PAPER-RACK.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed May 22, 1913. Serial No. 769,254.

To all whom it may concern:

Be it known that I, BYRON T. MILLS, acitizen of the United States, residing at Las Vegas, in the county of San Miguel and. State of New Mexico, have invented certain new and useful Improvements in Paper Racks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements. in paper racks and particularly to racks for use in connection with typewrit-ingmachines. for holding carbon paper, finished work and the like in convenient position to be reached by the operator.

Another object is to provide a rack of this character having improved means for attaching the same to the base board of a typewriter whereby the racks may be swung upwardly to permit the cover of the typewriter to be placed in position over the same or which will permit the racks to be disengaged from the base member to permit the cover to be placed thereon.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of a typewriter base board showing my improved racks applied thereto and in position for use and illustrating in dotted lines the manner in which said frames may be swung upwardly to permit the cover of the typewriter to be placed thereon; Fig. 2 is a detail vertical section of I a portion of the base board and a side View of a portion of one end of one of the racks showing the manner in which the latter is connected to the base board to be swung to operative and inoperative positions; Fig. 3 is a vertical sectional view showing a side view of one lower corner and attaching member of the rackyFig. 4 is a detail perspective view of a portion of the base board showing the manner in which the same is notched and recessed to receive the attaching members of the rack; Fig. 5 is a similar view of one of the clips for holding the base engaging portions of the rack in pivotal connection with the base board; Fig. 6 is a detail perspective view of a slightly modified construction of the pivotal connecting or attaching members of the rack; Fig. 7 is a view similar to Fig. 2 illustrating in full and dotted lines a modified arrangement of the rack attaching mechanism whereby the racks are pivotally and detachably secured to the base member; Fig. 8 is a detail perspective view of a portion of the base member showing the manner in which the same is constructed to receive the rack attaching member shown in Fig. 7 Fig. 9 is a detail perspective view of a portion of one end of the rack frame and the attach.- ing member shown in Fig. 7; Fig. 10 is a similar view of, a modified form of the rack attaching member shown in Fig. 9. Fig. 11 is a similar view showing another modified construction and arrangement of the parts shown in Fig. 9.

In the present embodiment of the invention wherein my improved racks are shown as applied to the base board or member B of a typewriting machine, 1 denotes the racks which are in the form of wire frames the upper and lower side bars of which are bent to form series of inwardly projecting rectangular loops 2 which form a filling for the frames and prevent the paper supported by the racks from falling therethrough. The end bars of the rack frames are extended downwardly below the lower cross bars thereof as at 3 and in the first form of the invention are bent upwardly upon themselves to form combined stop and detent engaging lugs 4. The ends after being bent upwardly to form the lugs 4 are bent laterally at right angles to the ends of the frames and parallel to the lower cross bars thereof to form pintles 5 as clearly shown in Fig. 3 of the drawings.

.It will be obvious that instead of bending the extended endsof the end bars upwardly and inwardly on the inner side of the extensions in forming the lugs 4 and pintles 5 that said extended ends may be bent upwardly on the outer side of the extension in forming the lugs and bent outwardly at right angles and in exactly the reverse directions from that shown in Fig. 3 to form the pintles5. It will also be obvious that in addition to forming the lugs t and pintles 5 as shown in Fig. 3 of the drawings, I may secure to the outer side of the extensions 3 of the end bars a short rod 6 having a right angular inner end which is soldered or otherwise rigidly secured to the outer side of the extension 3 as clearly shown in Fig.

6 of the drawing, said rod 6 forming an additional pintle projecting in the reverse direction from the pintle 5 and providing an increased bearing for the attaching mechanism of the racks.

The extended ends of the racks and the attaching mechanism when constructed as herein shown and described are adapted to be engaged with vertical notches 7 formed in the side edges of the base member near the ends thereof as shown. The notches 7 communicate at their lower ends with inwardly extending recesses 8 formed in the lower side of the board B, said recesses having inclined upper walls 9' as is clearly indicated in Figs. 2 and 4 of the drawings.

In the side edges of the base member adjacent to one or both sides of the notches 7 are formed longitudinally disposed bearing grooves or recesses 10 one of the ends of which communicate with the notches 7 as clearly shown in Figs. 3 and 4; of the drawings. It will be understood that the bearing grooves or recesses 10 are arranged to correspond with the construction or arrangement of the pintles 5 and 6 and that when the attaching members of the racks are provided with both of the pi-ntles 5 and 6 which project in opposite directions, the grooves or recesses 10 will be formed on both sides of the notches 7 in the edges of the board.

The notches 7 and recesses 8 when formed in the manner described are adapted to receive the extended ends 3 and lugs 4 of the rack attaching mechanism, while the bearing grooves 10 are adapted to receive the pintle's of said attaching mechanism, said pintles being pivotally engaged with the grooves whereby the racks may be swung outwardly at a suitable angle to form supports for the papers engaged therewith and may be swung upwardly to -vertical positions as clearly indicated in full and dotted lines in Figs. 1 and 2 of the drawings. When the racks are swung upwardly to vertical positions as shown in dotted lines, a typewriter case may be readily placed over the racks and engaged with the edges of the base board or member so that the latter may be employed in the usual manner for forming the bottom of the case or cover. When the racks are swung outwardly to operative positions the outward movement thereof is limited by the engagement of the lugs 1 with the inclined upper walls 9 of the recesses 8 as clearly shown in Fig. 2 of the drawing.

