Specification of Letters aten Patented Aug. 2? 1912.

Application filed April 14, .1911. Serial No. 621,108.

To all whom 2'25 may concern:

Be it known that 1,. MAX PFATJ, a citizen of Saxony, Germany, residing at Woodstock, in the county of Mclilenry and State of Illinois, have invented certain new and useful ln-iprovements in Type-Forming Machines, of which the following is a specification- The present invention relates toa machine utilized for forming characters upon type, and the class of type upon which it is more especially designed to form characters is that class used in connection with typewriting machines.

One object of the present invention is to provide a form of connection between the swinging heads.

A further object of the invention is to provide means for locking the type carrier forming a portion of one of the heads to the body portion of said head, and to provide means for throwing the locking means out of operative position, which will also operate mechanism for ejectingthe type from the head.

The invention further relates to the featurcs of construction and to the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a view showing two heads of the style employed with section being taken on line 33 of Fig. 2;

Fig. 4., a detail plan view, partly in section, showing the method employed in the present invention for connecting the heads together; Fig. 5, a detail of one of the heads with the cover plate therefor removed; Fig. 6, a detail plan view, partly in section, said section being taken on line 6-6 of Fig. 3; Fig. 7, a detail. showing one of the flanged plates employed in the connection between the heads; and Fig. 8, a plan view of the member which carries the ejecting pins.

In mechanism of the class to which the present invention relates, it is customary to utilize opposed oscillating heads, one of 1 which carries a blank upon which the type is formed; and the characters are formed 7 upon the type blank by a rolling action of the matrix against a surface of the blank. Only one of these heads is power driven, and, of course, there must be some connect-io-n provided between the heads so that they will oscillate in unison. Otherwise, j there would be a misalinement between the matrix and the type blank and an imperfect type would result. It has been customary, so far as I am aware, to employ a gear connection between these two oscillating heads. This has been found to be objec' tionable because of the fact that the gear teeth will become worn after a relatively 1 short period of usage, and hence a slippage mation of the type. It is one of the primary ob ects of the present invention to provide a connection between these heads which will monious movement of the two heads during the type forming operation.

in illustrating the present invention, ithas only been deemed necessary to show those parts which relate to, the subject matter thereof. The main portion of the machine may be of any ordinary and well known type and the parts which compose the features of the present invention can be applied to any form of type making machine desired. As stated in the objects, the invention consists in two features, the first being the connection between the oscillating heads.

In Fig. 1 are shown two oscillating heads 9 and 10, each of which is mounted upon a suitable shaft 11. One of the heads, namely, the head 10, carries the type blank 10-, and the other, the head 9, carries the matrix 10", and the head 9 is power driven by any suitable mechanism which will impart a rocking movement thereto, as, for instance, an eccentric 10. Each head carries a bloc-k 12, which is mounted within a recess 12 in the body portion of the head and is held in place by securing plates 12, and is maintained in set position by a wedge member 13, or in any other suitable manner. It is understood that the head 9 and the head 10 are each provided with one of these blocks 12. Secured to each of the blocks 12 is a flanged which carries a matrix, and the other of plate 13, resting within a slot 12" in the 1 allowed between the heads during the foreliminate all slippage and insure the liarsecuring plate'12 flange 14, best shown in Fig. 4. This flange, as shown, 18 arcuate m formatlon and 1S adapted to rest within a circular groove'15 in a disk 16. This grove is produced, as more clearly shown in Fig. 4:, by forming a flange 17 on the disk, and by inserting into the center of the disk a threaded member 18, which terminates in a tapered head 19, which may be termed a hub. One of the faces of each of the flanges 14 is tapered so as to correspond tothe tapering formation of the head 19.

