BLAST DEVICE FOR SHOE-POLISHING MACHINES.

Specification of Letters Patent.

Patented Sept. 11, 1917.

Application filed June 10, 1916. Serial N 0. 102,899.

To all whom it may concern:

Be it known that I, Gustavo ESPINOSA on DB8 MoN'rnnos, a citizen of Mexico residing at El Paso, in the county of lill Paso and State of Texas, have invented certain new and useful Improvements in Blast De vices for Shoe-Polishing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a blast device for a shoe polishing machine and has for its principal object the production of a device which is so constructed as to apply polish to a shoe and then to dry the same and atterward polish the shoe, thus dispensing with the necessity of the employment of the ordinary brushes and other paraphernalia now in use for the purpose.

Another object of this invention is the production-of a l. last device for a shoe polishing machine wherein the base has a ban dle formed thereon so as to permit the same to be easily lifted,while the motor housing carried upon this base permits the entire device to: be easily lifted and moved to a position desired so as to facilitate the polishing of shoes.

Another object of this invention is the production of a blast device for a shoe pol-- ishing machine wherein the funnel is de mountably carried upon the motor housing so as to direct the air currents from the motor housing to the shoe u on which the polish' is being applied, this unnel being adapted to be removed when so desired for applying a brush to the motor shaft, whereby" the brush may either apply the polish to a shoe or burnish the shoe afterward as desired.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a side e evation of the blast device for a shoe polishing machine.

Referring to the accompanying drawings.

by numerals it will be seen that 1 designates a base plate which has the handle 2 formed upon its rear end and extending for a considerable distance thereabove. This handle 2 has a sleeve 3 formed upon one side thereof and through the handle 2 and sleeve 3 there extends a bore 4 for the reception of the conductor wires 5 wt ich extend therethrough. The motor 6 is mounted upon the base 1, as shown in Figs. 2 and 3 and is held in a fixed set position by means of the screws 7 which pass through the base of the motor 6 into engagement with the base plate 1. The wires 5 are connected to the motor 6 so that a suitable supply of electricity may be supplied to the motor for running the same. It is, of course, obvious the v; suitable form of a motor may be ..mployed either of a direct or alternating type and also of any desired size.

The motor housing 8 is substantially circular in cross-section at its central portion, although it tapers toward its end, and is mounted upon the base plate 1. The straight side walls 9 extend from the central portions of the housing 8, depending for a considerable distance therebelow and having the horizontally extending base flanges 10 formed thereon, which flanges rest upon fhe base plate 1. The retaining screws 11 portions of the motor housing pass through the base flanges 10 into engagement with the base plate 1 and thus fixedly secure the motor housing 8, in a set osition upon the base plalie'l. 'It should he noted that the motor housing and the walls 9 thereof are formed of any suitable material, preferably metal, although they may be of any suitable substance so as to minimize their weight when applied to the base plate 1.. Since the motor housing 8 is circular at its cen ral portion sufficient space is provided for the accommodation of the motor 6, as shown in Fig. 2. The rear end of the motor housing 8 is provided with a number of intake openings 12 so that when the motor is running air may be sucked into thednterior of the motor housing by m ans of the'fan 13 mounted upon ihti motor shaft 14. This fan 13 may be retained in a set position by means of the set screw 15 as shown in Figs. 2 and 5. As the ends of the motor housing converge the air being drawn in one end will be condensed by the opposite reduced end and discharged with considerable force therefrom. lhis last-mentioncd end of the motor housing 8 is provided with an annular collar 16 to receive the funnel. The funnel 17 has a collar 18 which is adapted to demountably fit upon the collar 16 of the motor housing 8. The collar 16 of the motor housing 8 is provided with pins 19 which are-adapted to fit within the bayonet slots 20 of the collar 18 of the funnel 17. Thus, it will be seen that the funnel may be applied to the collar of the motor housing 8 so as to permit the pins 19 to be directed into the slots il after which act.on the funnel may be turned to one side, thus permitting the pins to rest within the inner portions of the slots 20 and thus hold the funnel from being accilvnlally displaced when in use. This funnel l7 tapers toward its outer end, as shown clearly in Fig. 5. although the outer end is flared, as shown at 21 comprising a blunt bearing surface, provided the end of the funnel con'ies into engagement with the shoe which is 11 ng polished.

