VENTILATED SPRING-CUSHlON FOR VEHICLES AND FURNITURE.

SPECIFICATION forming part of Letters Patent No. 333,557, dated January 5, 1886.

Application filed January 16, 1885. Serial No. 153,056. (No model.)

To aZZ whom, it may concern.-

Be it known that we, E. RIPLEY SIBLEY and HARLAN P. \VELLs, of Salisbury,in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Ventilated SpringOushions for Vehicles and Furniture, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

This invention has for its object the production of a cushion for vehicles, furniture, and analogous uses, which shall be perfectly venti' lated, and while flexible and yielding, yet permanently retaining its form and elasticity; and it will, in connection with the accompanying drawings, be hereinafter fully described and claimed.

In said drawings, Figure 1 is an inverted or under side plan view of a carriage-seat cushion embodying our invention. Fig. 2 is a front edge elevation of the same, shown as in its normal position. Fig. 3 is a central transverse vertical secti0n,taken as on line 00, Figs. 1 and 2, and as looking to the lefttherein, the parts beyond said line being shown in elevation. Fig. 4 represents the cushion as in position for use in a carriage-seat. Fig. 5 is a detached plan view of one of the springsupporting sockets. Fig. 6 is a vertical section through said sockets taken as on offset line Z, Fig. 5. Fig. 7 is a vertical section, and viewed as from the left therein, and showing a modification in the spring-supporting irons. Fig. 8 is an under side plan view of one of the upper supports of the springs at the center of the frame. Fig. 9 is a longitudinal vertical section through the same. Fig. 10 is a view similar to Fig. 8, but showing corner springsupport.

In said views, a a represent the side bars of the lower frame, they being united at their ends with end bars,b b, thus forming a rectangular lower frame. Two side bars,a a,somewhat longer than bars a, are at their ends united with end bars, I) b, thus forming a second or upper rectangular frame. Said bars a and b are at the respective corners of the lower frame secured together by means of flanges e ofthe spring-sockets d, Fig. 5, which are inserted in slots or kerfs cut in said bars,

as shown in Figs. 2, 3, and by rivets that secure the several parts together. Said springsockets are formed with a circular vertical wall, having an internal flange, 9, inside which is a circular opening, f, for escape of water, whiclnwhen employed in open vehicles, might fall therein, the base of the volute springs jbeing, as shown, seated inside said circular wall and resting on said flange g, as shown in Figs. 3 and 7. Said bars a and b are at the respective corners ofthe upper frame.

secured together by the flanges h of the top supports,p, of said springs,these flanges being inserted and secured in slots or kerfs cut in said bars, in the same manner as are flanges e, of sockets d, as above described. Upon the under side of said spring-supports p is formed a feather, a, to enter the axial opening in the top end of springs j and secure the same in position. When said spring-sockets d and stays p are employed for springs, other than at the corners of the frame, the securing flange is formed straight-tl1at is, without an angleas shown at h, Fig. 8, as it is only secured to the side bar. The frames being thus secured at their respective angles, the volute springs j are seated in sockets d of the lower frame, and the feathers t" of supports of the upper frame being seated in the axial passage in the springs, the two frames are then in proper relation, as shown in Figs. 1, 2,3; and to so secure them the stay-straps q, of leather, canvas, or other yielding material, are secured to the bars of the upper and lower frames, to slightly compress the springs, in order that when not in use the parts shall not be disconnected. When thus assembled, a strong canvas covering, it, tightly stretched, is secured at its edges to the bars a b of the upper frame, to cover the same, and over this may be laid the elastic filling Z, of curled hair or other material, which is covered by cloth or leather m, and if employed in a vehicle a front curtain, n, is secured to the upper bar, a, as shown. 1f the cushion be short, only the springs at the corners will be requisite; but for carriage seats of usual size a pair of intermediate springs, as shown in Figs. 1, 2, are necessary, the size of the cushionv and strength ofthe springs determining the'nnmber of the latter which should be employed.

Instead of inserting the fianges eh of the spring-supports in the bars, as shown, the same may be arranged as shown in Fig. 7, where flange e is above and flange it below the rails, yet without materially diminishing the scope of vertical play of the springs.

To prevent drawing together of bars a by the action of canvas 70, when weighted, a bar, 0, is secured to said bars, and between them it is dropped to allow yielding of the cushion without contact with said bar.

In said drawings we have shown our cushion as adapted to a carriage-seat; but it may be with equal facility adapted to all kinds of upholstered furniture, and by reason of the unobstructed air-space between the upper and lower frames it is cool, cleanly, and well ventilated.

\Ve are well aware of United States Letters Patent No. 179,257, dated June 27, 1876, and

No. 94,179, dated August 31, 1869, and we claim nothing shown, described, or claimed therein, onrinvention differing therefrom in that while said earlier patent has an upper and lower frame with connecting flexible stays and a cushion, yet its springs are of the class termed grasshopper springs, while in the latter patent there are no vertical flexible stays, and the volute springs are steadied by rigid rods, whiclnwhen the springs are compressed, must project in thesame degree beyond one or both of the frames.

' \Ve claim as ourinvention- 1. The combination of the upper and lower frames, the spring-seating cup-like supports 02, secured to the lower frame, the springsteadying plates 19, secured to the upper frame and formed with plate h and projection ii, to enter the top of the spring, the volute springs j, and flexible stays q, all substantially as specified.

2. The combination of the upper and lower frames formed with bars a b and a I), respectively, the spring base-sockets d, and supports 19, respectively secured to said frames, volute springs yielding stays q, covering 7c, and an overlying cushion, all substantially as specified.

3. The combination, with the volute springs and supporting-frame, of the metallic spring basesupports formed with flange 6, adapted to secure together the side and end bars of the frame, and with a vertical circular rim to receive the base of the spring, abottom, g, to support the spring, and an opening, f, for the escape of water therefrom, all substantially as specified.

4. The combination, with the volute springs and frame, of spring stay-plates 1), formed with wing h, to be secured to the bars of the frame, and with projection i,to enter the axial passage in the spring to steady the same,sub stantially as specified.
