WILLIAM P. QUENTELL, OF NEW YORK, N. Y.

TYPE-WRITING MACH IN E.

SPECIFICATION forming part of Letters Patent N 0. 624,865, dated May 9, 1899.

Application filed July 15,1898.

To all whom it may concern;

Be it known that 1, WILLIAM P. QUENTELL, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification.

By means of this invention a type-writing machine can be obtained which is cheap and simple of construction, as set forth in the following specification and claims and illus. trated in the annexed drawings, in which- Figure 1 is aplan view of the machine with parts broken. Fig. 2 is a sectional side elevation of Fig. 1. Fig. 2 on a larger scale. Fig. 4 is a plan View showing the type-segment as having been moved. Fig. 5 is a detail view of part of a key-lever. Fig. 6 is a detail view of part of the cross-bar which actuates the hammer-actuating lever and the spacing mechanism,

On a suitable base 1 is a track or way 2, Fig. 3, for the paper-carriage 3, having feedrollers 4 and 5f0r the sheet or paper coming from the storage 6. The sheet passing back of type wheel or segment 7 receives a print when driven against the type by the stroke of hammer 8, Fig. 2, having its fulcrum or support at 9. A stud 10 on the hammer is engaged by arm 11 of lever 11 12, fulcrumed at 13 and having cross-bar 14. The key-levers 15, fulcrumed at 16, Fig. 3, engage or rest on the cross-bar 14 and are provided with finger buttons or keys 17, as customary. When a key-lever is depressed, it acts on cross-bar -14 to swing lever 12 11 and cause arm 11 to swing the hammer 8 so as to make a stroke or print. This bar 14, as seen in Fig. 6, has a cut or depression 13, located centrally or at the spacing-key 19, so that the latter is depressed or actuated without moving bar 14 or hammer 8. The bar 14 can be steadied by arms 20, Fig. 4, swinging on fulcrum 13 and forming, with bar 14, a bail-like structure.

' The type-segment 7, with its shaft 21, is rotated or swung by the depression of a key, as presently explained. A stop-arm 22 is fixed on or extends from this shaft. The keys have stop-pieces which, as seen in Fig. 5, comprise each a stop portion 23 and acut or passage portion 24. The cuts or recesses 24 allow the type stop-arm 22 to pass or swing by the re- Fig. 3 is a view similar to Serial No. 686,031. (No model.)

spective keys when the latter are at rest; but

.levers or secured or jointed thereto in suitable way. The stop-pieces are shown extending upwardly from the key-levers, and a guide or plate 25, having ways or perforations 26, is provided for the stop-pieces. This guide 25 is applied above the levers 15, and the type stop-arm 22 is made to travel between this plate 25 and the key-levers.

In Fig. 3 is shown in full lines a key 15,with stop-piece 23, at rest or in normal position, the passage or receding portion 24 of the stoppiece being in position for arm 22 to pass or travel by. In broken lines is shown a key 15 depressed, the corresponding stop-piece having brought its stop portion or full upper part 23 into the path of arm 22 to arrest the latter.

The type-segment 7 is loose on shaft 21', but is caused to rotate therewith by arm 27, Fig. 3, engaging the type-segment and extending from shoulder or transmissionpiece 28 Fig. 4, fixed to the shaft. The shaft is rotated one way or another,as the respective oneof the oppositely-located shoulders of piece 28 is actuated by its lever-arm 29. These levers 29 30 are fulcrumed at 31 and are each connected at 32, as by a pin or stud, to alever 33, fulcrumed at 34. Each lever 33 is provided with what may be called a cross-piece 35. As a key 15 at one side or another of the machine is actuated its respective lever 33 is actuated, together with the respective lever 29, so that the type-shaft is swung one'way or another.

The cross-bars 35, it is noticed, do not extend at right angles to their respective key sets; but each bar is inclined or arranged so 35 which is fartherfrom fulcrum-strip 16, the

degree of play or depression of the various keys being the same or practically so, such depression of the last-named key will cause bar 35, with lever 33 and type-segment 7, to be actuated to a different extent and another type to be brought to the printing-point. As the various keys are thus depressed and engage different points along one or another of the inclines 35 the type relating to the successively-actuated keys are brought to the printing-point as required. As a key 15 ac tuates or depresses bar 14 the latter actuates the free or end portion 36, Fig. 4, of an arm 37, extending from rock-shaft 3S, connecting by arm 39 and link 40 with arm 41 of feeddog 42, Fig. 3, engaging rack 43 of carriage 3. As the dog 42 is thus oscillated or actuated under the influence of lever 37 38 39 and of returning-spring 44, the carriage is fed, as known.

At 45, Fig. 4, is shown fulcrumed an arm.

46, the free or end part 47 of which engages arm 37 at some distance from its free end 36 or near to fulcrum 38. The spacer 19 engages arm 46, and as the latter is swung or depressed by the spacer the parts 37 38 39, with dog 42, are' actuated.

The type-segment may have different type rows brought into action by case or shift keys 48; but as such arrangements are known no description thereof is here required.

The hammer-actuating lever 11 12, it is found, is practically arranged so that thearm 11 directly or positively engages the hammer and does not carry the hammer all the way to the printing-point; but said arm stopping short before the hammer reaches such point the latter, swinging loosely on pivot 9, will by its momentum continue to move until the print is made. 7

The type-segment shaft 21, the keys 15, and the lever mechanism 29 3O 33 foractuating the shaft are all brought to a stop when the arm 22 strikes the actuated or depressed key or stop-piece. This stop-arm. 22, mounted directly on the shaft 21, thus positions the segment and also positively stops or arrests the lever mechanism 29 3O 33, while the hammer, loosely connected to or engaged by the lever 11, will continue its motion by its momentum after the stoppage of the lever mechanism, so as to give the printing stroke.

By having the stop-pieces 23 extend upwardly and the arm 22 located above keys 15 the arm 22 is in reach of the operator and allows the type-Wheel to be turned or held to one side or another-for example, when brushing or cleaning the type. To engage the upwardlyextended pieces 23, the guide 25 is located above the key-levers 15.

found to permit a certain degree of looseness which avoids the necessity of any drivingspring for the hammer, and such structure is strong and durable and not liable to weaken, as might occur where a spring is employed, especially if such spring has to be kept permanently under more or less tension. As the hammer and lever 11 are both rigid or nonyielding and as the hammer rests positively or non-yieldingly on the lever 11, the full force of the upward throw of the lever is imparted directly to the hammer. The lever-arm 11, as seen, is also of considerable length, and the point 10, where the arm 11 engages hammer 8, is located back of the carriage. This arm 11, because of its length, is capable of a considerable sweep or swing to readily impart the required force to the hammer for giving an effective printing stroke. 5
