D ec. 13, 1932. E. THORELL TYPE SOLDERING DEVICE Filed Jan. 15, 1950 Patented Dec. 1.3, 1932 UNirED PATENT FFICE EDWN THORELL, OF WEST HARTFORD, CONNECTICUT, ASSIGNOR T0 UNDERWOOD ELLIGTT FISHER COMPANY, 0F NEW YORK, N. Y., A CORPOBATON 0F DELAWARE TYP-E-SOLDERING- DEVICE Application med January 15, 1930. seal No. 420,865.

This invention relates to apparatus for use when attaching the slotted types to the tips of the type-bars of typewriting machines.

Heretofore a fixed magnet was used and the type was dropped against a bottom gage, where it was held by the magnet. However, the slot in the type is over-width for the typebar, and it was found that the types were not accurately or uniformly located, and that their sides were not properly aligned. Moreover, during the soldering, the weakly held types were apt to be knocked by the stick of solder, causing trouble. n

According to another method accuracy of alignment has been secured by -fastening each type in a cradle, the latter having accurate dimensions, and then holding the cradle accurately and firmly in a'jig in which the typewriting machine was also mounted, and then swinging the type-bar into its position in the type-slot, and then applying the solder. l

It is an object of the present invention Vto reduce the cost of such soldering fixtures and to reduce the room taken up thereby, and avoid the necessity of fitting the typewriter upon a jig and of securing the jig to a workbench. It is one of the aims to simplify, cheapen and improve type-soldering appliances.

In place of locating said type in a matrix by means of its projecting type-face, the 1nvention eliminates'the necessity for providing a complete set of combined gages and matrices, one for each type-face, and also avoids the necessity of selecting each matrix preparatory to attaching the type thereto in each case, and of providing proper holders for the matrices when not in use.

t 4 A feature of the present invention is that the type is irst located or aligned at both the bottom edge and the side edge, and is then clamped and `held in said position preparatory to the soldering. After` the type is clamped, the type-bar isswung into the slot in the type-head and then the solder is applied thereto. After the type is so soldered, the clamp is easily and quickly released, and the type-bar, together with its type-head, is swung away. In this manner the type can be h eld mechanically in a perfectly centered posltion, which insures accurate type soldering. It is a feature of the present invention to gage each type as accurately as was practicable with the use of the old gage-matrix, while dispensing with said gage-matrix. To this end, the face of the type is set back against a fiat type-face gage, which may consist of a vertical face of a stationary plate. This lo- Cates each type-face parallel with the faces of all the other types and insures that the face of the type shall be presented accurately to the platen, since said type-face gageplate occupies the position whichV is to be subsequently occupied by the platen in the typewriting machine. j

The type is at the same time set sidewise against a side gage, which engages the side of the type-head. This provides for accuracy of side-spacing of the type, or, in other words, 'l

brings thetype into an exact central position in the typewriting machine.

The type is also set down against a bottom gage, which consists of a razor-edge, which lies flat back against the face of said tyce- 'v have been: previously set, so that the type is 8 now exactly in` its printing position in the typewriting machine. Then the type is clamped in place.

This accurate production of types enables the present type-soldering device to afford extreme accuracy, since it clamps veach type- Yhead at exactly the same position, after first having its bottom and side edges aligned.

The type-bar isswung up, and its tip'enters the slot in the fixed type-head. This slot is made over-width, so that the type-bar may enter therein, notwithstanding that the tip of the type-bar may be a little bent or twisted, or otherwise out of place. Then the solder is introduced into the type-slot, thus soldering the type to the bar while the type still remain in it perfectly aligned and in level position. The bent, twisted or misplaced condition of the type-bar still persists, but the type-bar must nevertheless, bring the type always tothevsame accurately-aligned position, when the typewriter-key is being operated. The position ofthe type is not affected by faults of the type-bar to which it is attached.

