Renewed October 17, 1908. Serial No. 458,802.

To all whom it"may concern:

Be it known that I, Hammer 1 i/VAGNER, a citizen of the United States, residing in Mount Vernon, in the county of Vestchestor and State of New York, have invented certain new and useful Improvements in 'lypc-lYriting Machines, of which the following a specification.

class of tabulating mechanism for typewriting and other machines in which independently d'perable denomination keys are provided, although certain features thereof may be applied to other tabulating mechanisms.

This invention is in, the nature of an improvement on the construction shown in my application No. 337,076. in which denomination keys are mounted in a row on the ends of short arms which extend forwardly from the front bar of the paper carriage, denomination stops being rigidly connected to said arms and depressible independently one of another by the keys to engage column stops provided upon the framework; said denomination stops placed side by side at letter space intervals, and each key arm with its stop arm forming a hail, the bails being of graduated sizes and nested together in two sets, and key-bearing arms diverging or fanning out at each side of the sets of stops to compensate for the greater length of the row of keys. v

According to the present invention, four single-arm stops are employed at the middle of the system, said stops having diverging forward extensions to carry their keys, means being provided for compensating for the-great extent to which the outer keys of the four are ofiset from their stop-arms. The remainin six stop-arms in the system are devoid 0" keys, but four of them are each rigidly connected by an overlying crossbar to a companionarm, the latter having a divergent key-bearing forward extension. The remainin two stop-arms are connected by rear crossars to companion arms hearing the key extensions; or in other words, these two remainin devices are in the form of bails, one arm 01? each bail bearing a key, and theother arm forming a denomination stop, and the latter is placed between the other steps in the system.

Figure 1 is a plan of the front upper portion of an Underwood. typewriting ma chine provided with the improvements.-

at the middle of the system.

Fig. 3 s an enlarged plan showing details of the four denomination stops Fig. 4' 1s a sec tional plan of the parts seen at Fig. 3. Fig. 5 is a sectional side elevation of the parts stop, and a bar on which it is revolubly mounted. Fig. 7 is a plan of the coverplate and keys. Fig. 8 is a rear perspective view of the supports of the denomination keys, and showing also in dotted lines the deprcssibl'e cover plate. Fig. 9 is a sectional rear elevation illustrating the operation of a latch to hold the cover-plate against depression.

The usual cylindrical platen is illustrated at 1. and is mounted upon a shifting platen frame, (not shown), the latter mounted in the usual manner upon av carriage comprising side bars 2 and front bar 1. The carriage is propelled by the usual spring barrel 5 and strap 0, and is provided with a letter spacing 'ack T to me h with a pinion S, the latter forming part of the usual escapement or letter-feeding mechanism. Said rack is usually provided at its end with a pair of arms 9 hinged at 10 upon the carriage frame and provided with a forwardly extending depressible arm 1.1, so that by depressing the arm. the rack may be raised clear of the pinion 8, and the carriage may run along freely under the influence of the propelling spring The carriage has a front roll 13 running upon a track. 14:.

Extending along the carriage in front of the platen is a horizontal rock shaft 15 mounted in cars 16 projecting from a bracket 17, the latter secured in any suitable manner upon the top of the front carriage bar 4. Said rock shaft extends through the end 1): 2 :of the carriage and is provided with a short arm 19, to vibrate a lever 20. and thereby depress the arm 11 of the rock frame 7, 9, and release the carriage. By means of cars 92 and screws 22 a. forwardly extending plate 523 is fixed upon said shaft. so that by depressing said plate, the carriage may be releascd. This plate is of a size to cover the denomination-stop mechanism, to protect the same from dust. These denomination keys 24, ten of which are shown, operate a set of denomination stops 25. the latter formed upon the forward ends of arms '26 and 10-- cated at letter space intervals. Each key is rigidly connected to its stop-arm, but the manner of connection is varied, as Wlll now be explained. i

The four middle stop-arms 26 the system are hinged at their rear ends upon the rod 15, and extensions 27 branch from said verge considerably from their stop-arms 26,,

and in order to compensate for this cranking (goavoid undue binding and consequent 'diflilty of operation, each ofsaidputer arms is rovided with a hub 28 of considerable ength, whereby it is mounted upon the shaft 15, so that the arm has a long bearing on said.

