DAVID R. COLLIER, OF GARDNER, MASSACHUSETTS, ASSIGNOB T COLLIEB-KEYWORTH COMPANY, OF GARDNER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

SANITARY NURSERY-CHAIR.

' To all whom it may concern:

Be it known that I, DAVID R. COLLIER, a

of Gardner, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Sanitary Nursery-Chairs, of which the fol lowing is a specification.

The OlOJBQt of the present lnvention is to provide a sanitary nursery chair which 18 capable of being folded so that it may be easily carried or stored in a small space.

Of the accompanying drawings which illustrate one form in which the invention may be embodied: Figure 1 represents a side elevation of the chair in open position ready for use. Fig. 2 represents a rearelevation of the same. Fig. 3 represents a horizontal section in the planes indicated by line 3-3 of Figs. 1 and 2. Fig. 4 represents a vertical. section, on a larger scale,

looking toward the rear from the plane indicated by line 1-4:- of Fig. 1. Fig. 5 represents a side elevation of the structure included in Fig. 1. Fig. 6 represents a perspective view of the structure shown by Fig. 5, omitting the portion of the seat which is included in Fig. 5. Fig. 7 represents a perspective view of those portions of the stationary frame structure which are included in Figs. 5 and 6. Fig. 8 represents a perspective view of the movable elements included in Fig. 8, the same being shown in the position corresponding to closed or folded condition of the chair. Fig. 9 represents a side elevation of the chair in folded condition. Fig. 10 represents a rear elevation of the chair in folded condition.

The same reference characters indicate the same parts wherever they occur.

The main seat of the chairis indicated at 12; The seat is afiiXed to a substantially rectangular frame which comprises side bars 13, 13, afront bar 14, and a rear bar 15. (See Fig. 2.) The ends of the rear bar are connectedto the rear ends of the side bars by corner pieces 16; One of these corner piecesis shown in detail by Fig. 7.

The legs of the chair are indicated at 17. For the purpose of attaching the legs to the seat frame just-described, the forward ends of the side bars 13 are bent downwardly; as indicated at 18, and the corner pieces 16 are providedwith depending por- Specification of Letters Patent.

tions 19. The front legs 17 are connected to the portions 18 by pivot studs 20, and the rear legs 17 are connected to the POT. tions 19 by pivot studs 21. The axes of these pivot studs are substantially in alinement with each other. The lower ends of the legs are curved, as indicated at 17 for the purpose of giving a neat appearance and for the additional purpose of extending the base from front to rear. Each front leg is connected with the corresponding rear leg bya connecting portion 22. Forconvenience in manufacture, the two legs and connecting portion on each side are made from a continuous strip or bar. The pivotal connections between the legs and the seat frame enable the legs to swing under the seat to the position shown best by Fig. 10. The rear legs are provided with stop pins 23 which are adapted to abut against the lower ends 19 of the corner pieces when the legs are opened for use, for the purpose of limiting the opening movement of the legs. Figs. 2 and 4 show these stop pins engaging the portions 19*.

1 A back-rest or support isindicated at 24;. This back-rest is carried by a swinging frame 25 which is connected to the corner pieces 16 by the pivot studs 26. The swinging frame is adapted to swing forwardly and downwardly from the position shown by Fig. 1 to the position shown by Fig. 9, so that the back will lie closefto the seat. The swinging frame 25 is shown as being made of a strip or rod which is bent to the form resembling an inverted letter U, the horizontal connecting portion indicated at 25 (see Fig. 2) affording a convenient handle whereby the frame may be grasped to open or close the same and whereby the chair may be carried. The ends of the rod are fixed to plates27 which constitute plates 27 are provided with cam slots 28 whose function is to open and close the legs when the back is opened or closed. These cam slots are occupied by studs 29 (see Fig. 8) which have heads 30 at their outer ends. The cam studs are connected with the rear legs by links 31. Connecting pieces 17 are afliXed to the rear legs by means ofthe pivot studs 21 and stop pins 23 to afford convenient means for providing the desired connection wit-h the links 31.

The cam plates 27 are adapted to move the studs 29 vertically and thus swing the legs in the manner hereinbefore explained. The movements of the stud 29 are guided by the corner pieces 16 which are provided with vertical slots 32 through which the studs extend. The ends 28 of the cam slots which are farthest from the pivots 26 are substantially concentric with relation to the pivots. hen the back and legs are folded as shown by Figs. 8 and 9, the cam studs 29 occupy the portions 28 and the legs are thereby locked in folded position so that their weight will not have any tendency to open the chair.

Swinging arm rests are indicated at 33. These arm rests are preferably made of strips of flat metal whose ends are bent downwardly as indicated at 34. The lower extremities of the portions 34 are mounted upon pivot studs 35. The pivot studs at the front are carried by pieces 36 which are affixed to the rectangular seat frame. The pivot studs 35 at the rear are mounted in the corner pieces 16, as shown by Figs. 2, 4

- and 6. hen the arm rests are open for use they are locked to the back frame by latches 37. These latches are connected to the sides of the back frame by pivot studs 38, and they are provided with projections 39 which are adapted to enter suitable openings formed in locking pieces 40 aflixed to the arm rests. Springs 41 anchored to the back frame and connected to the latches normally hold the latter in locking position. When it is desired to fold the chair, the arm rests are folded inwardly before the back and legs are folded. Fig. 10 shows the arm rests extending toward each other and overlapping each other in folded position directly over the seat.

Side guards are indicated at 42. The lower edges of these guards are pivotally connected to the seat, and the upper edges are connected to the arm rests so that the guards will open and close with the arm rests. For the purpose of connecting the guards with the seat, the lower edges of the guards are provided with strips 43 whose ends are turned inwardly as shown by Figs. 2 and 9. These ends are mounted upon pivot studs 44 which are supported by brackets 45 affixed to the seat. The axes of the pivots 44 are substantially in alinement with the axes of the pivots 35 which connect the arm rest with the seat frame. The arm rests are provided with slots 46 (see Fig. 9) for the reception of a strap or guard 47 which may extend across from one armrest to the other to prevent the occupant of the chair from falling forward.

then the chair is open for use there is sufficient space beneath the seat and between the legs for the reception of a vessel such as that indicated at 48 in Fig. 2. The seat 12 is provided with an opening 49 the outline of which is represented by dotted lines in Fig. 2. A collapsible screen for concealing the vessel is anchored to the bottom of the seat 12 and to the connecting pieces 22 which connect the legs. This screen is shown as comprising side pieces 50, 50, of suitable flexible sheet material, and a front piece 51 of similar material. The upper edges of the front and side pieces may be secured to the bottom of the seat by any suitable means, such as tacks. Fasteners indicated at 53 serve to connect the lower edges of the side pieces to the connecting pieces 22. The vertical meeting edges of the front and side pieces are joined, as by stitches or any other desired means. A rear flap or screen, indicated by dotted lines 54 in Fig. 1, may be used to conceal the vessel from the rear, but this flap may be omitted if desired. The vertical meeting edges of the front and side flaps 50 and; 51 are preferably joined, as by stitches or otherwise; and if the rear flap 54 is used, the same may be likewise oined with the side flaps.

An auxiliary seat is indicated at 55. This seat may lie upon the seat 12 when desired and is adapted to cover the same so that the opening 49 will not be apparent. As shown by Fig. 2, the rear edge of the auxiliary seat is connected by hinges 56 to the seat 12. lVhen it is desired to uncover the seat 12 the auxiliary seat may be swung upwardly about its hinges so that it will rest against the back 24.
