JOHN F. SEIBERLING, OF AKRON, OHIO.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 470,214, dated March 8, 1892.

Application iiled July 2, 1888. Serial No. 278,766. (No model.) I

T @ZZ whom it may concern:

Be it known that I, J o HN F. SEIBERLING, of

l Akron, county of Summit, and State of Ohio,

ksheet of paper or other material.

My invention relates more particularly to' the construction and arrangement of the machine-frame and type-levers; to the means for covering the inking ribbon or pad when not in use and thereby protecting the same from injury resulting from the action of the air thereon, evaporation of the ink, accu mulaton of dust and dirt, or other causes; also, to the means for locking the type-levers or their actuating mechanism while the ink ribbon or 'forms the ink-pad holder.

pad is covered, and in certain other features of construction and arrangementhereinafter set forth.

In the accompanying drawings, Figure l represents a section from front to rear of a type-writing machine embodying myimprovements. Fig. la is an enlarged sectional View showing the manner of adjusting the inking device. Fig. 2 is a side elevation of the inkpad holder. Fig. 3 is a plan View of the parts shown in Fig. l. Fig. 4e is a sectional view similar to Fig. l, showing a modified .form of type-actuating mechanism and means for covering the ink-pad; and Fig. 5 is a plan view of the same.

Arepresenls the base of a type-writing machine, upon which all the other parts are mounted.

B B indicate the uprights or standards, upon which a ring or annular frame O is secured by screws or in any usual manner.

D represents an annular piece or ring which Said ring surrounds, snugly, the annular frame C, and is adjustably connected therewith by means of screws c, passing through inclined slots d, Fig. 2. The pad-holder is of annular form in cross-section, or, more accurately speaking, has two vertical portions D and D2 connected by a horizontal portion of flange D, as best illustrated in Fig. 1n, thus forming a receptacle for an inking-pad E. The latter is annular in form, is composed of any material adapted to the purpose of receiving and holding ink, and when in position for use occupies a place just above the plane of the annular frame O, forapurpose that will appear. vWhen the type-writer is not in use, the pad-holder is lowered by rotating the same partially around the. frame O, when the inclined grooves act upon the pins or screws c, the effect being to depress the pad-holder and cause the inking'- pad to take up a position in horizontal line with said frame O, as shown in dotted lines, Figs. l and l, against which it rests in close contact or proximity, the object being apparent- Viz., to protectsaid inking-pad from injury of any kind, whether from dust, dirt, evaporation of the ink, or other cause. Another object in adjusting the ink-pad is to bring a new surface thereof into position for the types to get their supply of ink from and also to prevent too much wear in one spot,'caused by said types striking and resting continuallyin one place on the ink-pad. Knobs d may be employed for enabling the operator to adjust the pad-holder.

For the purpose of securing the inking-pad in place, and for the additional purpose of protecting the types and type-levers from injury when the machine is not in use,a ring or cappiece F is slipped over the pad-holder D, as shown, being secured by fitting tightly or snugly around the portion D2 of theA padholder D, or it may be secured in any usual or preferred manner. The cap-piece F is also angular in cross-section, its horizontal portion overlying the inking-pad and its upper vertical portion being in the same vertical plane with the inner face of the inking-pad. Vhen the pad-holder is lowered, as described above, the inner portion of the cap F will occupy the position lately occupied by the inking-pad,as shown in dotted lines in Fig. la. ing-pad when in use is located in such position that the types will rest against it, accordingly when the pad-holder is lowered the upper portion of the cap F will occupy a similar relation to the types and prevent injury to the same.

G represents a central standard or post, and

As the inky IOO G an upright or support adjustable vertically in a socket in said standard,being secured at the desired adjustment by a screw g. Said support G is provided at its upper end with a hub and radiating arms g2, which uphold a ring H, preferably rectangular in cross-sec tion, as shown inl Fig. l. Upon this ring a number of guid e-plates I are secured by means ot foot flanges and screws, as shown, or in other suitable manner. Said guide-plates I are each provided with a guide-slot I and vertical guide wall or projection tor a purpose that will hereinafter appear.

