SHUTTER AND SHUTTER BED FOR PATTERN SELECTING MECHANISM Filed Dec. 30, 1932 3 Sheets-Sheet 5 Patented May 15, 1934 UNITED STATES PATENT OFFICE SHUTTER AND SHUTTER BED FOR PATTERN SELECTING MECHANISM Application December 30, 1932, Serial No. 649,574

19 Claims.

My invention relates to improvements in shutters and shutter beds for pattern selecting mechanism and has for one object to provide a new and improved form of shutter and a new and improved form of bed mounted therein and associated parts whereby the shutter may be positioned, actuated and controlled. Another object of the invention is to provide a shutter which will be cheap, light, stiff and strong. Another object is to provide a compact yielding shutter return mechanism. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein- Figure 1 is a diagrammatic side elevation of the machine showing the position occupied by the shutter bed;

Figure 2 is a section along the line 22 of Figure 1 with parts omitted and parts broken away showing the shutter bed in plan;

Figure 3 is a section along the line 33 of Figure 2 showing the shutters in section;

Figure 4 is a section along the line 4-4 of Figure 2 showing the shutter in section;

Figure 5 is a section along the line 55 of Figure 3 through the shutter bed;

Figure 6 is a plan view of the shutter;

Figure '7 is a side elevation of a shutter;

Figure 8 is a section along the line 8-8 of Figure 6.

Like parts are indicated by like characters throughout the specification and drawings.

It will be understood that the apparatus which forms the basis for this application is merely one of the elements in a complicated pattern selecting mechanism adapted for use in connection with type casting and type setting machines but owing to the complication of the device and the large number of parts involved, I have illustrated in this case only those parts of the mechanism which form the subject matter of this present invention showing them in their proper setting but not illustrating in detail the remaining parts.

It will be understood that the mechanism I am dealing with is a complete operating unit in itself but serves as one unit in a chain of mechanisms. I have illustrated it as part of a type casting machine though obviously the selecting mechanism might be used in connection with type setting machines or in other machines where it was desired to select certain elements, form a pattern, or to designate certain specific parts or cause certain specific elements to move or to remain at rest.

The machine, of course, comprises a rigid framework A A uprights A A a lower cross member A and an upper cross member A J oining the upper and lower cross members A A and supported on them is a typewriter and shutter bed A which in working position is inclined to the horizontal as indicated. Projecting above this bed, preferably mounted on it and preferably integral with it is a generally horizontal typewriter platform A The typewriter bed has at either side downwardly extended flanges A upon which the shutters are pivoted and which flanges form with the typewriter bed, the shutter bed, and also form in effect a closure or housing for the selecting mechanism.

Pivoted on the flanges A are a series of selectter channel is relatively wide and has two flanges, 807

one wider than the other, the shorter one having a very gradual curvature so as to provide a curved contact face. Welded or otherwise attached to each shutter at some point between its ends is a shutter arm C it being understood that since there are a plurality of these shutters, the shutter arms for successive shutters are spaced along the shutter so as to be generally in line with the mechanism controlling that individual shutter. tween a perforation on the shutter arm and the free end of one of the bell crank levers. C is a resistance spring provided for the purpose of resisting rotation of the shutter in a counter clockwise direction as shown in Figure 5 under the 975? influence of the tension rod C It will be understood, of course, that the pull rods 0 are of varying length because the bell crank levers are on the same axis and the shutters are spaced along the shutter bed, hence a 109 longer or shorter member 0 is needed to connect each bell crank lever with its associated shutter. The spring C comprises any suitable type of tension spring. It is anchored at one end on the shutter lever C and at the other end on an anchorage frame C This frame is mounted on the shutter bed above the plane of the shutters.

This frame has a diagonal cross member (3 extending clear across the machine, a diagonal C is a tension rod be- 9 cross member C extending from one side to the end of the frame and a diagonal member C extending inwardly from the end far enough so that a line parallel with the axis of the machine intersects the inner end of the member C the outer end of the member C These three frame abutment members C C C are needed so as to have space for the springs and pull rods for the various shutters as if these members extended across the machine, the springs and pull rods would be so crowded as to be inoperative. The spring associated with the members C and C are merely tension springs. One end of the structure is fastened to the member, the other end is fastened to the shutter. This situation, however, is different with respect to the parts associated with the members C because the shutters come clear to the end of the frame. It would be necessary in order to get a direct pull for the member C to be extended forwardly beyond the frame, hence the member C which is parallel with the member 0 and that member carries rigidly mounted thereon an abutment for the springs C which springs instead of being directly connected to the shutters are connected to eyes C on push rods C which push rods terminate at one end on the shutter arms 0*, at the other end slide in the guide C so that the tension of the springs C associated with the member C instead of acting directly in tension on the shutters act in tension on the eyelets C and this tension is transmitted to pressure applied through the push rods C It will be understood that the rotation of the individual shutters in the shutter bed is one step in the connection between the typewriter and the pattern mechanism. The details of the typewriter and typewriter connection are not shown or discussed in this application, being shown in co-pending cases, because they form no part of the invention herein claimed. The same is true of the connections or chain of connections from the shutter bed onto the pattern mechanism. It will be understood, of course, that this particular shutter bed and shutter mechanism can be used with a multiplicity of different connections between the typewriter and it and between it and the pattern mechanism and that the elements herein shown, described and claimed are a uni tary element in and may be replaced as a unit in connection with applicants pattern selecting device and applicants type casting and type setting machine.