The foregoing'gages are mounted upon a jig which is very simple, compact and cheap, and is attached to the typewriting machine itself, having accurate bearings which fit upon the rear carriage-guiding rail. The

fixture lis leveled in the machine, and rigidly securedx- The gages-are adjusted to` a master type-bar, which carries a masterl type, which is preliminarily inserted in the machine in typewriting machine vhavmg'a type-soldenl thelsame position as a regular type-bar, and

vis brought to printing position against the usualstop-ring of the typewriter. While the master type is held in this position, the severalsgages of the jig are, one by one, brought into exact position with reference to theemasterftype, thereby assuring that all of the printing itypes. which, thereafter, one'by onepare setto said gages, willl occupy the eXact positions predetermined by the master type.: Thus the need of aset of individual gage-matrices is avoided, and'alignment is eifectedby means of avery simple:A and inexper'isivedevicereadily attached to the ma-r A plate is then mounted upon one member-I of sai'dfanglebracket, and, by turning a screw, said plate,- upon which the type-clamping j awsfaredirectly mounted, may be tilted forward toV xproper position. 1 A bottom typegage is adj ustably mounted on said plate. An adjustable lblock acts as a side type-gage. Thisg :block-is also iXedA upon said plate.

The ytype is firstpositioned against the bottom gage, yand Vthen moved sideways against-the 4side gage or stationary block. Thenacam-lever moves a sliding jaw against Saidetypeto clamp it in position against said stationary block said slidable member being under aspring tension.

Said/master type, which is very accurate, afterfbeingmounted on the type-bar segment, is swung against the segmentestop ring to typplate, or the plate upon which the blocks are directly mounted, may be adjusted andV then locked-fast. This adjustingl need only be done once.

In some cases, especially foreign types, such as Russian, it is found necessary to have a different adjustment.v and a top gage is provided, so that .the top of the types are aligned instead of the'bottom of said types. The top aligning bar is similar in construction to the bottom aligning bar.

. Upon the frame 10 of thetypewriting machine is secured a cylindrical carriage-track or way-rod 11.- 4The sides of the typewriter frame are connected by a tie-rod 12,fuponA which is secured a segment'l, in which type-V-v l bars 14. are hingedupon a fulcrum-rod 15 f and work in radial slots 16. The types enter frame of the typewriting machine...v The jig L comprises a floor-portion or base .19,'who'se forward edge ove'rliesthe tie-:rod 12 of the typewriter. At its rear portion `the jig-frameis bent upwardly and-rearwardly at =20to form a flange 21, upon whose under side are secured guide-blocks 22 by means of screws 23. These guide-blocks are dovetailed to the flange at 24 and have transverse bores 25 t0 fit upon the cylindrical carriage-track rod 11 for securing accuracy oflocation of the jig in the typewriting machine. The bores or openings 25 are cut away at 26 and the jig may be swung up until the openings 25 clear the ribs 27, whereby the way-rod or track is secured to the tops of posts 28 that rise fromthe frame 10. The jig may therefore be readily slipped upon the carriage way-rod 11 and slidden along to a central position in the machine.

For aid in locating the jig centrally of the machine, there is provided a master typebar 29 having a master type 30 thereon and swinging up around the fulcrum-rod 15 and entering the center type-guide 17. When the master type is in its elevated position, Figure 1, the jig may be slidden toward the right along the way-rod 11, until a jig-centering gage 31 touches the side of the master type 30. The dimensions of the latter correspond eXactly with those of the types which are to be soldered upon the type-bars of the machine. The position of the master type laterally of the machine is governed by the center guide 17, into which the master type-bar 29 fits without lateral play.

This jig-centering gage 31 is to be subsequently used as a gage against which to set the printing types one by one preparatory to receiving their respective type-bars for soldering. The gage at its working face is recessed at 32, between its top and bottom, so that each type is gaged by its top and bottom face portions, Figure 5, thus conducing to accuracy.

The jig should be not only centered but also provided with a firm support, so that it cannot rock or stir. Tn the front of the ioor 19 are provided adjustable feet for the gage, in the form of screws 33 threaded down through the fioor near its front edge and resting upon the cross-bar 12 of the typewriterframe; these screws 33 being at opposite sides.

of the jig. By their adjustment up and down, the gage is made to rest levelly` and solidly upon the cross-bar 12; whereupon the front portion of the `gage is fastened down by screws 34, which entend down through open slots 35 in the sides of the floor 19 and are threaded at 36 into holes usually provided in the cross-bar 12.

Screws 37 may be threaded through the blocks 22 to engage the way-rod 11 on its under side, Figure 1, to draw 4the rear end of the gage-fixture accurately and firmly down upon the way-rod. By this device the gage is prevented from slipping rearwardly, and from yielding or springing at any point it is held firmly in central position, with its floor in level condition. This result is quickly secured by simple means demanding but little skill or training. j

Said top side gage 31 is fastened by a screw 33 upon a large vertical plate or flat platen 39 which is erected above the floor 19 of the jig; said plate 39 being supported on the floor by means of a base 40. This base 40 is movable for the purpose of adjusting the plate 39 forwardly and backwardly, since it is used as a face-gaging platen for all the types.

