' typewriter which is of a novel construction adapting it to be readily collapsed into a small compact form, such that it can be conveniently shipped and carried from place to place.

In a copending application Serial No. 658,153, filed Nov. 2, 1911, is disclosed a col lapsib le front strike typewriting machine equipped with the various devices necessary for it to perform all of the functions demanded 0f the larger and more expensive typewriters of the most approved and up-todate design. The present application shows another way of accomplishing substantially like results, in which, however, the collapsible frame is composed of slidably connected parts or sections,instead of the hinged construction disclosed in said application. The

machine herein'described, when collapsed, is materially shorter from front to rear, but is somewhat higher, than said other machine. In this application is also shown a case shifting mechanism and space -key mechanism which differ from the corresponding mechanism shown in said prior application, but the remaining features of said other machine can be used in the present machine practically without change.

This application filed January 17, Serial No. 125,703.

Fig. 4 is a fragmentary plan thereof.

Fig. 5 is a transverse sectional elevation in line VV, Fig. 1.

Like reference characters refer to like parts in the several figures.

'A represents the platen, B the platen carriage, b the ball bearing guide on which the carriage travels transversely of the machine. C one of the type bars, D the finger keys for actuating the type bars, and E the universal bar. These parts. as well as all'the devices supported bv the carriage, the carriage cscapement, ribbon operating mechanisms and other parts which are shown in said prior applicatiombut are not shown herein. as

they are not necessary to an understaluling of this invention, can be. and preferably are, except as hereinafter explained. constructed and arranged as described in said application. The type bars are suitably pivoted to swing upwardly and rearwardly to the platen on a segment 0 which is supported by a shift frame C which is movable for placing any one of the three sets of characters on the type bars in printing relation to the platen. Each of the finger keys I) is supported by a pair of key levers (Z (7 which are connected by links and d to one of the type bars. The universal bar E consists of a curved bar arranged to be struck by the type bars as they approach the platen. This bar is supported by rearwardly extending arms 6 pivoted to rock arms 6 and actuates the carriage escapement and ribbon vibrating. mechanism (not shown), as explained in said prior application.

As in said other machine. the type bars C and their key actions are mounted on a base or stationary frame part F, while the carriage is supported by a frame. or frame part G, which is movable relative to the base or stationary part of the frame and the parts supported thereby for collapsing the machine. The movable frame G-is. howe er.

slidably connected to the. base F. instead of v being hinged thereto.

In the'construction shown, the base or stationary frame-part consists of parallel side plates 7 f and a front cross bar made in one integral casting. The side plates are also connected lay-a detachable crossbar f upon which the key levers 03 d are fulcrumed. Each side plate is provided with two sockets to receive rubbersupporting feet f for the machine, and has two inwardly projecting bosses f to receive the pivots on which the shift frame G is mounted, and the plate also has a similar boss f to support the pivot for the shift leversr The movable frame-part also preferably consists of a substantially U-shaped, or three sided casting, having parallel side plates 9 5/ connected near their rear ends by a cross bar 9 This frame is wlde F than and straddles the base F, the overlapping side plates of the two frames being connected by a pair of Screws H passing through slots h in the front ends of the plates 9 g into the central portions of the plates 7 f, and thumb screws H passing through slots 12, in the rear portions of the plates 9 9 into the rear ends of the plates 1 f. The plates f f are made with bosses he in which the holes for the screws are located and which serve to space the side plates 9 g a short distance away from the plates f f.- The ends of these bosses and the inner faces of the side plates 9 g. are machined to produce a sliding fit between the movable and stationary frame parts. The, screws H are shouldered so as to hold the frame parts together without objectionable loose'ness and yet permit a free movement of the movable which arem'ot'so light.

