LIFTER ATTAGHIMENT FOR TYPE-SETTING TYPE-CASTING- MACHINES.

' to save time-andlabor in lifting the part known technically in this'art as theasseinbler. I

It will be understood that in operating a typesetting and typecasting machine of the kind above mentioned, it is necessary for the operator to lift the assembler repeatedly and also to restore it to its normal position.

i I In doing this much time is lost, and as the assembler is quite heavy the work has a great tendency to tire the operator and impair the general efliciency of his work.

I I seek therefore, to-enablethe operator-to'raise the as-.

sembler at will as many times and as often as he cares to do so, the ascent'of the assembler being always made 9 with uniform speed and both the ascent and return of the assembler being positive, yet the movement requiring practically no expenditure of energy on the part of the operator, the entire handling of the assembler being effected by-the applicationof power.

In effect, therefore, my invention consists in providing means whereby the operator exercises control over the lifting and lowiering mechanism for the assembler.

Reference is tobe had to the accompanying drawings 'forming a part of this specification, in which similar characters of reference indicate corresponding parts in ,7 all the figures.

The general framework of the typesetting machine is shown at 6. -At 7 8 are slideways and movably mounted within them is the assembler 9. The latter is old and well-known in this'art. Connected with the 'assembler 9 and extending below the sameis a bracket 10, and bolted upon this bracket is a headll from which depends a rack bar 12. This rack bar is made of sufiicient strength'toaremain rigid when s bjected to some little lateral strain at its lowerend. Mounted upon the lower end of this rack bar 12 is a head 13 provided with a beveled surface 14 and further provided with a vertically disposed slot 15 through which extends a screw 16.

By means of tlie screw 16 and-slot. 15 the head 13 may, within certain limits, be adjusted at any predetermined height, for purposes hereinafter described. Mounted firmly upon a rigid rest 17 is a pedestal 18 having a limb I 18 proj ecting laterally and upwardly therefrom. -Two bearings 18, 19, support a horizontal stationary shaft '20. Mounted upon opposite ends of the shaft 20 are nuts 21, 22 for the purpose of securing the shaft rigidly within the bearings of the pedestal. I

Revolubly mounted upon the shaft20 are two separate sleeves 23, 24 and keyed upon the sleeve 23 is a gear 25, engaging teeth of the rack bar 12 (see Fig. 3) for liftingthe assembler, as hereinafter described. The

sleeve 23-is provided with a disk portion 26 integraltherewith and three stud shafts 27 are mounted upon this disk-like portion and spaced equi-distantI Revolubly mounted upon the respective stud shafts 27 are planetary pinions 28; Encircling these pinions is an annular rack 29, theteeth 3 ;of which are disposed internally so as to engage the p anetary pinions 28 as inble in relation thereto is a hub 31 provided with a disk like portion 32--having a band channel 33 upon its outer periphery, this band channel being provided with an annular, portion IA. This annular portion carries an annular rack 29, mounted thereupon by aid of screws 35 spaced equi-distant, as indicated in Figs. 1 and 5. A'brakeband 36 lies withirrthe band channel and revoluble sleeve24 is fashioned at its end 37 insii ch manner that its end practically constitutes a pinion integral with'th'e sleeve 24. Keyed firmly upon the sleeve 24 is a gear 38. Mounted uponthe Y-shaped pedestal 18 and projecting'therefrom arelugs 39 between which is placed a'lever 40, the lattesbeing pivot-- ally, mounted upon a pin 41. A trigger 42 isprovided' dicated in Fig. 5., En'circling the sleeve 23 and revolu- -consequently' encircles the disk-like portion 32. The Y with an anvil portion 43 for engaging the bevel surface "14,.Ias hereinafter described and is mounted upon a pivot 44. A leaf spring 45 presses the trigger 42 constantly toward the left, according to the view shown in Fig. 3. The trigger 42 is provided with a notch 46 which fits upon a plate 47, the latter being journaled upon the pivot pin 41' and being also connected with the brake band 36. A leaf spring 48 is mounted upon the Y-shaped pedestal 18 and presses against the under side of the lever 40 for the purpose of normally holding the same in a predetermined position.

The, rear end of the brake band.36 is secured to a sliding block 3G mounted within a slideway 36". A screw 36 engages this block, and moves it toward the front or back of the machine, according to the direction in which the screw is turned. The latter is provided with a head 36 whereby it may be rotated at will. By turning the screw and thus sliding the block, the virtual length of the brake band may be changcdat will, the tension of the band regulated accordingly, and the sensitiveness of the lift of the assembler thus regulated at will. f

7 When the trigger 42 is turned to the right upon the pivot 44 according to the view shown in Fig. 3, the plate 47 is disengaged and the brake band 36 is loosened.

' The gear 38 mesheswith and is rotated by a pinion 49,

the latter being secured upon a key shaft 50 and turned constantly thereby.

The operation of my device is as follows: The operator proceeds with his work in the usual manner until he has occasion to lift the assembler 9. While the machine is running and the various parts occupy their respective positions, the key-board shaft 50 and the pinion 49 upon it turn the gear 38 at a constant rate of speed. This, of

course, causes the sleeve 24 and gear 38 to rotate con-.

tinuously. Normally the brake band 36 is loose, and consequently the planetary pinions 28 cause the annular-rack 29 to rotate idly in adirection opposite to the direction of rotation of the gear 38. HIen'cen ormally no power is communicated to the disk 26, revoluble sleeve 23 or gear 25, the three parts last mentioned always acting as a unit. The pinion 25, being for the time unable to turn, can, of course, communicate no motion to the parts adapted to be actuated by it, Suppose now that the operator wishes to raise the assembler 9.- He presses the lever 40 a very slight distance, using' comparatively little energy for the purpose. This causes the brake band 36 to stop rotation of the disk-like memhead ,13 arrives in such position that the beveled por-- tion 14 engages the anvil portion 43 of the trigger 42.

This throws the upper end of the trigger toward the right according to the View shown in Fig. 3 and, as above described, this releases the plate 47 from the control of the lever 40 and thus slackens the brake band 36.. This allows the annular rack 29 to rotate and of course power is no longer transmitted to the rack bai 12. The latter thereupon descends by its own gravity. The operator need not watch the lever 40 after the herein shown and described.

- rack bar for the purpose of disengaging salsa assembler is raised for the reason that when the assem bler reaches the proper elevation, its release and dethe assembler may be terminated withindifferent limits as to altitude. In pl'actice, therefore, all that i the operator finds it necessary to-do in order to raise the assembler to a predetermined height is to depress the lever 40 and for the moment pay no further attention to this part of the apparatus.

As the retarding power of a brake band is very great as compared with the degree of energy required to operate the brake band, the expenditure of energy in lifting the assembler may be considerable, and yet the operator may do an amount of work which, in its physical aspect, is so light as to be negligible.

When the operator wishes to regulate the sensitiveness of the lever 40, he turns the screw 36, thus adjusting the tension of the brake band 36, as above (lo-- scribed. Regulating the tension of the brake band also controls both the'speed and the momentum of the fall of the assembler after the latter reaches its highest point, and enables the operator to return the assembler as quickly as he considers advisable.

When the assembler is once started upward, the operator may stop it and lower it to any desired position as many times as he wishes; and also, no matter in what position the assembler may be at any partieu lar moment, the operator can readily send it to its upper limit. This feature, to wit, that-of lifting the assembler to or from any point selected, is considered important for the reason that it, increases the mobility of the machine and gives it a wider range of useiulnessl While I prefer gearing of the type above described for accomplishing the purpose indicated, I do not limit myself ,to this arrangement, neither do I limit myself to any particular shape for any of the parts Having thus described my invention, I claim as new and desire to secure by Letters Patent:
