I'IAT-BODY-CLIPPING MACHINE.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application led February 3, 1910. Serial N o. 541,771.

l To all whom it may concern:

Danbury, county of Fairfield, State of Connecticut, have invented "an Improvement in Hat-Body-Clipping Machines, of which the following is a specification.

This invention relates to certain improvements in machines for clipping the long hairs of fur hat bodies to a predetermined length.

In hat body clipping machines, as heretofore constructed, it has been common to use a single metal cone of sutlicient size to hold the body up to the cutting line, that is, the line at which a series of cutters carried by a cli aping cylinder pass a bed knife. The dit culty in using this type of machines has been that it was almost impossible to keep the body uniformly taut at the cutting line; As the body is carried merely by its own weight it does not get sufficient grip upon the cone so that it can be held taut by the hands of the operator without slipping on the cone and being brought to a standstill, or else if the operator relieves his pressure on the body, of its being drawn into the cutters and seriously injured and frequently ruined.

It is one of the objects of the invention to produce a body clipping machine in which the driving shaft shall be journaled near the floor and the swinging frame shall be so constructed and pivoted as to reduce vibration to the minimum and give great steadiness and stability to the machine.

A further object of the invention is to provide means for imparting longitudinal reciprocatory movement to the clipping cylinder whereby a shearing cut is produced and the cutters remain sharp for a much longer period than heretofere as the wearing point is constantly changing.

A further object of the invention is to provide novel means for picking up and raising the nap just before the cutting line.

A further ob ject of the invention is to pro vide means for protecting the hands of the operator so that they will be in no danger of being drawn into the cutters.

A further obj ect'of the invention is to provide adjustments for the several parts which shall be positive, easy to operate and will secure the most perfect regularity and uniformity of results.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements and combinations which will be hereinafter described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings forming a part of this specification, in which like characters of reference indicate the same parts, Figure l is a front elevation of the machine partly broken away; Fig. 2 a plan View partly broken away; Fig. 3 a side elevation s as seen from the right in Fig. l; Fig. 4 a side elevation as seen from the left in Fig. l; Fig. 5 a sectional view on an enlarged scale on the line 5-5 in Fig. l looking in the direction of the arrows; Fi 6 a detail plan view on an enlarged sca e partly broken away, illustrating the mechanism for lreciprocating the clipping cylinder; Fig. 7 a detail front elevation corresponding with Fig. l illustrating the mechanism for adjusting the lower feed roller; Fig. 8 a detail elevation partly in vertical section as seen from the right in Fig. 7 and Fig. 9 is a detail elevation of the upper feed roller standard and the lower feed roller bearing partly in vertical section. j

In Figs. l, 2, 4 and 5, the parts are shown in the operative position, and in Fig. 3 in their normal position, the frame which carries the bed knife and clipping cylinder being swung out of operative position. The framework comprises side-pieces 2O which are braced by cross-pieces 2l and support a bed 22. Iower is applied to drive the machine by means of a belt (not shown) passing over fast and loose pulleys 23 and 24 on a driving shaft 25 journaled in bearings 2G which are placed low down in extensions 27 of the side-pieces. These extensions are provided to give a wide base to the framework, which in connection with the fact that the driving shaft is journaled low down and near the lloor gives great stability to the 'framework and does away with much of [he vibration which has been such a serious objection in machines of this class as heretofore constructed.

Q8 (see Fig. 5) denotes a hat body that is being operated upon.

It is of course well understood that machines of this character are not wholly automatic in operation, but thatthe feeding of the bodies to the cutting line is materially assisted by the hands of the operator. 1n the present machine, the bodies are fed over a table or shoe indicated by 29, and between upper and lower conical feed rollers indicated by 30 and 31 which are placed one above the other and both directly under the table or shoe, the bearings for the upper feed roller being stationary and the bearf ings for the lower feed roller being movable, as will be more fully described. The table is carried by an arm 32 extending from a plate 33 which is secured to the bed in such a manner as to permit adjustment of the table relative-ly to the upper feed roller whose posit-ion is fixed as will be more fully explained. The plate is held in place by means of a cap screw 34.

