Abstract: 22,299. Jordan, W., [Sanitary Sectional Brush Co.]. Oct. 9. Machines for making.-Relates to a machine for feeding a brush block in transverse and longitudinal directions to present it automatically to suitable drilling or tufting devices such as are described in Specification No. 22,298, AD. 1906. The block g, Figs. 5 and 6, is clamped upon a holder 100 having on its underside a gauge-plate, Fig. 6<a>, provided with ho!es 85 or slots 85<1>. The holder is mounted upon a carrier f by means of spring shanks 87 and is supported movably at its lower end, which is formed as a ball 90 in engagement with a spherical bearing 89, The ball 90 is slotted for the passage of a rock. shaf 110 provided with arms 109. A shaft 107 is fitted movably in eyes on the arms 109 and extends through the carrier f, being joined thereto by spherical segments 91 and cups 92 attached to the shaft. The shaft 107 is moved lengthwise to bring each of the holes in one row of holes in the block g successively under the drilling &c. devices, while the arms 109 are moved transversely, at intervals, to bring each row of holes successively under the same devices. To move the arms 109, a link 113 is provided at its other end with a pin 111, Fig. 8, which extends into a groove in a cam 114 attached to a toothed wheel 115 intermittently actuated by a pawl 117, which is itself operated by an arm on a shaft 134, Fig. 7, which also carries another arm 136 having a roller bearing against a cam 133, which is provided with two projections so that the pawl 117 is operated once for each halfrotation of the cam. The cam also operates a spring-lock 137, Fig. 8, through an arm 138, so that the cam is locked intermediate to its movements by the pawl. The cam is attached to another cam 124, shown in the plan view of the machine, Fig. 1, by which the longitudinal movement of the shaft 107 is effected. This cam is provided with a doubly-inclined circular slot 123, the edges of which may be notched as shown, in engagement with a pin 120 attached to a slide 122 and connected at 121 to one end of the shaft 107. The cam 124 is moved by a ratchet-wheel 126 actuated by a band-wheel, or by a pawl 141, Fig. 9, oscillated by rods 127, 128, Fig. 1. The rod 128 carries a lever in engagement with a cam upon the face of the gear-wheel e, which is mounted on the driving-shaft c and is in gear with a wheel e<1> upon the cam-shaft by which the drilling &c. appliances are operated. The cams 114, 124 may be readily detached and replaced by others. A pin 37, Figs. 5 and 6, serves to lock the brush-holder in position for drilling each hole in the proper place ; the pin is normally pressed into the holes by a spring on a rock-shaft 43 and is retracted by a cam which acts on the shaft 43. A dog upon the shaft 43 engages a clutch bolt, so as to stop the cam-shaft and thereby the drilling &c, devices when the pin 37 reaches the end of a row of holes. The whole machine is stopped, when the brush is fully tufted, by a pin 142 which, when the brush reaches its outermost position, operates mechanism to release a bolt 140, Fig. 1, by which the driving-pulley 129 is engaged with the shaft.
