1 Claim. 1

This invention is concerned with repair epuipment for typewriters and relates more particularly to the provision of an aligning jig for use in adjusting the carriage guide brackets of a typewriter carriage.

It is a general object of the invention to provide an aligning jig for use in assuring easy accurate adjustment of the guide means or brackets of typewriter paper carriages.

Another object of the invention is to provide a jig of the above character which can be used with Various types of typewriter guide brackets.

A further object of the invention is to provide a jig of the above character which is of a simple construction and which can be used easily in typewriter repair work.

Other objects and advantages of the invention will be apparent from the following description of certain preferred embodiments of the inven-, tion, as illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of an aligning jig with a guide member or bracket of a typewriter carriage installed therein.

Figure 2 is an end elevational view as viewed from the left of the jig in Figure 1.

Figure 3 is an end elevational view as viewed from the right of Figure 1.

Figure g is an elevational view of the jig showing a modified form of aligning bar mounted therein.

The invention as disclosed herein is particularly useful with the carriage guide brackets of the Underwood typewriter which has been selected for purpose of illustration in describing the invention.

Referring to the drawings, the aligning jig includes a base ll] of generally rectangular outline and having a longitudinal milled groove II in the upper face thereof.

Secured to the base ID or, if desired, formed integrally therewith is a pair of bearing members 12. As shown the bearing members l2 have bottom extensions IZa which seat in the milled groove II, and suitable fastening screws secure each bearing member in place. In the bearin members there is slidably mounted an aligning bar or shaft 13 which simulates the guide rail for the paper carriage of the Underwood typewriter. As shown, the bearing members I2 are slotted on one side at 1212, although they may be formed with a continuous section if desired. The bar l3 has a close but free sliding fit in the bearing members l2 so that its axial alignment 2 parallel to the length of the jig and to the milled groove ll therein is maintained accurately.

Adjacent the left end of the jig, as viewed in Figure 1, there is provided a mounting station I4 for a typewriter carriage guide bracket 16 which has a horizontal portion lBa apertured to receive securing screws ll. These screws 11 are of the same character employed in mounting the bracket 16 on the rear portion of the typewriter carriage frame so that the guide 16 is mounted on the jig in the same manner as its mounting on the carriage frame of the typewriter.

The type of guide bracket [6 selected for illustration includes a split bearing portion [6b at right angles to the base portion lEa of the bracket. The bracket [6 also has journal supports or screws I for a pair of angularly disposed guide rollers Hid which engage the guide rail of the typewriter and when accurately aligned will correspondingly engage the rail simulating member or bar I3.

In operation, a defective guide bracket l6 is secured inthe mounting station, as shown at the left end of Figure 1, with the bar 13 disengaged therefrom as shown in full lines. Then the bar l3, which simulates the carriage rail of the typewriter, is moved into engagement with the bracket IE to test the spacing and setting of the bearing portion 5b and the rollers ltd. If these are not properly aligned and adjusted with respect to the testing bar l3, the guide bracket I6 is bent until the proper adjustment is secured.

The form of guide rail, simulating member or test bar [3 shown in Figure 4 is provided with a reduced portion 13a at one end thus providing two portions of different diameter to simulate two different types of guide rails as employed in different Underwood typewriters. Either of these portions can be brought into operative relation with the mounting station [4 by end for end adjustment of the test bar I3.

While I have shown and described certain preferred embodiments of the invention, it will be apparent that the invention is capable of further variation and modification and its scope should be limited only by the scope of the claim appended hereto.

I claim:

An aligning jig for typewriter carriage guide brackets comprising a base having a longiing extensions seated in said groove, the annular bearing portions of said bearing members being disposed in axial alignment, a cylindrical bar mounted for endwise sliding movement in said bearing members and forming a guide rail simulating bar, and a mounting station formed in said groove for holding a carriage guide bracket to be tested on said base in axially aligned relation with respect to said bar, said bar being movable endwise in said bearing members to place one end thereof over said mounting station for engagement by a bracket at said station.