35 denotes tilting screws which pass through plate 33 andbear upon the bed, four of these screws being ordinarily used surrounding the cap screw. rlhe cap screw being loosened it is obvious that plate 33 may receive a tilting adjustment by means of screws 35 to place the table at any re.- quired position relatively to the upper feed roller. Having placed the table at the required adjustment, the plate and table are rigidly locked in place by turning down the cap screw and the tilting screws are locked in place by means of set nuts 36. The feed rollers which are preferably made of wood are carried by upper and lower feed roller shafts indicated respectively by 37 and 38. Upper feed roller shaft 37 is journaled in bearings 39 upon a bracket 40 carried by a standard 41 which is rigidly bolted to the bed. Upper shaft 37 carries a belt pulley 42 and is driven by means of a crossed belt 43, preferably round, which passes over a pulley 44 on the driving shaft. rIhe lower feed roller is driven from shaft 37 by means of corresponding bevel pinions 45 on the two shafts. The lower shaft is journaled in bearings 46 carried by an arm 47 which is pivoted on a stud bolt 48 in bracket 40. This stud bo-lt passes through an elongated hole 49 in a hub 120 on the bracket and is clamped to the hub by means of a nut 50. The angle of the feed rollers to each other is adjusted in order to produce contact at either end or along their entire length as may be required by means of an adjusting screw 5l which is held against longitudinal movement by a yoke 52 on bracket 40 and is tapped into stud bolt 48. By loosening nut 50 and rotating the adjusting screw it` will be obvious that arm 47 and with it the lower feed roller shaft and feed roller may be adjusted as above described (see Figs. 7 and 8). The lower feed roller normally drops away from the upper feed roller by gravity, leaving ample space between the-m through l and practically eliminates vibration.

which a hat body may be passed'. This feed roller is held in its operative position in use by means of a link 53, one end of which is pivoted to a hub 54 on the inner bearing 46, the other end being pivoted to a vlever fulcrumed under the bed as at 66 and connected by means of a rod 67 to a treadle itself pivoted to ears 56 extending upward from one of the lower cross-pieces 21 of the framework. Pressure upon the treadle raises arm 47 and swings the lower feed roller into position to grip a hat body between the two rollers. The insta-nt the operation, presently tov be described, is finished the operator removes his foot from the treadle and the lower feed roller drops out of operative position releasing the hat body and permitting it to be removed from the machine.

The clipping mechnism is carried by an inverted L-shaped swinging frame 57 which is pivoted on studs 117 in ears 118 secured to the bed. The swinging frame comprises two side-pieces 58 which are connected together by one or more cross-pieces 59. The

object in making the side-pieces L-shaped is to provide an approximately horizontal portion to carry the clipping mechanism and also to enable the frame to be pivoted to the bed which is much below the clipping mechanism. This in connection with the placing of the driving shaft near the floor gives great stability and steadiness to the machine 60 denotes the cutters or clipping knives which are set spirally in a clipping cylinder 61 carried by a shaft 62 which is journaled in bearing plates 63 having cap plates 64 and adjustably secured to the swinging frame. Each bearing plate 63 is provided with a rib 68 which engages a corresponding groove in the underside of a side-piece of the swinging frame. The plates are secured to the sidepieces by means of bolts 69 which pass through slots 70 in the plates and engage the side-pieces. Lateral adjustment of the clipping cylinder on the frame is effected by means of adjusting screws 71 carried by lugs 72 at the ends of the side-pieces and engaging the bearing plates.

73 denotes a flexible lubricating strip for 'the cutters which is secured to a cross-piece 74 itself secured between the side-pieces of the swinging head.

Cooperating with the clipping cylinder is a bed knife 75 which is rigidly secured to a bed plate 76 carried by a chair 77 which is suspended from and rigidly secured to the side-pieces of the swinging frame. The attachment of the bed plate to the chair is substantially the same as the attachment of the plate 33, which carries the table or shoe, to the bed. Cap screws 78 pass through slots 79 in the bed plate and engage the chair,

rounded washers 80 being preferably placed under the heads of the cap screws.

81 denotes tilting screws in the chair upon which the bed plate rests. Longitudinal adjustment of the bed plate and bed knife is `effected by means of adjusting screws 82 which pass through lugs 83 extending from the chair and engage the bed plate. Having adjusted the bed plate and bed knife longitudinally by means of the adjusting screws and having secured the desired vertical adjustment of said parts by means of the tilting screws, cap screws 7S are turned down upon the washers to lock the bed plate and bed knife securely in place. The tilting screws are locked in place by set nuts 81.

In order to produce a shearing cut in use and furthermore to produce uniform wear upon the cutters and bed knife, a slow longitudinal reeiprocatory movement is imparted to the clipping cylinder. This is effected by means of a worm 85 upon cylinder shaft (32 (see Fig. 0) which engages a worm gear 80 journaled in a casing 87 which incloses the worm gear and worm and in which the cylinder shaft is mounted to rotate. The shaft S8 of the worm gear is provided with a pin 89 placed eccentrically to its axis of rotation. 90 denotes a link one end of which is journaled on the pin, the other end being pivoted to an ear 91 upon one of the bearing plates G3 in which the cylinder shaft is journaled. As the link can obviously have no longitudinal movement it follows that rotation of the worm gear by means of the worm must necessarily impart longitudinal movement tothe shaft and casing.

In order to provide efficient means for insuring that the hands of the operator cannot be drawn into the cutters, a combined finger guard and suction pipe is provided just in front'of the clipping cylinder and in connection with this finger guard and suction pipe a nap raising brush is preferably used. It is found in practice that the brush is useful in raising the nap and while partly effective is not. wholly effective as a finger guard. The combined finger guard and suction pipe is therefore always provided, it being thoroughly effective as a finger guard, as it renders it impossible for the fingers of the operator to get to the cylinder knives and also effective as a nap raising device. In practice the brush also is preferably used, as it raises the long hairs of the body.

