NEW JERSEY, a conronariou or NEW. JERSEY.

TYPE-VIRITING MACHINE.

To all whom it may concern: 1

Be it known that I, OSCAR \VooDwAnn,

citizen of the United States, and resident of Montclair, in the'county of Essex and State pf New Jersey, have invented certain new and useful Improvements in Type-VVriting.

Machines, of which the following is a specification.

,Myinvention relates to typewriting machines and more particularly to the con- 'struction of hangers for said machines, and

to means for securing said hangers in place.

,In the present instance the hangers are ndividual hangers may be readily mounted shown as type bar hangers.

The main object of the invention is to provide a simple and eflicient construction of the character'specified in which the inof parts and combinations of devices to be hereinafter described and claimed.

'Inthe accompanying drawings 1n which like reference characters indicate corres onding parts in the various views, Figure I .1 is a skeletonized side view, partly in section, showing a type action and a diagrammatic illustration of a platen with the feature of my invention embodied therein. Figi'2 is an enlarged detail fragmentary 13 vertical sectional view of one form of construction embodying my invention. Figs. hand 4. are enlarged detail perspective views of a pair of cooperating devices by which the hanger is secured in place on'the segment. F 5 is anlenlarged detail front tail perspective views of the view showing a hanger mounted in place on the segment. Fig. 6 is an enlarged detail side elevation, partlyin section, of a modilied form of cooperating connecting devices for securing a hanger in place. Fig. 7 is an enlarged end view of one of the connecting members shown in Fig. 6. Fig. 8 is an enlarged detail perspective view of the same. Fig. 9 is a side elevation of a modified form of nut employed in connection with the companion securing member shown in Fig. 6. Fig. 10 is an end view of the same. Fig. 11 is a view corresponding to Fig." 2 but showing a still further modification of the securing means. Figs. 12 and 13 are enlarged desecuring means disclosed in Fig. 11.

.the hanger arms may Patented Aug. 15, 1911 A key lever 1 is fulcrunied at 2 to the frame 3 of the machine and is connected to a link 1, the upper end of which is connecton trunnion-like pivots received between arms 10 of a bifurcated type bar hanger.

The outline of the type bar hanger in side' elevation is shown in Fig. 1, Whereas the shape of the hanger as viewed from the front of the machine is shown in Fig. 5 and i the hanger, as presented in this latter View, is substantially U-shaped in cross section, the arms 10 of the hanger being unitedat the looped portion thereof as at 11. The construction is such that the stem or shank 12 of the hanger is formed of two parallel side plates which are united by a screw 13 passing freely through an opening in one of the arms of the hangerand engaging at its threaded end in a tapped opening in the other hanger arm so that-an adjustment of be effected. I In the form of construction shown in Figs. 1, 2 and 3 a T-shaped head or securing member'l l is provided with a reduced cylindrical stem 15 which extends through an opening '16 in a support or type bar segment 17 and. the rear threaded end 18 of. the stem coiiperates with an open-ended nut 19 havmg members, has the stem 21 thereof of a thickness which corresponds substantiallyto the space between the arms of the stem or shank of the hanger, whereas the cross piece 22 of the T-shaped head is adapted tobear on the forward edges of the stem or shank of the hanger and to force the stem into contact with the front face of the type bar segment and thus bind the hanger in place'when' the nut 19 is' tightened. It will be understood that byproviding a construction such as that shown in which flat sides "23 of the T-shaped head cooperate with thehanger arms the securing member is prevented from turning relatively to the hanger so that a tightening of the nut 19 may the readily e'fi'ected, while the hanger is held in place, without turning thesecuring member 14. The construction shown in Figs. 6, 7, 8, 9 and 10 is-essentially the same as that shown in the preceding figures except that the stem 21 of the securing member 14 is of the same thickness throughout its length and is reeeived in an opening that corresponds to the 19", such as-that-shown in Figs. t) and 10,

may be employed in connection'wit'h the companion securing member. In the construction shown in 11, 1'3 and t3 the securing head-Il is similar to that shown in 'Fig. 4.- exeept thatthere is a'tapped opening 24 therein to receive tllethreaded end of a ,headed screw 2?. an inspection of Fig. 11 this screw is passed through an opening 27 in the segment from the rear thereof and engages at its forward threaded end in the tapped opening in the T-shaped securing head vl-l", so as to bind the type bar hanger between the securing head and segment and thus secure the hanger *in place. In all of these constructions the T-sli'aped head or securing member cooperates with the hanger in essentially the same manner and a simple and convenient securing means isprovided by which the individi-ial hangers may be readily mounted in place or detached from the, machine and by which the securing head is held against turning movement, with reference to the type bar hanger, while the other companion or cooperating threaded member is screwed in place or unscrewed to atlord an attachment or detachment of the parts. Moreover the constructions are such that the securing means for each hanger occupy no greater widtlnvise space. than the hanger itself and the nuts or securing members at the rear;

of the segment. iu'Sonle instances, are even] of less width than the width of the hangers, so that a close arrang ment of the hangers may be 'ell'ected. [*urthermore, it. will be seen that in each instance access may be had to the .--tecuring means from the rear of the segineht, which in a front-strike typ'ewriting machine of the'character shown .in Fig. 1, wherein the actuating devices are in the front of the type bar segment, this construction attords more ready access to the securing means for the hanger than would be the case if the securing serews or bolts were presented for :nljustluent from the front. of the machine.

Vhat I claim as new and desire to secure. by Letters .l.aten t, 1sz-- As .will be seen from 1. In a typewriting machine, the combination of a type bar, a hanger having a'snbstantially U-shaped shank, a segmcnthavlng a flat face against which the stern of'the.

hanger bears, a- T-shaped head, the crosspiece of which bears on the U-shaped shank of; the hanger to hold the hanger in place.

and the stem of the T-shaped head having a thickness that corresponds substantially to the distance between the arms of the shank of saidhanger, said stem having flattened faces that cooperate with the hanger to prevent a relative turning movement between the T-shaped head and the hanger, but affording a turning movement of the head relatively to the segment, and an independ: ent securing member that has a threaded connection with said head.

2. In a typewriting machine, the combina-' tion of abifurcated hanger, a support there.- for, said support having an opening therethreugh and a flat fac'c against Which the stem of the hanger bears, a T-shaped secnring head adapted to he turned relatively to the segment, the stem of the T-shaped head missing through the opening formed by the bifim-ation in the hanger andlnwing a posi-Q tire connection with the hanger to prevent a relative turning movement betweenthe two and the erossn'eee of the T-shaped head ,bearing againstthe hanger to hold it in place. a second securing member, one of said securing members passing through the opening in said support, and a. threaded connection between theftwo securing members.

3. In a typewriting machine, the combination of a perforated segment, a U-shaped hanger bearing against the front facethere:

of. a type bar pivotally connected to said Signed at the borough of iwfll llttltitlll, city of New York. in the county of New York,-

and State of New York, this 17th day of May, A. T). 1909. 1
