The illustrationsshow in Figure 1 a rear viewoi a type-writer; Fig. 2, a partial plan of a type-writer; Fig. 3, a longitudinal section of a type-writer; Figs. 4 and 5, enlarged views of the retarding mechanism-5 Fig. 6, a detail ofthe indicating devices.
The carriage provided with thespacing-rack dis arranged to slide along the lined rod Z) and guide-rail c by any suitable draft mechanism. Supported upon thecarriage is the usual plates, and counected with the papertable of the platen is the scaled to enable the operator to position the Work with relation to the indicator 0, secured to a fixed portion of the machine.
Upon the trunnion-rail f is secured the bracket g, in which is pivoted the rocker h,
and at one end of the rocker the feed-dogs, having a slotj to permit vertical movement, is supported, the upper portion of the feeddog having a slot 7., so that the feeding vibration thereof may be limited by the strut Z, pivoted to the bracket g. At the opposite end of the rocker a check-dog m, is pivoted and connected to a link a, pivoted to the bracket g, to move only across the path of the carriage spacing-rack a. A spring tends to hold the feed-dog normally in contact with the spacing-rack and to depress the'checkdog. Links connect the release-key lever o "with a bell-crank p and the latter with a release-arm g, which is pivoted on the bracket 9. A frame 1' is pivoted to the bracket g and flexibly positioned by a yielding connection, as the spring is, fast to the release-arm (1 and in contact with a projection tfrom the frame 4", theupward movement of which frame is limited by an adjustin -screw 11,, threaded in a yoke depending thehefrom, that comes in contact at times with the trunnion-rail f. In the upper part of this frame 1' the retarding-dog v is pivoted, and the toe to of this dog rests under the shoulder a; of the check-dog. To vary the rate of vibration of the dog 'v, and hence the speed of the carriage under the draft'of its spring, the split weight 1 may be adjusted on a blade extending therefrom.
The above construction facilitates the accurate adjustment of the retarding-dog to the spacing-rack, which is important, the best results follow it the dogs have but limited motion from the rack, and as the trunnionrail is pivoted in the machine parallel to the spacing-rackthe frame 1', carrying the retarding-dog, will be maintained at constant distance from the rack by the adjusting-screw it when the release-key lever forces the yieldingconncction against the framor. Theyielding connection prevents the operator from improperly ail'ecting the vibrating parts in manipulating the release-key, as when the pressure is sufficient to position the frame 0' the feed-dog will be withdrawn from the rack, greater pressure only bends the spring 5 without changing the position of the frame r, and less pressure at once inserts the feed-dog to stop the carriage and allows the frame carry-.
ing the retarding-dog to fallback from the rack. When the operator strikes a symbolkey or the space-bar, the rocker causes the feed-dog i and check-dog'm to alternately come in contact with the rack a, the effect of which is to feed the carriage one space at each stroke; but if the release-key is touched then the lever 0, through the bell-crank p, turns .the dog 1; down, thereby lifting the check-dog in. into contact with the teeth of the rack ct by means of the toe to and the shoulder 56. The vibration thus established will continue while the release-key is depressed, and the rate of vibration may be regulated by moving the weight 3 attached to the retardingdog I. When the release-key is restored to .normal position, the feed-dog r3 again enters the rack a and stops the carriage.
The location of the release-key in the manual is an important feature, as no awkward reaching is required. The operator simply touches the key, watches the scale and indicator, and removes the finger when the carriage reaches the desired location.
Having described my invention, I claim and desire to secure by Letters Patent of the United Sta tes 1. In a type-writer, a carriage, means to move the carriage in its feeding direction and devices to allow the carriage to advance step by step, combined with automatically-controlled constant-speed-retarding mechanism for the carriage and means to free the carriage from the stepby-step devices and .to connect it to the constant-speed mechanism, without otherwise impeding the motion of the said carriage, substantially as described.
2. In a type-Writer, a supporting-frame, a carriage, a connection between the carriage and frame to move the carriage along the said frame in the direction of feed, and a spacingrack attached to the said carriage, combined I with a feed-dog and a check-clog thatare con nected with each other and the manual so the carriage may be thereby advanced intermittherefrom, combined with means for withdrawing the feed-dog from, and contacting the check and retardingdogs with, the spacing-rack, substantially as described.
4. In a type-writer, the combination with the carriage,'its draft mechanism and spacing-rack, of vibratory automatic devices for feeding" the carriage uniformly and means to change the number of vibrations in an interval oftime of the said automatic devices, substantially as described. V
5. In a retarding device, a bracket having a. rocker, strut and link, a feed-dog movable with relation to rocker and strut, a check-d 0g pivoted to rocker and link and meansfor depressing the feed-dog without affecting the check-dog, oombined with a retarding-dog and means for placing, the retarding-dog in operative relation to th'e 'rheckdog, substantially as described.
ii. In atype-writer,havingstep-by-stepand uniform-speed feeding devices including reiarding-dog, neans for adjusting the vibrathe retarding-dqg tory motion of the retardingdog, substan- 'tially as described.
In testimony whereof I have hereunto sub- 7 name this 27th day of December,
