GEORGE E. BRUSH, OF DANBURY, CONNECTICUT.

HAT-POUNGING MACHINE.

PECIFICATION forming part of Letters Patent No. 631,984, dated August 29, 1899. Application filed April 7, 1899- Serial No. 712,169. N m el-l To all whom it may concern:

Be it known that I, GEORGE E. BRUSH, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hat-Pouncing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in hat-pouncing machines, but more particularly has reference to the pouncing-pad, and has for its objects to provide means whereby the pad is prevented from cutting too deeply into the hat, to enable the pad to always extend tangential to the hat-body, and to so secure the sandpaper around the pad that ,it can be readily removed and replaced by a fresh piece of paper, all of which objects will more clearly appear hereinafter.

In order that those skilled in the art to which my invention appertains may more fully understand the same, I will proceed to describe its construction and operation, ref-' erence being had to the accompanying drawings, forming a part of this application, and in which Figure 1 is a plan view illustrating my improvement; Fig. 2, a sect-ion at the line a a of Fig. 1; Fig. 3, a section at the line b b of Fig. 1, and Fig. i a detail side elevation of the inner face of the pad-frame.-

Similar numbers of reference denote like parts in the several figures of the drawings.

1 is the usual pouncing-machine arm, which is capable offree swinging movements in vertical and horizontal planes. 2 is a yoke rigidly secured to the end of this arm, and 3 is a shaft journaled within this yoke and having its outer end extended within a boss 4., projecting laterally from a box 5, said shaft being rigidly secured within said boss by means of pins 6.

From the foregoing it will be readily understood that the box 5 will partake of the movements of the shaft 3 around its axis, while at the same time this box can be bodily moved in vertical or horizontal planes, owing to the fact that it likewise. par-takes of the movements of the arm 1. Journaled within this box is the shaft 7, upon which latter is rigidly secured the pulley S. This shaft 7 projects beyond the box and has secured thereon the pad-block 9 in the manner presently to be explained. The felt portion 10 of the pad is secured around this block inany suitable manner, and a bar 11 is secured across the face of the block 9 by means of screws 12, which are driven through this bar and block into the shaft 7, so that the bar, pad-block, and shaft are practically integral. 13 is a hole extending from the top to the bottom of this bar, and'14 is a coil-spring within this hole. The sandpaper A is wrapped around the felt and its ends bear across the face of the bar 11, and a clamping-plate 15 is then forced firmly against the paper by means of screws 16, so that said paper will be held firmly clamped between the bar and plate. The function of the spring 14-is to throw the plate upward so as to release the paper when the screws 16 have been loosened.

17 is a frame which surrounds the pad, one side of the frame being supported around a suitable hub 18, which extends from the box 5, while the other side is hung around the extremity of the shaft 7, so that it will be clear that saidframe will rock independent of the pad.

19 are screws which are driven through arcuate slots 20 in the inner side of the frame 17 into thevbody of the box 5, the object of this being to hold the frame in position and at the same time to permit the frame to have Ia play about its axis for the purpose ,presently to be explained.

21 are plates secured to the ends of the frame 17 and depending therefrom, and 22 are blades which are pivoted at 23 to thelower extremities of these plates.

24 are angle-irons, to the lower horizontal legs of which are secured the blades 22,while screws 25 extend through the vertical legs of these irons and bear against the plates 21.

26 are springs whose ends are secured beneath screws 27, driven through the top of the frame 17, the free ends of said springs bearing firmly against the free extremities of the blades 22. These blades extend in a horithat the pad is slightly flattened in order to zontal plane toward each other, but are sep- I arated by a predetermined distance. The plane in which these blades extend is slightly below the lowest point of the pad proper, so that it will be clear that when the pad-sup porting instrumentalities are depressed so as to bring the pad into operation the blades will strike the hat before the latter is touched by the pad. I will therefore term these blades and angle-irons go-betweens, sincev theyalways are between the hat and the pad, and they perform such an important and original function that said term is very comprehensive and will be well understood in the art. Great care must be exercised while using hat-pounoing machines to so manipulate the pouncing-pad that it will pounce the hat uniformly and will not gouge the same or at times out in too deeply. By providing these go-betweens it becomes well nigh impossible to injure the hat in this manner, as I will now explain.

