' Application filed January 3, 19101. Serial No. 536,059.

assembled in an assemblerand justified by,

space-bands, and are then in position to receive fluid in the casting mechamsm. Dur-- ing the casting operationa small deposit of type-metal adheres to the space-bands at the casting point, and gradually accumulatin by repeated use, in time forms noticeab e and destructive lumps, on the face of the space-band. At present it is compulsory to clean, by han each space bandnot less than once a shift, that is, every eight hours, and ifit isnot done, the'lumps of metal adhering to the space-band will crush in the walls of the matrices by the closing 1 an vabraslxe or each tune 1t 18 alterations whatsoever being made the of the vise inthe machine. a

At present, space-bands are daily scoured by rubbing them by hand on a pad or block containing a polishing paste or the like to remove the small deposits of type-metal adhering, and it is to obviate this slow, laborious, time-consuming requirement that I provide a device so disposedin the machine that each space-band is automatically given polishing contact on its side released from thespace-band x means, either as a linotype machines, the automatic scouring or wiping of the space-bands each part of, orattachable to,

lug means may be employed without any linotype machine.

The

the construction and combination of parts as hereinafter more fully described and h claimed, having reference to the accompany ingdrawings, mwhitah- Figure *1, is a perspective of the spacebandbox and device. .Fig. 2 is a perspective of the scouring-device; Fig. 3 is a sectional "detail of the space-band It is an object of myinvention' to provide.

Thus, havmg for its function, 1

time they are released from the space-band box, and which wipnvention consists of the parts and ehute. Fig. 4; is

represents a space-band, and B the space-band box.

My invention comprehends the employment of a removable, renewable member, as 2, ofsuitable material and design adapted to'be secured at any place on the machine Fig. 5 is a perinost effective to be positively encountered by each space-band as it traverses its regular circuit, and I have shown it as secured to the space-band chute 3-, leading from the box-B. The member 2 may he formed with a flat bracket extension 4 perforated at 5 to receive a screw by which it is secured to the chute 3, and has a spring leaf 6 folded forwardly and downwardlyso as to partially fill the channel of the chute, 3. Preferably the member 2 is formed of springy material and the leaf 6 may be roughened or corrugated to have an. abrasive surface, or may be covered with a. flexible strip saturated or coated with a polishing material and laced through perforations 8.

In Fig. 5, graphically shown. at -9 on one face of the space-band A, is an accumulation of type-metal, which, when the space-bands and matrices C are assembled, always lines up evenly with the intaglios 10 in the several matrices. -The int'aglios 10' form very thin walls 11 at the casting point, and when thevise'closes, the protuberances 9 clinging tothe space3ba-nds crush in the walls 11.

The operation and effect, then, of this iii-- vent'ion is to so dispose and construct the member 2 that as each space-band falls through the'chute 3, the spring leaf ,6 will wipe, with a polishing effect, the deleterious type-metal from the face-ofthe space-band.

not only is this detrimental accumuclean and polished automatically. While the direct effect of the operation is upon the space-bandsthemselves, there is also indirect efi'ect on the general appearance and life of a font of matrices, for after a matrix has been crushed it produces'a distorted, spotted type-bar.

The essential feature of'the invention is t e provision of a brushing or wiping device operative'upon the face of a space-band, and this may be constructed rated part of the machine, ormay be used as an attachment to the many machinesnow used.

ationprevented, but the space-band'is kept- Having thus describedmy inventiomwhat as an incorpo I I claim and desire to secure by Letters Patent 1s 1. A space band cleansing device comprising a resilient plate having one end re1nov-- ably secured to a stationary member and having the opposite free portion resilient and projecting into the path of space bands, and an abrasive material separably held upon said resilient portion.

2. In a linotype machine, a cleansing device projected into the path of space bands and comprising aplate having a flat bracket extension at one end by which it is removably attached to the machine, said plate having a spring leaf folded forwardly and downwardly and partially filling the channel through which the space bands pass, and

an abrasive niaterialcarried on said spring leaf.

In a linotype machine, a stationary wiper, removably secured to the machine, having a spring leaf member folded forwardly and downwardly so as to partially fill the channel through which, the space bands pass, whereby it intercepts one side of a spaceba-nd, and a removable, renewable abrasive material carried by said spring leaf.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
