Claims.

This invention relates to a machine for cleaning the matrices of type settingmachines and of the kind wherein the matrices are made to travel past rotary brushes which efiect the cleaning by 5 means of a suitable cleaning fluid, .for instance benzine or the like.

The object of the invention is tobbtain a machine of this kind which is of simple construction, easy to supervise, and reliablein its operation, and the invention consists essentially in the provision of a pair of parallelfeed screws to which the matrices are delivered one by one from .a pile and from which they are led between emllcss travelling drying bands to an assembler, rotary brushes being provided some of which act on the pile for cleaning the edges of the matrices, while others operate over a guideway between the feed screws for cleaning the faces thereof, and means being provided for reversing the matrices on the guideway so as to present first one and then the other face to the brushes.

and.

Fig. 9 is a section on the line IX-IX of Fig. 8.

The devicecomprises a table top 2 which is supported by legs l and which carries in suitable bearings two parallel, horizontal feed screws 3| and 32 adapted to receive the matrices between them and to move said matrices along a guideway 39 by the engagement of the screw threads with the ears of the matrices. Each screw is provided with two threads 35 and 36 one of which is narrower than the other, and the threads are out and pitched so that wide spaces are provided for the reception of the long ears 31 of the matrices, and narrow spaces for the reception of the short ears 38 thereof. One screw has right hand and the other left hand screw thread, and the screws are rotated by intermeshing gears 33 in opposite directions and towards the matrices so as to urge the latter against the guideway.

Rotary brushes 4? and 48, driven by means of belt pulleys 49 and 50, are arranged over the guideway .359. for cleaning the faces of the matrices-means being provided for reversing the matrices on the *guideway so that first one and then the other face of each matrix will :be exposed 5 to the brushes. This reversal is eifiected through the medium .of .a forked .arm M which is pivotally supported at 42 between supporting brackets 43 some distance above the .guideway and which bears with its free, forkedandhooked end against 10 the guideway. The latter is termed with slots 416 in which the hooks M .of the arm normally engage. On the hooks being engaged bythe leading end members 0f.:a travelling matrix; the arm 44 will be turned about its pivots -42, as shown by dotted lines in Fig. 5., the matrix being at the same time turned over in the vertical, longitudinalplane of the :guideway and deposited on the latter with the opposite .face in position to be cleaned by .the next brush. Inprder to. facilitate .the reversal of the matrices, the space between the screw threads is widened tor about 34 of the circumference of the screw at the point where the reversal takes place.

The matrices are delivered *on to the 'guideway 39 from a pile located in a magazine 6.. The latterhas a vertical guide member .l. which isribbed in conformity with the notches in the recessed ends of the matrices. The pile is supported at the bottom of the magazine by spaced ledges Ill and ll on which the lowermost matrix :rests by means of its ears, :as shown in Fig. 9, and cfi which :it is slid on tothe guideway 39.. This is effected by means :of a reciprocating slide l4 and aapawl l2 which latter :is pivoted atxlt to the slide and .supportedhy :a spring :li5 in position .to en gage and eject the lowermost matrix from the pile on the slide being reciprocated. A plate 8 arranged in a central position in the magazine and in a vertical plane, serves as a detent for the matrix next above the one to be ejected. The free end of the plate is reduced as shown at 8a. and adapted to engage in the groove 9 in the ejected matrix for guiding the latter until it is slid off the ledges. The pawl I2 is provided with laterally projecting studs I6 adapted to engage the bevelled ends of bevelled guide rails ll, formed by the lower edges of the walls of the magazine 6, for depressing the pawl and preventing the latter from coming into contact with any but the lowermost matrix of the pile. There is also a guide member 29 which is pivoted at 28 to the back of the magazine and arranged so as to be deflected by the ejected matrices in opposition to a spring 30. In its turn the guide member der presses the matrix and ensures a correct positioning thereof between the feed screws.

The slide I4 is reciprocated by means of an arm I 9 which is rocked about a centre I8 through the medium of a rod 20 which bears under the pressure of a spring 20 against a cam 2|. The latter is driven by gears 34 from one of the feed screws, so that the movement of the latter will be synchronized with the matrix ejecting slide I4.

The magazine 6 is open so that the edges of the matrices can be cleaned while the matrices pass through the magazine. This cleaning is ef-' fected by means of brushes 22 arranged one at each side of the magazine. The brushes are carried by slides 23 in a support 24 andare adjustable by means of screw spindles '25." A similar arrangement is employed, as shown in Fig. l, I for adjusting the brushes 4? and 48 relative to the guideway 39. The brushes 22 are rotated through the medium of conical gears 26 and a belt pulley 21.

The cleaning brushes are fed with benzine, for instance by hand, and a subsequent wiping and drying of the matrices is therefore required. This wiping and drying process is eifected through the medium of a pair of co-operating, endless, travelling bands 55 and 56, one guided on rollers and 52 and the other, on rollers 53 and 54, all arranged under the table top-2. The feed screws deliver the matrices into a chute 45 whence they are led through a channel 46 into position for being received between the drying bands. The lower band moves over a rigid supporting surface 51, and the upper band is pressed against the lower band by a plate 58 which is suspended from links 59 and preferably controlled by a spring 59, so that the matrices will be clamped between the bands. The latter are moved at different speeds, so that a rubbing and wiping action will take place whereby the matrices will be delivered from the bands in dry and perfectly clean condition. An electric heating element 6| may be employed for heating either the plate 58 or the supporting surface 57. A tensioning roller 62 may be provided for the lower band 56, and a press roller 5la may be arranged to bear against the upper roller 5| in order to ensure a uniform movement.

The drying bands deliver the cleaned matrices through a chute. 63 into a container 66 wherein they are assembled. The container is provided with a plurality of compartments 65 all of which can, by a shifting of the container, be brought into receiving position. I In the arrangement shown, the container is supported by means of rollers on inclined rails 12 and has a tendency to move down the track thus produced. A catch lever 69, which is controlled by a spring 10, is

adapted to engage in a rack 'H in the container for arresting the latter with any one of the compartments in receiving position. The matrices are packed endwise in the container by means of a star wheel 64, each compartment having a slidable partition 6'! which recedes in proportion as the packing progresses. As the partition reaches the end of the compartment, it strikes against and rocks the lever 69, first to release the container which therefore shifts into the next position wherein it is re-arrested by the catch. The action is repeated for each compartment. The par "tition of the last compartment may be adapted to operate an electric switch for stopping the machine when the compartment is full.

I claim:
