a the following description, in connection with the accompanying drawings, is 'a specification, like reference characters on lthe draw'- ings indicating like parts in theseveral This invention relates to buing machines and is herein illustrated in connection with a. `machine for buliing'parls of boots and In machines of this class it has been customary to pass the stock, for example counters, box toes, etc., `betweena feed roll and-a buiin roll which are located approximately in t e mouth of a suction conduit and to provide in the rear of the rollsa brush to remove from the bufi'ed Stock the dust generated during the buiiing operation. With this construction, however, theremoval of dust has been ,incomplete since a certain amount of dust clings to the buffed surface despite the action of the brush and is therefore not. inposition' to be swept out by the'current of'a1r. Moreover, from theA fact that the brushhas been arranged in proximityl to the buiiing roll, the current of air produced by the suction apparatus has been blocked at just the should have been permitte free passage.

In-order to remedy these'and other defects, one 'feature of the present invention consists in la machine of the class described of a striker arranged to deliver upon the buied article va series of blows which serve tov disengage thev dust from .the surface ofy the article and to raise it into position to be 'swept away. This striker may be placed in lbutling' roll is but momentary.

Another feature of the r`invention consists of a perforated' guide arranged at an angle -Specicationof Letters Patent. Application le'dMarch 7 1913. Serial No. 752,752. i

it back toward the operator into position .to be readily removed from the mach-ine.

These and other features of the invention, including certain details of construction and .combinations of parts will be set forth in connection with an illustrativemachinc and pointed out inthe appended claims.

Referring now to the accompanying drawings,-l1`igure 1 is a longitudinal vertical sectionv through a machine in which the present invention is embodied; Fig. 2 is a front elevation of the machine, and Fig. 3 is a side elevation of the machine.

The butiing roll l, herein shown as-a split. roll, is fast to a shaft.v 3 which is rotatably mounted in slidable bearings the positions of which may be controlled by adjusting screws one of which is shown at 5. The feed` roll 7 which has a facing of rubber or other yielding material is fast to a shaft 9 which is rotatable in fixed bearings. The plane which `includes the axes of both rolls is inclined; and, slidably mounted upon the frame of the machine, ina plane parallel to this one, is a late 11 which is adjustably heldbetween tlie upper pair of screw bolts 13 and the lower pair of screw 'bolts 15 so that the position ofsaid plate may be ad# justed for a purpose presently to be de-v scribed.v A presser 17 which extends in a direction oblique to the direction of feed and within a short distance of the bite of the rolls is adjustably held in position on the plate 11' by screws .19 which pass through l by the mouth of a suction conduit, said condnit'heing connected with a suction apparatus 27 of any approved type the kmovable Patented Nov. 11, 1913.

cylindrical brush. Belowthestriker aud rolls is a perforated gu1de`37 arranged at an angle to deflect the piece of lstock after "it has pass-fed' the-'striker and turn it back toward `-the front of the machine in position to be removed readily. Thisguide has `flaring wings asshown in Fig. 2 and fills the lower portion of the mouth of the dust cony duit. being fastened to the side walls of said conduit by screws 3S which pass through carsl ou said guide and into said walls. The upper wall 23 of the suction conduit forms a' cover which pivoted to the frame at 37, and adjustably mounted on bosses on this cover is a plate 40. A buiiing roll operated at high speed carries with it in its revolulion a cloud of dust. a portion of which is ".lected .l'roll'i the fronty oil' the u'lachiue. The plate l0 is 'adjusted as close aspossible to the periphery of the roll 1 and serves to dctlect this moving cloud and direct the dust into the suction conduit. It also serves by closing the space between the roll and the hinged cover to concentrate the draft.

'Referring now to Figs. 2 and 3, the shaft 3 upon which the buiiing roll is mounted carries a pulley 41 over which and over a pulley bristlesandvconsisting of a segment of al 413 on the counter-shaft ltdpasses a belt 47,'

a belt tightener 49 operate by a handle 51 .being provided for maintaining the tension 'on said belt. On the shaft 29 of the fan is a pulley 53, and on the shaft 31 of the striker is a pulley 55, said pulleys being driven by a belt 57 which passes around said pulleys and around a pulley 59 on the counter-shaft, a belt tightener 61 operated by a handle 63 being provided around which the belt 57 also passes'. From the connections indicated above it will be evident that the bufling roll, the striker and the fan will all be rot-ated at a speed greater than that of the counter-shaft 45. In practice the buiiing roll is rotated at from 3000 to 4000 revolutions per minute.

Thel feed roll is driven at comparatively low speed by the following mechanism:

Fast to the counter-shaft fifi-is a sprocket 61 around which and around a sprocket 63 on a shaft 65 passes a chain 67. On one end' of shaft 65 is a small gear 69 which meshes-with a large gear 71 on one end of another shaft 73 the other end of which carries a small sprocket 75; and around the last named sprocket and a sprocket 77 on the shaft 9 of the feed roll passes a chain 79.

A A roll Slearried by an adjustable bracket serves totighten this chain; anda similar roll 83, similarly mounted, serves to tighten the chain 67. y

In the operation of the machine the plate 1l is properly adjusted and the presser 17 set with reference to the thickness ofthe stock so as to leave between the surface of the feed roll and the operative surface of the presser a space the width of which is less lthan that ofthe stock to be buffed. Power is then vapplied to the counter-shaft therebyr rotating the boiling roll, the striker and the fan at high speed and the feed roll at comparatively low speed. The pieces of stock arev fed 'one by one to the machine. Each piece of stock is gripped between the presser 'and the yielding surface of the feed roll'by being pressed into said yielding surface. The stock is thus firmly held while the b'ufiing roll rotat-ing at high speed buffs said stock.v As the forward end of the piece of stock emerges from between the rolls and approaches the shaft 31 a rapid succession of blows is delivered upon it by the striker 35 so that the forward portion of the stock raised in position to be carried away by the suction apparatus. As the stock continues to be advanced, its forward end presently encounters the inclined perforated guide 37 and is deflected outwardly toward the operator.

I have found the striking or tapping of the free end of the stock very effective as compared with a uniform brushing action. The successive sharp blows effectively raise the dust which normally clings to the bufed surface of the stock and would not belthoroughly removed by the action ofthe usual cylindrical brush. I have found, however, that the desirable effects of both the'striker and an ordinary cylindrical brush may, be secured by forming the striker as illustrated, as asegment of a cylindrical brush and using very stiftl bristles which yield as a whole very slightly if at all.

Although the invention has been set forth in connection with a particular machine it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.

Having thus described my invention, what I claim and desirelto secure by Letter Patent of the United States is 1. A machine of the class described having, in combination, a buiing' roll, means for feeding stock to said roll, and means for viplratmg the stock after it has passed said ro l 2. A machine of the class described having. in combination, a buiing member for acting upon stock, means4 for feeding the stock to said member, and means for removing the dust generated by the buing operation, said last named means" including a movable member for jarring the stock to drawing a current of air' past said memberA and feedlng means, and means for beatlngv the buifed portion of the stock to raise the dust into position to be swept away by said current.l
