CONNEGTINGROD FGR TYPE VVWTERS.

SPECIFICATION forming part of Letters Patent No. 744,931, dated November 24, 1903.

Application filed April 1, 1903. fierial No. 150,616. (No model.)

To all whom it may concern:

Be it known that 1, JOHN E. MOLLE, a citizen of the United States, residing at Sturgeon Bay, in the county of Door and State of WVisconsin, have invented a new and useful Connesting-Rod for Type-Writers, of which the following is a specification.

This invention relates to certain improvements in type-writers, and more particularly to a connecting-rod for connecting the keylevers and type-bars of type-writers and similar machines.

The primary object of the invention is to provide a detachable connection betwen the type-bars and key-levers, so as to permit the connecting-rod to be easily and readily removed to facilitate the repairing of the keylevers and type-bars without dismantling the entire machine.

. A secondary object of the invention is to provide a simple, inexpensive, and efficient device of this character, the connecting-rod being formed of a continuous piece of wire provided at one end with a type-bar-engaging hook, the opposite end of the rod being formed with coincident loops or eyes adapted to receive a spring-actuated rod or pin, which acts in conjunction with a hook on the lower end of the rod to engage the key-bar and detaclr ably secure the same to the connecting-rod. The invention consists in the construction and novel combination and arrangement of. parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportion, and minor details of construction may be resorted. to without departing from the spirit or'sacrificing any of the advantages of this invention.

In the accompanying drawings, Figure 1 is a side elevation of aportion of a type-writing machine, illustrating a connecting-rod 0011- structed in accordance with my invention applied thereto. Fig. 2 is a perspective View of the connecting-rod detached. Fig. 3 is a side elevation of the sliding pin or bolt detached. Fig. dis a similar view of the spring. Fig. 5 is an enlarged detail view illustrating in side elevation the manner of attaching the spring to the sliding pin or bolt; and Fig. 6 is a side elevatiompartlyin section, showing a different manner of attaching the connecting-rod to the key-lever.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings.

1 designates a portion of a type-writing machine of the ordinary form and construction provided with the usual type-bars 2 and keylevers 3. The connecting-rod 4: is preferably formed of a continuous piece of metal or other suitable material, preferably wire, one end of which is bent to form a hook 5, which engages an opening in the end of the type-bar, the opposite end of the rod being bent to form outwardly-extending coincident eyes or loops 6, the end of the wire after the lower eye or loop is formed being bent to form a substantially rectangular hook 7, adapted to engage the key-lever proper or a strap or stirrup 8, secured in any suitable manner to the key-lever 3. Slidably mounted in the loops or eyes 6 is a rigid pin or bolt 9, provided with a coil-spring 10, one end of which bears against the upper eye or loop, the opposite end of the spring engaging the fiat roughened faces of an enlargement 11, formed on the pin at apoint adjacent its lower end. The spring 10 occupies the entire space between the upper and lower eyes or loops, the coils thereof forming a roughened surface and permitting the pin to be easily grasped by the hand and retracted when it is desired to connect to or disconnect the rod from the keylever.

In applying the connecting-rod to a type writing machine the hooked end 5 of the rod is introduced in the opening in the type-bar, the spring-pin retracted, and the rectangular hook 7 passed through the strap or stirrup on the key-lever, after which the pin is released, the spring forcing the pin to its seat and locking the connecting-rod to the stirrup. It is obvious that by retracting the pin the lower end of the rod may be disconnected from the stirrup and the hook on the upper end of the rod disengaged from the type-bar, permitting the type-bar and key-lever being removed and repaired when worn or broken without dismantling the machine, as is at present necessary Where the connecting-rod is permanently connected to the type-bar and keylever, respectively.

and inexpensive connecting-rod capable of being quickly applied in position and easily detached and in which the spring not only serves to return the pin to its normal position after being retracted, but also forms a roughened surface, permitting the same to be easily grasped by the hand.

Having thus described the invention, what I claim, and desire to secure by Letters Patent, is-

1. A connecting-rod having oppositely-disposed terminal hooks, and-a rigid locking-pin slidably mounted on the rod and adapted to engage one of said hooks.

2. A connecting-rod having oppositely-disposed terminal hooks, a rigid lockingpin slidably mounted on the rod and adapted to engage one of said hooks, and a spring carried by the locking-pin.

3. A connecting-rod provided with a terminal hook, coincident eyes or loops formed in the rod, and a spring-actuated locking-pin slidably mounted in the eyes or loops and cooperating with the hooked end of the rod.

4. A connecting-rod having oppositely-disposed terminal hooks and provided with intermedi'ate coincident eyes or loops, a pin slidably mounted in the eyes or loops and adapted to cooperate with one of the terminal hooks, and a spring carried by said pin.

5. A connecting-rod formed of a continuous piece of material one end of which is bent to form a hook, the opposite end of the rod being provided with coincident eyes or loops terminating in a hooked end portion, a pin slidable in the eyes or loops and a coiled spring surrounding the pin and interposed between the eyes or loops.

6. A connecting-rod provided with an up per and lower hooked end portion, outwardlyextending eyes or loops on the rod, a pin provided with an enlargement having a roughened surface slidably mounted in the eyes or loops and adapted to cooperate with one of the hooked end portions of the rod, and a coiled spring surrounding the pin, one end of said spring bearing against one of the eyes or loops, the opposite end of the spring engaging the roughened surfaces of the enlargement.

7. A connecting-rod havingengaging means at one end, a hook at the opposite end of said rod, and a rigid locking-pin slidably mounted on the rod and adapted to engage the hooked end thereof.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