The extended ends of the rack frames are held in operative engagement with the notches 7 and the pintles 5 are held in pivotal engagement with the grooves 10 by sheet metal clips 11 which are enga ged with the edges of the base board over the notches and grooves therein as shown. The clips 11 are secured to the board by screws or other fastening devices and in the upper and outer sides of the clips are formed notches 12 through which the ends 3 of the rack 7 frames pass and which permit said frames to be swung to operative and inoperative positions in the manner described. In the lower sides of the clips 11 and below the recesses 8 are upwardly projecting detents 13 which are preferably formed by striking up or indenting the metal forming the lower sides of the clips. The detents when thus constructed and arranged are disposed in the path of movement of the lugs 1 on the extended ends 19 of the rack frames so that when said frames are swung upwardly and inwardly to inoperative position the lugs 4 will spring over the detents 13 which will hold the racks in their vertical or inoperative positions.

When the racks are employed in connection with low typewriters or where the racks are of greater width than the height of the casing or cover of the typewriter it is necessary to remove the racks before applying the case, and in order to permit this removal of the racks a slightly different attaching mechanism is provided which necessitates a slightly different construction and arrangement of the frame receiving notches and bearing grooves in the base member or board. This modified arrangement of the notches and bearing grooves in the base member and the modified construction of the attaching mechanism for the racks is clearly shown in the last five figures of the drawings. By reference to these figures it will be seen that the ends of the racks are provided with extensions 14 corresponding to the extensions 3 shown in the first form of the invention and which have secured to their lower ends a combined stop lug 15 and pintle 16. The pintle 16 extends at right angles to the extension 14 and may project inwardly therefrom as shown in Fig. 9 of the drawing or may project outwardly in the opposite direction as will be readily understood. It will also be obvious that the attaching member of this form of the invention may be constructed as shown in Fig. 10 of the drawings to provide a pintle 17 projecting from both sides of the extension 14, which, in this instance, is bent around the pintle midway between the ends thereof and is then extended downwardly to form a stop lug 18 which corresponds to the stop lug 15 of the form shown in F ig. 9. In either of these forms of the attaching mechanism the pintle member is soldered, welded or secured to the extension 14 in any suitable manner.

In Fig. 11 is shown a modification of the form and arrangement of the extension, pintle and stop lug shown in Figs. 7 and 9. In the construction of these parts as shown in Fig. 11 the extension 1% is bent upon itself to form a stop lug 15' and is then bent laterally at right angles to form a pintle 16. By this arrangement it will be seen that the extension, lug and pintle are all formed in tegral with the ends of the racks, similar to the arrangement shown in Fig. 3 of the drawings. The base board or member for this form of the invention has formed therein at suitable points, vertical notches 19 the lower ends of which terminate in an inwardly extending recess 20 having an inclined upper wall 21 somewhat similar to the notch and recess shown in the first form of the invention except that the recess 20 is of greater height than the recess 8 and the inclined upper wall thereof extends to the upper end of the notch 19 as shown. In the upper side of the board or base member adjacent to and extending from one or both sides of the notch 19 is a bearing groove 22 the inner end of which communicates with the notch 19 as clearly shown in Fig. 8 of the drawings. The bearing groove 22 corresponds to the bearing groove 10 in the first form of the invention and is provided to receive the pintles 16 and 17 of the attaching mechanism shown in Fig. 9 or that shown in Fig. 10. It will be understood of course that for the attaching member shown in Fig. 10 the groove 22 will necessarily be formed on both sides of the notch 19.

When the last described form of the rack is applied to the baseboard the extended ends 14 of the racks are engaged with the notch 19 while the stop fingers 15 or 18 at the lower ends of said extensions will engage the recesses 20. When thus arranged the pintles of the attaching mechanism will pivotally engage the recess 22 thus permitting the racks to be swung outwardly to an operative position. lVhen the racks are thus swung outwardly the stop lugs 15 or 18 as the case may be are brought into engagement with the inclined upper walls 21 of the recesses 20 thus limiting the outward movement of the racks and supporting the latter in operative positions. When it is desired to remove the racks it is simply necessary to swing the latter upwardly to a vertical position as shown in dotted lines in Fig. 7 of the drawing, whereupon the racks may be lifted and the pintles and stop lugs thereon disengaged from the grooves 22 and notches 19 thereby entirely separating the racks from the base member.

In the last form of the device the outer ends of the notches 19 are covered by metal clips 23 which are constructed somewhat similar to the clips 11 shown in the first form of the device except that the upper sides of the clips 23 are cut away or recessed for a suitable distance beyond the notches 19 as shown at 24 and have in their outer sides and in line with the notches 19 short notches 25 which permit the extensions 14L on the ends of the racks to swing outwardly when the latter are arranged in operative positions. The upper sides of the clips when cut away in the manner described permit the pintles on the extensions 14 to be readily disengaged from the grooves 22 when the racks are removed.

, From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be more readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

1. The combination with a base member having notches in one side edge, of a rack frame having its ends extended to form notch engaging members adapted to be inserted into the notches of said base member, pintles on said notch engaging members having a pivotal engagement wlth said base member, stop lugs on said notch engaging members, clips secured to the edges of the base member over the notches therein, and detents formed in said clips and adapted to be engaged by said stop lugs when the rack frame is swung inwardly and upwardly to operative position.

2. The combination with a base member having in its side edges vertically disposed notches communicating at their inner ends with recesses having inclined upper walls and bearing grooves communicating with said notches, of rack frames having their ends extended to form notch engaging members adapted to be inserted into the notches of said base member, pintles on said notch engaging members and having a pivotal engagement with the bearing grooves in said base member, stop lugs formed on said notch engaging members and adapted to be swung into engagement with the inclined upper walls of said recesses, clips secured to the edges of the base member over the notches therein and detents formed in said clips and adapted to be engaged by said stop lugs when the rack frames are swung inwardly and upwardly to operative positions.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
