To all whom it may concern.'

Be it known that 1, Joux Lier, e citizen of the United States, residing ot Detroit, county of lllayne, State of vlichigan, have invented a certain new and useful Improvement in Space-Band Cleaners, and declare the following to be a full, clean, and exact description of the same, s ch as will enable others skilled in the art to which it pertains to make and use the same, reference. being had to the accompanying drawings, which form a part of this speciication.

This invention relates to space band cleaning devices and its Objectis a simple and efficient machine for automatically cleaning space bands employed in linotype machines or the like. A

During the casting o a line of type, the space bands become more or less leaded after a short period ot use, and it is nece,- sary that these bands be kept perfectly clean to produce the most satisfactory result.

As a great number of space bands are used that continuouslyY require being cleaned, itis an object of the invention to provide a Cleaning device that is not only automatic in act-ion but that operates in a manner whereby each space band is rapidly and thoroughly cleaned and delivered in a stack for ready removal from the machine.

These and other objiects and novel ieatures of construction are hereinafter more fiilly described and claimed Chorin in the accompanying iran Figure 1 is fr side elcvatiiin of the device embodying my invention. Fig. 2 is a sec` tion on line i12- of Fig. 1. Fig. 3 is a section on line yg/ of Fig. 1. Fig #i is en enlarged elevation partly in section of the polishing rolls showing the race-Way by means of which the bands are fed to the carriage. Fig. a detail of the brush for applying graphite to the polishing roll. Fig. 6 is a detail in perspective, showing a portion of the carriage, the race-Way for delivering the bands to the carriage, and the racefivay for receiving the bands from the carriage. Fig. is c detail' ot' the friction clutch.

In the prefe red Jr'orm shown, 1 is a suitable frame or casing provided with a cover niember 2. The cover member is fouled with a chamber 3 in win ch a, pair oi polishing rolls .enumerated parts.

with intermeshing gears 8 and 9, and the shaftextends through a bearing at the rear of the casing 1. Upon the outer end of the shaft 6 is loosely mounted a Worm Wheel 10 which is driven through the medium of the Worm 11 on a shaft 12 of an electric motor 13` the frame 1 being preferably provided with an inclosing casing for the Secured to the `Worm Wheel 10 is a circular casing 80 Within Which is an expansible ring regulated by the hand wheel 81, the Whole forming a friction clutch through the medium of which the Worm Wheel is secured to or loosened on the shaft. The ring is secured. to the shaft 6 and by turning the hand wheel 81 and expanding the ring to tightly engage the casing 80 the shaft 6 is made to turn through rotation of the worm wheel 10 by the motor. By such arrangement injury to the various parts is prevented in case the machine becomes accidentally stalled, as in such event, the casing S0 may revolve about the inclosed ring and thc shaft C and the parts operated thereby remain idle.

Mounted in bearings inthe casing 1 is an idler gear 14 meshing with a. gear 15 on the drive shaft 6. 0n the shaftyof the idler gear 1% a gear 1G meshing with e gear 17 on the shaft 18 mounted in bearings in the casing 1. which gears areI all driven through the medium of the drive shaft 6, which by reason of its connection to the motor has the highest rate of speed, While the shaft 1S has the lowest rate of speed. rThe carriage 19 for the space band is U shliped as shown more fully in Figs. 2 and 6, beting formed with two upwardly extending spiced members 2O and 21. The upper end of each member 20 and 21 is provided with a lug 22 having a sharp undercut upper edge 23 to engage the side extensions 31 on the sliding portion 46 of the band as hereinafter more fully described. At the rear edge the carriage is provided with a latterly extending flange portion '24 Which'rides in a: slot 25 provided in the cover member 2 and is held therein by the retaining plates 28 lforming a guideway for the reciprocation of the carriage. To the lower end of the carriage 19 is secured a stub shaft 27 connected by a, link 26 at the rear of the machine'to the crank on the shaft 18 as shown more clearly in Fig. 2. The rotation' ot the shaft 18, theret'ore reciprocates the carriage in the way 25.

