hereinafter described, and particularly pointed out in the claims. The machine made the subject hereof embraces the usual parallel horizontal feed-disks,

horizontal reciprocating needle and oscillating looper, all of which in the present machine have theircustomary and usual movements.

The present invention resides in certain improvements in the main supporting-frame of the machine and in the operative mechanism -intermediate the feed-disks, needle and looper, and the main driving-shaft.

The object of the invention is to simplify the operative mechanisms, reduce them in number, bring them into more effective operative relations, render them more positive in action and more durable in use, and adapt them for convenient adjustment, and to produce a machine capable of ready manufacture and ease of operation.

The invention will be readily understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Y Figure 1 is a vertical longitudinal section through a machine constructed in accordance with and embodying the invention, the section being on the dotted line l l of Fig 3. Fig. 2 is a vertical transverse section of a portion of saine on the ydotted line 2 2 of Fig. 3 and illustrates a part of the front of the machine, a portion of the latter being in section in line with the screw by which the feed mechanism may be adj Listed. Fig. 3 is a top View, partly in section, of same, the covering-cap for the frame of the machine being omitted. Fig. 4 is a detached top View of a reciprocating bar which carries the looper-bar. Fig. 5 is a detached vertical section of a portion of the niachine on the dotted line 5 5 of Fig. 3. Fig. (5 is a detached elevation of one of the cams forming a part of the operative mechanism of the machine. Fig. 'Z is a transverse horizontal section of the machine on the dotted line 7 7 of Fig. l. Fig. S is a perspective view of the cam shown in side elevation in Fig. (i. Fig. 9 is a vertical section of same on the dotted line9l 9 of Fig. 6. Fig. 10 is a perspective View of a portion of the interior mechanism ofthe machine and is hereinafter specifically referred to, and Fig.11 is a perspective view of an actuating-arm which in use is intermediate the cam illustrated in Fig. 8 and the looper bar and imparts motion from the former to the latter.

In the drawings, A designates the main framelof the machine; B O, the usual horizontal substantially parallel feed-disks; D, the needle, and E the looper. The disks are of the usual well-known form and construction, the disk B being mounted upon the upper end of the usual revoluble vertical shaft F, upon whose lower end the feed-actuating mechanism is applied, as hereinafter described. The feed-disk O is mounted upon the lower inwardly-turned end G of the reciprocating bar l-I, the main body of which ascends above the disk C and thence turns directly rearward through guides' l, formed in the frame A of the machine. The bar H is held within the guides Iby means of the screws J J, entering the frame of the 1nachine,as illustrated in Fig. 3, and having their heads projectin g over the upper surface of said bar H. In the base of the guide I is provided the screw K, upon which the bar H rests and the position of which regulates the position of the bar H and consequently the relation of the disk O to the disk B. By adjusting the screw K upward or downward the disk O may be adjusted vertically in accordance with the character of the goods under treatment and the desire of the operative. Upon the cap L of the frame A being removed the screws J become exposed and upon their 'withdrawal the bar H may be removed and the screw K adjusted at will. The screws J are adapted to the various possible adjustments of the bar H and will be screwed downward more or less in accordance with the position of the IOO being depressed by the foot of the operative; the lower end of the lever N will be thrown rearward and this will have the effect of causp ing the upper end of the leverN to move the bar H and feed-disk C forward, thus separating the disks B C and `permitting the insertion of the goods between them. Upon the foot of the operative bein g removed from the usual treadle the spring P will restore the lever N to its normal position, thereby caus-` ing the bar Il and disk C to returnA rearward to their former position, the disk C pressing the goods against the edge of the disk B, as usual.

The upper end of the lever N is slotted, as

illustrated in Fig. l, and passes upon the pin Q, secured to the bar Il, and hence the lever N is enabled to actuate the bar Hin the manner above described. The spring P at its rear end is connected with the lever N, while at its front end said spring is connected with the screw R, which passes through the front of the machine and is provided with the adjusting-nut S. The screw R is not permitted to revolve, but is adapted to have a direct longitudinal movement under the action of the nut S, the purpose of which is to enable the operative to conveniently regulate the tension of the spring P upon the lever N, bar II, and disk C.

l t will be observed that the nut S is in convenient position to be readily grasped by the operative and that the tension on the disk C may be quickly and conveniently adjusted. The opposite sides of the screw R are flattened, as indicated in Fig. '7, in order to prevent thc screw from revolving axially within the aperture through which it passes, the

walls of the aperture closely iitting against` the Iiattened sides of the screw.

The bar H4 is oi a form, as illustrated in Figs. 1 and 3, which leaves the lower part of the machine entirely open for the reception of the goods to be introduced between the feed-disks B C, and this is a feature of great importance, particularly when heavy seal goods are to be treated.

The needle-bar is lettered T and moves in guides formed in the frame of the machine. Upon the front end of the bar T is provided a usual head V for clamping the needle D, and within the frame of the machine there is secured upon the bar T the bifurcated frame lV, whose opposite members pass downward upon the opposite sides of the grooved cam X, rigidly mounted upon the driving-shaft Y. The needle-bar T, frame NV, and cam X are not in themselves new, and are shown in "Letters Patent No. 275,506, granted to W'. Ludeke April l0, 1888. The needle-bar T is given a due reciprocating movement through the frame Ytand cam X from the driving-shaft Y.

The looper-rod proper is lettered c, and lit carries the usual looper E and imparts to it a longitudinal reciprocating motion, a transverse oscillatory motion, and an up-and-down motion, all of which motions are customary and usual in this class of machines. The looper-bar a is mounted in the sleeves l; l) of the bar c, (shown in detail in Fig. 4,) which is at its rear end pivotally connected with the rod d by means Vof a screw e entering the sleeve j', the latter being integral with the said bar c. The bar d is mounted in guidingapertures in the frame of the machine and has a due longitudinal reciprocating motion therein, and upon the said bar Z is mounted a frame g, (shown in detail in Fig. 10,) the upper end of which forms a yoke h, encom passing the `grooved cam t', secured upon the drivingshaft Y.

The action oi' the cam t' during the operation of the machine is to impart to the rod d a reciprocating motion, the said cam coming into contact with the opposite sides of the yoke h. One member of the frame g forms a down'wardly-extending rod j, carrying the cam m, which, during the reciprocating mo* tion of the frame g and rod d, serves to actuate the feed mechanism, as hereinbeiore dcscribed. The cam 'L' and frame g, acting through the rod d, impart to the frame c a rcciprocating motion, and since said frame c carries the looper-bar a the latter will, during the operation of the machine, have imparted to it a reciprocating motion. lt is necessary, however, that, in addition tothe reciprocating motion, the bar a shall have an axial motion and an up-and-down motion, and hence the bar c is actuated from the cam m through the arm o to have its upanddown motion, and the bar a is actuated from the cam j) through the curved arm q to have its axial motion, the latter being essential to cause the looper to have an oscillatory motion across the path of the needle. The arm q is illustrated in Fig. ll and has upon one end the sleeve Ir, which is secured upon the bar a, while at the other end of said arm q is provided the roller s, which enters the cam-groove p, as illustrated in Figs. 2 and S. During the revolution of the driving-shaft Y the cam p 'will cause the lower end of the arm (l to have an oscillating movement, and since said arm is secured by a screw or other means to the bar a the latter will have imparted to it au axial movement within the sleeves l) b, conneeted with the bar c. The revolving motion of the driving-shaft Y, acting through the cam n and arm o, will, during the operation ol' the machine, cause the barc to have an 11p-anch down movement, and since the bar c is coI1- lOl) IIO

nected with the bar a the latter and the looper E will have 'imparted to them the proper upand-down motion. In view of the fact that the bar'c is pivotally connected with the rod d the said bar may have the up-and-down motion just referred to without interfering with its reciprocating motion. The cams a p are formed in the wheel t, which is eccentrically secured upon the driving-shaft Y.

Upon the lower end of the vertical feedshaft F is rigidly secured, within the frame of the machine, the disk w, which has an upwardly-extending annular rim which supports the two pawls A', the latter at their outer ends being thickened and grooved to fit upon the upper edges of said rim cc, as indicated more clearly in Figs. l and 7. The shaft F has mounted upon its lower end, above the disk w, the arm B',which extends rearwardly, and is provided with a stud C' and spring` D', the stud being in Contact with the cam m, here'inbefore referred to, and being caused to follow' the outline of said cam by means of the springD'.

