Patented Jan. 25, ioie.

Application filed August 20, 1911 Serial No. 578,079. Renewed June 21, 1915. Serial No. 35,427.

To all'whom it may concern Be it known that .we, ARTHUR G. BAKER and FRANK -W. KNO'I'I, citizens of the United States, residing at the city of Detroit, county of Wayne, State of Michigan,

have invented certain new and useful Imrovements in Distributors for Type-Setting achines, of which the following is a specification. This invention relates to improvements in distributers for type-setting machines.

The objects of the invention are: Flrst, to provide an improved electrical means for actuating a type-distributing.carriage. Sec- 0nd, to provide an improved construction of carriage for carrying the dead matter to be distributed to the channels of a typesetting machine. Third, to provide an mproved construction of type-setting machine wherein the type carriage, W1 h the dead matter, can be readily returned over the mouths of the channels without undue frie tion on the type.

Further objects, and ob ects relating to structural details, will definitely appear from the detailed description to follow.v

We accomplish the objects of our invention by the devices and means described in the following specification.

'The invention is clearly defined and pointed out in the claims. A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure 1 is a front elevatlon View of our improved type-distributer in position on a typesetting machine, the rear ratchet bar 18 not being shown. Fig. 2 is an enlarged 49 rear elevation of the same with a portion only of the frame track and ratchet bars illustrated. Fig. 3 is a plan view of the structure appearing in Fig. 2. Fig. 4 is a detail elevation View, partially in section,

.on a line corresponding to line 4-4 of Fig. 3, showing details of the wedge-bar, which elevates the type out of contact with the channels, and the related parts. Fig. 5 is an enlarged detail sectional view, taken on 5 line 55 of Fig. 1, showing details of these same parts at that point. Fig. 6 is a detail view of one of the type 23, showing the nicks therein. Fig. 7 is an enlarged detail plan view ,of a portion of the tops or mouths of the channels, showing the wards those ments of the type carriage 3.

25 for engaging the nicks 24 of the type. Fig. 8 1s a detail sectional view on a line corresponding to line 8 8 of Figs. 4 and 7, showing details of the channels in the ear riage 3 and of the channels of-the typesetting machine below. Fig. 9 is an en-' larged detail sectional view of one of the channel walls, taken on a line corresponding to line 99 of Fig. 7, showing the slant of the upper end of the wards 25.

In the drawing, the sectionalviews are taken looking in the-direction of the little arrows at the ends of the section lines, and

similar numerals of reference refer to similar parts throughout the several views.

Considering the numerals of reference,

the mam frame 1 of the machine is provided with the usual type-channels 2 having suitable wards 25 having slanting tops for engaging the nicks 24 in the type 23. A top rail 4 is provided for the carriage 3 to travel upon, the rail being supported by suitable posts or supports -5-5. The posts 5+5 are/secured to the top of the frame by bolts'or cap-screws 6 and to the rail 4 by-cap-screws .or bolts 7. The carriage 3 1s provided with carrying wheels 8, which are supported on the axle journal pins 9-9 on the cross arms 10. A guide wheel 11 engages the rear side of the rail 4, and is supported on vertical journal pins 12 on the bracket or arm 13, extending rearwardly from the carriage 3. A pair of guide wheels 14 is supported on vertical journal pins 15 in brackets 16 on the back side of the carriage 3. These guide wheels or rollers 14 contact with the flat back sides of the toothed ratchet bar 17, which toothed rack bar 17 with the rack bar 18 is secured to the posts 5 by suitable bolts or capscrews 19.- These rack bars 17 and 18 are provided with ratchet teeth 20 and 21, respectively, those teeth 20 on the bar 17 pointing toward the left of the machine and 21 on the bar 18 pointing toward the right of the machine. These ratchet teeth cooperate with the pendulum and pawl devices for feeding and controlling the move- The type carriage 3 1s provided with vertical channels 22 in which the dead matter or type 23 is placed for distribution. The carriage'is advanced step-'by-step over the channels 2 in a manner hereafter to be de scribed. [The type are provided with distinguishing nicks 24, which are engaged by suitable corres onding wards 25"on the.

sides of the c annel type bars 25 in the usual way in distributers of this class. The wards 25' are slightly beveled or slanted at their upper. ends,-see Fig. 9,to insure free passage of the type over the same. The

tops of the channels are formed of bars 25,

- which rest in notches 62 63 in the sides of the frame, and are retained by the removable bar 64, projecting into notches 65 in the ends of the bars 25.

