MOUNTING FOR ADJUSTABLE WORKING MEMBERS.

Specificationof Letters Patent.

Patented Oct. 27', 1908.

Application filed July 10, 1902, Serial No. 115,010. Renewed September 16, 1908. Serial No. 453,287.

' T 0 all whom itmay concern:

Be it known that I, Framers H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mountings for Adjustable l/Vorking Members, of which the following is a specification The present invention relates to mountings for members which although capable of being adjusted to various positions are, nevertheless, when so adjusted especially adapted to effectually resist the effect of forces tending to derange and displace them from their adjusted positions, these forces arising ordinarily from the use of the adjusted member to accomplish some definite rein other words, those forces incident to the working of the adjusted member to pro duce a designed effect.

The present invention is particularly applicable to a mounting for adjustable im pressors or type-forming instrumentalities of that class which are employed for the making of forged or wrought types; and I have in the present instance disclosed the invention as applied to the mounting of a plurality of type-forming dies grouped in sets and disposed upon a suitable carrier, serving to maintain an adjusted group in proper position despite the forces to which the working die is subjected during the type-forming operation.

In the particular embodiment which I have found to be the most advantageous each set of type-forming dies are borne by a die bar or slide, which latter is engaged with the carrier in a manner and by means embodying this invention.

In the practical use of a machine for making types and in which a plurality of sets of type-forming dies is comprised, mechanism will ordinarily be provided for shifting or adjusting that die carrier (in the event that a plurality of the same are used) upon which is mounted the particular. slide carrying the selected or chosen die. When the carrier shall have been adjusted to bring the proper die slide in line with the working or typeformingv point and the given slide shall have been furthermore shifted to bring the particular die in juxtaposition to said point, the operation of making the type may then be caused to take place through the instrumentality of appropriate mechanism.

The present improvements are especially designed to constitute an effective mounting for the adjustable die slides in those instances in which each die operates to make its type as the result of the compression of the die against the blank and of a coincident subsidiary movement in the nature of a relative alternating motion of the type making members, which combined with each other effects a working movement well calculated to completely fill the angular recesses and hair-line spaces of the die. A mechanism operating to make types in this manner is set forth in my application Serial No. 79,359, filed Oct. 21, 1901.

In consequence of a working movement of this character, that is, one compounded of a feeding movement and a to-and-fro or alternating movement, the bar or slide upon which the die is borne is subjected during the type making operation to stresses alternating from side to side and tending to displace the bar from its adjusted position, especially so when it is remembered that the slide itself is slidably engaged with the carrier on which it is mounted to permit of its longitudinal adjusting movement with reference thereto.

he present improvements are designed especially to render the shifted die bar rigid with relation to the blank while the adjusted die is operating to form a type, yet nevertheless permitting the slide to be returned to its normal or inoperative position and to be again shifted with comparative facility. To this end, the present improvements comprise a relation between relatively inclined or convergent thrust and reaction faces and substantially parallel cooperative faces especially adapted to give comparatively great rigidity to the working die bar or slide, yet permitting the slide to be readily moved longitudinally for the purpose of returning the bar or slide to its normal position and bringing another chosen or selected die to the working position.

In the drawing which accompanies the present specification, I have set forth in a general way a relation such as has been hereinbefore adverted to, such relationship existing among the surfaces of a die bar or slide mounted upon a cylindrical carrier or wheel.

In this drawing Figure 1 is mainly a sectional view on a plane transverse to the line of length of a die bar or slide, illustrating an embodiment of my present invention, the

scale being considerably enlarged as compared with the remaining figures. Fig. 2 is mainly a longitudinal section through a main carrier and shows a die bar or slide mounted in a guideway on the periphery of the carrier, the view also exhibiting in a general way the manner of and the means by which any particular die bar or slide is adjusted. Fig. 3 is a pers ective view of a die bar or slide having a con 'guration and relation of surfacessuch as set forth in Fig. 1. Fig. 4 is an elevational view illustrating in a conventional way an organization comprising a pair of main die carriers each having die bars or slides mounted thereon and in which organization the shifting movement of the main carriers to bring a die bar in line with the working point, is compounded or arises from an angular movement about the axis of each main carrier and also the movement of the pair of carriers about an axis exterior to themin other words, the figure illustrates the die head or device of a machine or mechanism of that class in which the main die carriers are each capable of an orbital and a rotary movement.

Similar characters of reference designate corresponding parts in all figures.

The present invention is especially designed to afford an effective mounting for a bar or slide designed to be adjusted in the line of its length and when it has taken an adjusted position is subject to various forces whose line of application is more or less transverse to such line of length. As an instance in which such conditions obtain, the employment of a bar or slide carrying impressors analogous to type-forming dies, matrices, etc., may be mentioned, which bars or slides upon being shifted to adjust a chosen impressor into a given point for the purpose of making upon a blank or a portion thereof a type, are, by Working movements in a plane more or less transverse to the line of length of the bars, subjected to forces and stresses of such a nature as tend to impair the proper alinement or precisionized position of the slide. I have, therefore, for the purpose of illustrating an application and an embodiment of the invention set forth in a general or conventional way, a main carrier or support B upon which are mounted a plurality of die bars or slides D, since the invention possesses an especial advantage not only for the mounting of one such bar or slide, but is particularly suited for the mounting of an assemblage or plurality thereof in close or intimate relation. Ordinarily the main carrier, such as that designated by B, is more or less cylindrical in form, although the form, construction or even employment of this particular detail of organization is in nowise concerned in the proper application of the invention. In the form of the main carrier illustrated herein,

however, the same comprises a peripheral shell 1) extending from which is a web b and having a hub b by which the carrier may be attached or supported upon a shaft, not shown. Each die slide D is so mounted as to be capable of a longitudinal or lengthwise movement for the purpose of ustment in a groove or channel, designated in a general way by C, formed in the peripheral portion of the main carrier.

