TYPE-CLEANING DEVICE FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed February 9, 1906. Serial No- 300,285.

To all whom it may concern:

Be it known that I, DANIEL Bnroes, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Cleaning Devices for Type-Writers, of which the following is a specification.

My invention relates to type cleaning devices for typewriting machines and has for its object to provide a simple and efficient device of the character described and which may be readily attached to and detached from a typewriting machine.

To the above and other ends, the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a typewriting machine showing my invention adapted thereto, parts of the machine being omitted. Fig. 2 is an enlarged sectional view of the type cleaning device and a part of the frame of the machine, the section being taken transverse of the machine, and the parts being shown in inoperative position. Fig. 3 is an enlarged front elevation of the type cleaning device, the parts being shown in operative position. Fig. 4 is an enlarged top plan view of a part hereinafter called the brush head, the support thereof being shown in transverse section. Fig. 5 is an enlarged detail view in horizontal section showing the connection between the brush frame and the actuating lever therefor.

Referring more especially to Fig. 1, 1 indicates the side portions of the base frame, said side portions being connected by front and back transverse portions 2. Corner posts 3 rise from the base and support a top plate 4 on which is secured a circularly disposed set of type bar hangers 5 pivoted'in which at 6 are type bars 7, said type bars being connected by links 8 with key lovers 9 fulcrumed at 10 in the rear of the base, and each provided with a restoring spring 11. The normal positions of the type bars and their actuating devices are shown in full lines in Fig; 1. The type bars carry type blocks 12 at their free ends and normally lie against a type rest 13 fixed below the top plate of the machine. Said type bars are adapted, when their associate key levers are actuated, to be swung upward, as indicated by the dotted lines in Fig. 1, to cooperate with the bottom of a cylindrical platen 14 diagrammatically illustrated.

Referring now to the type cleaning attachment, I

' provide a supporting bracket comprising two parts, a

' latter being perforated to receive a pivot rod 18 by which the part 15 is connected with the other part 19 of I the bracket (Figs. 1, 2 and 3) which is likewise preferably made of sheet metal. Said part 19 is vertically disposed between the ears 17 of the part 15 and is broadened out at its lower end, terminating in a hook portion 20 and being provided at the sides with stiffening flanges 21. The part 15 of the bracket is provided with a boss 22, said boss being formed with a threaded opening which receives a thumb screw 23 for securing the supporting bracket in place. The end of the screw 23 is adapted to engage with a spring-plate 24 which is formed with a shoulder 24 and secured to the under side of the part 15 of the bracket by headed screws 25. The spring plate serves both as a protector and as a lock, in a manner presently to be described. Near its inner or free end the part 15 is provided with a thread ed opening which receives the lower threaded end 26 of a vertically disposed supporting rod 27, the thread ed portion 26 beingof reduced diameter and forming a shoulder 28 with the body portion of the rod, said rod being screwed down until the shoulder abuts against the top of the part 15. A locking nut 29 engages the threaded portion 26 and is screwed up against the under side of the part 1.5, thereby serving to secure the rod 27 fixedly to said'part 15. The sides of the supporting rod 27 are flattened, as indicated at 30, shoulders 31 being formed on the rod 27 where the flattened portions 30 terminate, said shoulders serving as stops in a manner presently to be described. Loosely and slidably mounted on the support or rod 27 is a sleeve 32, said sleeve being squared at its upper part as indicated at 33, the squared portion forming, at its junction with the body portion of the sleeve, a shoulder 34. The upper portion of the squared part 33 is rounded and externally threaded as indicated at 35. The squared portion 33 receives a conical brush head 36 which is formed with a square opening 37, said square opening cooperating with the squared portion 33 of the sleeve 32. The head 36 is provided with bristles, some extending downwardly and some inclined downwardly and laterally, said bristles forming a downwardly disposed conical cleaning brush 38, which surrounds the sleeve 32 below the brush head 36. A thumb nut 39 cooperates with the threaded portion 35 of the sleeve to clamp the brush head against the shoulder 34, thereby maintaining the brush in fixed relation with the sleeve. Below the brush the sleeve 32 is provided with two oppositely disposed horizontal slots 40, said slots being cut in sulficiently deep to penetrate the bore of the sleeve and expose the supporting rod 27 within said sleeve as indicated in Fig. 3. Secured to the part 15 by headed screws 41 is a small substantially U-shaped supporting bracket 42 preferably made of sheet metal and pro vidcd with vertically disposed ears 43, said ears receivin g a pivot rod 44. The rod 44 serves as a fulcrum for a sheet metal actuating lever 45, said lever being provided at its outer end with a finger piece 46 and having at each side stiffening flanges 47, each flange being shaped to form a nose 48 below the fulcrum 44. The inner end of the lever 45 is bifurcated, the arms 49 of the bifurcation entering the oppositely disposed slots 40 in the brush sleeve 32 and thereby loosely connecting the sleeve with the lever. A flat locking spring 50 is secured to the top of the part 15 by means of the screws 25 and the free end of said locking spring is adapted to cooperate with the noses 48 on the actuating lever 45.

