MECHANISM FOR CLEANING BO OTOR SHOE UPPERS.

SPECIFICATION forming part of Letters Patent No, 368,105, dated August 9, 1887.

Application filed Februmy 17, 1887. Serial No. 228,129. (No model.)

To all whom it may concern:

Be it known that we, LEVI B. N EWHALLan FRANK B. NEWHALL, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Cleaning Boot or Shoe Uppers, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to mechanism for cleaning boot or shoe uppers, and the nature thereof is 'fully described and specifically claimed hereinafter.

Referring to the drawings, which accompany and form a part of this specification, Figure l is a plan view of a machine made in accordance with and embodying this invention. Fig. 2 is a side elevation of said machine, made partly in section to illustrate details of construction;

Figs. 3, 4, 5, 6 are details to be referred to hereinafter.

The driving-shaft A is mounted in and al-v lowed to be revolved in the frameB B, and on the shaft is a sheath, D,to receive the drivingcord from any suitable driving pulley. The frameB B hasits endsjournaled in the supporting-frame E, as shown inFig. 2. Projecting outwardly from the rear end of shaft A is an eccentric-pin,F,that enters a suitable hole in the block H, and the block H is arranged to permit vertical movementinitssupporting standard K, and from this construction the shaftA is given a compound movement. The pin F being eccentric with the shaft A,it follows that when the shaft is revolved either the pin must travel round the center of the shaft or the shaft must travel round the center of the pin, and taking advantage of this, we allow the pin to travel round the shaft during part of the revo lution, when it lifts and depresses the block H, as indicated in Figs. 3 and 5, to which end the block H permits the necessary vertical move mentiu standard K. During the other portions of the revolution the shaft must travel round the'pin, and this imparts a lateral vibratory motion to the shaft, as indicated by Figs. 4 and 6, and to permit this the frame B has its ends suitably pivoted in standard E, as shown.

The cleaning-pad is mounted on the forward end of said shaft A. To this end we provide the core a with a central longitudinal bore to receive the shaft A, as indicated in Fig. 2.

is surrounded by a piece of thick felt, I).

This core is preferably composed of wood, and This felt projects at either end beyond the core, and recesses are thus formed in which holding and'adjusting devices are positioned, which will hereinafter be described. At the end is a re-enforciug sleeve or thimble, w, composed of rubber or similar material. It gives a supporting but yielding quality to the pad at this point, and so prevents the pad from being jammed out of shape. It further serves to shield the end of the shaft and its incident clamps, and so prevents the shoe from being injured if accidentally or otherwise pressed against the end of the pad.

The pad is covered by a piece of plain cotton cloth, (I; but we are aware that chamoisskin or other textile fabrics would give good results, though not so economical. To facilitate the adjusting of the fabric onto the pad, and to insure its remaining there, we employ the metallic ferrules e f, which are secured to the core aand are threaded suitably to receive the nuts h k, as'shown in Fig. 2. .The ferrule e is further provided with an inside thread to engage a thread on the outside of shaft A, and so retain the pad on said shaft while in operation. In adjusting the fabricit is first wrapped about the felt. The edges at one end are put into clamp m and the nut 0 turned up, as in Fig. 2. The edges of the opposite end are put into clamp n, and thereupon the nut h is moved inward, forcing forward the clamp n, and so stretching the fabric tightly over the pad. It may be further tightened by a similar movement of the clamp it, whenever by use or otherwise it gets loosened.

In operation the upper is held in the hands of the workman and pressed upward under the pad. We are aware that the revolving or the vibrating movement ofthe pad may be dis-.

pensed with; but the pad will not last so long,

and will consequently not be so economical as when the compound movement is employed.

WVe claim-- 1. The combination of the core a, the felt I) 2. Ina cleaningpad for boots or shoes, and in combination the core a, the felt I), the fabric (1, covering the said felt, the holding devices, substantially as described, for one end of said 5 fabric, and the holding and adjustable devices, as the clamp n and screw 71, substantially as de scribed.

3. In combination, the pad, the fabric (Z, and the clamps m and a, and screws h 7c,for holding 10 and adjusting the said fabric to the pad, substantially as described.

4. In combination, the core a, the felt I), snrrounding said core and projecting at the ends beyond the core,whereby recesses are formed,

1 the fabric covering the felt, and the holding devices for said fabric situated within the recesses at the ends of the felt-covering, substantially as described.

5. In combination, the shaft, the core a, sur- 20 rounding the same and carried thereby, the cleaning material extending peripherally about the core, and the sleeve or thimble of rubber situated on the end of said core and extending beyond the end of the shaf t,substantiall y as de- 25 scribed.

6. In combination, the core a, the yielding cleaning material projecting beyond the said core, and the rubber piece 10 at the end of said core engaging with the projecting cleaning maoted frame B B, means for revolving the shafb 4 5 and the mechanism described for giving to the shaft a lateral reciprocating movement, substantially as described.

10. The combination ofthe core a,eo|nposed of wood or other suitable material, as set forth, the felt b,and the outer covering of textile fabric, the sleeve w, and means for securing the fabric to the pad, substantially as described.
