MACHINE FOR WASHING PRINTERS FURNITURE.

To all whom t may concern.'

Be it known that I, FREDERICK W. STEINER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Washing Printers Furniture, of which the following is a specification.

My invention relates to improvements in machines for washing printers-furniture.

One of the objects of my invention is to provide a machine that will thoroughly and quickly wash printers furniture, such as slugs, rules, etc., and which will provide a substantially gas tight closure for the very volatile detergent used to cleanse the articles, such as benzin, gasolene or the like, thereby to reduce the danger of ignition and explosion.

Another object of my invention is generally to improve machines of this character,

` to cheapen 'the cost of production; to render them self-draining and to simplify their construction. j

Other and further objects of my invention will be readily understood from the following description when taken in conjunction with the drawings, wherein Figure 1 is a side elevation of the machine withl the top raised and the cylinder in position to be opened, to admit the material to be cleansed. Fig. 2 is a central, vertical section, taken on line 2-2 of Fig.- 1. Fig. 3 is a transverse section taken on line 3 3 of Fig. 1. Fig. 4 is a section taken on line 4 4 of Fig. 1. Fig. 5 is an axial section of a fragment of the drum. Fig. 6 is a sectional detail portion of the body part, and a portion of the top, showing means for holding the top open.

In all the views the same reference characters are employed to indicate similar parts.

The main body part of the structure is composed of fourl substantially vertically disposed angle irons 10, deiiected near their bottom, as at 11, to provide feet and having attached to their sides three fixed preferably sheet metal side walls 12, 13 and 14. Secured to the open side of the structure are two swinging doors 15 and 16 hinged, as at 17, and provided with a latch 18 to hold the doors together when they are closed. A

Specification of Letters Patent.

` 29, for engagement with the shaft.

semi-cylindrical top 19, is hinged to the side wall 13, as at 20, and when down in position ltpoverhes the upper portion of the rotatable drum 21.

'A slotted bar 22 is pivoted to the top, as at 23, and is provided with a slot 24, which includes the pinf25 that projects inwardly from the wall 12 Iof the structure. The bar 24 and the slot are curved laterally near the bottom end, as shown in Fig. 1, so as to engage the pin 25 for retaining the top 19 in ralsed position.

The drum 21 is provided with two heads 26, which are substantial duplicates, and which are securely mounted on the shaft 27, as by means of pins 28--28. Each head is provided with an inwardly projectin hub circumferential wall 30 is secured to the outer periphery of each of the heads 26, and a wood lining 31, is perforated with holes 32 that register with similar holes in the sheet metal wall 30. The wood lining'is placed in the circumferential groove, between the wall 30 and the inner annular flange 33 projecting from the head 26.

A door 34 is adapted to be slid outwardly from the drum to provide an opening for admission of material within the drum. When the drum is in the osition shown in Fig. 1 with the top 10 raised the door 34 may be moved laterally without interference of any of the other portions of the structure.

Bearings 35 are provided in the vertical walls of the body portion of the structure for the ends of the shaft 27 and one end of the shaft 27 is fitted with a geared pinion 36 which meshes with the gear wheel 37 that is rotated by means of a handle 39 to rotate the drum. A protecting housing 40 covers this train of gearing.

A semi-cylindrical tray 41, is normally in the bottom of the body portion of the structure, and when lifted it is adapted to receive the lower portion of the drum 21. Each corner of the tray is provided with a guide comprising a short piece of angle iron 42, adapted to slide within the corner angle irons 10 when the tray is being lifted. Projecting laterally from each side of the tray are studs 43 to which lifting cables 44, on each side of the tray are connected. The

,and is provided with a handle 52, by. means of which(4 the pawl may be lifted from the ratchetw'heel. A spring 53 normally holds the pawl in engagement with the ratchet wheel. When the handle 48 is turned, in clockwise direction, the cables 44 are wound upon the drums -46--46 and the tray 41 is raised until the detergent, contained therein, passes through the perforations `32 made in the cylindrical walls of-the drum, the ratchet wheel and pawl hold the tray in elevated position. Now when the handle 39 is rotated the drum 21 is rotated within the tray 4l and the articles contained in the drum are thus moved yin the liquid detergent and thus the cleansing operation is performed. After the drum 21 has been rotated sufficiently to cleanse the articles the tray 41 may be lowered by pressing upon the handle 52, controlling the pawl 53 so as to release the ratchet wheel 49, when the handle 48 may be turned to the left and permit the tray 41 to descend to its lowermost position. After this has been done the articles contained within the drum 21 will drain and the surplus Huid will fall back into the tray 41.

It is very essential that the doors 15 and 16, of the casing be closed and that the top 19 shall be down to close the open end of the casing, when the drum 21 is being revolved in the detergent contained in the tray 41, and for this purpose I provide an automatic means for closing the door by the movement of the top19. To this end I provide on each side of the top 19 a rod 54, which is pivotally connected to the point 53 of the top, which extends any convenient distance down the side walls of the casing, to the lower end 55 of which is cpnnectedla cable 56, that passes around a guide pulley 57 and is connected by its free end to a bracket 58` projecting from the respective door. A spring 59, which is .connected to one of the legs 11 and to the bracket 58, normally holds the respective door in closed position. When the top is' raised,^the cables 56-56 are raised, which pulls upon the brackets 5 8--58 against the operation ofthe springs 59-59 and causes the doors to open. When the top is. lowered the springs 59-59 will be free to operate the respective doors and therefore the doors Will thereby be closed;

by the eii'ect of the springs the drum 21 will be included in a perfectly gas tight nclosure, when the top is lowered, while the gas is evolved by agitation of the detergent during the process of washing.

To drain the tray of the detergent that is no longer useful `I provide a stop cock 60, fixed to the lower part of the tray and a lip 61, that extends through the casing 12 and under the stop cock so that when the cock is ened the fluid from the interior of the tray will be-received by the lip 61 from which it may How into a proper receptacle.V To closethe opening in the lip 61, I provide a shutter, or door 62, pivoted as at 63, and provided with a lifting knob 64. When .the device is not in operation the volatile detergent is protected from danger of fire and loss by evaporation.

1 have 'described a specific structure to disclose my invention but it must be understood that departure from such embodiment may be made in the configuration and disposition of the parts within the scope of the appended claims.

Having described my invention, what I claim is 1. A machine of the character described comprising a perforate drum; aI closed 'casing structure, upon which the drum is mounted; a semi-cylindrical tray for containing a detergent mounted within said structure below the drum and means for relatively moving said tray and drum to s include the lower portion of the drum within the tray.

2.

3. A machine of the character described comprising a three wall structurefopen at one Side; two doors hinged on opposite sides of the opening for closing said opening; a cover forclosing the open top end of the structure; a perforate drum mounted in lsaid open end; a tray for containing a detergentl a drum comprising end disks and a circurnferentially extending perforate sheet metal wall; a Ylining of softer material for said Wall having perforations registering with hand in the presence of two subscribing Witthose of the sheet metal Wall; a door for Said nesses. drum comprising a portion of the Wall of FREDERICK W. STEINER. said structure slidable axially to open same; 5 a shaft upon which said drum is ladapted to In the presence o4 be rotated and means to rotate said drum. FORE BAIN,

In testimony whereof I hereunto set my MARY F. ALLEN.