A longitudinal rectangular groove 27 is cut in the under side of the carriage 3,see

V-shaped. A pawl 34, having a'double' bev eled tooth 33 corresponding to and coacting with said V-shaped notches 32 and 33, is pivoted between guide arms 36 on the ri hthand side of said carriage 3. This paw 34 is urged downwardly by the spring 37 and urges the tooth 38 into yielding engagement with the notches 32 and 33 on the upper side of the bar 26.. i

The carriage moves step-by-step from the lefthand side of the machine toward the right,'the pawl 34, with its beveled tooth 33, engaging in the notch 33 toward the lefthand end of the bar 26. This carries the bar toward. the right until the finger-29 contacts with the stop 30. The carriage thencontinues its travel toward the right step-bystep over the bar until the pawl 34, with its tooth 33, engages the notch 32. When the,

carriage reaches this point, which is the end of its travel, the'type 23 in the channels of the carriage will have beenelevated up onto the bar 26, and, as thebaris now engaged by the said tooth, when the carriage is re- "turned to the left, the bar will be carried I with it until the finger 29 contacts with the oil from the bar to the level space at the left across the channel mouths.

the extreme left in its movement, the '34 Wlll. again engage by its beveled tooth 33 stop 31. When the carriage has been moved to this position, the bar 26 will reach entirely The continued movement of the carriagewill pass the same of the machine. When the carriage reaches pawl in the notch :33, and, as the carriage is advanced by the Step-by-stepmovement toward the right, the bar will be carried in that direction"' until'thefinger 29 contacts with the stop 30, when the carriage will again move onto the bar, repeating the evolution just resuflicient time to insure the pull of the magferred Itis thus clearthat the type' are raised out of contact with the channel:

mouths during'the return of the carriage, and, consequently, the carriage is easilyreturned.

a Y 1 The carriage is advanced by the action of the double pawl 38 onthc. teeth 21 of the bar '18. The double pawl 38 is pivotedgfl: 39

on the armature 40, which armature is pivoted at41, on the back side of thecarriage 3.

pin 46 limits the downward movement of the pawls, and, by the action of the same on the cam. surface 47, raises them out of engagement with the teeth 21 ofthe rack 18, except when the armature40is pulled by the magnet. A finger 52: is secured to the arma-' ture 40, and'is urged upwardly by the spring 53,-see Fig. 4. The movement of the armature 40 in this direction is limited by the adjustable stops .48, secured to the back side of the carriage 3.

- Double detent pawls 49 are pivoted at 50 on the backside of thecarriage 3 and are connected by a link 51 to the arm 52. These J double pawls 49 are yieldingly-associated together' by the spring 49,*,see Figs. 2, 3' and 4,andvit will be readily seen that, whenever the magnet 42 acts upon the armature 41, these detent pawls will be thrown downi wardly and will engagethe teeth 20 on the" bar 17, and are timed "s0 'thatthe carriage v will be advanced but a singlestep on each impulse.

The contact of the magnet is controlled by the pendulum 54, which is pivoted by. the rock shaft-55 in suitable journals on the top of the arm 13. The arm 56 is carried bythis rock shaft. 55 and'is provided with a contact finger 57 which swings into contact with the contact button 58 on the spring 59.

- The spring 59 is secured by the insulated binding post 60 to the arm 56, which is connected to the conductor 61, delivering current to or from the electromagnet 42; {A

lightspring 62 connects; the;upper end of thelink' 51 to the spring 59, providing a yielding connection between these parts. The'source of electric current may be a battery, as illustrated, or anyother adequate supply.

. From this description, it will be seenthat,

when the pendulum 54 swings, the contact 1125 finger .57 will swing .into contact with the contact button 58.- This closes the circuit and causes the electromagnet 42 to act. As 4 there is a yielding spring contactbetween these parts, the contact is preserved for a 75 This armature is acted upon by-the ,electroa K portance.

net on the armature 40. This, through the yielding contact, gives the pendulum an impulse by drawing the spring 59 down against the arm 56. The pendulum then swings to the right, and the contact between the finger 57' and the button 58 is broken, and the spring 53 causes the armature 40 to return to the normalposition indicated in Fig. 4. When this pendulum movement occurs, however, and the magnets act, the pawls 39 engage the teeth 21 of the rack 18, which forces the carriage one step toward the right. Immediately after these teeth have engaged the teeth 21 of the rack 18, the detent pawls 49 are forced downwardly and engage the teeth 20 of the rack 17 which are pointed in the opposite direction, and the carriage is compelled to advance but a single step and there can be no overthrow. Also, this movement is very definite and brings the type exactly to the right point to fall into the channels beneath.

It will thus be seen that the carriage of the distributer is advanced very rapidly and very definitely by a very positive movement to exactly the right point for the distribution of the type. This is of very great im- At the same time, it will be observed that, owing to the other parts of the distributer, the type can be very readily returned to the initial position without being compelled to pass over and in contact with the channel mouths. This makes the distributer very effective and insures proper distribution of the type, without danger of breakage and it insures the smooth operation of the entire device, so far as type distribution is concerned.

The method of elevating and protecting the type from engagement with the mouths of the type channels is important, and it can be made use of with various means of ad vancing and returning the carriage. Also, the particular electric means which we have shown for propelling our carriage could be made use of with any style of carriage. Our

improved means of supporting the carriage on its rail might be made use of with any carriage.

We mention these facts, because we consider each of these features important, but, however, they lend themselves particularly well to each other. It is necessary that the carriage be advanced with strong force, and

definitely in order to advance it onto the wedge-shaped bar, and the particular way in which we support the carriage prevents friction of rubbing between the parts and insures the full action of the propelling dev1ce.

Many variations, no doubt, will. suggest themselves to those skilled in the art to which our invention pertains. We have shown the form in which we prefer it. We

, double desire to claim the same specifically and also broadly.
