TRIM'MING ATTACHMENT FOR LOOPING-MACHIES.
SPECIFICATION forming part Of Letters Patent NO. 408,575, dated August 6, 1889. Application filed lSeptember 25, 1888. Serial No. 286,370. (No model.)
To all whom it may concern.-
Be it known that I, NORMAN H. BRUCE, a
citizen ofthe United States, residing at,
Waterford, in the county'of Saratoga and State of New York, have invented new and useful Improvements in 'Trimming Attachments for Loopers, of which the following is a specification.
My present invention relates to trimmers and brusher attachments for cylinder turning-off machines of the type shown in the applications filed by me and the patent heretofiore' granted to me, all as hereinafter speci- In my application filed March 1, 1888, Serial blo-265,821, I showa mechanically-driven rotary brush combined with a turning-off machine, together with means for imparting a vibratory or reciprocating movement to said brush in` conjunction with its rotary movement. I also provide devices for adjusting the brush relatively to the points of the turning-off ring. In the Letters Patent granted me October 3,1888, No. 392,005, I
show an automatic vtrimming and brushing attachment for turning-off machines, whereby the impaled fabrics are cut or trimmed and their edges cleansed by automatic devices. In the applicationtiled by'me upon the Sth day of June,1888, Serial No. 27 6,476, I show and describe acutting or trimming and brushing attachment for turning-'off machines, wherein the fabrics are guided to the single cutter and trimmed by means substantially similar 'to those employed in the present application.
Vith these trimming devices are combined a rotary brush and means forgiving vertical and lateral adjustment to said devices and a guide for the edges of the fabrics. With these devices I also combine a reciprocating brush eo-operating with the rotary brush and interposed between the same and the trimmer. I also show means for operating the rotary brush in two different directions relatively to the points of the turning-off machine.
I make no claim, therefore, in the present application to any feature or features shown in the said patent and applications for patents specified above.
It is the purpose of my invention to simplify and improve the construction and operation of the parts constituting the trimming and brushing mechanism, whereby the whole shall be driven by a single belt gearing with the counter-shaft of the attachment and with the brush-shaft. vIt is my purpose,
also, to provide simple'm'anism for giving rotary reciprocation to Jthe cutter from a crank-pin on the brush-shaft, thereby simplifying the machine and diminishing its bulk.
It is a further o bject of my invention to improve and simplify the means whereby horizontal adjustment is given to the cutter and brush jointly and an independent horizontal andvertical adjustment to the brushshaft.
It is one purpose of my invention, also, to so construct and operate the rotary cutter that the trimming shall be eiiected by reciprocating the cutter or trimming disk through a fractional part of an entire revolution, whereby, through simple adjustments, successive portions of the cutting-edge of said disk or trimmer may be used one after another, thereby greatly prolonging the term of effective use, cheapening the cost, and diminishing the labor of operating the machine.
The invention consists in the several novel features of construction and new combinations of parts hereinafter fully described, and then definitely pointed out in the claims.
In the accompanying drawings, Figure l is a side elevation of part of a turning-off cylinder, showing my invention in connection therewith. Fig. 2 is a plan view of the parts show-n in Fig. l. Fig. 3 is a vertical section in the axial line of the countershaft of the trimming and brushing attachment. Fig. 4 is a detail side elevation of the rear end of the arm of the attachment. Fig. 5 is a detail perspective of the adjustable arm carrying the brush-shaft. Fig. 6 is a detail view of the bell-crank lever, by which motion is communicated from the brush-shaft to the trimmer. Fig. 7 is a detail view, enlarged, of t-he iiexible and elastic pitman or connecting-rod between the bell-crank and the shaft ofthe rotary cutter. Fig. 8 is a view of the disk on the cutter-shaft, showing the construction for securing an interchangeable point of connection for the pitman. Fig. 9 is a detail view of the ordinary solidy pitman, reciprocating the cutter-shaft.

