For retaining the carrier in a In the drawings, wherein like reference lowered position, a resilient member 22 is characters denote corresponding parts provided, which engages the extension 16 throughoutthe severalviews: Figure 1 is and the carrier 14, as clearly shown in a. plan of a blacking applying machine Fia.2. in accordance with this invention. Fig. 2 The manner in which the daubers apply I is'a side elevation. Fig. 3 is a longitudithe cleansing liquid or the blacking to the nal section broken away. Fig. 4 is a. pershoe is as follows: The daubers are in the spective view illustrating the means for supposition as shown in Fig. 2. the shoe is plying the cleaning liquid and polish to one passed downwardly upon the platform 1 unof the daubers.

biachlng, as the shoe clears the dauber 7 it will engage the dauber 8, so that the opposite side of the shoe will have the cleansing medium or hlacking applied to the shoe. The operation of the dauber S is the same as that of the dauher 7. the dauhcr 7 operatin upon one side in front of the shoe, and the dauher 8. operating upon the other side in front of the shoe. After the shoe clears the danbcrs, the springs return them to normalposition.
- ll'hcu thc machine. is used, the shoe is first. passcd over the platform I for an application ot the cleansing liquid and afterward again passed over the platform to receive the blur-king and after the blackin; has been applied to the shoe. the shoe is polishcd by a suitable machine or manually, if desired.
The mechanism for supplying the cleansing liquids and the hlacking to each dauber is the same, so therefore one only will be described, as the description of one applies to the other. One of these mechanisms is arranged at one side of the machine, and the other at the other side of the machine, and in operative relation with respect to its dauber. Each of said mechanisms includes av casing 23, constituting a cleaning liquid containing reservoir, preferably cylindrical in contour and having an open top. A supporting frame Q-l depends from the platform- 1 and to which the casino $33 is cemnected through the medium of the lugs 25 and holdfastdevices 26. The open top of (licensing- 23 is closed by a shiftable incur her 27 liar curved arm 28, which ex; tends in the casing 23 when the member 27 is moved to closed position. The member 27 is provided with a pair of lugs 29. which are pivoted, as at. 30, to the end of the casing 23 and attached to the member 27 is one end of a coiled spring 31, the other end of the latter being; attached, as at 32, to the casing The member 27 with the exception of its arm segment-shaped in contour and is arranged against the periphery of the casing 22-. The member 2?. partially closes the open top of the casing; 23, the remainder-of the top being closed by a shit'tablesegmentshaped plate 33. Vliliil the casing 23 1s arrange a body of cleaning liquid 3 the level (if which extends above the lower end of the arm 28. the latter constituting a support for a supply roller 35 carried on the lower end of a crank arm 36, which extends through and is fixedly secured to the plate The supply roller 35 is arranged at one side of the inner end of the crank arm 36 and is mounted upon a spindle 37, which is jourualed in the arm 36, and in an angular bracket 38, and between the bracket 38 and the arm 36 is positioned the roller 3!. The c'ank arm 36 projects from a sleeve 39, which is carried by a hollow shaft 40 mounted upon a bearing 41. Connected to the outer end of the shaft 40 is a crank arm 42. h-Iounted upon the bearing 41 at one side of the shaft 40' is a hollow shaft 43 provided at its inner end with a collar :14, and at. its outer end with a. crank arm 45. Projecting from the collar 4% is a crank arm 46 carrying a receptacle 47 movided with blacking 48 inthe form of paste.
Carried by the frame 24 is a casing 49 adapted to receive the receptacle 47 and whi h is closed through the medium of a con-r carried by a shaft 51 journalcd in a bracket which projects from the wall of thc casing: 49. The shaft 51 is provided with a weighted arm 5-l. which retains the cover in an open position when the receptacle atT is shifted from the casing 49; when the cover 50 is in an open position. the wcightcd arm cxtcnds through a slot in the wall 53, so that when the receptacle 47 is moved back into the casing the arm 54 will be engaged thereby shifting the shaft, 51 and mating the cover to closed position. The crank arm 42 is pivotally connected at 56 to a vertically disposed handle 57, which extends through an inclined keeper 5S. The crank arm 4-5 is pivotally connected. as at 59. to a handlc G0. which extrnds tln-aupgh'an inclined keeper It: will he assumed that. the (lauber is to be supplied with a liquid cleaning medium.
The supply is had, as follows: The handle 57 is pressed downwardly which carries the crank arm 42 ther with and rocks the shaft; 40, when the shaft- 40 is rocked. the crank 31'; is elevated. As the crank moves out of the receptacle 33. the member 9'? is Forced outwardly whereby the roller 35 will be moi-ed over the casing 23, the member 27 assuming the position shown in dotted lines in Fig. 3. By operating the llillldl-l- 57, the roller 35 is brought to engage the felt or fabric 1i and by moving, the handle 57 toward the uppe; end of the platform the roller is carried across the feltcr fabric 11 thereby applying;- the cleansing medium thereto, the position. of the roller being shown in dotted lines in Fig. 3. The member 27 is maintained in open position hy the spring; 31. By pulling the handle in an opposite direction, the shat-'1 -10 is ruched so as to swing the roller 35 haul-I into the easin the roller moves to ard the ing 2; :5 colors the tie member 2? into :2 p0
portion oi the open top of the casing 23. When the member 27 is in the position as shown in Fig. 3, the plate 3:,
closes the remaining portion of the open top of the casing 23.
It will be assumed that the dauber should be supplied with blacking. The handle .61 is 'moved downwardly, thereby rocking the shaft 4st and swinging the receptacle at? out of the casing 49 and on a further movement of the handle the blacking is drawn across the felt or fa rie 11 thereby supplying the fabric with the required amount 0 By pulling the handle 61 in an opposite direction, the receptacle 47 is restored to the casing 49.
The blacking 48 is carried by a box 63, which is pivoted, as at'64, in the receptacle 47 and is engaged by a spring 65, which forces the box 63 outwardly so that the blacking will engage the fabric or felt 11 when the receptacle is shifted out of the casing 49 to supply the dauher with blacking.
