CHARLES RODERICK AND THERON L.

KNAPP, OF WOODSTOCK, ILLINOIS, ASSIGNORS TO THE OLIVER TYPEWRITER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

MEANS FOR SECURING TYPE-WRITERS TO BASE-BOARDS.

Specification of Letters Patent.

Patented May 8, 191?.

Application filed July 1, 1910. Serial No. 569,960.

United States, and residents of Woodstock,

in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Means for Securing Type- VVriters to Base-Boards;'and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to typewriting machines and is more particularly applicable to machines of the Oliver type in which the shift-frame is provided with two horizontal, transversely arranged guide-bars on which the paper-carriage rests and travels and in which said guide-bars project at their ends beyond the shift-frame proper and extend laterally outside of the frame where they are supported from a base-board beneath the machine frame. The type of Inachine referred to is illustrated in Letters Patent Number 904,207, of the United States, granted November 17th, 1908, to

I Theron L. Knapp.

The object of the invention is to provide simple and eflicient means for securing the machine frame to the base-board which will, at the same time, afford a cushion to decrease the shock and deaden the noise due to the operation of the machine and will accurately maintain said machine frame 1n its proper relation with respect to the supports for the extended guide-bars.

In the drawings Figure 1 is a top plan view of a machine of the type described, with the paper-carriage and type-keys removed and the vertical bars which support said type-keys shown in cross-section.

Fig. 2 is a partial vertical section on an enlarged scale through Fig. 1 on the line 22 thereof.

Fig. 3 is a vertical section through Fig. 1 on the line 33 thereof.

Fig. 4 is a partial vertical section on an enlarged scale on the line 4.-4L of Fig. 1.

Fig. 5 is a vertical section through Fig. l on the line 5-5 thereof.

As shown in the drawings, board; 11, the machine frame;

10 is the base- 12, the Shirt- 1d, the extended guide-rods for the paper-carriage which are connected to the shift frame and project laterally beyond the machine frame; and 15, 15, 15, 15*, the supports for the ends of the guide-bars said supports being secured to the baseboard. These parts are substantially as described in the patent referred to and need no further description as they form no part frame; 13,

- of the present invention.

The machine frame base 11 is preferably made hollow and has a top wall 21 and an upright flange 21 16, 17 18, 19, indicate toe-clamps which are secured to the baseboard 10 in position to engage against the upright flange 21 of the base 11 of the machine frame. Said toe-clamps are preferably arranged in pairs with one pair forward of and the other pair back of the transverse medial line of the machine, and with the toe-clamps of each pair in a line parallel to the guide-bars 13, 14. Each of said toe-clamps consists of an angular piece of metal having a horizontal member 16 which engages the top of the base-board, and an upright member 16 which engages the outer surface of the upright wall of the machine base. The horizontal members 16 are provided with holes for screws 22 by means of which they are secured to the baseboard. It is apparent that the toe-clamps form rigid abutments rising from the baseboard which will positively resist any tendency of the machine frame to twist or shift on the base-board in the operation of the shift-frame.

The base 11 is anchored or held to the base-board by the following means: In the vertical plane of the longitudinal central axis of the machine frame, near the front of the same, there is secured to the underside of the top 21 of the base, a lug 23, (see Figs. 1, 4; and 5). Said lug is preferably provided with lateral flanges 23 23 having holes or openings to receive screws 23", 23", which are threaded into the top 21 of the base. 24: is a recess opening through the bottom of said lug and internally threaded to receive the upper end of a threaded bolt 25 which projects upwardly from the base-board and is located in a vertical hole 26 in the baseboard. Said hole is enlarged at the bottom to form a recess 26 to receive the head 25 of the bolt and a washer 27 against which said head directly bears. The base of the lug 23 is substantially on a level with the lower margin of the upright flange 21 of the base and rests on' an elastic washer 28 interposed between its base and the top of the base board 10. This construction efficiently anchors or holds the machine base at this point to the base board and at the game time affords a cushion bearing for said ase.

Similar anchoring and cushioning devices are located at the rear of the machine at points spaced equally on each side of the longitudinal central axis of the machine base (see Figs. 1 and 2). In this case the upright wall of the base is preferably thickened at the point of anchorage to form a lug 33. Said lug is provided as before with a vertical internally threaded recess 34; to receive a vertical threaded bolt 35 which projects upwardly from a hole 36 formed in the base-board. 38 is the cushioning washer interposed between the base of the lug and the top surface of the base-board. On account of the increased depth of the upright flange 21 at the rear of the base, the bolts 35 may be made longer than the bolt 25.

It is apparent from the above description that the bolts 25, 35, 35 may be drawn home so as to efliciently anchor the machine to the base-board and hold it securely against overturning without impairing the efiiciency of the cushioning members 28, 38, 38, and that Copies of this patent may be obtained for five cents each, by addressing the any tendency of the machine to twist or shift on the baseboard, made possible by the elasticity of this anchorage, is prevented by the toe-clamps 16, 17, 1S and 19.

We claim as our invention The combination of a typewriting machine having a base portion providedwith substantially upright side walls and fastener lugs rigid with said base portion, a base board, cushioning members interposed between said lugs and said base board for holding said machine base out of contact with said board, fastener bolts extending vertically through said base board and said cushioning members and engaging said lugs to loosely secure said machine base to said base board, and a plurality of abutments rigidly secured to said base board and having upwardly projecting portions engaging the side walls of said machine base to securely hold the same against lateral movement while permitting a limited vertical movement thereof relative to said base board, substantially as described.

In testimony, that we claim the foregoing as our invention we aflix our signatures in the presence of two witnesses, this 17th day of June, A. D. 1910.