Referring to Fig. 2, the dotted line beneath the pad illustrates the narrow end of a hatcrown, and it will be observed that the pad is in contact therewith while the go-betweens are resting against the hat. As the hat-body revolves and the curves from a longer radius pass beneath the go-betweens the hat will not extend above the plane of the go-betweens, and the pad is accordingly depressed, thereby forcing the go-betweens upwardly until they come in contact with the stop-screws 28, which depend from the frame 17. As the hat continues to revolve the go-betweens will be depressed to normal position by the springs 26. The adjustment of the screws 25 28 determines the normal elevation of the go-betweens, as well as the extent to which they may be displaced by the hat-body, and it will therefore be clear that these go-betweens will always bear against the hat-body under a powerful spring-pressure and that whenever the pad is depressed toward the hat-body the go betweens will strike the latter and the pad cannot cut into the hat except to an extent governed by the yielding of the go-betweens until the latter strike the stop-screws 28.

Any suitable handle 29 is secured to the box 5 for the convenience of the operator.

It will be observed by reference to Fig. 2

accommodate the paper-clamping mechanism; but this peculiarity is no detriment, since the revolution of the pad is so extremely rapid.

The frame 17 also has an independent rockin g movement which insures the presentation of the go-betweens normally in a plane tangential to the hat-body, so that when the latter is revolving the contour thereof will not force against one of these go-betweens more than against the other, but will, on the contrary, cause the frame to swing until the correct position of the go-betweens is assumed.

, The speed-belt is passed around the pulley 8 in the usual manner; butI have not illus l trated any parts of the machine proper, since they are all of well-known construction and form no part of the present improvement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hat-pouncing machine, the combination of means'for supporting thehat, the rotary pad capable of being moved toward and away from the hat, and the adjustable go-betweens extending in a horizontal plane immediately below said pad and separated by a predetermined distance, said go-betweens partaking of the bodily movements of said pad whereby when the latter is moved toward the hat the go-betweens will strike said hat before the pad commences to operate thereon, substantially as set forth.

2. In a hat-pouncing machine, the combination of a rotary pad, with resilient go-betweens pivotally supported and extending in a horizontal plane immediately below said pad, and stops for limiting the movements of said go-betweens, substantially as set forth.

In a hat-ponncing machine, the combination of the rotary shaft, the pouncing-pad secured thereon, the frame pivotally hung and surrounding said'pad, the go-betweens pivoted to said frame and normally extending in a horizontal plane toward each other and immediately belowsaid pad, the springs supported by said frame and bearing-against said go-betweens, and the adjusting stop-screws by which the movements of said go-betweens are limited, substantially as set forth.

4.-In a hat-pouneing machine, the combination of the rotary pouncing-pad, the frame pivotall y hung and surrounding said pad and having an independent rocking movement, and the resilient go-betweens supported by said frame and normally extending toward each other immediately beyond the pad, substantially as set forth.

5. In a hat-pouncing machine, the combination with means for supporting the hat and the rotary pouncing-pad capable of being moved toward and away from saidhat, of the resilient go-betweens interposed in a plane between the pad and the hat and carried by said pad in its movements toward and away from said hat, substantially as set forth.

6. The combination of the rotary shaft, the pouncing-pad carried thereby, the frame surrounding said pad and pivotally supported, the blades pivoted to said frame, the angleirons secured to said blades, the adjustingscrews extending through said irons and bearing against the frame, the stop-screws depending from said frame, and the springs supported by the frame and bearing against said blades whereby the latter are normally maintained in a horizontal plane interposed between the pad and the hat to be pounced, substantially as set forth.
