TO ALL WHOM IT MAY CONCERN Be it known that I, WILLIAM HUMPREYS, Jr., of Cold Spring, in the county ofPutnam, and State of New York, have invented anew and useful Machine for Stretching Hat-Bodies; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a sectional view of the machine showing the shape and position of hat before the stretching begins. The hat is shown in red.

Figure 2 is a side view of the machine.

Figure 3 is a back view of the machine with the stand g and weighted lever z removed.

Figure 4 is a top view of the machine with'some of its parts shown in section.

Figure 5 is a top View of cap-piece marked D.

Figure 6 isa section showing the shape of the hat wher? stretched, and the position ofthe levers and parts of the machine that are directly connected with' the stretching.

Figure 7 is a bottom view of the cap-piece D. v w

In some of the views given on drawing, it will be observed that au tue parts ot' theV machine are not shown that are seen to exist in other views. It will also be seen that some of the parts are not in their true position; as in the case of'iigs. l and li, the levers F Gr and rods H are one twenty-fourth of the circumference out of their proper place. The object of this is to avoid confusion and to allow the essential and important parts to be seen, that the principle of the machine may be easily understood.

Similar letters of reference in all the views indicate corresponding parts. s

The principal object of this invention isto stretch wool, fur, or other hats, into the desired shape andsize before they are blocked, that they may retairli their shape when worn, and also to overcome the diliculty that exists in stretching or breaking down the tip, so as to prevent the centre ot`the crown from rising or running to seed,as termed by hatters, which is caused by there being' too much material or afullness in and around the centre ot' the crown, that part not having been properly stretched.

The invention consists, iirst, of a. cap-piece for the inside of the hat, so made as to come in contact with the hat at that part of the body next to the brim, in combination with a cylindrical cap-piece that drops over the outside of the hat and comes in Contact with the hat at the same part on the outside as the inner cap-piece does on the inside, thus securing theV hat firmly in its position, thereby preventing its slipping while being stretched; second, in arranging a series of levers, Working on half journals, and connected to the inner cap piece, thereby bringing the centre of motion as near as practicable to the ybreaking point of the brim next toi the body ofthe hat, in combination with the ieversior fingers and springs for holding the edge of the brim while the brim is being stretched; third, in the arrangement of a. series of'adjustable pieces, connected to the cylin` drical cap-piece, dropping over the outside of' the hat, andcoming between the series of levers, for the purpose of increasing the stretching ofthe brim, so that the brim will retain its proper shape when taken olf themaclline; fourth, in the arrangement ot' a series of levers or fingers, connected to the inner cap-piece, in combination with the circular wedge-piece and its connections, for the purpose of stretching the body and crown of the hat; fifth, in the arrangement for raising and lowering the cylindrical cap-piece, and the adjustable pieces connected to it, at the proper time, and also the manner that it is held position when down and when up; sixth, the arrangementl for preventing the falling, by accident, ot' the cylindrical'cap-piece and its connections, by the machine not'. stopping at the proper time, or by starting too soon.

To enable those skilled in the art to make and use my invention, l will proceed to describe its construction and operation with reference to the drawings. Y

.The llfmmer of lVoTcz'ug the llacht'ne.

The cylindrical cap-piece E, with the adjustable pieces O, are moved up to the top of the guides in standards B, by the pin m on wheel U coming into the hook on the end of the rod c, and carrying it around until the under side of the rod c comes in contact with the shaft R. At that point the machine stops, the pin n on wheel U having already come in contact with the projection on rodf at g, causing the weighted lever Lto pass its perpendicular, thereby changing the belt from the fast to the loose pulley, also bringing the hand-lever e in such a position that the projection t on lever is brought under the projection o on rod Z when it is raised to its highest point. rlhe object of these projections on lever e and rod Z is to prevent the falling, by accident, the cylindrical cap-piece E and its attachments, bythe machine not stopping at the right moment or by its starting too soon. This part of the operation, as shown on drawing, is a little in advance ot' their proper position in rel'ation to the other parts of the machine. It is to be understood that the-machineis stopped; that the cylindrical cap-piece E, with the adjustable pieces 0, are at the top ofthe guides in standards B; that the ends of the levers Y have tripped the catches 7' and carried the rods Z Z up to their highest position; also, that the rod c is hooked on pin m; that the pin-m, with the wheel U, is a little buck on the circumference of its travel, so that the under side of the rod c is in contact with the shaft R; also, that the rod LZ has not dropped into that part of the circumference of the wheel U that is cut for its reception. It is also to be borne in mind that the.