The reference-numeral 1 in said drawings denotes the bed-plate of a turning-off machine of ordinary construction, having a cylinder 2, provided with a fringe of points 3, upon which the fabrics are impaled in the usual manner. As this portion of the mechanism shown forms no part of my present invention and is Well known to those skilled in the art, no full illustration thereof has been given, nor is any description essential. I have merely shown, therefore, a fractional part of the turning-oit ring, in order to setforth fully the relation of my invention thereto.
Mounted upon any suitable support 4 conveniently near the turning-o machine is a plate 5, from which rises a standard 6, carrying two parallel arms, which constitute a fork 7. In the ends of these arms is rigidly mounted a cylindrical bearing 8. Rising from the standard'iis a horn or inclined arm 9, the use of which will be explained hereinafter.
Mounted upon the bearing 8 isa short sleeve 10, split upon 011e side, showing projecting lugs 12, through which is tapped a set-screw 13, whereby the sleeve may be caused to grip the bearing 8 more or less closely. Cast with or attached to this sleeve 10 is a tubular bearing 14, having its axis at right angles with the axis of the sleeve 10. \Vithin the tubular bearing 14 is inserted the cylindrical end of an arm 15, upon which all the operative parts composing the attachment are supported. This arm is held at any desired point of longitudinal and axial adjustment by means of a set-screw 16, tapped through the tubular bearing 14. The arm 15 is provided not far from its middle portion with an upwardly-curved yoke or arm 15, and in that part of said arm between the yoke and its cylindrical extremity is formed a slot 17, extending through the arm. Vit-hin this slot and adjustable therein lies a stud or bolt 18, which passes through and gives bearing to the extremity of an arm 19, Fig. 5, having an opening 2O to admit the stud, which receives a nut 21 upon its threaded projecting end, by which the arm may be locked at any point to which it is adjusted.
Upon the free end of the arm 19 is formed a boss 22, which gives bearing to a shaft 23, having a fixed pulley 24. Below the shaftbearing or upon any convenient part of the arm is formed a pin 25, which gives a convenient attachment to a spring 26, the other end of which is connected under tension to the yoke or arm l5 to raise the free end of the arm 19.
Upon the brush-shaft 23 is keyed or otherwise mounted the rotary brush 27, which is of the construction fully shown in my prior application and requires no specific description. This brush is revolved through the pulley 24, which is belted to a pulley 28 on the bearing 8, said pulley being driven by a second pulley 29 rigid therewith. A loose pulley 30 may be provided for the belt when the operation of the machine is to be checked. Tapped through a bearing 31 on the yoke or arm 15 is a set-screw 32, the end of which rests upon the boss 22. By adjusting this set-screw a very exact and delicate vertical adjustment may be easily and instantaneously given to the brush, which is automatically lifted when ever the set-screw is retracted by means of the spring 26.
A protecting cap o1' hood 33 may be hinged to a support 34 on the arm 19.
Upon the forward portion of the arm 15 is attached a fulcrum or bearing 35, upon which is mounted a bell-crank or elbow lever 36, having in one arm a slot 37, which receives a crank-pin 38 on the end of the brush-shaft 23. Upon the end of the other or upright arm of the bell-crank isattached a pitman or connecting-rod 39, connected by its other end to a disk 40, rigidly mounted on a vertical rockshaft 41, which carries the cutter 42. This disk is provided at regular intervals with openings 43, Fig. 8, which receive a wrist-pin 44, and to this pin is connected one end of the pitman 39, the other end of which is connected to the vertical arm of the bell-crank or elbow lever 36.
The vertical rock-shaft 41 is journaled in a bearing 46, having a bracket 47, provided with a circular opening which receives a stud 48, rising at right angles from a cylindrical arln 49. This arm has bearing in a boss 50 on the forward end of the arm 15, and a set-screw 51, tapped through it and bearing upon the said arm, locks it in any position to which it has been adjusted. A second set screw 52 is tapped through the bracket 47 and bears against the vertical stud 48 to permit the bearing of the cutter-shaft to swing horizontally, or substantially so, and to lock said bearing at the proper point.
