' Referring to the drawings in detail, A designates generally a portion of an article of furniture having a top l0, and B designates, generally,

said top to dispose a machine or device carried thereby for convenient use, and for downward swinging movementand rearward sliding movement to a substantially vertically disposed, retracted position beneath the top In to dispose the machine or device in a'stored or ouLt-of-theway position beneath said .top.

In 'the'drawings' the portion of the article of furniturev illustrated is the right hand part of adesk having a compartment H to accommoand rearward sliding movements.

date the shelf B and the machine or device (not shown) carried thereby when the shelf is in its retracted position. As will hereinafter become fully apparent, however, the compartment II is not necessary since the shelf, and a machine or device carried thereby, would be disposed equally as well in a stored or out-of-t'he-way position beneath the top I whether the compartment II is or is not provided. Accordingly, while in most instances the shelf B will be associated with a desk having a compartment such as the compartment II, as illustrated in the present instance, it is to be understood that this ismerely by way of example and not limiting as the article of furniture A may equally as well be a cabinet, a table or the like.

According to the specific, practical embodiment of the invention illustrated in the present instance, vertically disposed channel members I2 are suitably fastened against the inner face of the outer side wall I3 of the compartment II and have suitably fastened thereto forwardly and rearwardly extending track members I4 with which are engaged rollers I5 carried by a .car-

riage designated generally as C, whereby said carriage is mounted for free and easy forward In this connection and in order to assist the track members' I4 and the rollers I5 in firmly yet slidably supporting the carriage C, said carriage, which is in the form of an elongated plate, preferably isprovided with a forwardly and rearwardly extending track member I6 which is engaged by a fixedy positioned roller [1. However, said track member I6 and roller I! are not essential and may be eliminated if desired.

The shelf 2 is hinged in the present instance adjacent to its outer or right hand edge to the carriage C adjacent to the top of the latter, as indicated at I8, and therefore is movable forwardly and rearwardly with said carriage. Moreover, due to its hinged connection with the carriage C, said shelf B is swingable upwardly and inwardly to a substantially horizontally disposed position, as shown in Figs. 1, 2 and 3, and downwardly and outwardly to a substantially vertical position as shown in Figs. 4, 5 and 6.

In the front of the compartment II is a doorway I9 through which the shelf B, the carriage C and a typewriter or other machine or device carried by said shelf are movable, while controlling said doorway is a hinged door 20.

Rearward movement of the carriage C is limited by a suitable fixed stop element 2| (Fig. 6),

while forward movement of said carriage is limited by a suitable fixed stop element 22 engageable by a plate 23 carried by said carriage, said plate being pivoted as at 23 so that it may be swung to permit the carriage C to be removed from and to be operatively mounted in the compartment I I andhaving a normal position which it assumes under the influence of gravity so that when it is released following operative mounting of said carriage in said compartment it thereafter acts in cooperation with said stop element 22 to limit forward sliding movement of said carriage.

Suitably fastened to the carriage C at the rear end thereof is a bar 24 the lower end portion of which is in the form of an inwardly extending arm 25, while suitably fastened to the rear end of the shelf B is a plate 26. Pivoted at 21 to the inner end of the arm 25 for swinging movement about a forwardly and rearwardly extending axis is an angle member 21 having a substantially horizontal flange 28, while pivoted at 26 to the plate 26 for swinging movement about a forwardly and rearwardly extending axis is an angle member 29 having a substantially horizontal flange 3U.

Fastened at its lower end to the flange 28 of the angle member 21 is a rod 3| which extends upwardly through an opening in the flange 30 of the angle member 29 and which has threaded thereon near its lower end a thumb nut 32, while surrounding said rod between the flange 30 and said thumb nut 32 is an expansion coil spring 33 which tends constantly to swing the shelf B upwardly and inwardly. The thumb nut 32 constitutes, of course, an adjustable means for regulating the force of the spring 33 so that when said spring is permitted to act it will positively swing the shelf B upwardly to its operative position at a desired rate of speed.

Pivoted to the shelf B for forward and rearward swinging movement is a latch 34 which is constantly urged forwardly by a suitable spring 35 to a position at substantially right angles to said shelf against suitable stop means 36 and which is recessed or otherwise suitably formed at its front edge to provide a lip or hook 31 for engagement with a suitable keeper carried by the carriage C, said keeper. being constituted in the present instance by a portion 38 of the carriage C at the forward end of a slot 39 insaid carriage through which the free end portion of the latch 34 passes when the shelf B is swung downwardly to its substantially vertically disposed position. In this connection it will be observed by reference to Figs. 7-to 9 of the drawings that the front edge of the free end portion of the latch 34 is inclined upwardly and forwardly to the lip 31 and that the edge of the carriage C at the front end of the slot 39 is disposed to be engaged by the said inclined front edge of the latch 34 when the shelf B is swung downwardly to its vertical position. Accordingly, the final portion of downward swinging movement of the shelf B, as indicated by the arrow a in Fig. 7, will result in the latch 34 being swung rearwardly as indicated by the arrow b in said figure until the lip 31 is disposed at theouter side of the plate comprising the carriage C, whereupon the spring 35 will act to swing said latch forwardly to engage the lip 31 with the keeper 38 and thus latch the shelf 34 in its downwardly swung, substantially vertically disposed position against the force of the spring 33 as illustrated in Fig. 8.

