and a tack, and an automatic tack-guard adapted to prevent a tack from being thrown out of the line of said plunger. (9.) In a magazine hammer, a hollow hammer-head having a tack-channel leading to the nose thereof, a plunger therein, a spring-actuated tack-stop at the nose of the hammer-head, movable by and for the passage of the plunger, and a tack-guard consisting of a latch loosely mounted in the hammer-head in such a manner that a movement of the hammer which tends to dislodge a tack from the line of the plunger moves the latch into the tack-channel, sufficient space being provided for a tack in the tack-channel between the tack-guard and the tack-stop. (10.) In a magazine hammer, the combination of a tack-hopper and raceway, and a tack-retaining shoe suspended over the raceway and counterweighted so that the same movement of the tool which tends to throw tacks out of the raceway depresses the shoe. (11.) In a magazine hammer, the combination of a tack-hopper and raceway, and a tack-retaining shoe pivoted at the entrance of the raceway, and counterweighted so that the same movement of the tool which tends to throw the tacks out of the raceway depresses the shoe. (12.) In a magazine hammer, the combination of a tack-hopper and raceway, and a pivoted tack-retaining shoe suspended over the raceway and provided with a counterweight, the said shoe being normally lifted away from the gathering-blades by the counterweight, and so proportioned with relation to the counterweight that a movement of the tool which tends to jerk tacks out of the raceway also lifts the counterweight and depresses the shoe. (13.) In a magazine hammer, the combination of the tack-hopper D, raceway blades E, shoe s¹ pivoted at s³, and counterweight s², all substantially as described.

Claims.—(1.) In a machine for indicating the cost of goods sold by lineal measurement, a spring-driven roller having cost-markings in longitudinal and circumferential columns upon its periphery, such roller being controlled by ratchet and escapement gearing operated by tappets placed at intervals upon a measuring-staff whereby one or other of the longitudinal columns of figures is brought into position in relation to a fixed indicating-scale, substantially as specified and illustrated. (2.) A roller having cost-markings in longitudinal and circumferential columns upon its periphery, an indicating-scale fixed above it denoting the prices to which the circumferential columns are devoted, a spring for revolving the roller, and a ratchet wheel upon the roller-axle, controlled by an escapement, whereby one or other of the longitudinal columns is brought into indicating-position; slide-bars for operating and differentiating the action of the escapement, and tappets fixed upon bell-crank levers for operating the slide-bars, substantially as and for the purposes described and illustrated. (3.) The spring-driven roller a, the ratchet escapement wheel e, journalled upon the roller-axle and revolving with it in one direction, the pivoted loop h, and the spring w, the pawl-pin i, normally engaging the wheel e, the lever k upon the boss h³, having a pawl-pin l engaging wheel e when the loop is vibrated, the spring x operating upon lever k, and the stop-pin y, the whole substantially as described and illustrated. (4.) The spring-driven roller a, the ratchet wheel e, fixed upon a sleeve journalled upon the roller-axle, an arm f upon the sleeve having a pawl g', engaging with a ratchet wheel g fixed upon the axle, the sheave w' and the cord u coiled around it for returning the roller to starting-point, substantially as specified and illustrated.