' As heretofore stated, each block 12 is provided with a plate 13 so that, as will be seen from a study of Figs. 1, 2 and 4, there '1 are two of these plates opposed to one another,and each having an arcuateshaped flange 14 resting within the groove 15. As the blocks 12 oscillate back and forth by the movements of the head 9, taking this head to be the power driven one, through the medium of the engagement of the flange 14 with the groove 15, the disk 16 will be raised and lowered in conformity with said movements. This will cause a corresponding 2 oscillation of the head 10 through the me-' dium of the engagement of the plate 13 of the head 9 with the disk 16, and hence a corresponding oscillation of the heads 9 and 10 around the centers of the shafts 11. By this 1 arrangement, a harmonious oscillation of the two heads is effected, and this is produced without the use'of teeth or similar contrivances, which are liable to become worn by wear and permit of a lost motion or play in the movement of the heads. If the parts of this connection should become worn during usage, the play can be taken up'by manipulating the screw-threadedmember 18 so as to force the tapered head 19 farther inward and into proper engagement with the flanges I 14 of the plates 13*.

Another feature of the present invention lies in the provision of means for locking a type carrying member to one of the heads, and also to the means for mechanically ejecting the typefrom the type carrying member. By referring to the plan view of the head 9, which is shown in Fig. 2, it will be seenthat said head comprises a body portion 20, which is cut away to allow of the interposition therein of a type carrying member 21, which consists of a block-like portion 22 and an arm 23. The arm is mounted upon'the shaft carrying the head 9. Thetype carrying member is locked to the body portion of the head 9 by means of a latch 24, which, as shown more clearlyin Fig. 2, is mounted within a recess 25 in the head 9. This latch is held normally projected by a leaf spring 26, and, in addition, is engaged by a coiled spring 27, the leaf spring, when thetype carrying member is thrown into lockedposition, tends to pull and having a projecting! the forward end of "t-he latch over into tion by means of a hooked clamp 28, best shown in Fig. 2. y This clamp is mounted upon a pivot 29; and a handle 30 is provided, which is mounted upon a stem or shaft 31, said handle being provided with a lug or cam 32, which, as shown in F 2, rests against a portion of the clamp 28 and serves to throw and, maintain the clamp in locked position. This arrangement affords a very firm and eflicient means of clamping the type carrying member to the body of the head, and insures against movement of the type carrying member with respect to the head, which, obviously, would be very undesirable, since it would allow of a slippage between the matrix and the type'blank, thus producing a type having imperfect characters thereon. When the type carrying: V member is swung clear 'of'the swinging head,

the spring 27 will then act to throw the latch back and hold it in place to be thrown to locking position. When the type carrying member is thrown back to normal position, after the type carrying member en gages the spring 26, the latch isthrown forward into the position shown by such engagement. V Means for ejecting the type are shown, which consist of a series of pins 33 project ing through rests in a block 34: held within the type carrying member 22; and said block is provided with a groove 35, in which rests theblank 10 of the type to be formed.

The pins 33 are carried by a head 36, to which is connected a stem 37, resting against a portion 38 of the stem'or shaft 31. This portion 38, as best shown in Figs. 3 and 6, is partially cut away so as to make its outer periphery of an eccentric or cam formation. A spring 39 is provided, which tends to'maintain' the stem 37 in engagement with the eccentric portion 38 of the shaft 31. The operation of this portion of the device is obvious from a study ofthe drawings. When the shaft 31 is turned through half a revolution, it moves the cam portion 38 into a position opposite to that shown, and the spring 39 will act to throw the head 36 rearwardly and retract the pins 33 from the slot 35. This will be the position the parts assume when the characters are being formed on the type. The position shown in Fig. 6 is the position assumed by the parts when the type is being formed. In the position the pins assume when performing the ejecting operation the pins 33 project intothe groove 35 in a manner to force the type outwardly therefrom. It will be noted that the handle 30 is keyed or otherwise secured toithe shaft 31, and that it is the rotative movements of this shaft ,from the locking member,

center,

ber. Vhen the handle is swung, however,

to jbe 'released so as to permit the clamp the ejecting inech anism moves into position toper'form the ejecting operation, holding member is and swung upwardly released from the head around its pivotal upon which the head 9 is mounted, the ejecting mechanism will have acted to torce the type out of the groove 35 and place it in position where it can be readily extracted from the type holding member by the oper,- ator. g