When the types one by one are placed on the gage, they are set towards the left, against the side gage 31, and rearwardly against the type-face-gage-plate 39; and it is therefore necessary for the gage 39 to be located with exactitude at the proper point, considered fore and aft of the machine. This adjustment of the type-face gage-plate 39 is permitted by moving the base 40 forwardly or backwardly, and securing'it by means of a screw 41, whose head 42 is provided with a handle 43 for speedy operation, and bears down upon a washer 44 that is inserted between the head 42 and the base 40.

The fioor 19 may be reinforced by adding thereto a nut 45, which may be soldered or brazed at 46 to the bottom of the ioor, so as to give the screw 41 a longer bearing for efficiency.

The base 40 has a clearance slot 47 for the screw 41, and it also has corresponding guideslots 43, 49, which guide dowel-pins 50 that are riveted to the base 40 and extend down into the slots.

By this means it is insured that the base 40, together with the type-face gage 39, shall be adjusted always at right angles to the way-rod 11, thus conducing to evenness of the type-impressions upon the work-sheet when placed upon the platen of the finished machine. The face-plate being parallel with the way-rod 11, and the platen being also parallel with 11, it is insured that any type which is gaged by means of said face-plate 39 and then soldered, must strike evenly upon the platen, thus avoiding liability of one side edge of the type printing more heavily than the other side edge.

The slots 47, 48, 49 permit forward and rearward adjustmentof the typeface-gage 39. The position to which said gage can be adjusted is determined mechanically7 by the contact of the master type 30 with the typebar anvil or stop-ring 51 formed upon the front of the member 13 to serve to arrest the type-bars at the conclusion of their printing strokes.v

It will be seen at Figure 1 that when the master type-bar rests against the machinestop 51 its master type 30 occupies exactly the right position in respect to the platen that is subsequently to be added to the typewriting machine; and it results that when the type-face-gage 39 is set up against the master lou type 30,` and .there fastened, Lall ltypes that are subsequently set against saidtype-face-gage will-likewise be found exactly in correct'lrelationship 'to the platen.

In order to compensatefor slight inaccuracies arising from manufacture of the jig, or from accidental warping fthereof, or from other causes, the type-,face-gage 39 is provided with means whereby it maybe canted a little forwardly or backwardly, so thatl the dummy or master type 30 shall rest squarely against -said face. This tilting adjustment is controlled by means of a pair ofscrews 52, Figures 5 and 6, threadedforwardly through a vertical flange 53 that is bent 4up fromthe adjustable base 40 and aV screw 54 threaded through the bottom of said flange 53. Vhen the screw 54; is rotated, 4its end bears against the rear side of saidl flange 53 and rocks the bottom of the type-face-gage-plate 39 rearwardly, and the top thereof forwardly. Said gage-plate may be held'against the rear face of the'flange 53 by means of said screws 52,

Fi ure6 which ma be loose during the adg 1 y 1 e justment, and mayy then be tigntened, so as to hold the tilted plate 39 at its proper adjustlnent upon the supporting flange 53.

From the foregoing, it will ,be seen that said plate39 mayfbe carried bodily. forward or backward upon its base 40, and that it may also be tilted forwardly or baclwardly, with the result that the gage-plate maybe brought perfectlyl against the master type'30, whose position is determined by means of the .stop 51 in the typewriting machine. For further accuracy, the gage-plate 39 vmay be doweled at 55, 56 to the supportingflange 53, Figure 5; and the side type-gage 31 maybe dowelec at 57 to the type-face-gage-plate 39., i

After thus adjusting the-side gage andithe face gage to the master type 30, it remains to adjust the bottom gage 58 to saidmaster type.

This is a thin razor-edge gage, whicl1,because-VV 1. ,bar and filling the slot-,and permanently atr of its thinness, is mounted upon a carrierblock 59 that is guided upand down in avertical slot 60 formed in the stationary flange 53 of the main bracket'or base Ll0; said. slot 60 being central ofthe machine. The carrierblock 59 may be made of copper, and the gage 58 may be made of a thin film of Steeb-,having side flanges 61 bent over said block and. fastened thereto, Figure 3.