Referring now to the mode of attaching and operating my improved type cleaning device, it will be understood that said device is attached to one of the side portions 1 of the base of the machine, the part 19 of the supporting bracket being swung about its pivot 17 until the hook portion 20 engages the bottom edge of the side portion 1. The thumb screw 23 is then screwed down tight to clamp the two-part bracket in place, the spring plate 24 being interposed between the end of the screw and the top flange 1 of the side portion 1, and thereby preventing said side portion from being marred by said screw. The angular shoulder 24* of the spring plate abuts against the top flange 1 and prevents the bracket from being accidentally displaced laterally outward. Furthermore the spring plate tends to draw the hook 20 up against the part 1 to lock the bracket in place. When properly secured in place the part 15 of the supporting bracket extends inwardly towards the middle of the machine above the key levers 9, passing between two of the links 8 and being so disposed as not to interfere with any of the working parts of the machine. It will be noted that the two parts 15 and 19 of the supporting bracket form a knuckle joint, the top of the part 19 abutting against the under side of the outer end of the part 15 (Fig. 2). This abutting engagement of the parts is at the opposite side of the pivot 18 from the screw 23, so that when said screw is tightened the bracket as a whole is elevated, drawing the hook 20 up tight against the bottom of the side portion 1. The castings of machine frames are found in practice to vary in dimensions; but my construction is such that though the depth of the side portion may vary considerably, yet the two part brackets may readily be attached thereto. ,The machine illustrated is the Remington and my attachment is particularly adapted to the Nos. 6, 7, 8 and 9 Remington, but, of course, may be constructed to be applied to other makes of machines. The supporting rod 27 is secured on the part 15 of the bracket in such position that when said bracket has been secured in place as described, said supporting arm will be vertically disposed about centrally of the type basket. The inoperative position of the parts is shown in Fig. 2 and in full lines in Fig. 1. In this position the bottom of the sleeve 32 is in contact with the top of the part 15, the conical brush 38 being lowered out of the paths of the type blocks 12, as will be understood from a consideration of Fig. 1. When it is desired to clean the types, the finger portion 46 of the lever 45 is depressed, thereby raising the inner arm of said lever and causing the arms 49 of the fork or bifurcation at the end of said lever to raise the sleeve 32 and the brush sure exerted by the operator, but as soon as the spring contact passes from one side of the noses to the other, the pressure of said spring will be reversed and it will tend thereafter to lift the type brush. The upward movement of the brush continues until the inner edges of the arms 49 of the actuating lever engage with the shoulders 31 on the supporting rod 27, thereby preventing further movement upward. The brush will be stopped in the position indicated in full lines in Fig. 3 and in dotted lines in Fig. 1. If now the several key levers be depressed, their associate type bars will be swung upwardly from normal position until the type blocks are arrested by the cleaning brush 38. As will be understood from a consideration of Fig. 1, the bristles of the brush are arranged substantially perpendicular to the face of the types so that the ends of said bristles may readily penetrate the depressions in the types and clean them out. The arms 49 of the lever 45 closely embrace the slotted portion of the sleeve 32, as will be understood from a consideration of Figs. 1 and 5, so that said sleeve is held from rotation and consequently the type brush 38 is prevented from rotating. This construction provides a non-rotating brush, the bristles of which are presented squarely to the types so as to obtain the most advantageous cleaning effect from said bristles. While I prefer to employ a non-rotating brush, it is to be understood that some of the constructive features of my invention are not restricted to non-rotating brushes.

When it is desired to restore the parts to inoperative position, the operator presses upwardagainst the under side of the finger portion 46 of the lever 45, the locking spring 50 acting against the pressure exerted until the dead center is again crossed, after which it will assist in lowering the brush until the end of the sleeve 32 again contacts with the arm 15 of the supporting bracket.

Various changes may be effected without departing from the spirit and scope of my invention.
