CHARLES H. SHEPARD, OF NEW YORK, N. Y., ASSIGNOR TO WYCKOFF, SEAMANS & BENEDICT, OF ILION, NEW YORK, A CORPORATION OF NEWV YORK.

SPECIFICATION forming part of Letters Patent No. 755,061, dated March 22, 1904.

Original application filed July 1'7, 1902, Serial No. 115,922. Divided and this application filed January '7, 1903. Serial No. 138,151. (No model.)

employed, and more particularly to that character of machines wherein the platen is shifted for upper and lower case writing; and the ob ject of the invention is to provide simple and v cflicient means for effecting a release of the carriage whether it be in the operative position or be swung back to inspect the writing.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a side elevation of the upper portion of a No. 6Remington type-writing machine with the features of my invention shown and applied thereto. Fig. 2 is a side elevation ofsome of the parts illustrated in Fig. 1, the feed-rack being shown in the engaged position. Fig. 3is a like view of the same, showing the feed-rack disengaged from the pinions and the 'platen in the operative position. Fig. 1 is an end view of the parts shown in Figs. 2 and 3, the View illustrating the platen swung back to the inoperative position and the feed-rack disengaged by the release-key. Fig. 5 is a detail perspective view of a portion of the carriage-release mechanism.

The present case is a division of my application, Serial No. 115,922, filed July 17, 1902.

The frame 1 of the machine is surmounted by a top plate 2, which has upwardly-extending lugs 3, that support a traverse-rod 1, the top plate likewise having upwardly extending lugs 5, that support a traverse-rod 6. The truck 7 is provided with a rearwardly-extend- Y chine.

ing arm 8, that is forked at its rear end for engagement with the flanged sleeve 9, supported and sliding on the traverse-rod 6. The truck carries rollers 10, that are supported upon the traverse-rod 4., so that the truck is guided and supported upon the two traverse-rods 4 and 6 in its movement from side to side of the ma- The truck has linksll, pivoted thereto at 11, as indicated in Fig. 3, and the upper ends of these links are in turn pivoted at 12 to a platen frame or carriage 13, that supports a platen 14., which is adapted to revolve therein. The pivots 12, which unite the platenframe to the links 11, are extended at their ends and cooperate with screw-stops 14. to limit the backward and forward movements of the platen-frame when it is shifted for upper and lower case writing. The forward cross-bar of the platen-frame carries the roller 15, that bears upon a shift-rail 16, supported, operated, and held by any suitable shift mechanismsuch, for instance, as that ordinarily employed in the No; 6 Remington machine whereby the platen-frame carrying the platen 1 1 may be shifted transversely for upper and lower case writing and may be held in either the upper or lower case position.

The truck 7 is provided with depending ears 17, to which curved arms 18 are pivoted at 19, and these curved arms extend over the top of the traverse-rod 4 and carry at their forward ends the feed-rack 20, adapted to-mesh with a feed-pinion 21, fixed upon a shaft 22, that is supported in a bearing 23, carried by the top plate of the machine, and the shaft is operatively connected at its rear end to an escapement-wheel 2 1, that cooperates with suitable feed-dogs (not shown) in the usual manner.

Projecting' forwardly from one end of the feed-rack is an arm 25, that terminates in a pin 26, which extends at an 'angle'thereto and is received within an opening 27 in an angle or elbow lever 28, pivoted at one end 29 to the truck. This angle or elbow lever carries a laterally-projecting headed pin 30, that carries an antifriction-roller 31. Pivoted to one end of the platen-frame, and preferably the left-hand end thereof, is'a release-key lever A V I i 32, the pivot of said lever being indicated at 33, and the forward end of the lever is fashioned into a finger-key 3a where it extends to the front portion of the platen-frame, whereas the rear end of the lever extends beneath the antifriction-roller 31, carried by the elbow-lever 28, and is preferably rounded or curved on its upper contact-face, as indicated at 35. The release-key lever has an enlarged portion 36, that is slotted at 37, where it receives the stem of a headed screw 38, the stem of said screw passing through the slot and taking into a threaded opening in the platen-frame in order to guide thelever and prevent a lateral deflection thereof. A bent leaf-spring 39 is secured at one end to the platen-frame and bears at its other end against a pin 40, which projects' inwardly from the enlarged portion 36 of the release-keylever, and the tension of the spring is exerted to normally maintain the lever in the position indicated in Fig. 2.

From an examination of Fig. 1 it will be seen that the normal disposition of the parts is such that the release-key lever is entirely disconnected and out of contact with the elbow-lever 28 and, in fact, with all portions of the truck, so that the platen-frame is free to be shifted forwardly and back to change the case position of the platen without interference by the release-key lever. A depression, however, of the finger-key 34 is effective to depress the forward end of the lever against the tension of its spring, thereby elevating the rear end of the lever and bringing it into contact with the antifriction-roller on the elbow-lever 28. The effect of this movement is to raise the feed-rack or to move it transversely and out of engagement with its cooperative pinion 21, as illustrated in Fig. 3,thus releasing the carriage from its feed mechanism. When the platen has been swung back to the position represented in Fig. 4, the relation of the parts is somewhat changed; but the inner end of the releasekey lever is nevertheless in a position where a depression of the release-key will cause the rear end of the lever to be moved in the clirection of the arrow in Fig. 4, and this movement is effective to turn the lever 28 on its pivot, thus lifting the feed-rack from engagement with its cooperating feed-pinion. It will therefore be seen that the release-key lever extends to the front of the carriage, where 1t may be readily grasped, and is at all times maintained in such position that it may cooperate with its associated parts to release the carriage, whether the platen be-in the operative position (illustrated in Fig. or in the inoperative position (illustrated in Fig. 4) and without interfering with the shifting movements ofthe platen-frame and platen.

My invention will be found of great value 1n type-writing machines with swinging platens and wherein printing-point indicators are employed, inasmuch as it is desirable in such machines to move the carriage when it is swung back, as illustrated in Fig. 4, in order that the carriage may be moved at this time to bring the exact. point where the insertion is to be made for instance, into register with the printing-pointindicatorand in order that the registration may be readily attained while the parts are within the view of the operator and without first swinging the platen down to release the carriage and again swinging the platen back after the carriage has been moved to see if-the proper position has been attained.

Various changes may be made without departing from the spirit of my invention.

Thus, for instance, while I have specifically described the embodiment of a laterally-movable feed-rack carried by the carriage for engagement with a feed-pinion from certain aspects of my invention any suitable cooperating feed elements may be employed, and while my invention is particularly adapted for shifting-platen machines it should be understood that from certain aspects the invention is not limited to machines of that character. Then, again, I have made a distinction between the platen frame and truck throughout the specification, and from certain-aspects of my invention these distinctions may be regarded, whereas from certain other aspects these parts may be regarded generally as the carriage.

What I claim as new, and desire to secure by Letters Patent, is