The bottomgage 58, whichlies in contact with the type-face gage-plate 39, is sliddenv up againstthebottom edge 62 of the mastery type-block 30, and` then secured-by means of` a thumb-screw 63, .to serve as a bottom gagev for types preparatory to soldering. The stem of the screw 63 plays upland downin 'a vertical slot 64 in the type-face. gage-plate 39.

Therazor-edge gage 58 contacts with the type` only at the corner which occurs between the shoulder of the ftypefand ,the face thereof, so that all types can be brought accurately to the correct `vertical position, l notwithstanding v, somel1 variation in the bevelsof the shoulders `,of thetypes.

After the jig has been, introduced in the machine, and the various gages have been accurately v adjusted-and secured and everything fastened, the master type-bar 29 may be ldetachedfrom the typewriter, and, one by i clamp 65, which is shown withdrawn at Figvure, and in type-clamping position at Figure'2. The nose of the Aclamp may be held i against the type by means of a spring 66. The

type-clamp is in the form of a slide that is mounted :by means of shoulder-screws 67, 68 in horizontal guiding slots 69 in the type-face gage-plate 39.

Withdrawal-of the clamp fromf-the type maybe effected by depressing a handle 70, Figure 5,v to rotate a cam 7l, which is pivoted at 72- uponthe slide, said cam having a flat portion or dwell l73 to detain the clamp in open position. -After'the type is'inserted, the

handle is lifted, and the nose of the cam` passes down` along the edge of the plate 39, and the spring-66 /forcestlie-.type to the left against the `side gage 3l, and holds itduring the soldering operation.

lt will be perceived that after the removal of the 1nastertype-bar29,with its type30 fast thereto, a printing-type Tl maybe set against the sidegage v31,*the bottom gage 58, Y

and the type-face gage 39, and there heldby the clamp 65 and spring-66, upon-depressing the clamp-handle 70. While the type 'Z4 is so held, one of the type-barsl 14 is swung yup, .Y

and its tip is inserted into the usual slot 7 5 formedrin the type vand while the `type-.ba-r-is yheld back against the stop-ring 51, andthe type is held against all the gages -by the Clamp 65, solder is droppedy into theslot 75 in the type,` surrounding the tip of the typetachingthe type to the type-bar.

The type-barsare apt to vary according to llO inequalities of manufacture, or to becomeslightly bent and-twisted in handling, before insertionin the typeW-riting machine ,.so that the tip of the type-bar is apt to stand-in someor the other, or-twisted a little. however, does not partake of this'fault in the-type-banbecause the slot` in the type is made -a littlel oversize, so that `the'type-bar Vwhat inaccurate position, Ainclined to one sidey The-type, l

can enter the slot even thoughthefsidefaces of the type-bar arenot .parallel with the side .faces of the slot. Vhatever the fault of thel type-bar, and. however it stands in the typeslot, the solde-r fills up all of the space between the type-bar and the type, so that the effect of the fault of the type-bar is nullified, .and`

the type-bar is thereafter bound to swing-the type 'back to its originalgaged position, not- .,withstanding the aforesaid slight faults ofuloA i the type-bar. Hence the alignment of the types is rendered permanently uniform and accurate, and the character of the type-impressions is rendered perfect.

In a feW cases, Where it is impracticable to use the bottom gage 58, there may be employed an inverted top gage 7 6, While the bottom gage 58 may be loosened and slidden down out of Working position. The inverted gage 76 may be similar to 58, and similarly mounted upon a slide-block 77, guided in a plate 7 8 that is fixed upon a front vertical surface of the type-face gage-plate 39. The upper block 77 has a fastening device in the form of a thumb-screw 79 similar to 63. The master type-bar 29, 30 is first inserted and moved to the gaging position at Figure l, and then upper gage 7 6 is dropped into engagement With the corner formed by the top line of the type With the top bevel shoulder of the type, as shown at the left of Figure 4. The stem of the screw 79 plays up and down in a vertical slot 79a in the type-face gageplate 39.

It Will be noted that the machine-frame being assembled for a complete typewriter has a carriage-rail and a type-bar segment permanently secured thereto; that the soldering appliance is secured to the carriage-rail and the segment which may or may not have a complete series of type-bars assembled thereto; and that the soldering of the type-blocks upon their bars in exact printing position upon a platen-face indicating the platen-face of a cylindrical platen to be subsequently assembled, is a iinal alignment of the type-faces and not an alignment that must be checked up and corrected, When the segment of soldered type-bars is assembled to the machineframe, as heretofore.

Variations may be resorted to Within the scope of the invention, `and portions of the improvements may be used Without others.
