ELLEBY JOHNSON, OF BROOKLYN, NEW YORK.

TYPE-WRITER BEST.

Specification of Letters Patent.

Patented Apr. 30, 1918.

Application filed July 'i', 1916. Serial No. 107,986.

be more eflicient and convenient in use than those heretofore constructed and which shall have a general organization wherein a resilient or elastic action is inter osed between the typewriter and its S pporting table, desk or such and thus prevent the vibrations of the machine from reaching the supporting board of the desk which would, in the absence of my invention, tend to greatly magnify the sound resulting from the vibrations.

Furthermore I provide a the device by which the typewriter can be easily and quickly tilted out of the way to allow the surface of the desk to be readily cleaned of dust particles of paper, etc, which usually collect there.

Referring to the accompanying drawings Figure 1 is a side view of my device attached to a section of table or desk and supporting one side of a typewriter, there being one of the devices at each side' Fig. 2 'a section taken at m-w, Fig. 1; ig. 8 a plan view of the device proper and Fig. 4 a perspective view of a. leaf or flat spring having a corrugated spring superimposed thereon.

1 is a fulcrum-plate having at its rear end a pair of ears 2'and at its front end ears 2.

hinging action m Placed underneath, at each end, is a rubber cushion 3 and at the center is a clamp 4 secured to the desk b screws 5 which straddles the plate and olds it down upon the rubber cushions. The clamp has a pin 6 riveted thereto which tpasses downwardly through a hole in the ulcrum-p-late to retain it in position. 7 is a supporting bar having a channel-section formation and positioned above the fulcrum-plate and attached thereto by means of rivet 8 at its rear end and removable" pin 8. at its-front end. Centrally located uponthis bar is a flat or leaf spring 9 fastened. at its ends by rivets 10 and having slidably mounted thereon collars 11, the rivets being of sufiicient length to allow of frictional contact of the collars between the supporting bar 7 and leaf spring 9. Centrally located and secured upon the leaf spring is a corrugated spring 12 upon which the typewr'ter rests which is held down upon it by the screws 13, these screws entermg threaded holes which are commonly found in typewriters. These screws pass through holes in the supportm bar 7 and have he ical springs 14: interpose between the bar and washers resting upon the screw heads.

It will now be noted that the typewriter is entirely supported b spring elements tain of which are adjus ble as the collars 11 may be moved to any position, as at 15, thus changing the amount of resilience to suit difierent weights of machines; for the nearer the collars are laced to each other the stiffer the action or the leaf spring.

When wishing to clean under writer pin 8 is removed and the t pewriter with bar 7 raised,'hinging upon crum-pin or rivet 8, as shown by dotted line 16.

I claim:

1. In a typewriter rest the combination of a stationary member; a second member having its rear end pivotally connected with the said first member; resilient members carried by said second member and adapted to engage a typewriter frame and means for retaining engagement of said resilient members with a typewriter, substantially scribed.

2. In a typewriter rest the combination of a rigid support; a resilient member mounted thereon consisting of a flat spring for supporting atypewriter and a ustabIe members suppogtmg said spring, substantially as deas descri 3. In a typewriter rest the combination of a rigid support; a resilient member centrally located thereon and adapted to engage a typewriter; means for alteri the amount of resilience of said centrally ocated resilient member, and resilient members mounted upon the rigid support and adapted to engage the typewriter frame and oppose the action of the centrally located resilient member, substantially as described.

4. In a typewriter rest the combination of a supporting member; an adjustable resilient member mounted thereon; a'seoond resilient member carried by said adjustable resilient the ype:

member and adapted to engage a t ewriter frame to support same an means or holding the typewriter in contact with said second resilient member, substantially as de- 5 scribed.

5. In a typewriter rest the combination of a, supporting frame; a centrally located member having adjustable sup orts for engaging and receiving the weig t of a, typewrlter and resilient members connecting 10 each end of the said supporting frame with the typewriter, substantially as described.

In witness whereof I aflix my signature.

ELLERY JOHNSON.
