FRED W. TOBEY, OF GRAND RAPIDS, MICHIGAN.
TYPE-WRITER DESK 0R CABINET.
Application filed February 18, 1918.
To all whom it may concern:
Be it known that I, FRED W. TOBEY, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Type-Writer Desks or Cabinets, of which the following is a specification.
This invention relates to improvements in typewriter desks or cabinets.
The main objects of this invention are:
First, to provide an improved typewriter desk or cabinet in which the typewriter is at all times maintained in a horizontal posi tion.
Second, to provide an improved typewriter cabinet or desk in which there is the desired knee room when the typewriter is collapsed into the cabinet and also when it is extended for use.
Third, to provide an improved typewriter desk or cabinet having a relatively small cut out or opening in the top of the desk or cabinet, thus providing a maximum free space on the desk top.
Fourth, to provide an improved typewriter desk or cabinet which is simple and easy to operate to extend and erect the typewriter and to collapse or retract it into the cabinet.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:
Figure I is a front perspective view of a structure embodying the features of my invention with the cabinet open and the typewriter bed erected, a typewriter not being shown.
Fig. II is a detail vertical transverse section on a line corresponding to line 2-2 of Fig. V'with the bed collapsed and the cover closed.
Fig. III is a similar detail vertical section with the cover partially open and the bed partially erected.
Fig. IV is a similar detail vertical sec-v Specification of Letters Patent.

Serial No. 217,807.
tion on a line corresponding to line H of Figs. I and VI, with the cover fully open and the bed erected.
Fig. V is an inverted detail with the parts collapsed.
Fig. VI is an inverted detail with the parts erected.
Fig. VII is a detail view partially in section on a line corresponding to line 7-7 of of Fig. V.
Fig. VIII is a detail section on a line corresponding to line 88 of Fig. VI.
Fig. IX is a detail vertical section on a line corresponding to line 99 of Fig. II, showing details of the carriage and its mounting.
Fig. X is a detail perspective view of a modified embodiment of my invention.
Fig. XI is a detail view partially in section on a line corresponding to line 11-1l of Fig. X.
Fig. XII is a detail view similar to that of Fig. XI showing the bed in its collapsed position.
Fig. XIII is an enlarged detail section through the actuating lever on a line corresponding to line 1313 of Fig. XI.
Fig. XIV is a detail section on a line corresponding to line 1414 of Fig. XI, showing details of the locking means.
Fig. XV is adetail vertical section on a line corresponding to line 15-15 of Fig. XI.
In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
' Referring to the drawing, the cabinet 1 is of the desk type. The cabinet is provided with a space 2 open at the front and having a cut out or opening 3 in the top 4. This cut out or opening is provided with a cover or lid 5 formed, in the structure illustrated, of sections hinged together, the rear section being hinged to the top at 6.
The object of forming the top in sections is to allow them to fold together as shown in Fig. I to make them more compact when the cover is open. When closed the cover lies flush with the top of the desk and constitutes a part thereof.
A carriage comprising, in the structure illustrated, a pair of end members 7 connected by a cross bar 8 are mounted to re-.
ciprocate within the cabinet, the end members being provided with rollers 9 traveling in ways 10 secured in an opposed relation on the walls of the cabinet. The bar 8 is arranged toward the rear of the end members so as not to obstruct the knee space.
On the inner side of each end member I mount supporting bars 11, the bars "being secured by screws 12. On each supporting bar I mount a pair of bell crank levers 13, the pivots 14 being disposed at the angles of the levers.
The bed 15 is mounted on corresponding arms of the levers 13, the bed being provided with hangers or brackets 16 secured to the levers by the pivots 17see Fig. III. The other arms of the levers 13 are connected by the yoke-like links 18, the links being secured to the levers by pivots 19. Actuating levers 20 are secured to the carriage end members by plates 21 which carry pivots 22 for the levers. These levers are connected to the links 18 at a central point by means of pivots 23.
On the swinging ends of the levers I mount a fall board 24 adapted to swing down in front of the bed when the same is collapsed,-see Fig. II, and to the rear thereof when the same is erected,see Fig. IV. This fall board is connected to the levers by means of the brackets 25 engaging pivots 26.
Stops 27 are provided on the brackets to limit the tilting movement of the fall board. The tilting of the fall board permits it to clear the cover when opened so that the opening or cut out in the top of the desk may be kept relatively small.
To automatically retract and extend the carriage when the cover is opened and closed I provide the cover with a lever 28 which projects downwardly on the outer side of one of the carriage end members 7 and is connected thereto by means ofthe link 29. The operating connections for the levers 13 provide a locking means therefor.
By thus connecting the cover and carriage the carriage is retracted, as shown in Fig.
VII, when the cover is closed and extended, as shown in Fig. IV, when the cover is opener The cover not only serves as means for actuating the carriage but as a retaining means therefor.
By mounting the bed as I have described sufiicient movement thereof is secured so that it is swung into and supported in erected position for use or dropped to collapsed position in which position it may be moved into the cabinet.
In the modification shown in Figs. X'XV inclusive I have embodied my improvements in a pedestal type of desk, the pedestal 30 being provided with a cabinet space 31 in which the carriage 32 reciprocates. In this embodiment the carriage body 3% is pivoted on the carriage slide 32 at 35 so that it may be swung to convenient position for the operator. The outer end member 33 of the carriage body constitutes a closure member for the cabinet.
The bed 36 is carried by pairs of bell crank levers 13 pivoted at 1% on the supporting bars 14. The bed 36 is mounted upon corresponding arms of the levers 13, the other arms of which are connected by the yokelike link 18 as in the other embodiment described.
The actuating lever 37 is pivoted at 38 and with a link 18 at 39. This actuating lever is provided with a collapsible section 40 providing a handle 41.
To retain the parts in their erected position I provide a pin 42 positioned so that when the collapsible section -10 is drawn out as indicated by dotted lines in Fig. XI it clears the pin, but when shoved in into the position indicated by full lines it engages the pin.
I have illustrated and described my improvements in two forms in which I have embodied the same in practice. I have not attempted to illustrate or describe other modifications in the form of desk or cabinet or other adaptations of the mechanism, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
