William Wockenfuss, Union, N. J., assignor, by
mesne assignments, to Burroughs Adding Machine Company, a corporation of Michigan Application October 16, 1948, Serial No. 54,933 7 Claims. (Cl. 101,-109) This invention relates to improvements in printing devices and has particular reference to a type bar contruction such as used on record controlled tabulatingl machines and the like.
An object of the invention is to facilitate the mounting and replacement of type elements in a container by providing the body of the latter with a removable cover member and forming on said container and member coacting means which interengage to securely retain the cover member in operative position and which also permit of said cover member being readily removed to gain access to said type elements.
Another object is to provide an improved printing device wherein a type container which is removably mounted upon a type bar is securely held thereon, against accidental displacement, by a locking element whichcoacts with portions of said container and bar to releasably connect the same together in such manner as to enable the container to .be readily removed from the bar when repairs to or replacement of said container and the type elements therein are necessary.
Another object is to provide the typecontainer with means which cooperate with a removable cover to secure the latter in retaining position relative to a locking element that joins the container to a type bar. u f
The inventive idea involved is capable of receiving av variety' of mechanical expressions, one of which, for purposes of illustration, is shown in the accompanying drawing;` but it will be expressly understood that said drawing is merely used for the purpose of'illustrating the invention as a whole and not to dene the limits thereof, reference being had to the appended claims for this purpose.
,Inthe drawing: .Y -v
Fig. 1 is a fragmentary side' elevation, partly broken away, of a printing device constructed in accordance with the invention;
. Fig. 2 is a section taken on the line 2-2 of Fig. 1;
Fig. 3: is a transverse section on the line 3-3 of Fig. 1;
Fig. 4 is a fragmentary perspective view of the body of the container in which the type elements are mounted; 1
Fig. 5 is a similar view of the removable cover member for said body;v c
Y Fig. 6 is a perspective view of a locking element employed to releasably connect the type container to a type bar; and
. Fig. 7 is a fragmentary perspective view of the type bar. v
In accordance with one of the features of the present invention.l the upper end of the type bar 8 is provided with a bifurcation 9 enlarged transversely at its inner end to form locking sohulders I. and further enlarged at its outer end to provide stop shoulders I I, the purposes of which will appear in the course of the description.
The body of the type container, generally indicated at I2, which is removablymounted upon the type bar 8 is stamped or otherwise formed from a single sheet of materialto provide the back I3' having side walls I4 extending along the longitudinal edges thereof. At the lower end of the body and at an intermediate portion thereof the side walls have extending inwardly therefrom two pairs of nanges I5 and I6 spaced apart and constituting permanent and partial closure for said body, and in the space between said pairs of fianges and spaced therefrom is a pair of opposed inturned lugs I1 forming retaining elements, the purpose of which will later appear. At a point adjacent the lower end of the back I3 of the container body a guide I8 is struck therefrom which engages in the bifurcation ofthe type bar as the container is being mountedl thereon to guide the latter into proper position on the bar. At an intermediate point of the back I2 directly beneath the anges I6, said back also has struck therefrom a substantially circular projection or boss I9 which, when the container is properly disposed upon the type bar, will be contacted by the stop shoulders II of said bar to limit the movement of the container to its proper position. Said boss I9 is provided therein with an opening 2U in alignment with the bifurcation 9 in the type bar for a purpose which will appear in the course of the description. The upper portion of the container body I2 is open faced and the parts of the side walls I4 extending along said portion are provided with pairs of re-entrant slots 2i in which the type elements 22 of well known construction are adapted to be removably mounted, each of said elements being provided with a recoil spring 23 for restoring the element to its normal position shown in Fig. 1 after it has been operated to .print a character in a manner well known in the tabulating art.
The invention further provides a device for releasably interconnecting the type container with the type barin a manner which will prevent accidental detachment of said container during operation of the tabulating machine, and particularly when the type bars are arrested in their printing position which operation is usually accomplished by engagement of a pawl with a tooth through the opening 20 therein with the upper f portion of the element 24 disposed within the upper end of the bifurcation 9 when the container is mounted on the type bar, andv the' remaining portion of said element 24 being in alignment with said bifurcation and slightlybowedso. as
container body, as best illustrated in Fig. 2. Due f* to this biased said condition of said element 24, it will be apparent -that when vthe containeris monnted upon theV typelbarwith the-boss I9 in engagement with the shoulders I I `off said bar, the inner edges of the offset locking head 26 rwill engage the shoulders I at the'inner-end of the bifurcation 9 in the type bariand will thus securely lock the container thereon. A lip 28- at the free extremity ofthe head 26 is providedfin order that the element 24 may be exed outwardly against its normal tendency to remain in locking position, to dis-engage the locking head from theshoulders preliminary to' detaching the container from the typebar.l 'Y
Afterthe locking `element 24 has beenso -positioned the cover plate 27 is mounted in place to retain said element 24 in such positionl and to close the upper open faced portion of the container body in which the type elements 22 are disposed. In mounting the cover member on the body, the flanged andI oifset llower portion 29 thereof isrstinserted overthe cover sections I6 and then under the inturned lugs I1, Aas indicated in dotted lines in Fig.- 4. This will dispose the cover memberat a slight angle to-the body of the container with the closurefiange 3Q at the upper end of said vcover extending slightly beyond the upper end of the body I2.' inward pressure is then exerted upon the upper endlcf Vthe cover to iiex the sametoaposition whereinthe intermediate portion of the covertwill engage-the free edges of the side walls" I4 of .the body, and then downward pressure.` isV applied yto said' cover to force the lower portion 29 completely. 4under the retaining lugs I1A so.' that theiiange 3l at the lower extremity of the Scover -willengage-behind said lugs and thus lock the cover against a reverse or upward movement. The lclosure flange 30 at theupper'end of the cover is provided'at its ends with notches 32 :which receive lugs 33 formed at the upper ends;of the side lwalls. I4' of the body when said; cover is in the lastdescribed position, and the interengagement ofsaid closure 30 with the lugs 33 will retain .the cover member, in its slightly flexed conditiongagainst the side walls I4 so as to fully enclose. the.ty.pe'..elel ments 22. With the cover member in its operative position it will be apparent from Fig. 2V that the lower offset portion 29 tl1ereofwill..engage the shank of the locking element-.24 and prevent it from becoming. displaced from "itsoperative position in alignment with the bifurcation '9 in the type bar, and will also exert sufficient inward pressure upon said element to retainthe locking head 26 in engagement with the shoulders I0 until said locking head is forcibly sprung outwardly preliminary to removing the container from the type bar. The upper edge of the back I3 of the container body is provided with a notch 34 for the insertion of a tool utilized to spring the closure 3U out of engagement with the lugs 33 when it is desired to remove the cover member from the container.