Through the forward extremity of the arm 15 is tapped a set-screw 53, the end of which is adapted to rest upon the turning-off bedplate. The arm is cleft or split at its end, and a compressing-screw 54 is passed through one end and tapped into the other of the cleft sections to enable the operator to bind the supporting-screw at any point of adjustment.
Cast or otherwise attached to the bearing 46 is a forwardly-projecting bracket'55, upon which are mounted plates 56, one or both of which are elastic. These plates carry guides 57, having edges 58, which are curved to form an open mouth, narrowing to a passage 59, beneath the rearward end of which the cutter reciprocates. A guide-plate 60 is mounted on one of the guides to support the free edges of the impaled fabrics; but as these parts do not materially differ from the invention shown and described in my application filed June 8, 1888, Serial No. 276,476, they require no further description here.
A spring 60, attached to a bracket-hook 61 on the arm 15, is connected to the table or lOO IIO
l. other support l, and serves to hold the arm\ down While the mechanism is in operation.V
Vhen the attachment is not used, or even when it is necessary to have access to the cutter or other adjacent parts, the arm 15 and its connections .may be lifted, turning upon the bearing 3 until the arm rests upon the arm or horn 9, Which furnishes a convenient support therefor.
When ythe cutter becomes ydulled by continued use, the pitman 45 Ais disconnected from the Wrist-pin 44 and the latter is shifted to oneof the adjacent openings 43 in the disk disk 40 as provided with seven equidistant openings 43 5 but it is evident that a greater or less number may be used, as circumstances may require.
Inasmuch as the repeated shifting of the position of the brush-shaft by which the cutter is driven is liable to throw some strain upon the pitman 45, I propose to substitute for therigid pitman shown in Fig. 9 and usually employed heretofore the flexible and elastic pitman shown on an enlarged scale in Fig. 7. It consists of a strong closely-Wound spiral of spring-Wire 62, into the ends of which are introduced the threaded Shanks 63 of the attaching-heads 64. This construction not only permits the pitman to yield readily to strain in any lateral direction, but also allows it to be adjusted in length by turning the shanks 63 in or out. This flexible and elastic pitman also accommodates itself to the disk 40, the Wrist-pin on Which moves in the arc of a circle and thereby imposes some lateral strain on the pitman.
In use the invention is applied to its support in the usual manner, The set-screw 16 is then loosened and t-he arm 15 is adjusted longitudinally and axially until the cutter and guides are brought to the proper point, whereupon the screw is again tightened. Further adjustment of the cutter and guides may be made, if required, by means of the vertical stud 48, on Which the entire cutter-head may be turned, While a further adjustment is possible by the axial movement of the arm 49. When satisfactorilyadjusted and the cutter set at the proper height relatively to the turning-off ring by means of the set-screw 53, the brush is independently adj usted by loosening the nut 2l and setting the stud or bolt 18 at the proper point in the slot 17 of the arm 15.v
The height of the brush is then regulated by means of the set-screw 32, by which, also, the
brush is adjusted from time to time as itv `the cutter. The revolution of the pulley 2S by the belt-connection revolves the brushshaft 23 and its crank-pin, Which, Working in ried under the revolving brush, the latter brushes off the severed parts.
The arm 9, formed or mounted on the bracket 6, serves as a convenient rest or support for the swinging arm of the attachment When'the latter is raised and turned into an inclined position, the tubular bearing 14 turning for this purpose on the shaft S.
What I claim is-' 1. A cutting and brushingattachment for the cylinder of a turning-ff machine, consisting of a supported arm having a brushshaft bearing, a brush carrying shaft arranged in said bearing and having a crankpin, means for revolving the brush-shaft, a cutter-carrying shaft having a Wrist-pin, and devices connecting the Wrist-pin with the crank-pin of the brush-shaft for oscillating the cutter, substantially as described.