shaft. These hubs may touch each. other as seen at Fig. 4, and at their contiguous ends may be reduced, as at 29 to receive the narrow-hubs 30 of the two middle stop-arms 26, saidhubs 30tnrning freely upon the bearings 29 and independently of the latter, so

thatfa-nother stop may be depressed without stirring any of the others. All of the stoparms are guided, at their forward ends in a comb 31, which is in the form of a vertical flange produced by bending up the front part of the plate 17; slots 32 being cut in said flange 31 to receive said stop-arms, and the stops 25 projecting forwardly from said comb in position for pressing into line with one or more column stops 33. Upon the flanks of the middle group of four column stop-arms 26, are two groups of three stoparms 26 each, the forward ends of these stop-arms being devoid of keys.

-The outermost stop-arm is in each instance connected by a crossbar 34 to an arm 35 having a' key-bearing extension .36,

said arms 35 and 26 being rigidly connected by the bar 34 and'pre erably formed .in one piece therewith. The-next inner stop arm 26, in each instance, forms one arm of a bail, thg other arm being designated as 37 and being joined thereto by a cross-bar 38 atthe rear ends of said arms. The arm 37 carries a key-bearing extension 39. The next'inner stop arm 26, in each instance is united by a cross-bar 40 to an arm 41, carrying a key-bearing extension 42. The crossbars 40 and 37 directly-overlie certain-pf the described arms, as seen clearly at Fig. 1, and are placed one back of the other to give clearance. By this arrangement, the keys and stops are given the same regular order, as illustrated, while the outer three keys at each end of the system are given broad pivotal'bearings on the shaft 15 and consequent ease of act on; all of the arms 26*, 41f37 the paper carriage, the lightness -'ofwhich must be preserved in order to conduce tospeed of writing. In some cases, the outermost key and stop, at each endjof the system, may be omitted. The bracket 17 is formed at its rear portion with an upturned comb 43, to guide-certain of the arms.

In operation, any desired denomination key is depressed, the finger at the same time pressing down the cover-plate 23 which is open'immediately in rear of its front edge portion to receive the denomination keys, each key preferably having a separate opening 44 in the plate. The carriage is then drawn along by the spring 5 until arrested by the engagement of the depressed stop with a column sto 33 provided upon the framework. The iiey and cover-plate are then relieved of pressure and the type keys manipulated in the usual manner, types 45 striking as usual on the front of the platen 1. The depressible cover-plate 23 may be used for releasing thecarriage for ordinary purposes, as well as during the 013613131011 of tabulating as it forms a very convenient release key. The stops 33 are,adjustable along a rack 33 mounted upon the framework, as set forth in my pending application No. 315,609. Each column stop has a ball .46 pressed by a sprin 47 into either of two rooves 48 and 4?)- ormed in a rod 50 to hcfi tion, as shown atFig. 5, or in an nprlght position to permit an index 51 formed upon the'stop, to coiiperatewith the usual scale d the stop either in working posi-,

52 rovided upon the framework of the vmac ine for use with-the ordinary carriage index (not shown).

It will be seen that the keys are not only mounted at the front of the machine where they may beconveniently seen and operated, but also that they are below the line of vision. That is, the tabulating mechanism does not come between the line of-writing on the platen and the eyes of the operator.

Each of the key-bearing arms is provided on its under edge with a leaf spring 53 fixed at its rear end in said arm, and bearing at its free. forward end is a notch 54 Fig. 8, formed in the lower ends of the guiding slots 32, to restore the keys to normal positions after actuation. The cover plate is restored" by a spring 55, Fig. 1.

At the opposite end of the bar is formed another latch 60, which normally underlies an opening 61 in the plate 23, but by a movement of the bar 57 to the Fig. 8 position, it is brought beneath the body of the plate to prevent this side of the latter from being accidentally depressed; A hook 62 above the latch 56 may also be provided-to limit by the spring 25. A portion of the bar 57 may be bent rearwardly to form a flange '63,, to overlie the depressible' arms and form .a