Although the application of the invention is in nowise limited to the employment of any special character or construction of die, I have, for the purpose of illustration, indicated as disposed upon the outer surface of each slide a series of dies, designated without preference by E, and each adapted to form a type in cameo or relief upon the edge of a proper blank. Another feature illustrated in the drawings attached hereto relates more especially to the making of such types in typographic roximity to each other along the edge of a lank. These features pertain to walls or supplemental dies at the sides of each type-forming die for protecting (see the wall 6) the type immediately at the rear of the forming type along the edge of the blank and a supplemental or space-forming die (see a) at the opposite side of the main die designed to form in advance of the forming type a space along the blank of sufficient J extent to remove some of the stock from the field of the type next to be formed. These features, however, bear no particular relation to the present invention but are fully disclosed in my applications Serial No. 56,165, filed April 16, 1901, and Serial No. 56,480, filed April 18, 1901. The type-protecting walls e are located at different distances from the supplemental or space-forming die 6 since the width of the respective type fields vary with the particular types which the dies are adapted to make.

For the purpose of best resisting the forces incident to the forming of wrought types by an operation which involves a working movement for filling the cavity of the working die that creates forces and stresses extending transversely to the line of length of the slide upon which the die is carried as Well as a pressure in the line of depth of the slide the thrust receiving faces are preferably each inclined toward each other and toward the axis of depth of the bar (see the faces 2, 2). These faces are located well toward the outer portion of the channel C, and are adapted to be contacted by correspondingly inclined faces 2, 2, on opposite sides of the corre sponding die slide. Preferably the inclination of these faces to the aforesaid axis will be equal in order to effect symmetry of action and reaction. The faces likewise are disposed in parallelism to each other and extend from end to end of the channel or groove in the carrier and of the bar. Vfith respect to the angle as seen in the cross section of Fig. 1 made by each face to the aforesaid axis it is not designed that the same shall be an angle so acute as to result in a wedging of the slide under forcible compression in the channel in which itis located, but that the angle shall be sufficiently obtuse to cause the elastic return of the metal of the sides of the channel to release the slide after a die has worked to permit the slide to be readily shifted longitudinally. Y

I-nti-mately concerned with the proper working of a die is the resistance to sidewise motion offered by that portion of the supporting slide located at the bottom of the channel. In order that an ample leverage shall subsist adequate to effectually resist all side strains that'may come upon the slide and which tend to tilt the same wnile the die is working, the-shank orstem portion 61 of the slide is extended well toward the center of the carrier, the channel C being made of sufficient depth to accommodate the same. Itis this rear or shank portion of the slide that operates not only to steady the working die but also to effectually guide the slide upon its adjustment, since it is designed that the slide shall spring outward slightly from its channel upon the release of the die from the blank, thus freeing the faces 2, 2 from the thrust faces 2, 2, and permitting the slide to be readily shifted longitudinally of its channel. I find that the best results are attainedby making the sides 3, 3 of the rear or shank portion of each slide substantially parallel-sided and fittingthem between similarly disposed side walls 3 3 of the channel sufficiently tight to prevent side movement, although not so snugly as to prevent the free lengthwise adjustment of the slide.

The proportion and relation of the various faces and parts are such that, ordinarily, during the working of a die toform a type, the reaction surfaces are constituted, asaforesaid, by the- inclined faces 2, 2, the bottom of the slide not contacting under such circumstances with the bottom of the channel.

.VVhen, hon ever, a maximum pressure is exerted against the die, as in forming those types requiring relatively great amounts of working to shape them, the bottom surface of the channel operates as a stop face to prevent undue inward movement of the slide, the faces 2, 2, by reason of the springing of the metal, opening sufficiently to permit the that the latter is cut away to receive the projecting rib l at such apoint as to weaken the main carrier between contiguous slides to the least extent under the application of forces acting substantially transversely to the slides, that is, tangentially of the carrier. Since the rib 4 on each slide acts merely as a stop for preventing the displacement of the slide from position in the holding channel and does not aid in the type-forming operation nor is it instrumental in resisting the stresses incident thereto, ample freedom of. movement is'provided between the faces of the rib and those faces on the carrier in juxtaposition to them. For facility of manufacture I prefer to remove some of the metal lengthwise of the slide thus reducing the bearing surface thereof (see for instance the recessed portion 5 of the slide body).

In manufacturing a die carrier provided with die slides organized and constructed as hereinbefcre set forth, the same will ordinarily be subjected to proper machining operations designed particularly toproduce commercially accurate and satisfactory working faces and such as will render the slidesinterchangeable one with the other.

Although the mode and the mechanism for adjusting a carrier or a slide thereon to position is in nowise related to the application of the invention disclosed herein, the slide, in the form thereof illustrated, is provided with a projecting tooth F adjacent to its rear end with which there isv adapted to engage a slide adjuster F, similar to the adjuster disclosed my application hereinbefore referred to.
