REVERSIBLE FOLDING SPRING-SEAT.

Application filed July 14,

To all whom it may concern:

Be it known that we, ANTON E. VICK- LUND and JAMEs B. GRoBnY, citizens of the United States, residing at Middle River, in the county of Marshall, State of Minnesota, have invented a new and useful Reversible Folding Spring-Seat, of which the following is a specification.

The present invention appertains genan improvement over the folding seat disclosed in our Patent No. 1,052,299 granted February 4, 1913.

It is the object of the invention to prov vide a seat structure embodying a novel and improved reversible means for supporting Specification of Letters Patent.

Patented Mar. 27, 1917.

1916. Serial No. 109,329.

The seat 1 is constructed of wood or other suitable material, and is provided with a back composed of a longitudinal bar 2 having its lower end hinged, as at 3, upon the seat 1 adjacent the rear edge thereof, and a bar 4 above and parallel with the bar 2 and attached thereto by means of connecting strips 5. The bars 2 and 4 can be constructed of wood, while the strips 5 are constructerally to vehicle seats, and is partlcularly ed of metal. In order to hold the back in raised position, a spring catch 6 is attached to the rear side of the bar 2, and is engageable with a keeper 7 secured upon the seat in rear of the back. WVhen the catch 6 is r lreleased from the keeper, the back can be jswung onto the seat, and when the back is the seat either above the wagon box orig iilraised, the catch 6 in engaging the keeper within the same, the seat in either case beingffw will hold the back firmly in place. End yieldably or resiliently supported for thefig plates 8 are hinged, as at 9, upon the seat comfort of the person or persons seated on. the seat. 7

% adjacent the ends thereof, and are adapted to be swung inwardly upon the seat to It is also the object of the invention to glie underneath the back when the back is provide a seat construction of the nature in-.

dicated which can be compactly folded when not in use, in order that it can be readily stored or carried.

A further object of the invention is to provide a seat construction having the characteristics indicated and which is comparatively simple, strong and inexpensive in construction, and which will be thoroughly practical, convenient and efficient in use.

With the foregoing and other objects in view which will appearas the description proceeds, the invention resides in'the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimedwithout departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein':-

Figure 1 is a rear view of the seat in its elevated position.

Fig. 2 is a plan view of the seat.

Fig. 3 is a fragmental detail illustrating the seat in its lowered position as when hung within a wagon box.

Fig. 4 is an enlarged sectional view taken on the H of Fig. 3.

swung forwardly and downwardly, to thus provide a compact arrangement. The end plates 8 are connected by chains or other flexible connections 10 with the ends of the bar 4, whereby when the back is swung upwardly, the chains 10 will swing the free portions of the plates upwardly, whereby to facilitate the unfolding of the parts.

The supporting means for the seat include a pair of transverse plates 11 bolted or otherwise secured to the lower surface of the seat 1 adjacent the ends thereof, and each of said plates is provided with a pair of upwardly projecting rigid hangers or arms 12 adjacent and projecting above the end of the seat, and the upper ends of the hangers 12 have bifurcated eyes or bearings 13. The hangers 12 are arranged adjacent the forward and rear edges of the seat, and a pair of supporting bars 14 is provided at each end of the seat. Certain ends of the bars 14 are pivotally mounted within the eyes or bearings 18 by means of pivot bolts 15, whereby said supporting bars 14 can be swung upwardly and downwardly around the ends of the seat.

The supporting bars 14 are provided with means whereby they can be applied to the sides of a wagon box or vehicle body in either a downwardly projecting or an upwardly projecting position. Thus, each supporting bar 14, which is preferably cast or forged from suitable metal, is provided with an integral tongue 16 parallel and approximately coextensive in length therewith, and with a second tongue 17 integral with the bar 14 and parallel therewith. The basal portion of the tongue 16 is united with the bar 14 adjacent the pivoted end thereof, and the tongue 17 is united with the bar adjacent the free end thereof, the two tongues being disposed at the opposite sides of the bar 14 and projecting in opposite directions. Thus, the tongue 16 projects from the pivoted toward the free end of the bar, while the tongue 17 projects from the free end of the bar toward the pivoted end thereof, and the tongue 17 is shorter than the bar 14 whereby the tongue 17 can swing un der the seat 1 when the bar 14 is swung downwardly. The tongues 16 and 17 provide oppositely extending or reversed hooks for U-shaped portions having the common limb 14. Thus, the bar 14 forms with the tongue 16 a hook or U-shaped portion which is open at the free end of the bar 14, and said bar forms with the tongue 17 a reversely disposed hook or U-shaped portion which opens toward the pivot of the bar. The edges of the bar 14 and tongue 17 are provided adjacent the basal end of said tongue and the pivoted end of the bar with curved lips or flanges 18 providing a socket. in which a co1led wire expansion sprmg 2O isseated, and the edges of the bar 14 and tongue 17 are provided adjacent the basal portion of the tongue 17 and the free end of the bar 14 with similar curved lips or flanges 19 providing a socket in which a second shorter coiled expansion spring 23 is seated. Plates or seat members 22 and 23 are provided against which the free ends of the springs bear. The plates are provided at their remote ends with slots 24 through which the respective tongues 16 and 17 project, and said plates are provided at their adjacent ends with T-shaped slots or recesses 25 slidably engaging the bar 14, whereby said plates are slidable longitudinally at the opposite sides of the bar and between the bar and tongues. The plate 22 is moved away from the pivot of the bar 14 by the spring 20, and the plate 23 is moved toward the pivot of said bar by the spring 21, and said plates have studs 26 upon which the respective ends of the springs are fitted.