frame part G, and the thumb screws H have shouldersadapted to fit into counterbored' seats k in the ends of the slots h for positively locking the frame parts together against movement in any direction when the thumb screws are screwed in tightly. To collapse the machine, the thumb screws are unscrewed enough to withdraw their shoulders from the seats h in the front ends of the slots h, and then the movable frame part G can be moved forwardly and downwardly to the position shown in Fig. 2. If the machine is to be transported to another place, the thumb screws should be screwed home to enter their shoulders into the seats in the rear ends of the slots h. In order to make the machine ready for use, the reverse of this operation is all that is required. By curving the ends of the slots h upwardly, as shown, the movable frame G will retain its position by gravity when the thumb screws are not screwed into locking position. By making the slots 7L h inclined the movable frame is caused to move both downwardly and forwardly when the machine is collapsed and by differently inclining the slots, as shewn,-the platen, which is the highest part ofthe machine, is lowered a greater distance than the parts in front thereof,

VAsshowm the screws H H are seated in the side plates of the base F and the slots h it formed in the side plates of the movable frame G, but this arrangement could" be reversed, or one pair of the slots and one pair screws could be arranged in the side plates of each of the frame parts.

Obviously, a horizontal movement of the movable frame could be obtained by the use of horizontal slots, or a vertical movement,

by the use of vertical slots, but thedescribed arrangement of the slots enables the machine to be reduced both in height and 4 lower arms I being rigidly secured at their front ends to a rock shaft '4' near its ends and each of the upper arms I being pivoted at its front end to the boss f on the adjacent side plate of the base F. But, in the present construction the upper arms I, the upper front ends of the shift frame and also the rear ends of the rods 2' that support the type bar basket (not shownl are preferably located lower than shown in said prior application to allow the rear end of the movable frame G to drop lower down when the machine is collapsed.

For operating the shift frame the lower supporting arm I at the left hand side of the machine is made in. the form of a bell crank, or with an upright-part having at oneside an anti'friction roller 70 which projects into oppositely inclined cam slots or openings 70 70 in two shift levers K K ,These levers are arranged side by side, being suitably spaced apart and fulcrumed at their rear ends on a pivot 70 seated in the lug f on the side of thel'base F. When the lever K is depressed the roller 7c is forced rearwardly and the shift frame lowered, and when the lever K is depressed the roller is forced forwardly and 'the shift frame raised. When the levers are in the normal position shown, the cams 7c 70 engage the roller at opposite sides and positively hold it in its central position against movement in either direction, thus locking the shift frame and to guard against wear that might permit vibration of the shift frame as it returns to the normal position from either of its shifted positions, the cam slots are curved at their lower ends to fit the roller for a considerable part of its circumference. In order to make this locking action just right, the pivotal axes of the shift levers K K and of the arm I are located on lines which cross igaaae'ai when it is in its normal position, and to'insure the shift frame beingheld perfectly stationary when in either of its shifted pos1t1ons,the upper ends of the cam slots are made with l and 3.

Suitable springs lo 10'' serve to retractthe is pivoted between its ends on the bar f.

A rod or link Z connects the rear end of its lever to a spacing lever Z which is pivoted preferably between the two central type bars on the fulcrum wire for the type bars. When the space key is depressed the spacinglever 1* is caused to strike the universal bar and trip the escapement just as wlien the type bars strike the universal bar. The space lever Z is only of suflicient length to strike the universal bar when the segment is in its lowest position, and it normally lies horizontally so as to be under the cross bar 9 of the movable frame G when the machine is collapsed. 1

M, Fig. 2, indicates the line space lever. It is not.necessary for this lever to be jointed as described in said application, and the le- Yer shown is rigid.

N represents supports for the ribbon spools formed by inwardly projecting portions of the side plates of the movable frame G.

t will be observed that one of the features of importance in this machine is that during the act of slidably compacting as well as the actof extending the frame members the operating elements carried thereby are not inverted, .but on the contrary are maintained a inan upright or operative position so that by simply extending the frame the group of elements carried by one member thereof is brought into cooperative position with respect to the elements on theother member,

thereby contributing materially to simplicity of construction and accuracy of operation.
