SPECIEICATIQN m Application tiled March 22,

`erly space the matrix for different dies, and

relates more particularly to the feed-control: ling mechanism of such machines.

The object of the improvement is to provide I means for readily changingthe measurements of feed movementby an adjustment of parts connected With an escapement.

The invention consists in the devices and combinations hereinafter fully described, and particularly pointed out in the claims.

In the accompanying'drawings, Figure l is a plan view of the escapement mechanism of a matrix-making machine. Fig. 2y is a side I elevation of the same, showing the frame in section. Fig. 3 is a vertical section of the escape-Wheel, its supporting-sleeve, pinions, &c. Fig. 4 is a plan view of the pinions and rack. Fig. 5 is a detail of the auxiliary spring.

In said drawings, 1 designates a rack connected to a matrix-carriage that has a springtension in the direction of the arrow e.

2 is the escapement-Wheel, mounted on a sleeve 3, that turns on a post 4, which is secured to the machine-frame 5. On the sleeve 3 are

pinions

6, 7, and 8, held by a feather 9 from turning, and held in adjustment vertically by set-screws lO.u The adjustability of the pinions enables them to be severally placed in position to be engaged by th'e rack 1. The rack is pivoted to the carriage 25, so as to permit lateral movement of the outer end, and a spring 1l, secured to post l2, bears against the back of the rack to adj ust it to the diiferent-sized pinions and hold it to engagement'with them. vTo aid the rack in turning the scape-Wheel, especially when a small pinion is being used, there is provided an auxiliary coil-spring 13,- having one end attached to the sleeve 3,and the other to apost 14 on the machine-frame, and which tends to `first or minimum movement.

rotate the sleeve in the same direction as the rack. Over the scape-Wheel is a `lever 15, fulcrumed at 16, and carrying on `its arm 17 a pawl 18 for holding the Wheel against the 55 force of the rack. A second lever 19, pivoted to the former at thepwheel-center, carries the pawl 20, that is normally free from the Wheelf teeth. The projecting arm of Vthis lever has retreating steps 21, that are engaged by corref 6o and pins is such as to permit a movement of 4the scapewvheel equal to one tooth for the first step, two teeth for the second, three for l the third, and so on through the series.` Thus the movements are all exact multiples of the decrease the quantities of the matrix-carriage 'feed-movements permitted by these escapement movements, the different-sized interchangeable pinions 6, '7, and 8 are utilized.`

The escapement devicesare arranged to provide suitable proportionatespacings of the matrix forA dies cut on a given scale. If dies .of aditferent size are substituted, these escapement devices Will still control the proportions of movement, While the substitution of 8o the appropriate pinions will afford the proper quantity .of movement. If, for illustration, dies of a given scale of sizes are adapted. to be used in connection With a feed permitted by engagement of the rack 1 with the small 85 pinion 6, anda proper spacing for the difterent letters of the set is produced by the stepped lever and stops connected With 4the, escapement, and dies of a larger face'are then substituted for the former, the increased 9o` ably increase the matriiespacing for the p* larger dies, while the proportions of measurement of spacing for the varying `dies of the set is still regulated by the stepped lever and stops.

Patentable subject-matter disclosed herein roo and not herein claimed is reserved to be claimed in a pending application for patent To increase or 76 l filed by me March 18, 1889, Serial No. 303,657.

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

l. The combination, with the feed-escapement in a matrix-making machine, of pinions ment, .pinions of varying sizes carried on the scape-Wheel shaft, and means for adjusting the pinions severally to the rack, substantially as set forth.

3. In a matrix-feed mechanism, an escape- 4Wheel, a pawl for controlling its movement, a

rack and pinion for turning its spindle, and an auxiliary spring for aiding the Wheel rotations, having one end attachedv to a fixed object and the other to the Wheel-spindle, substantially as set forth.
