To aZZ whom t may concer/n .f y

Be it known thatl, MARTIN P. CoNNoLLY, a citizen of the United States, residing at Parkersburg, in the county of Wood and State of West Virginia., have invented new and useful Improvements in Typewriter- Oabinets, of which the following is a speciL cation.

This invention relates to that class of typewriter cabinets having a swinging top and typewriter-supporting platform which are so connected that when the top is swung back the platform rises out of the cabinet to place the typewriter in position for use, whereas when the top is swung into position to serve as a desk top, the platform swings back into the cabinet beneath said top.

rlhe invention has for its object to provide a novel and improved operating connection between the top and the platform, which is strong and durable, and which can be readily assembled, and also to provide a construction which enables the platform to be readily removed from the cabinet without disturbing the construction.

With the object stated in view, the invention consists in a combination and arrange ment of parts to be hereinafter described and claimed, and while the preferred embodiment of the invention has been disclosed, it will be understood that various changes and modifications may be made without departure from the spirit and scope of the invention as claimed hereinafter.

In order that the invention may be better understood, reference is had to the accompanying drawings forming a partof this specification, and in said drawings,

Figures 1 and 2 are sectional views of the cabinet with the parts in different positions;

Fig. 3 is a section on the line 3-3 of Fig. 2;

, Fig. 4: is a detail in perspective;

Fig. 5 is an elevation of a sectional bearing member;

Fig. 6 is an elevation of one of the sections of said member and,

Fig. 7 is a vertical section on the line 7--7 of Fig. 5.

Referring specifically to the drawings,the cabinet has a stationary top 9, a bottom 10, a rear wall 11 and side walls 12. The stationary top has an opening to accommodate a swinging top 13, which latter, when it is 1n raised position, is flush with the former so as to be a continuation thereof and to serve as the top of a writing desk.

The swinging platform which supports the typewriter is shown at 14. On top of thisy platform is mounted a slide 15 for holding the typewriter, and to the bottom of the platform, at the side edges thereof are secured angular metal bars 16 mounted to seat over the corners thereof. One of the flanges of each angle bar has an outstanding pivot pin o r trunnion 17, the pivot pins of the respective angle bars being in alinement and projecting outward with respect to the side edges to seat in bearings on the side walls 13 of the cabinet.

Thebearing's for the trunnions 17 are each composed of` two separable top and. bottom sections 18 and 19, respectively. The section 19 is on an attaching or base plate 20, and the section 18 is on a plate 21. The plate 2O is secured to the wall 12 by screws or other suitable fasteners, and the plate 21 is detachably and slidably connected to the plate 20. The plate 21 has a vertical slot 22, and a screw 23 is passed through this slot and threaded into the plate 20, there being a boss 24 on the back of the latter to obtain enough material for a screw hole. By means of the screw 23 the plate 21 is securely clamped to the plate 2O to hold the two bearing sections 18 and 19 in assembled relation. Upon taking the screw out, the plate 21 can be slid upwardly to remove the upper half 18 of the bearing from the trunnion which leaves the platform 141 free to be removed from the cabinet. On the plate 20 is a guide rib 25 for the plate 21.

The connection between the top 13 and the platform 14 comprises the following parts:

On the under side of the top 13 is secured a plate 26 having a depending flange 27 provided with a curved slot 28 running in a direction from the front to the rear of the cabinet. On the wall 12 is also` ful crumed, intermediate its ends as shown at 29, a lever 30 having one of its ends conrolling contact with the angle bar or strip 16. lt will be understood that two levers and associated parts will be provided, one for each end of the platform 14. On the side wall 12 is a roller 34- which seats in the slot 28.

Then the top 13 is up and in position to serve as a desk top, as shown in Fig. 1, the roller 3a is at the rear end of the slot 28, and the roller 33 is beneath the platform ll about midway between its front and rear edges. The lever extends obliquely with respect to the platform 14:, the connection 31 with the top 13, through the flange 27 of the plate 2G being near the rear end of the top. T he pivot of the platform 14C is at its forward end. If now the top 13 is pressed downwardly it swings into the cabi net and assumes a vertical or upright position therein, and at the same time, the lever 30, through the roller 33, elevates the platform li to a horizontal position, as shown in Fig. 2. As the top 13 swings downwardly it is guided by the roller 34 in the slot 28. rl`he downward swing of the top 13 causes the lever 30 to turn on its fulcruni 29 and its end carrying the roller 33 swings upwardly. The roller 33 is loose in the curved slot 32 and slides downwardly7 therein arriving at the lower end of the slot when the lever reaches the limit of its swing and the platform 14 is in horizontal position. The parts therefore work easily and do not bind.

The forward end of the top 13 has the usual depending front wall 35 seating on a cross rail 35 when the top is up, and between this cross rail and the bottom 10 of the cabinet ext-ends a front wall 37 to eX- elude dust and dirt from the interior of the cabinet.

The platform 1411215 upstanding side walls 38 and a rear end wall 39.

On the side walls 12 of the cabinet are stops .l0 on which the top 13 rests when it is up in horizontal position, and on the bottom l0 is a block or rest 41 for the top 13 when it is swung into the cabinet as shown in Fig. 2.

I claim:

1. In a typewriter cabinet, a swinging top, a pivotally supported typewriter platform, and a lever fulcrumed intermediate its ends to the wall of the cabinet, said lever having a connection at one end with the top, and a slidable connection at its opposite end with the under side of the platform, said slidable connection being a roller carried by the lever, and said lever having a slot in which the roller is free to slide.

2. In a typewriter cabinet, a swinging top, a pivotally supported typewriter platform, a slotted plate secured to the top, a lever fulorumed intermediate its ends to the wall of the cabinet, said lever having a connection at one end with the slotted plate, and a slidable connection at its opposite end with the under side of the platform, and guiding means on the top and the wall of the cabinet, said guiding means being a roller on the wall of the cabinet seating in the slot of the plate.

In testimony whereof I aliix my signature.

MARTIN P. CONNOLLY.
