7 Claims.
MY invention relates to a desk adapted to accommodate a typewriting machine and particularly tothe kind of desk known as a pedestal desk. Specifically, the present invention consists in certain improvements in the construction and Cil mode of operation in the form of desk shown .improved engaging means'between the door and table.
Still another object of my invention is to provideV means for preventing the table from swinging out of its vertical position when it is being moved into and out of the pedestal.
My invention also relates to various novel features and details of construction set forth in the following specification and pointed out in the claims.
In the accompanying drawings which illustrate one form oi typewriter desk madev in, accordancewith my invention Figure. 1 is a perspective View., the right-hand; pedestal alone being shown; FigureV 2 is a section taken on the line 2 2. of
YFigure 7; the table being shown in vertical posit-ion.; Figure 3 is a section taken on the line 3T3` of. Figure 8; Figure 4 is a section taken on .the line 4-f4 of FigureS; VFigure 5, isa topplan Avievv,;the desk topbeing removed; Figure 6 isan enlarged section. taken on the line 6 6. oi Figure 7; Figure 7 is asection taken on the line 1 1 'of Figure 8.; Figure 8 is a fragmentary top plan view showing the table in horizontal position; and Figure 9.is a section taken on the line Q-i of Figure 8.
The desk as shown in. Figure 1 is arranged to receive the typewriting machine in the right- It will be understood that this pedestal is connected to a second pedestal containing drawers or other receptacles for maten rial. The pedestal comprises outer and. inner side walls l0 and Il, respectively, a rear wall l2 anda top |73. The front of the pedestal is closed by;Y a, door Hi;` pivotally mounted .by hinges iiito the outer front corner post I6. The hinges are so.constructed` that when the door isl in itsv open position, as shown in` Figure 8, its inner face will lie Substantially flush with; theinner face of post, IB. Secured to,the out erlfront post I6 and the. outer-.rear post .lzl isa. rail.- or. plate. i8. formother support for the carriage is provided by a rail I9 extending between the innerfront corner post I E' and the inner rear corner post I1. This rail is not secured to the posts butv is` carried. on a reenforcing member H of the wall il, being spaced therefrom by. studs 2U. The front end of this rail. is provided with Ya turned over end. 2l cooperating with carriage locking mechanism 22 which is like that shown in my patent above referred to and need not be described in detail.
The carriage comprises an approximately rectangular frame 23 provided at its endy adjacent rail i8 with a downwardly extending end plate 2d. Carried by this plate is a. flanged roller 25 engaging with the upper edge of rail i8 and. a
second hanged roller 26 engaging with the lower* edge of said rail. One side of the carriage is pro.- vided with an. extension 21 projecting over the rail i8 andthe plate 24.. is provided with a pin 28 extending under said rail. The object of Vthese parts 2'! and 28 is to prevent tipping of the carriage on the rollers 25v and 2E. The opposite end of the carriage is provided with a flanged roller 29 engaging with the upper edge of the rail i9, the lower edge being engagedby a pin- 3Q extending under said rail. f
Secured to plate 2.4 isa U-shaped member 3! which forms the support for the inner ends, of two. aligning pivot pins or trunnions 372 from which the table 33y is supported. Surrounding these pins are straps` 34. either formedl integral with or secured toa plate 35 bolted: tothe -rear end 33 of the table 33, which end is reduced in width relative to the main part of the .'table.
Extending longitudinally of the carriage. above the trunnions 32 is a threaded rod 3&5.y Sliding on this rod is a collar 31, the position of which on the rod may be adjusted by a pair ofV nut-s 38 and 39. To the collar is4 attached one end of; a counter-balance spring 4.0, the other end of which is attached to the plate 35.
To provide means for preventing movement of the table into the pedestal when moved out of its vertical position, whichmeans does not depend upon manipulation of locking devices but is positivelycontrolled by the position of the table itself, I provide the lock shown in detail in Figures 2 and v3. A sliding bolt 4l is mounted'on the carriage 23l and adapted to. engageY with a' slot d2 in the rail I8. This bolt is oonnected'to a-levei' 43 by a pin M passing through a slot 43" inthe lever. The lever 43; is pivoted at 14.v toV 'the car.- riage and having a linger i5v adapted; to been.- gaged by a corner ofthe plate 35., a portion; 46
mgm@ 0j me uppolftg for the carriage, The 55. of the table end 33 beingfcut away for. thisfpurpose. A spring 41 attached at one end to the lever 43 and at the other to the frame 23 serves to throw the bolt when not retracted by contact of plate 35 with iinger 45.
