FERRULE-SHAPING MACHINE.

Application filed November 3, 1920. Serial No. 421,42'9.

T (67 Z to 710m it may concern Be it known that I, WILLIAM E. YOUNG,

a citizen of the United States, residing at Baltimore, in the State of Maryland, have inventeda certain new and useful Improvement in Ferrule- Shaping Machines, of which the following isa specification.

My present invention relates particularly to a ferrule-shaping machine, adapted to be operated by power.

An object of my invention is the application of mechanical power in the giving of a'desired configuration to closed metallic bands, or the like, and especially the shaping ofbands or ferrules such as are commonly comprised in the heads of paint brushes used by house painters.

Brushes of the type referred to are usually provided with a handle of wood or the like, at one end of which is secured a body of bristles, or their equivalent, and the band or ferrule referred to, may be comprised of a section of drawn metal, or may be formed by cutting transversely a hollow cylindrical body or by uniting the ends of a suitable piece of sheet metal.

The ferrule referred to, when used on a paint brush, is typically so employed as to secure, hide, and protect the joint between the handle and the fibres, or the like, that constitute the head of the brush. 7

Before being put in place on the head of the brush, such a band is ordinarily in need of a final shaping, which shaping must of course secure a fairly accurate correspondence with the transverse sectional configuration of the brush upon which the hand is to be used. As brush holders are manufactured not only in large quantities but inn 4 great variety of sizes and styles, the foregoing implies the need of a capacity for alterations, by adjustment or substitution,

in those elementsof the band-shaping ma chine which determine the final size and configuration of the band; and the objects of my invention include a facilitating of such adjustments or substitutions; and the objects thereof also include the providing of a machine, capable of a wide variety of uses in addition to those mentioned, which shall be compact, rugged, rapid, safe, attractive in appearance, and provided with a means for the application of power and the immediate and easy control ofv an operative who, the desired adjustments or substitutions having been made, need only place the band to be shaped upon the work engaging elements hereinafter described, and then move a lever to secure application of power from an outside source thereto.

Further objects of my invention will appear from the detailed description set forth hereinaftenand, while my invention is capable of embodiment in many different forms, for the purpose of illustration 1 have shown only certain forms of my invention in the accompanying drawings, in which:

Fig. 1 is a front elevation of a preferred embodiment of my invention.

Fig. 2 is an end elevation as viewed from the left of Fig. 1, but not including the casing 30, nor the drive pulleys 31, 31', shown at the right of Fig. 1,

Fig. 3 is a vertical longitudinal section corresponding to Fig. 1, and, for the most part, in the plane of the main drive shaft, that is to say, on line 3-3 of Fig. 2.

Figs. 4 and 5 are vertical transverse sections, on lines l- 1, and 5-5 respectively of Fig. 1, looking in the direction of the arrows.

6 is a plan view. I

In the form of my invention herein shown, there is a hollow main casting, frame, or housing 24:, which may restupon any suitable foundation, and which in turn preferably sup-ports both the work-engaging parts 14, 1 1 and the actuating mechanism therefor.

Although any suitable source of power may be used, I have herein shown a speedreducing drive mechanism comprising

tightanddoose pulleys

31 and 31, the outermost pulley being preferably secured, by means such as collar 33, against lateral movement on the shaft 18. The shaft 18, shown as carrying only a gear 19, preferably keyed thereto, may be supported in any suitable way, as by (1) the double bracket 29 (carrying also the main shaft 32), and (2) a suitable ring or rings for securing one or both ends in casing 24.

The work-engaging parts or posts 14, 1% maybe of any desired external or trans verse configuration, and one or both of them may be removably and adjustably secured, to facilitate either a change in the form and curvature given to the ends of bands worked upon. or a change in the distance therebetween-the latter change being made whenever, the requirements as to thickness and type of brush remaining unaltered, there are to be handled successive batches of bands or ferrules differing only as to the width or longer transverse diameter of the brush heads in which or upon which they are to be used.

While it will be obvious that the desired shaping action might be attained by a suitable movement on the part of either or both of the work-engaging posts referred to, I have shown in the drawingsa fixed post l l as secured by machine screws to the main frame 24:,appropriate means being, however, provided for guidance and a justment as well as reciprocation of the corresponding post 14.

