SPECIFICATION forming part of Letters Patent No. 735,737, dated August 11, 1903.

Application filed December 11,1902. Serial No. 134,855. (No model) To aZZ whom, it In/coy concern;

Be it known that I, OARL'EDUARD FLEM- MING, manufacturer, residing at 164 Hauptstrasse, Schonheide, Erzgebirge, Germany, have inVe-nted'certain new. and useful Improvements in Machines for Drilling andFilling Brush-Backs, (for which I have applied for a patent in Germany, datedSeptember 15, 1902,) of which the following is a specification.

In the machine for drilling and filling brush-backs described in the specification to United States application, Serial No. 74,231, filed September 3, 1901, the movable frame of the automatically-operating machine with horizontally-placed tools carries all the mechanism requisite for the shifting of the slides carrying the brush-backs inclusive of the templet-disk, so that only the movement of the templet-disk and that of the frame have to be effected from the fixed framing. With this arrangement of the machine irregularities may occur in the working, because the ratchet pawl after the movement of the frame does not again engage with one of the teeth-spaces of the templet-disk in particular when small brushes are to be made, and consequently the distanee'between the teeth of the templet-disk is very small. According to the present invention the said irregularities are obviated by also mounting the ratchet mechanism upon the movable frame, so that the ratchet-pawl remains in gear with the templet-disk while the frame is being moved. By this arrangement also the ratchet mechanism is rendered more simple of con-'- struction.

On the accompanying drawings the improved arrangement ofthe ratchet mechanism is shown applied, by way of example, to I a machine having a frame with rectilinear to-and-fro movement. V I

Figure 1 shows a side view, and Fig. 2 shows a part perspective View, ofthe upper part of a machine; and Fig. 3 is a side elevation, and Fig. 4 is a top plan view, of a complete machine embodying this invention.

As shown in Figs. 3 and 4, the camewheel 3 is turned by means of the main shaft 1, which is arranged in the rigid frame e of the machine and is driven, by pulley 2. The 1ever 4, which is pivoted at one end to the frame e, is reciprocated by means of this cam-wheel. At the other end of the lever 4 is a shaft 5, to the ends of which are attached two rods 6. The latter are pivotally conoted at 9 to the main frame and are provided with slots 10, which engage pins 11 on a movable frame O. By turning the shaft 1 the frame O is caused to'reciprocate in guideways 12 in the frame e.

The ratchet mechanism is mainly the same as described in the said former patent, and the corresponding parts are marked with the same reference letters and numerals. The movable frame 0 carries in the known manner the templet-disk 7, the step-by-step motion of which is effected by the pawl 2 1, spring 25, and 'doubleended lever 22. These parts are mounted on a support a, fixed to the frame 0. In this example of construction the two-ended lever 22 has connected to it a second twoended lever 1), whose pivot c is mounted on the frame 0, and whose hook-shaped end dis in proximity to the fixed framing of the machine. On the fixed fra'ming e, which serves as a guide to the moving frame 0, is fixed a blade-spring f. As soon as the frame 0 moves away from the machinethat is to say, to the right hand at Fig. 1,.the hooked end at of the lever 19 bears against the fixed framing e, (the position shown at Fig. 1.) On the further the spring f, and thus the two-armed lever 22 is turned and the pawl 24 raised. When the frame Omoves to the left hand, the curved end 01 of lever 19 sinks again, and the pawl *24 consequently also sinks. The spring 9 serves for insuring the said motion of lever b.

When the machine is required to make a larger ora smaller number of holes in the brush-backs,. so that the pitch or the teeth of the templet-disk 7 requires'to be altered-, 'the ratchet motion. must be made to take place correspondingly earlier or later. For this purpose the abutment-piece h on the framing e for the curved lever is made adjustable in a guide 1'.

Having thus particularly described the ma nected with double levers 8, which are pivmotion to the right it'is raised, together with ture of my said invention and the best means I know of carrying the same into practical effect, I claim- 1. In an automatic machine for drilling and filling brush-backs with horizontally-placed tools, in which the movable frame carries all the mechanism for shifting the brush-backs, a fixed frame on which said movable frame is m0untcd,a ratchet device for the templet-disk mounted on the said movable frame and operated from the fixed frame, and means for holding said pawl in engagement with the templetdisk during the movement of the movable frame.

2. In an automatic machine for drilling and filling brush-backs of the kind herein referred to, a fixed frame, a movable frame mounted on said fixed frame, a templet-disk carried by said movable frame, a ratchet device for the templet-disk mounted on the movable frame which carries the mechanisms for shifting the brush-backs, a lever pivoted to said movable frame and operating said ratchet device, and an abutment-piece on the fixed frame with which said lever comes in contacton the movement of said frame, substantially as and for the purpose described.

3. In an automatic machine for drilling and filling brush-backs of the kind herein referred to, a fixed frame, a movable frame mounted on said fixed frame, a templet-disk carried by said movable frame, a ratchet device for the templet-disk mounted on the movable frame which carries the mechanisms for shifting the brush-backs, a lever pivoted to said movable frame and operating said ratchet device and an. adjustable abutment-piece on the fixed frame with which said lever comes in contact on the movement of said frame, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CARL EDUARD FLEMMING.
