side, such visibility is imperfect and they do not permit of the piece of meat being manipulated. bested with gravy, turned over etc. It is therefore necessary to open the oven door and there is consequently a considerable loss of heat due to the outlet of hot air and the.inlet of cold air, even if the door is simply placed ajar, since the communication of the inside of'th'e oven with the outer air not only takes place through the top of the doorway. but also through the sides.
' The present invention has for its object to avoid this waste, by using a door which can not only open like an ordinary door by swinging, but can also slide by moving downwardly in its plane, so as to leave an opening at the top. It can remain in this position as long as desired; the width of the opening thus obtained can moreover he made as small as desired.
This operation is obtained bymeans of guide grooves wherein the hinge pin passes so that the the lower pin and against the upper edge of the door. A spring tends to bring the parallelogram 35 back to its initial shape and it is suitably calculated so that the weight of the door is balanced. and the door remains aiar in theposition in which it has been placed without continuing its sliding movement. 4o, The accompanying drawing shows an oven door according to the invention in various positions. In said drawing: Figs. 1 and 2 show in front elevation and in section, a door in the closed position. I 45 Figs. 3 and 4 show in front elevation and in section. the same door which has slid slightly.
Figs. 5 and 6 show in front elevation and in This on the sides of the door are provided slots 4 I through which the pin 2 passes so that the door can move downwards more or less by sliding in its plane. To slide the door, a downward pressure is exerted on the handle 6.
In the body of the door is lodged an articulated parallelogram l, the top corner 8 of which abuts against the upper flange 9 of the door and the lower corner Ill against the pin 2. Suitable stops prevent said corners 8 and ill from escaping m sideways.
A spring H which is suitablyf. calibrated, balances the weight of the door. The latter therefore remains in the position which has been given it, as for example that of Figures 3 and 4, 5 and 6. 15-
In Figures 3 and 4, there is a small opening, as at 5 for ventilation purposes.
If it is desired to watch and manipulate the objects placed in the oven, the downward movement of the door will be'continued by pressing 20 on the handle 6 and the opening will be greater.
as seen at l2 (Figures 5 and 6) where the door is in its extreme position.
' To close it again, it suifices to exert a slight upward pressure on the handle 6, since the spring brings back the arms of the parallelogram and it suflices to overcome the frictional forces.
1. An oven door comprising a frame provided with slots, a door plate having a hinge at its bottom end, a hinge pin, and resilient means to hold the door plate in equilibrium; the aforesaid elements being so constructed and arranged that the door plate may be either swung outwardly around the hinge pin, or slide downwardly in its :5 plane without simultaneously swinging outwardly; said resilient means for holding the door plate in equilibrium enabling the door plate to remain in whatever position is given to it, whereby an opening of variable height may be provided a the top.
2. An oven door according to claim 1, having slots in which the hinge pin is adapted to slide, the resilient means comprising four metal rods and a spring arranged to form an articulated l6 parallelogram in the body of the door, which abut against the lower pin and against the upper edge of the door. said spring means tendingto bring the parallelogram back to its initial position and calculated to balance the weight of the door.