The brush used for applying the polish to the shoe comprises a shaft 22 having an enlarged inner end 2? in which there is forn'ied a socket 2-1. square-d n cross-section, as shown in Fig. 11, so as to lit upon. the square end 25 of the motor shaft 14. The set screw 26 is carricd by the enlarged. inner end 23 of the brush shaft 22 so that after the square end B5 of the motor shaft 14 has been inserted in the square socket 24, the set screw may be turned so 15 to bind upon the motor shaft it and thus hold the brush shaft 22 in a fixed engagement therewith, whereby as the motor shaft rotates the rotary motion will be imparted to the brush shaft 22. This brush shaft 22 is provided with a reduced This sorkct 24 is outer end 27 upon which are positioned the washers 28 and 29. 'lhefahric sheets 30 which constitute the brush are positioned upon the reduced end 27 of the brush shaft 22, being interposed between the washers 28 and 29. The retaining nut 31 is threaded upon the outer end. of the reduced end 27, thereby holding the. washers .28 and .29 and the fabric sheets 30 in fixed engagement with the outer reduced end 27 of the brush shaft 22. Thus, it will be seen that polish may he applied to a shoe by means of the fabric brush 30 for after the polish has been applied to the brush and the same is being rotated by the motor the brush may be positioncd upon the shoe and the polish will be evenly and thoroughly distributed upon the surface of the shoe. As soon as the polish has been applied to the shoe the brush shaft 22 may be detached from the motor shaft 14, after which action the funnel may be placed upon the collar 16, as shown in Fig. 5. The motor may thenbe again started so that the air being discharged from the funnel may quickly drv the polish and thus dispense with the necessity of using the customary articles now employed for accom lishing this function.

After the polisli has become dry the shoe may be easi y burnished by means of the soft brush 32. The brush shaft 22 is provided with an enlarged inner end 23' in which there is formed a square socket 24' so as to receive the square end of the motor shaft 14. The set screw 26 will detachably retain the brush shaft 22 in ei'igagomcnt therewith. Upon the forward end of the brush shaft 22 there is carried a coil spring 33 by means oF the rivet 34 which secures the coil spring to the forward end of the brush shaft 22'. The opposite end of the ill spring 33 is secured by means of the pin 35 carried by the cup 36 upon which the soft brush 32 is mounted. The yiuldahle rubber boll 37 is mounted upon the forward, end of the brush shaft. 22' so as to overhang the spring as well as the brush 32. Thus, it will be seen that if this'brush is used for applying polish to a hoe the yieldable boll 37 will prevent the polish from being thrown cit'hcr upon the operator or the pa tron. Furthel'morc, it will be seen that since the brush 32 is yieldably mounted sun-c the spring supports the same in burnishing a shoe it will yield slightly as the shoe is being rubbed and thus prevent the shoe from being rubbed too vigorously, which action would remove the polish which has been prior-1y applied thereto.

From t e foregoing description it will be see rthat' a very elhcient shoe polishing machiaehas been provided, which is so conspuctbd' as to very quickly polish a pair of s ions," owing to the fact thatthe polishing means now commonly employed for accomplishing this purpose are dispensed with and owing to the rapidity with which the.

fan housing havin tapering ends will constitute a director or the air which is being blown upon the shoe for dryinthe same. lhus, it will be seen a shoe p0 ishing ma chine has been provided which will ciently accomplish all purposes as set forth, and which is comparatively simple in opera: tion, cheap in construction, andformed of a minimum number of parts for the purposes specified.