.I .l indicate the type-levers or levers which carry the types used in making the impressions. At their upper or type ends these les vers are by preference made solid; but at or near their center they are bifurcated ort'ormed each with two similar parallel arms, which embrace the ends of links or arms K. The latter extend from said connection outward to beyond the annular frame C, where they are pivoted to lugs of an annular frame I., sur rounding the standards l and attached thereto by means of brackets M, as shown. rlhe type-levers are also provided each with a pin or rollerj, which is adapted to travel in the slot I ot the guide-plate I and against the vertical projection 'i of said guide-plate for assisting in the proper guidance of the typelever in its movements. 3y this arrangement it will be seen that the type-levers have no fixed pivots, but that such pivots change or move in guide-slots and constitute whatI term iioating type-levers. Supplelnental arms K are also employed, pivoted at their outer ends to lugs of frame L and extending inwardly in a plane substantially parallel with arms K, referred to. rlhe inner ends of these levers form stops, against which projectionsjzof the type-levers .I strike and rest, when operated as hereinatter described, for limiting the movement of the type-lever and directing its course in a vertical line, so that the type may strike squarely against the paper and produce a clean sharp impression. The arms K and K are connected by links 7c. Pendent links or rods N connect the arms K with a series of key-levers O of diiterent lengths, each suitable as to length to the location of the 'link or rod with which it is connected, and

said key-levers are pivoted at suitable points in the tulcrum-posts P on the base A of the machine. The levers O all extend toward the front of the machine, as shown in Figs. l and 4, (left hand), where they are provided with upwardly-extending rods R, to which the operating-keys S of the type-writer are secured.

T indicates an inclined table, which is provided with perforations, through which the rods R pass-and are steadied in their movements, the table being secured by its connection with the outer ring L at its upper end and with a vertical plate or support T at its lower end.

U represents the platen or roller which carries the paper to receive the impressions of the types.

In Fig. l the typelevers are shown in both the operative and inoperative positions, with the operating devices and links in corresponding positions. Vheu a key is depressed, the rod R depresses the end of the lever O, to which it is connected. The opposite end of said lever is thus elevated and operates through the medium of link or rod Nte rock the arm II upward on its pivot. The inner end of arm K is thus caused to act upon and throw up the type-lever J until the type ,y thereon strikes the paper and produces an impression. The key being released, a suitable spring O elevates the outer end of lever O, thus returning the type-lever and its connections to their position of. rest, the types j lying against or in contact with the inkingpad E, as shown.

A modified form of guide-plate I is shown in Fig. Lfl, in which said plateis provided with an L-shaped slot I. Said slot is inclosed, as shown,which enables me to dispense withthe supplemental arm II', as the pin .7", not being able to escape from the slotI, the latter acts in place of arm K to limit the movement of the type-lever and guide the same in a vertical path. Now when the type-writer is not in use the ink-pad holder is adjusted to its lower position, as above described, or until the ink-pad E occupies the position shown in dotted lines in Fig. l, The cap F is thus brought down and protects the types from injury. 3y the adjustment of the pad-holder to such position the lower edge or face di thereof will descend to the position indicated in dotted lines in Figs. l and l, which will prevent the arms K from rising, thus locking the type-actuating mechanism in the position of rest. It will thus be seen that by the adjustment of the ink-pad holder the ink-pad and type are covered and protected and the type-actuating mechanism locked or held inoperative until the pad-holder is moved back to its former position. y

In Figs. 4 and 5 a modified form of devices for covering the inking-pad is illustrated. The movable pad-holder in this case is dispensed with and the annular frame C is recessed or cut out to receive the annular inking-pad E. rlhe inking-pad being thus stationary, the upper vertical portion of the cap F is also dispensed with. The outer ring I. may also be dispensed with and the arms K pivoted directly to the annular frame C, as shown in Fig. 4.

The device for covering the inking-pad is composed of an annular plate or cylinder V, extending around within the annular frame C and fitting snugly against the ink-pad E, as shown. Said covering-plate V is provided with slots n, through which are inserted pins or screws c', thus allowing said plate to be adjusted up and down for covering or uncoverin g the in kin g-pad. llo provide mechanism TOO IIO

for adjusting said plate V, links w are employed, attached at one end to said plate and operated at the other end by crank-arms w on rock-shafts W.

X indicates a bar or plate, which extends transversely across and near the front ot the machine and underlies the key-levers O, as shown in Fig. 4. Said bar connects the crankshafts WV through the cranksa: 0c, so that when one shaft W is operated bya handle or crank Y for that purpose the other shaft W' will also be caused to operate for simultaneously operating the links w and adjusting the plate V. The cranks w anda: are so arranged that when the plateVis elevated to cover the inkpad the bar or plate Xwill also be raised to a position directly beneath the key-levers O, thus locking the type-actuating mechanism in the position of rest simultaneously with the covering of the ink-pad, both of whichresults are accomplished by only one act on the part of the operator-viz., operating crank Y.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is-
