FELT-HAT AND LIKE FELTING MACHINE.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed September 8, 1911. Serial No. 648,352.

To all whom it may concern:

Be it known that I, ALBERT TURNER, a subject of the King of Great Britain and Ireland, and resident of Denton, near l lanchester, England, haveinvented new and useful Improvements in Felt-Hat and Like Felting Machines, of which the following is a specification.

These improvements refer to felt hat or like felting machines of the type commonly called bumpers which consist of a single fixed scoop-like receptacle and an arrangement of two lever arms fitted with broadfaced downwardly extending blocks, commonly called hammers, the hat bodies to be fitted being placed in the receptacle, which is supplied by hand with acidulated hot water, and the hammers by means of a revolving shaft and cranks being designed to intermittently and alternately act on the hat bodies to be treated.

The improvements have for their objects (1) to construct a machine of the type named which will allow of a more efficient felting of the hat bodies than the ordinary construction of machine, (2) to provide a machine which is practically two machines in one and which will occupy less floor space than two separate machines, thereby economizing room and to provide a machine in which the action of the hammers can be regulated to suit the hats to be treated.

Upon the accompanying drawings, Figure 1 illustrates a side elevation and part transverse section, and Fig. 2 a plan of a machine embodying the invention.

According to the invention, the improved machine comprises two scoop-like receptacles a a formed integral with each other, the vertical end walls a being arranged back to back, see Fig. 1. The receptacles are constructed chiefly of wood, with metal end frames common to both, and cross rods to hold them together. In the floor of each receptacle are the usual drain holes a Mounted in bearings b is a shaft 0 and loosely mounted upon such shaft is a series of levers or double-armed blades (Z. There are preferably four of these levers or blades all of equal length and extending from end to end of the machine. At each extremity each lever is provided with a downwardly projecting wood (oak) block or hammer e, which on two of its faces is curved longitudinally to correspond with the curvature of the floor of the receptacle in which it is designed to work. These blocks are narrower in width across the curved face than the ordinary blocks, the ordinary blocks being about twelve inches wide and the improved blocks about seven inches wide. At its extremity each block is stepped like the ordinary hammer to form a suitable surface for engaging the felt hat bodies. Mounted in bearings f is a further shaft 9 and upon such shaft is a series of eccentrics it, by preference, one for each felting lever. The strap of each eccentric is connected to its lever through an adjustable connecting link 2'. Upon the shaft g 1s also mounted the usual driving pulley j, and also, if desired, fly wheels 70.

The floor of each receptacle a a may be provided with a jacket, as shown by broken lines at a in Fig. 1, into which, when the machine is in use, steam may be admitted. The part a of each end wall is hollow and steam heated and such part is made of metal (brass). In practice, this is found sufficient for the purpose of keeping the receptacles in a warm condition.

In proceeding to use the machine the receptacles are each supplied with acidulated hot water through a spray pipe j, Z from a heated boiler or a tank Z. Steam is also supplied to the jackets at Hat bodies are placed in each. receptacle, after which the driving belt is placed on the driving pulley and the eccentric shaft set in motion. The effect of the shaft rotating is to cause the levers d to oscillate about their axis, and the hammers e to act upon the hat bodies in the two receptacles. As the hammer at one end of a lever moves down to act on the hat bodies within one receptacle, the hammer at its other end is raised away from the hat bodies in the other receptacle. With the increased number of hammers and such hammers of less width than the ordinary hammers, the hat bodies receive a greater number of impacts than in the ordinary machine and the action of the hammers is distributed to better advantage. A further advantage is that by applying a hammer to each end of the levers the hammers are balanced and, by operating the levers by mechanical means, the action of the hammers upon the hats to be felted is determined by the power transmit-ted through the eccentrics and not by the weight of the hammers as in known felting machines. To afford the best results it is preferred that the eecentrics be set a quarter of a circle in ad rance of each other in the order of their nmnber.

The machine will preferably have the usual slotted and curved guards m for the ends of the levers. The water in the receptacles, and squeezed out of the hat bodies, will pass into a tank or from whence it will be returned to the heater Z by a pump or injector. The water of condensation from the jackets a may also pass into the tank a. In the tank Z may be a filter or strainer for arrest ing any of the fur or kemps in the water, prior to its entering the tank Z.

It will now be seen the improved machine constitutes two machines in one, thereby eeononiizing floor space, as well as power, and that, with the receptacles kept warm and constantly supplied with hot liquor, the felting of the hat bodies will be greatly improved and e tpedited.

Yl hat I claim is A felt hat felting machine comprising two scoopdike-receptacles formed integral, a series of levers common to both receptacles a felting block or hammer of comparatively narrow width across its working surface secured to each end of each lever and extend ing down int-o the receptacles and one hammer of each lever balancing the other hammer, means for pirotally supporting the levers and hammers side by side and means for positively operating the levers to oscillate them, such means being capable of raising and lowering the levers one after the other and means for circulating hot treating liquor through the receptacles, substantially as herein set forth.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