In order to hold the supporting bars 14 firmly in place when they are swung to downwardly projecting position, as seen in Fig. 1, resilient catches 27 are attached to the bottom of the seat or to the lower surfaces of the plates 11 and project toward the ends of the seat to engage the ends of the tongues 17, whereby to hold the bars 14 in downwardly projecting position, and to prevent the vibration of said bars 14 and seat 1 relatively to one another in the elevated position of the seat.

When the structure is not in use, the plates 8 can be swung onto the seat 1, and the back can then be swung onto the seat and plates 8, after which the supporting members can be swung upwardly and inwardly onto the back, thus bringing the parts within small compass in order that the structure can be readily stored or carried. To apply the seatto the sides 28 of the wagon box or vehicle body, the parts can be readily swung into place, and if it is desired to support the seat 1 in elevated position, as seen in Fig. 1, the supporting bars or members 14 are swung downwardly whereby the said bars 14 together with the tongues 16 straddle the upper edges of the sides 28 with the plates 22 resting upon the upper edges of sides. The bars 14 and tongues 16 provide inverted U-shaped guides straddling the sides of the wagon box and movable vertically relatively to the plates 22. Thus, the weight carried by the seat 1 depresses the bars 14 and therefore compresses the springs 20, whereby the seat will be resiliently supported. The bars 14 are held firmly in place by means of the catches 27' which engage the ends of-the tongues 17 in this position of the structure.

When it is desired to hang the seat within the wagon box, as in cold weather to protect the occupant or occupants from winds, the bars 14 are swung to upwardly projecting position, as seen in Fig. 3, which reverses said bars so that the U-shaped portions provided by the bars 14 and tongues 17 are arranged to straddle the upper edges of the sides 28 of the wagon box with the plates 23 seating upon said'upper edges. In this position of the structure, the bars 14 provide hangers for suspending the seat within the wagon box, and said bars or hangers 14 are movable downwardly, which will compress the springs 21. V In this position of the parts, the springs 21 resiliently support the bars 14 and seat.

Having thus described the invention, what is claimed as new is:

1. A seat, supporting members pivotally connected therewith to be swung to downwardly and upwardly projecting positions and having reversed U-shaped portions to straddle the sides of a vehicle body in either position of said members, and spring means within said portions seating against the closed ends thereof and seatable upon the sides of a vehicle body for yieldably supporting said members in either position thereof.

2. A seat, supporting members pivotally connected therewith to be swung to downwardly and upwardly projecting positions and having reversed U-shaped portions to v away from the pivoted ends thereof and providing reversed U-shaped portions to straddle the sides of a vehicle body in either position of said bars, said bars and tongues having sockets at the basal portions of said tongues, and expansion springs seated in said sockets.

4. A seat, supporting bars pivotally connected with the ends thereof to be swung to upwardly and downwardly projecting positions, said bars having tongues upon opposite sides thereof projecting toward and away from the pivoted ends thereof and providing reversed U-shaped portions to straddle the sides of a vehicle body in either position of said bars, plates slidably engaging said bars and tongues, and expansion springs disposed between said plates and the basal portions of said tongues.

5. A seat, supporting bars pivotally connected with the ends thereof to be swung to upwardly and downwardly projecting positions said bars having tongues upon opposite sides thereof projecting toward and away from the pivoted ends thereof and providing reversed U-shaped portions to straddle the sides of a vehiclebody in either position of said bars, the bars and tongues having sockets at the basal ends of the tongues plates having slots engaging the tongues and having T-shaped slots engaging the bars, and coiled expansion springs seated in said sockets and bearing against said plates.

In testimony that we claim the foregoing as our own, we have hereto aifixed our sig natures in the presence of two witnesses.
