ALEXANDER T. BROWN, OF SYRACUSE, NElV YORK.

TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No. 484,136, dated October 11, 1892.

Application filed May 23, 1892. Serial No. 433,980. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER T. BROWN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Type -Writer Cabinets, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. I

My invention relates to type-writer cabinets; and my objectis to provide an improved mechanism for supporting the table and for opening or closing the cabinet, and in which the opening or closing of the cover either swings the table forward and upward or backward and downward, thus either bringing the machine into operative posit-ion or inclosing it within the case under the cover.

My invention consists in the several novel features of construction and operation hereinafter described, and which are specifically set forth in the claim hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1 is a plan perspective of the cabinet, partly open. Fig. 2 is a sectional transverse section of the same, partly open. Fig. 3 is a like section of the same closed. Fig. 4 is a like section of the same open. Fig. 5 is a plan view of the shaft and arms carrying the front of the table.

A is the case, comprising a vertical hack a, vertical sides I), an open front, and a top or cover composed of a stationary section 0 and a movable section 0, adapted to be opened or closed. A swing-bar d is pivotally connected at one end to the cover '0 and at the other end to the side I). One of these bars is provided at each end of the cover. Therear of the cover is connected at each end to the end of a lever e, pivotally mounted upon the side of the case, as at e, which is its fulcrum. The other end of said lever is pivotally connected to the table m or to an ear m thereon. The front of the table is provided with ears n, in which the ends of the shaft of are journaled, said shaft being provided with arms n, which are pivotally connected to the sides I) of the case.

Starting from the position shown in Fi 3, when the cover is raised the lever e is depressed at the end connected thereto and the other end is raised, lifting the table with it, as shown in Fig. 2, and then as the movement of the cover continues said cover gradually becomes more vertical until it finally assumes the vertical position shown in Fig. 4 and the table isin the horizontal position shown therein. During this opening of the cover and the raising of the table it is carried in front by and swings upon said shaft, and when said table is horizontal its front edge is supported by said shaft the arms of which are then in a vertical position. It will be observed that the rock-shaft may be omitted and the arms be pivotally connected to the table and case.

The primary object of my construction is to reduce the projection of the table beyond the front of the cabinet, so that an operator can close the cabinet and write upon its cover or open it and bring the machine into operative position without moving his or her seat forward to conveniently use said cover or back to get out of the way of the table,a1l of which is accomplished by mounting the table upon the swinging arms a" and dispensing with any devices which permit the table to slide to attain or increase its outward projection, and at the same time dispensing with all counterbalance to assist in the disappearance of the cover.

What I claim as my invention, and desire to secure by Letters Patent, is-- A type-writer cabinet comprising a case, a cover, a connecting-bar pivoted to the case and cover, a table, lugs and ears thereon, a lever pivoted upon the case and having one end pivoted to the cover and the other end pivoted to the lugs projecting beyond the lower face of the table, and arms pivotally connected at one end to the case and at the other to the ears below said table, whereby said table and cover simultaneously swing upon pivotal centers when the cover is opened or closed, in combination as set forth.

In witness whereof I have hereunto set my hand this 21st day of May, 1892.

ALEX. T. BROWN.