92 denotes the combined finger guard and suction pipe which is simply a flattened pipe extending the length of the clipping cylinder and curved to correspond therewith as shown, thus effectually covering the cutters. This combined finger guard and suction pipe is connected with an exhaust fan (not shown) and is secured to an angle plate 93 which in turn is secured to a plate 94.

Plate 94 is adjustably secured to plates G3 by cap screws 95 and tilting screws 9G in the same manner that the bed plate is secured to the chair and plate 33 carrying the table or shoe is secured to the bed. 97 denotes the brush which is made of rather fine stiff bristles and is of a length equal to the length of the longest hat bodies which my machine is adapted to operate upon. It is secured to a plate 9S which in turn is adjustably secured to plates ($3 in the same manner that plate 94 is; that is, by cap screws 99 and tilting screws 100. It will be noted that these adjustments` of the combined finger guard and suction pipe and of the brush provide for adjusting these members relatively to bearing plates (33, and that said members are afterward fixed to the bearing plates and are adjusted with the bearing plates in the manner described. 101 denotes another suction pipe flattened at its inner end and of a width corresponding with the length of the longest hat body. Ihe flattened inner end of this pipe lies back of the clipping cylinder and bed knife and rests upon the bed plate. It removes from the machine all the hairs that are clipped at the cutting line.

The swinging frame and clipping cylinder are normally held out of operative position by means of a spring 102 one end of which is adjustably secured to a bracket 119 rigidly secured to the bed, and the other end to an arm 103 which is rigidly secured to and extends downward from one of the sidepieces of the swinging frame. The swinging frame is drawn forward into operative position by means of a rod 101, one end of which is pivoted to an ear 105 on the under side of the chair, the other end being pivoted to a treadle 10G which is itself pivoted to ears 107 extending upward from one of the lower cross-pieces 21. of the framework. When the operator places his foot upon the treadle, he swings frame 57 and the clipping cylinder forward into operative position. The position to which the swinging frame and clipping cylinder are carried is determined by stop screws 108 in brackets 109 which are rigidly secured to the bed, the side-pieces of the swinging frame when in operative position bearing against the ends of the stop screws. lt will be understood that the adjustment of these stop screws determines the height of the cutting line and enables the operator to clip the hair to any predetermined length.

The clipping cylinder is driven by means of a belt 114 passing over a belt pulley 115 on the driving shaft and a belt pulley 11G on the clipping cylinder' shaft. When the clipping mechanism carried by the swinging frame is in operative position the centers of belt pulleys 115 and 11G and the studs 117 upon' which the frame swings are in direct alinement with each other, thus insuring a tight belt when the clipping cylinder is running and also securing the most perfect stability and steadiness of the entire machine.

110 denotes a guard plate which may or ymay not be used upon the machine which bears upon the hat body in use. The object of this guard plate is to cause the swinging frame and clipping cylinder to rise and fall in use in passing over thickened portions of hatbodies and thereby prevent injury to the bodies and insure a uniform length of the nap without regard to the thickness of the bodies and furthermore by adjusting different portions of the guard plate at a greater or less distance from the bed knife to provide for clipping a nap longest at either brim or tip or longer at the quarter than at either brim or tip. As this guard plate is not a portion of the present invention it will not be described in detail.

The operation of the machine is as follows: The clipping cylinder, bed knife, table, lower feed roller, combined finger guard and suction pipe, and the brush if used, are adjusted to the special requirements of use in the manner already fully described. The operator then places the hat body to be operated upon over the table, under the upper feed roller and over the lower feed roller, as clearly shown in Fig. 5. He then places his foot upon treadle 55 and raises the lower feed roller into position to grip the hat body. In use it is not necessary to stop and start the machine in inserting and removing hat bodies, for the reason that the clipping cylinder and lower feed roller are both normally out of operative position and the hat body may be readily inserted between the upper feed roller and the bed knife or between the upper feed roller and the guard plate if used. As soon as the operator raises the lower feed roller into position to grip the body it will commence to move forward. The operator holds the body taut by pressing it down upon the table to insure that it is drawn forward to the cutting line evenly and smoothly and without wrinkles or folds, the finger guard, as already explained, making it impossible for the operators lingers to get into the cutters. The operator then places his other foot on treadle 106 and moves the swinging frame carrying the bed knife and clipping cylin, der into operative position. As soon as the body has passed entirely around one or more times and has been thoroughly clipped, the operator releases both treadles which permits the lower feed roller to drop down out of operative position by gravity and permits spring 102 to draw the swinging frame carrying the clipping mechanism out of operative position. The clipped body may then be removed and another body inserted, as already described, when the operation of clipping may be proceeded with as before.