The arm B carries the pins E', to which are'y connected the'springs F', which pass thence to the pawlsV A', as indicated in Fig. 7, and upon said armB', adjacent to the base of the shaft F, are provided the ratchet-teeth G', which are engaged by the points of the pawls A'. During the reciprocating motion of the rod d and frame `g the cam m, carried by said frame, moves against the stud C' on the arm B' and causes the latter to have an oscillatory motion, whereby the ratchet-teeth G' are caused to act upon the pawls A and through said pawls to rotate by intermittent motions the disk w and shaft F.k 'lhedisk tu, having the rim @the pawls A', and ratchet-teeth G', engaging said pawls, are not of themselves new at this time, they having been shown and described in the aforesaid Letters Patent of the United States, No. 275,506.

The front end of the arm B' extends forward of the shaft F and operates in connection with the stop H' to limit the movement of the arm B' and disk w. The stop H' consists of the threaded rod mounted in a threaded aperture formed .in the frame of themachine, as illustrated more clearly in Fig. 7,

and said stop II' is provided with a head I',

by which it may be adjusted to suit prevailing conditions. B y moving the stop H' outward the bar B' is permitted to have a larger throw, and consequently the disk w will under each movement of the cam m have a more extended axial motion, and when the stop H' is adjusted inward. the extent of movement of the arm B' is restricted and the disk Iw will have a shorter intermittent revolving motion. The arm B', as shown in Fig. 7 is moved in one direction by the cani 'm and in the opposite direction by the spring D'. lVithin the machine I have provided the guide-rod J' for the frame g, and upon the end of this rod J' is formed the flange K', which Serves as a stop at the end of the natural movement of the frame g. The guide-rod J' serves not only to guide the frame g, but to brace the lower portion of same and keep the cam m with firmness against the stud C' on the arm B'. In the absence of the rod J' the force of the spring D' might tend to prevent regularity of action in the cam Fm.

The frame A may be of any suitable or usual construction, but in the present instance I have provided certain advantageous features inthe frame A shown. Great difficulty has been experienced in preventing the oil used in the machine from getting upon the fur garments being treated, and to overcome this objection the bar I-I has been carried upward and rearward out of the way and the bottoni of the frame A has been closed, as indicated by the solid bottom L' in Fig. l.

The rear portion of the frame A is provided with a door M', by which the interior mechanism, with the exception of the feed mechanism, may be reached, and in order that the feed devices may be readily inspected the upper front portion of the frame A isprovided with the covering-plate or horizontal door N', the latter being directly over the feed-disk w and being secured in a hinged manner by means of the lugs O', engaging pins P', the latter being upon the frame of the machine and the former upon the lid or door N'. The central portion of the cover N' is cut away to iit around the bracket Q' for the lower end of the shaft F, and the lugs O' are at the outer corners of the said lid or cover and pass upon the opposite side edges of the machine,as illustrated :more clearly in Fig. 7.

It will be noticed that upon the elevation of the lid or cover N' the pawls A', springs F', disk w, and stop II' are all exposed and may be readily reached. The presence of the cover N' in the position referred to possesses the further advantage that the machine does not have to be turned upside down, as heretofore, when the operative desires to get at the feed mechanism.

In the arrangement of the parts of the machine an aperture is formed in the bottom L' of the machine, and the screw securing the disk w to the shaft F is inserted upward through this aperture, which is thereafter closed by the screw-'plug W', as illustrated in Fig. l.

As above described, the motions imparted to the needle, looper, and feed-disks'are the usual and customary motions for this class of machines.

The machine constructed in accordance with the present invention 'is of great simplicity, durability, and efficiency and has an ease and smoothness of movement and posi- IOO IIO

tiveness of action not before attained, sofar ted from the main driving-shaft Y through the medium of the cam i, frame g, cam Vm, arm B', disk yw, and pawls A'. The needleD has aplain rccip rocating motion, as usual, andreceives the same from the `main driving-shaft Y through the cam X, frame IV, andneedlebar T. The looper E receives its longitudinal reciprocating motion from the main drivingeshaft Y through the `cam i, frame r, bar c, and looper-rod a, and said looper has imparted to it its usual up-and-down motions or its motion from the position shown in Ifig.' l upward from the disk B, then downward when over the 'disk C, then upward when over and about to leave said disk C, and then down.

ward "when over the diskB to the pesition shown in Fig. l, through the instrumentality of the cam n, arm 0, frame c, and looper-rod a, the latter and the armc at `such time having a longitudinal oscillating or recking motion on the screw c. The loo'per E receives its usnal oscillatory motion across the path of the needle D by 'means of the cam p, `arm q, and 4ro'd a.