It being desirable that the work-engaging posts 14, 14 shall belconveniently positioned for the placing and removal of successive bands or ferrules to be shaped or stretched thereby, I have preferred to make provi sion such as an undercut channel in the top of the main casting 24:. In this channel I have shown a reciprocating element which, for convenience, I hereinafter designate as carriage 21, and which is shorter than the mentioned channel in which it moves. It may conveniently be given the desired alineinent andsecurity in said channel by means such as the adjustable and removable spacing plate or gib 12. Said gib in turn may be secured in any suitable manner, as by pins 26, each preferably provided with a lock nut or nuts 39, the reciprocating carriage 21being free to slide relatively to the said plate or gib 12. v

To the rearward end of the carriage 21 I prefer to secure, by any convenient means, such as bolts orscrews 40, a threaded bearing element 13, to receive a corresponding long adjusting screw 8, to one end of which screw I may secure suitable actuating means such as the crank 28, shown as provided with handle 15, the other end of the shaft of screw 8 being preferably provided with a circumferential groove to secure thereto, by means such as pins 41, a slidable element 11 carrying the work-engaging post 1&, which may be removably secured thereto for convenient substitution, by means such as.

screws 42.

If desired, a set screw 43 may be provided in the threaded bearing block 13, to secure in any adjusted position the mentioned screw 8, the preferred construction being such that whenever, to effect the expanding or shaping of a band placed over the posts 14, 14, the carriage 21 shall be reciprocated, the crank28 and all associated parts must reciprocate therewith.

To effect the desired reciprocation of the carriage 21, any convenient means may be employed, and in the present embodiment of the invention I have imparted the desired IGCiPIOCiLtiIlg motion by means of an arm 25, shown as depending from the plate l3, which plate maybe secured, by means such as screws 44, to the bottom of the carriage 21. The arm 25 preferably carries means such as pin 17, which may be provided with rollers 22, and may be secured by a set screw 4l5, for effecting contact with cam grooves in discs 1., shown as rigidly mounted on the main shaft 32, which is adapted for occasional or intermittent rotation.

As shown, shaft 32 may have one of its bearings in the bracket 29, screwed to the main frame'or housing 24, and its other end may advantageously be provided with a friction collar 10, preferably keyed thereto and shown as capable of rotation in a split bearing, provided with adjustable means for a braking effect, such a bearing being shown at 3, secured at 38, the lubrication of the shaft being, however, provided by means such as Winlrley oiler 35, with lubricating sleeve 5, the function of the described brake organization being; a prompt retardation in the main shaft 32, and of the described reciprocating means driven therefrom, when ever the power shall be thrown off from the said shaft, as may be done by means hereinafter described.

On the main shaft 32 there are mounted any suitable means for transmission of power thereto from the gear 19, heretofore mentioned. It would obviously be possible to transmit suitable motion to the shaft 32 in a continuous manner, thereby occasioning a rythmical reciprocation of the post 1% relative as to the post 14, the operative being then expected to utilize, for the placing and removal ofthe bands to be stretched, those intervals when the posts are relatively close together. I, however, prefer to provide means such as a clutch and stop mechanism for transmitting motion to the main shaft 32, and thereby to the post it, the said clutch being preferably under manual control through means such as lever 2, herein shown as pivoted to the main frame 24, and normally held in its rearward or rest position by means such as the spring 16.

In the construction shown, the forward movement of the lever 2, elevating the hook 426, and causing the engagement thereof with a pin or stud 4L7 on the cam-faced lever 48, pivoted at 19, and depressed by the spring 18, permits the curved or practically circular leaf spring 50 to force the pin 51 into the path of the heads of the bolts 20, which heads project from the face of idlly revolving effect clutch gear 27, constantly driven by the gear 19 (and preferably protected by a casing 30) to thereby cause the clutch element 52 (carryin the tripper to revolve therewith and to rotate the main shaft upon which it is mounted-all for the purpose and with the efiect above described.

It is in order to limit the effect of the movement of the lever 2 to a single reciprocation of the post lt that means such as the mentioned tripper 53 are provided, and this tripper is so placed on the clutch element 52 that, even if the operative happened to fail promptly to release or return the lever 2, the first revolution of the clutch element 52 willautomatically, by contact with the said tripper with a face 54: of the hook 46, cause a disengagement of the lever from the stud on the cam-faced lever 4L8,the depression of which, under the action of the spring 18, will, by the engagement of the cam face with the notch in the pin 51, cause a retraction of said pin and thereby a disengagement of the clutch, all parts being incidentally returned to their original position.

From the foregoing it Will be apparent that, upon the placing of a band over the posts 14 and 14, and the pulling of the lever 2, there is caused a single reciprocation of one of the posts, and the parts are thereafter brought promptly to rest in a position suitable to a repetition of the described operation.

What I claim is:

1. In a band shaping machine, a fixed post and a movable post mounted on a carriage, a power shaft and a second shaft, means connected to the latter and the carriage for reciprocating it, a clutch for connecting the shafts, and automatic means for disengaging the clutch comprising a tripper rotating with the clutch.