When the shelf B is latched in its downwardly swung, substantially vertically disposed position it may be slid, by reason of its carriage support, entirely into the compartment II as shown in Fig. 4 to dispose a typewriter or other machine or device mounted thereon in a stored or out-of-the-way position in said compartment, and the door 20 may then be closed. Likewise, by first opening the door 20, said shelf B may be slid forwardly to dispose the typewriter or other machine or device carried thereby forwardly of th front of the compartment I I so that when the shelf then is swung upwardly to its substantially horizontally disposed position the typewriter or other machine or device will be disposed in a position for use. In this connection it will be noted that the latch 34 is disposed near the rear end of the shelf B and that a fixed latch releasing element 40 is mounted near the front of the compartment II in a position to be engaged by the front edge of the free end portion of said latch in response to forward movement of the shelf B and .just prior to said shelf reaching its limit of forward movement as determined by engagement of the plate 23 with the stop element 22. Accordingly, thefinal portion of forward sliding movement of the shelf B results in the latch 34 being swung rearwardly by the latch releasing element 40 to disengage the lip 31 from th keeper 38 (see Figs. 8 and 9) and when release of said latch thus is automatically effected, the spring 33 then is free to act to swing the shelf upwardly to its'substantially horizontally disposed operative position.

When the shelf Bis at its limit of forward movement the rear end portion thereof is disposed in the front end portion of the compartment II as shown in Fig. 1 and in this connection it will be observed that the said rear end portion of said shelf has projecting from each side edge thereof a pair of pins 4| to enter flaring-mouth recesses 42v in a pair of keeper plat- es 43 and 43, the former of which is fixedly mounted at one side of the compartment II and the latter of which is inverted relative to the former and is fixedly mounted at the opposite side of the compartment I I whereby upward movement of the shelf under theinfluence of the spring 33 is limited and whereby said shelf also is positioned and is held effectively against forward or rearward movement when it is disposed in its upwardly swung substantially horizontal posi- .tion. (Figs. 1, 2 and 3.)

To look th shelf against downward swinging movement from its substantially horizontal position said shelf is provided with a pair of lockingbolts 44 to enter openings 45 in the keeper plates 43 and 43 when said shelf reaches its limit of upward swinging movement as determined by engagement of the pins 4| with the bottoms of the recesses 42. These locking bolts 44 are disposed transversely of the shelf B at the top thereof and at or near their outer ends are slidable in guides iii carried by said shelf and at their inner ends are connected with a lever arm 41 to opposite sides of a pivotal connection 48 of said lever. arm with said shelf. Thus, by swinging movement. of said lever arm in one direction the bolts 44 are projected and by swing ing movement of said lever arm in the opposite direction said bolts are retracted. (Figs. 1, 3 and 4.) The lever arm 41 includes an offset portion 49 extending downwardly. through a slot 50 in the shelf B-and a handle portion 5| extending forwardly beneathsaid shelf from said offset portion sothat it mayreadily be grasped to swing said lever to. retractthe bolts 44' when the shelf is inits horizontal position.

Suitable spring means 52 tends constantly to swing the lever arm 41 in adirection to project the bolts 44 and any suitablemeans may be provided to limitv swinging movement of said lever arm by said spring means. For example, one end of the slot 50 may constitute a stop engageable by the offset portion 49 of said lever arm for this purpose. In any event, the bolts 44 are normally projected, and in this connection it is point-ed out that either or both of the plates 43 may have an inclined or cam portion 53 (Figs. 2 and leading to the related opening 45 to be engaged by the end'of the relatedbolt 44 during the final portion of upward swinging movement of the shelf whereby the bolts are retracted to be projected into the openings 45 when they become alined therewith asthe shelf reaches its limit of upward movement.

Upon" projection of the bolts 44 into the open ings the shelf B becomes effectively locked in its horizontal or operative position, thereby 'securely'supporting the typewriter or other machine or device in a position for use. However, by means of the handle portion 51 of the lever arm 41 said-lever arm may readilybe swung to retract the bolts; and when said bolts are re.- tracted the shelf then is free tobe pressed downwardly-and outwardly to its substantially ver tica'lly disposed position preparatory to being slid rearwardly 'to store the machine or device carried thereby-in the compartment H. i

As the shelf'is swung downwardly it is moved slightly rearwardly so as to avoid interference of the element 40 with engagement of the latch 34 with the keeper 38. Accordingly, when the shelf reaches its downwardly swung vertical position it becomes latched in such position as heretofore explained and all that then is necessary to be done to store the machine or device isto push or slide the shelf into the compartment H. The door 20 may then be closed. On the other hand, to again position the machine for use, the door 20 is opened and theshel'f'simpl'yi is slid forwardly until the latch 34 is released by the. element-4'0, whereupon thespring 33 acts automatically to swingthe shelf upwardlyto its horizontal position, the pins 4| became engaged in the recesses 42,.and the bolts 44' automatically enter the openings 45. g Q

Preferably, but'not necessarily, the shelf B is provided with a roller '54" to engage a trackway 55 when the shelf isswung downwardly to'and latched in its 'vertical position to thereby assist in supporting and guiding the shelf and carriage for rearward and forward sliding movements.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled'in the art, and it will of course be understood that changes in the form, proportion and minor deswinging movement to a projected substantially horizontally disposed operative position atythe front of, said top and for downward swinging movement and rearward slidingvmovementto a substantially vertically disposed retracted ma chine storing position beneath said top, spring means tending constantly to swing said shelf upwardly', releasable latch means to hold'said shelf in itsdownwardly swung position when same is retracted, and means operable in response'to forward sliding movement of said shelf to release said latch means and thus permit said spring means to swing said shelf upwardly to its said operative position.