Supported upon the front of the machine is an inclined raceway 30, in which the used space bands are placed in consecutive order, the projecting lugs 3l on the band ride on the way 32 provided upon each side of the raceway. Below the raceway 30 is a guide rod 90 which engages in the slot formed in the lower end of the space band. This guide rod prevents the bands from twisting in the raceway 30. In sliding down, the lowermost space band is picked up by the lugs of the carriage and raised by its continued movement between the polishing rolls 4 and 5 on the shafts 6 and 7, the direction of rotation is shown by arrows in Fig. 4. The roller 5 is carried in a yoke 33 shown by dotted lines in Figs. l and 2, the lower end of which is pivotedto the shaft 18 and this yokcris held in position by a spring 34 so that the polishing roll 5 is pressed into engagement with the polishing roli 4, the purpose of which is to allow the roll 5 to ldraw away from the roll 4 as the w413 to hold the raceway lwith the for wardl end thereof against the upper portionA 44 of .the raceway 30, as is seen more clearly inFig. 6. As the carriage 19 moves upward -with a space band therein, the race way is raised by the upper end of the band, and, as the band passes upward with the carriage, the end of the raceway 40 drops into .the slot 45 in the space band whereby, on the return of the carriage to its lowermost position, the upper-'sliding portion 46 of the band engages -the raceway 40 and, as the carriage continues to descend it draws away from the band which is thus delivered onto the inclined raceway and down which it slides. The continuous operation of the carriage therefore, takes -a band from the raceway 30, raises it between the polishing rolls and finally delivers it onto' the receiving raceway 40, As the receiving raceway becomes filled, the operator may turn the raceway on its pivot and strip the,

cleaned space bands therefrom.

The polishing rolls may be of any approvedtype for the purpose, but are preferably of metal, which is grooved or scored on the face at an angle to the longitudinal axis. These grooves are preferably filled with graphite or other material suitable for the purpose. The bottom of the chamber 3,

-ably provide a receptacle 60 near the i? in which the polishing rolls are situated, is formed in a manner to hold powdered graphite or other polishing powder, and the polishing rolls are continuously supplied with fresh powder by means of brushes 50, im shown more clearly in Figs. 1, 4 and 5. The bristles forming the brush are mounted in a head 5l, through which a rod 52 extends pivotally supported in the walls of the chamber 3. To the outer end of the rod is an operating lever 53 extending down ward below the bottom of the chamber and inwardly' toward the cover plate 2, terminating in a curved portion 54 positioned in the path of movement ofthe portion 24 of the carriage 19. The normal position of these curved ends of the operating levers is shown in Fig. 1, where they are seen to be practically in contact, and the bristles of the brush will then lie in the powder pro-- vided in the bottom of the case ai, cl 3. Upon the upward movement o t riage, the rounded upper end 55 oil. the c tion S24- engages between the curved ends of the levers forcing them apart whmh rotates the brush head upon the pivots provided and brings the powder covered bristles in Contact with the polishing rolls and thus vsupplies fresh powder thereto. As the car,-

riage descends the brushes fall back into the n powder by reasonof the action of the coil springs 56 tending to hold the brushes cui of Contact with the polishing rolls. At cach operation of the carriage the rolls are thu. supplied with fresh powder.

During the polishing operation consider-v able polishing powder willfall through the opening in the bottom of the Vchamber through which the carriage and space band reciprocates and, to prevent waste I prefer of the machine to receive the powder wh may be again placed in the chamber through an opening provided in the o thereof.

Iliff From the foregoing description it he. comes evident .thatthe device is of simplifand compact construction and is automatic in operation, it simply being necessary in supply the raceway 3Q with the used bands H5 and to remove'the cleaned bands from the raceway 40. The band iscariied to and from the polishing rolls by the carriage is thus guided in its movement.

Having thus brieiiy described my inves 5 tion, what I claim and desire to secure h 'f Letters Patent of the UnitedStates is- 1. In apparatus ot' the kind described. polishing device, a l'aceway for holding a plurality of space bands, a reciprocahif holder` or carriage adapted to co1 ..'ecutively remove the bands from the raceway and suhmit each to a polishing operation by thel polishing device, means for positively recip rocatmg the carriage, and automaticinean for removing lhe polielied hunde from the holder.
