MACHINERY FOR RUBBING TYPE.

SPECIFICATION forming part of Letters Patent No. 457,575, dated August 1 1, 1891. Application filed October 11, 1890. Serial No. 367,825. (No model.)

To all whom it may concern.-

Be it known that we, JAMES C. BIRCH and CHRISTIANDANCEL,bOtl1 citizens of theUn ited States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Machinery for Rubbing Type, of which the following is aspecification.

In Letters Patent No. 380,599, granted April 3, 1888, to George S. Eaton, assignee of George S. Eaton and James (J. Birch,a mechanism is represented for receiving type and passing the same along between two polished surfaces to equalize the type at the same time that the cutters remove from the base of the letter the projecting burrs.

The present invention is an improvement upon the devices set forth in the said patent; and the same consists in the peculiarities of construction and combination hereinafter set forth and claimed.

In the drawings, Figure 1 is a plan view perpendicular to the inclined bed. Fig. 2 represents the bed-plate with the parts above the same removed. Fig. 3 is a section of the equalizers and bed near the line x {I}; and Fig. 4: is a plan of the feeding mechanism with the bed in section near the line y 1 Fig. 3. Fig. 5 shows the feed-plate and steadying-finger.

Fig. 6 is a detached view of the slide and bolt.

from the under side and in larger size, and Figs. 7 and 8 show the lever and plate for the adjusting-screw of the equalizer.

The frame A, driving-shaft B, and bed C are similar to those in the aforesaid patent, and upon the bed 0 is a plate D extending up to the table D,u pon which the types to be rubbed are placed, and this plate D is perpendicular to the bed 0; but the bed and the plate are inclined to the horizontal line at about fortyfive degrees, and the stationary equalizer E.

is bolted permanently to the bed 0, and the movable equalizer F is adjustable toward or from the stationary equalizer E and between the guides G, that are permanently fastened upon the bed 0, and there is a screw 1'' for adjusting the equalizer F toward and'from the equalizer E. These parts, except as hereinafter named, are also similar to those in the aforesaid patent.

In practice we have found that in cases where an imperfectly-cast type was forced in between the equalizers and the machine was stopped thereby, the belt slipping upon the pulley V it was difficult to remove such obstruction without altering the adjustment of the movable equalizer in its relation to the stationary equalizer. To provide for this contingency we make upon the screw f a rigid collar 5, which is adjacent to the bearing 6, through which such screw f passes. This bearin g 6 is permanently fastened to the plate 0, and the distance between the rigid collar 5 and the side of the bearing 6 is such that the movable equalizer F can he slipped away from'the stationary equalizer E until the collar 5 strikes against the side of the bearing 6, and this movement can be given to the parts after the lever 7 hasbeen drawn back, there being upon this lever 7 a plate 8, the end of which is slightly beveled and notched, so as to pass over the screw f and between the rigid collar '5 and the bearing 6. Hence when the machine is in operation the pressure in equalizing the types is taken by the collar 5 upon the plate 8 and bearing 6, and when this plate 8 is raised by the lever/ the equalizer F can be moved back and any obstruction taken out from between the equalizers, and in doing this the screw f is not retated, nor the adjustment varied in the least, and the parts are returned to their normal position by pressing the plate 8 in between the collar 5 and the bearing 6.

In the aforesaid patented machine the base of the type rested upon the surface of the bed 0, and the pusher I moves such type along with the base thereof in contact with the surface of said bed. It has been found that the delicate edges of the base of the type are sometimes injured by the friction of the base of thetype against the surface of the bed 0. To avoid this difiiculty, we make use of a traveling table 9 within a slot 10,, that extends from the place of reception to the place of delivery of the types, and this traveling table 9 is connected with and moved by thecarriage N, that is supported by the portion (J of the bed 0. This carriage receives its motion in' substantially the manner described in the aforesaid patent, and it also carries the pusher I, which is connected to it, as before described, and the operative end of this pusher is immediately over the traveling table 9. Hence each type, as it is fed into the machine, passes down and its base rests upon this table 9, and the pusher I carries the type along between the equalizers E and F, by which'the surfaces of the type are smoothed and such type equalized, and during this operation the cutters M remove the burrs from the base of the letter, and during this time the base 'or lower end of the type rests upon the table 9, and this table 9 sets up closely against the lower edgeof the movable equalizer F. Hence such equalizers act efficiently upon the whole of the surface of the sides of the type during the operation of equalizing and rubbing.

In the aforesaid machine the surface of the equalizer F in line with the feed was notched to allow for the type feeding down between the two equalizers with freedom. We find it advantageous to make the equalizing-surfaces upon the equalizers E and Fsmooth and flat, andin the block portion of the stationary equalizer E in line with the feed a recess is provided for the feeder 11, which is in the form of a block sufficiently wide to correspond with the widest type, and it receives a motion from the line of the face of the plate D up to the face of the equalizer E, and this motion is given to the feeder by avrod 12 and lover P upon a fulcrum 14, and this lever is acted upon by a cam (shown by dotted lines in Fig. 3) and a spring 14, and this rod 12 is screw-threaded and provided with locknuts 15, which come up against the back surface of the stationary equalizer E, and they are so adjusted that when in contact there with the face of the feeder is accurately in line with the polished surface of the equalizer These lock-nuts allow for adjustment in case of wear, and there is a spring 16 between the jaw end of the lever P and the lock-nuts 15, so that the cam upon the driving-shaft B will act to compress this spring after the locknuts 15 come into contact with the rear surface of the equalizer E and the nuts 17 are behind the jaw of the lever P and they are adjustable, so that when the jaw of the lever P comes in contact with the metal at the end of the slot in the bed 0 the surface of the feeder 11 will correspond accurately with the surface of the plate D. The plate D is set back. from behind and below the surface of. the equalizer E a distance equal to the largest 'end to a small plate connected to the surface type to which the machine is adapted, so that the type may be fed down this plate D and'in front of and rest upon the feeder 11 during the time that the pusher I is carrying the preceding type through the machine. This allows more time for the operation of the feeding mechanism, and when the type is brought up to position it is held reliably between the surface of the feeder 11v and the polished face of the movable equalizer F, so that the pusher I acts uniformly in starting the type and carryingit through between the equalizers and during the rubbing operation. We find'it preferable to make use of automatic spring-pressure for detaining the types 'a slide 21 connected with the moving end of said lever 19 and adjacent to the lower edge of the plateD, and in a recess at the end of this slide 21 is a bolt 22, sliding freely but kept toward the type by a weak spring 23 and there is a second-lever 24, pivotedat25 and acting to draw backthe presser 26, and there is a contractile spring 27 acting upon the presser in the opposite direction. It;w-ill now be understood that the attendantisupplies the types successively between the guides q q andupon the table D and the presser 26 arrests their downward movement. At the proper time the presser 26 is drawnback by the lever 24, so that the type can slide down upon the plate D, and betweencthe guides q q, and simultaneously with this movement,whichdraws-back thepresser26,the slide 21 is moving in the opposite direction and the bolt 22 passes across the slot between the guides q q and the type is arrestedthereby, and this bolt 22 is drawn back at the proper moment to allow the t ype to slidedown upon the surface of the feeder 11 before said feeder carries the type up against the surface of the equalizer F, as aforesaid, and shoulda type become obstructed or temporarily detained between the guides q q, or should the attendant supply the types too fast between such guides, the type will not be injured by any positive motion given to the parts, because the presser 26 is moved toward the types by the contractile spring 27, which is too weak to injure the types, and the bolt 22 is moved toward the types by the slide 2l'and'the spring 23. Hence the types are not injured,.even when very thin, by being caught between the end of either the. bolt 22or the presser 26 and the guide q, and the feeding operation is uni: form and reliable.

The steadying-finger 7c is pivoted at its lower of the equalizer F, similar to that in aforesaid patent, and this steadying-finger lies in the slot between the guides q q and above the types, and there is a flexible spring 28 to press such steadying-finger to its position with a slight force; but the plate that carries the pivot of the steadyingwfinger, is slottedfor the screws by which it is connected to the equalizer F, and a spring 29 tends to press the block 70 away from the table D, and there is a screw 30 with a conical shank adjacent to the edge of the plate is, so that by screwing thisscrewv 30 downwardly and into the equalizer F the steadying-finger it will be moved toward the plate D, and when the screw is turned in the other direction the spring 29 moves such finger it; away from the plate D, giving more room for the types that are fed between the guides q and q. I

The stationary block S, with a curved end to guide the type as it is delivered from the machine to a rule or holder '1, is similar to that in the aforesaid patent, and theblade r carries the type into the groove between S and S; but in order to allow the traveling table 9 to carry the types to the place of delivery such table 9 is preferably made as a thin plate, as shown in Fig. 41 110 pass over the beveled surface of the bed 0 at the place of delivery of the types, and the parts are to be so timed that the table pauses at the end of its movement and the blade r carries the type off the table 9 and in between the blocks S and S and holds the same in its position while the table 9 commences its return movement, thus entirely preventing the movement of the table 9 from interfering with the proper delivery of the type from the machine.
