TYPE-BAR GUIDE FOR TYPE-WRITERS OR LIKE MACHINES.

SPECIFICATION formingpart of Letters Patent No. 735,152, dated August 4, 1903.

Application filed March 13, 1903. Serial No. 147,577. (No model) To all whom it Huey concern:

Be it known that 1, CHARLES DE Los RICE, a citizen of the United States, and a resident of Hartford, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Type-Bar Guides for Type-VVriters or Like Machines, of which the following is a specification.

My invention relates to type-writers and like machines, and particularly to the means employed for guiding the type-bar adjacent to the printingpoint, and has for its object to provide a simple construction of the aboveindicated character which will be capable of ready adjustment, so that the type-bars may be correctly guided to the printing-point.

I so construct my improved guide that the adjustment may be made when the machine is first assembled and may be corrected, if necessary, at any time during the life of the machine.

One form of my invention will now be described with reference to the accompanying drawings, and the novel features will then be pointed out in the appended claims.

Figure l is a front elevation of the type-barcarrying segment of a type-writing machine, together with my improved type-bar guide attached thereto. Figs. 2, 3, and 4 are sectional views taken on the lines 2 2, 3 3, and 4c 4, respectively, of Fig. 1. Fig. 5 isa crosssection on line 5 5 of Fig. 2. Fig. 6 is a detail face view of a nut employed in my invention, and Fig. 7 isa plan of the guide and segment.

A indicates the segment, on which the typebars are fulcru med in any approved manner.

B is the type-bar guide, which is located at the top edge of the segment A and which at its upper end is formed with the forwardlyprojecting arms B, the adjacent surfaces of which flare forwardly, so as to form a guide for the type-bar toward the printing-point. It will be understood that the printing-point is in the central plane indicated by the line 3 3 in Fig. 1. The arms B project from the upper ends of fork members B which are separated from each other by a vertical slit B preferably provided at its lower end and also, if desired, near its upper end with enlargements B. By this construction the fork members B are given elasticity, so that they will have a tendency to move toward each other. The fork members B and guide members B, which are thus movable transversely in relation to each other, may be spread apart by means of an expanding-screw C, which engages both members and has a conical head 0, so that as the screw is screwed in the fork members B will be moved farther apart. To lock the fork members in their adjusted position and to assist the inward movement produced by their resiliency, I provide a screw D, which connects the fork members B transversely, as shown best in Fig. 5. It will be understoood that this conmeeting-screw D extends across the slot B While the expanding-screw C extends into the said slot.

7 The means so far described enable the width of the slot B or, in other words, the distance between the guide-arms B to be adjusted. In order to enable the guide-arms B to be leveled, I provide the following arrangement: The body B of the guide has at a distance below the vertical slot B two horizontal slots B provided at their inner ends with enlargement B Into these slots are adapted to fit screws E, having conical heads E and also lugs F,projected from nuts F, into which the said screws E are adapted to screw. The opposing surfaces of the lugs are beveled to correspond to the conical face of the screw-head. The body of the nut is received within a slot or recess A of the segment- A. It will be understood that the lugs F prevent the nuts Ffrom turning relatively to the guide-body B. Thus when the screw E is turned it will have a tendency to crowd the upper wall of the slot B upward, since the lower portion of the body B is rigidly secured to the segment A, as by screws G.

The slots B give a resiliency'to the portions B located above them, and these portions practically form movable arms capable of a movement which may be described as approximately a pivotal movement the center of which is adjacent to the intersection of the lines 3 3 and at 4 in Fig. 1.

Now supposing the left-hand screw E is released and the right-hand screw E is tightened,the entire portion of the-guide which is above the slots B will be swung in the direction of the arrow in Fig. 1, thus changing the position of the top line of the guide relatively to a horizontal plane. It will therefore be obvious that by releasing one of the screws E and tightening the other the type bar guide may be leveled, so that the slot B will be exactly vertical and the upper faces of the arms B exactly horizontal.

What I claim as new, and desire to secure by Letters Patent, is

1. A type-bar guide comprising two guide members movable toward and from each other, an expanding-screw having a flaring portion adapted to engage both of said members, and another screw connecting said members transversely.

2. A type-bar guide comprising two resilient guide members movable toward and from each other, and having a tendency to move toward each other, and an expanding-screw arranged between said members and engaging both of them.

3. A type-bar guide comprising two resilient guide members having a tendency to move toward each other, an expanding-screw arranged between said guide members and adapted to spread them apart, and another screw connecting said guide members transversely and adapted to hold them in their adjusted position.

4. A type-bar guide comprising guide members movable toward and from each other, an adjusting-screw located between said members and controlling the distance between them, and means for holding the guide members in their adjusted position.

5. A type-bar guide comprising resilient guide members,-an expanding-screw located between said members and arranged to spread them apart against their resiliency, and another screw connecting said members transversely to hold them in their adjusted position.

6. Atype-barguidecomprisingastationary guide-body, a guide proper movably connected therewith, and adjusting means for rigidly connecting said guide-body with the guide proper, so that normally the guide proper will. be stationary and rigid with the guide-body.

7. A type-bar guide comprising a stationary body portion and a guide portion proper movablyconnected with said body portion to swing so as to allow the guide proper to be leveled.

8. A type-bar guide comprising a stationary body portion, a guide portion movably connected with said body portion, and expanding-screws arranged between said portions to adjust the guide portion relatively to the body portion.

9. Atype-bar guide comprisingastationary body portion, a guide portion connected with said body portion and having arms extending at a slight distance from adjacent edges of the body portion, forming slots therewith, and adj usting-screws arranged in said slots.

10. A type-bar guide provided with a vertical slot, whereby two adjacent resilient guide members are formed, and also provided with horizontal slots whereby a body portion is separated from a guide portion yieldingly connected with said body portion, and means arranged in the said slots for adjusting the distance between the guide members, and for adjusting the guide portion relatively to the body portion.

11. A type-bar guide having two members movable toward and from each other and separated by a slot, a nut provided with lugs projecting into said slot to prevent the not from turning, and an expanding-screw fitting into said nut and in engagement with said members to adjust the distance between them.

12. The combination with the type-bar segment of a type-writing machine, or the like, said segment having recesses adjacent to the printing-point, of a type-bar guide having a body portion secured to the segment below said recesses, and a guide portion arranged above said body portion and separated therefrom by horizontal slots, nuts located in said recesses of the segment and provided with lugs projecting into said slots, and expanding-screws arranged to fit the said nuts and to engage the walls of said slots to adjust the guide portion relatively to the body portion.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