When table 33 is in its vertical position, it rests against a ller block 48 secured to the wall IU. To retain the table in this position as it is moved into or out of the pedestal, it is provided with a hook 49 (Figure 3) which, when the table is lowered into vertical position, passes through an opening 50 (Figure') in the plate 24 and passes through a slot 5| in the rail I8 so as to engage with the outer face thereof as the table moves into or out of the pedestal. The table also has secured to its under face a track 52 which engages with a flangedwheel`53 and a pin 54 carried by a bracket 55 secured to post I6. This construction not only provides additional support for the carriage but prevents wobbling of the carriage and its attached table as they are moved into and out of the pedestal.
In my prior application above referred to, I have shown means, brought into operation by the movement of the table into horizontal position, for supporting the outer end of the table from the door and also for camming a stop on the carriage against a stop on its supporting rail to impart rigidity to the structure when the table is in operative position. In the present construction I have provided a device, shown in detail in Figure 6, which performs the same functions and in addition provides locking means for preventing lateral movement between Vthe edge of the table and the door. The door is provided with a recess 56 adjacent which is secured a wear plate 51 having an inclined face 58 to produce the camming eiiect. In the present structure the projecting end of one side of the frame 23 may form the carriage stop adapted to be drawn against a ystop 9 on th'e rail I8. The recess 5S extends below the edge of the body of the wear plate so that its rear face may be engaged by an overturned lip 6D on a plate 6i secured to the edge of the table. This provides a positive locking engagement to prevent lateral movement between the parts.
of the table and before the locking mechanism 22 is brought into operation. The table is held in horizontal position by the engagement of lock 22 with the turned over end 2| of rail I9. When in this position, the engagement of lip 60 with plate 51 effectively prevents lateral movement between the door and table. The arrangement of rod 36, providing adjustment for the counter-balance spring 48, above the trunnions 32 permits the adjustment to be so made that when the table is in vertical position, the spring connection will be swung past the trunnions 32 as shown in dotted lines in Figure 9. When in this position, the tension of the spring does not tend to raise the table but to throw it against ller block 48. This adjusment is of importance when no machine is attached to the table as The typewriting machine 62, shown in dotted y lines in Figure 5, may be secured to the table by means of bolts or screws passing through holes 63 in the table into the frame of the machine. A handle 64 is provided for use in raising and lowering the table. The table is provided with a buier 65 of leather, rubber or th'e like to Contact with the` lower edge of the carriage.
In the operation of my desk, the parts being in the position shown in Figure 5, the door is i'lrst opened to the position shown in Figure '1. The table is then drawn outwardly by grasping the handle 64. During this movement, the engagement of the hook 49 with the rear face of rail I8 and the engagement of the table with the ller block 48 prevent any movement of the table from vertical position in either direction. Also, the engagement of rail 52 with roller 53 and pin 54 prevents wobbling of the table and `carriage which otherwise might occur. The table is now swung into its horizontal position to engage it with the locking mechanism 22. During the rst part of this movement the corner of the plate 35 recedes from finger 45, permitting spring 41 to move. bolt 4l into engagement with slot 42 to lock the carriage against -inward movement during the upward movement it obviates the possibility of violent upward jerk of the table when it is drawn forward. When a. machine is on the table, the adjustment is made ,to throw the spring connection past the trunnions in the other direction (toward the righthand side in Figure 9). The amount of this adjustment will depend upon the weight of the machine as movement of the spring conn'ection past the axis of the trunnion (in the direction stated) will increase the distance between the attachment of the spring to collar 31 and its attachment to plate 35 when the table is in vertical position, and hence its tension at time of starting to raise the table. The division of the trunnion into two parts, between which the spring connection may swing, facilitates the securement of the desired results as it permits the moving of the spring connection past the trunnion axis without tendency to skew the parts such as would result from arranging the connection at one end of the trunnion.