weighted lever h has been carried past its perpendicular by the pin fn, and that the belt is on the loose pulley,

the projection t on lever e is under the projection o on rod Z. The other parts of the machine being in 'their proper position, asjshown Aon the drawing. it'is readv for stretching a hat. The levers` and the levers or lingers G, with the cap-piece D, form a frustum of a cone, similar in shape to a hat before stretching. The hat 'is dropped on, as shown on iig. l, (in redi) vthe hand-lever e is pulled into the position shown on iig. 2; the belt `is brought on to the fast pulley, andthe machine starts; the crank R begins to revolve in the direction shown by an arrow; the lever P rises and lifts the circular plate I with the rods H, causing the levers or fingers G to close .upon theedge of the brim of the hat against the edge of the levers F. At that moment the cylinder cap-piece E, with the adjustable pieces O, has been brought down to the position shown in iig. 1, which is done in the following manner: The machine being started, the wheel U begins to revolve; the rode having come in contact with the shaft R, can go no further; the pin m moves out of the hook, and the rod c is drawn back to the position shown in iig. 2. By the 'weight of the cylindrical cap-piece E-a-nd its attachments, the rod d-falls into its place, as shown on fig. 2, just before the rod c becomes disconnected from the pin m, for the purpose of preventing a too rapid falling of the cylindrical cap-piece E with its connections. The weight of these parts in coming down throws the catchesj until thelower ends of the rods Z Z are in their'lowest position; then the springs throw the catchesj in the position shown on tig. 2. rlhe lever l? continues its upward movement, causing the levers F to move up to a horizontal position, as shown on fig. 6. That part. of the brim that lies between the levers F comes in contact with the adjustable pieces OV before the levers F 'reach their horizontal position, as shown in iig. 6, thereby causing the brim of the hat to' stretchnround the under side of the pieces O.V '.llhe brim is also stretched by the levers F in moving up to their horizontal position. The ends of these levers are farther apart in their horizontal position than when they are in their lowest position. The levers or ngers Gr hold the edge of the brim secure, froml the fact that the resistance arising from the stretching requires u. greaterv resistance tb move the levers up, and this being vtransmitted by the rods I-I to the end of levers or iingers Gr, causing the other ends to press harder' against the edgeof the brim and levers F, thus holding it firm and secure; and as the circumference of the brimincreases. by the upward movement of the levers, the brim is strainerdor stretched in the direction from the centre to the circumference; and when in contact with the adjustable pieces O it is stretched in the direction of its circumference. The adjustable pieces O are lowered 'clown for heavy hats, and are raised up for light hats, by the bolts and nuts marked u.I The inner or outer end may be raised or lowered, as maybe 'required for stretching. On the inner `circumference of the brim, next the body of the hat, there will be a sufficient band formed by the lower edge of the cylindrical cap-piece E, in connection with the inner ends of thc pieces O and levers F, that wool hats will not require any further banding or blocking before they are put on the nishingblock for inishing. In the upward movement of the circular plate I it comes in Contact with thelower end of sleeve K; and as its upward movement continuos, it forces the sleeves K J, rods L, and the circular wedge-piece M, up to the position shown in g. 6, thereby forcingv the levers or ngers N apart, which stretch the body andy top of the'hat, as shown in red `in iig. 6. At this point of the operation the hat is stretched; the crank R is moved round to its upper position, and as it moves on to its lower position the lever P moves down, bringing the circular plate I and'its connections with it; the

circular wedge moves down; the levers or tin'gers N are thrown into their position, shown in iig. 1, by the` pressure of the hat. Then the circular plate I has moved down so as to leave the sleeve K, the pin m comes into the hook on rod c and carries it along, thus moving the shaft W and levers Y and a, the levers Y having a slot in the end of suilicient Vlength to give the necessaryr motion for tripping the catches Before lifting the.

rods Z Z and the parts connected thereto, the cylindrical shell and its attachments are raised to their highest position, and reach it at the moment the crank R arrives at the point shown in tig. 2. The machine at this point is stopped by the pin fn. having struck against the projection q on rodf, thus throwing the belt from the fast to the loose pulley. The levers F, having reached the position shown in iig. l, cannot go farther down, they being held in thisw position by the upper end coming in contact with the cap-piece D. The circular plate I, not being quite down to its lowest position, causesthe levers or fingers G to open, as shown on iig. 1, when completely flown. The hat is then taken olf, and another one is dropped on; the hand-lever e is again brought Ainto the position shown in fig. 2; the machine starts again and stretches another hat, thus stretching all uniform and alike.

The fulcra of the leversF should be placed as near as practicable to the breaking point of the brim, so

-that the centre of motion of the levers shall be the point ofibrealting the brim. To accomplish this I uselialf journals, as seen in fig. 1, by which I am enabled to carry the centre of motion much nearer to the-edge of the base-plate D, or breaking point, than would be the case if ordinary or whole journals were used.

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

1. A series of stretchers O, in combination with the levers F, for the purpose of overstretching the brim, substantially as described.

'2. Mal-:ing the said stretchers adjustable vertically, so as to regulate the extent of stretching, substantially as described.
