or less successfully been tried in order to yieldingly support axle-bearings in centrifugal machines. At first, one or more spiral sprlngs were placed in the bearing, said spring or springs being wound around the same, or the spiral spring itself formed the bearing, in which case it was wound from a flat wire. Also spiral springs extending radially in relation to the bearing and several other constructions com rising springs have been used, but either tl fey have been expensive in manufacturing and diflicult to repair, when the springs break, or they have not served their purpose inasmuch as they have been more or less insensitive and generally not durable.
The object of this invention is to provide a box-bearing for centrifugal machines, in which the form of the spring insures sensitiveness in combination with great durability.
The invention consists, chiefly, in that the spring placed between the axle-box and the inside of the s ring casing forms a folded band bearing a ternately on the box and on the outer casing in suche manner-that one of two branches of each part of the spring lying between two adjacent points of contact of the spring with the casing extends in a direction substantially tangential to the box, while the other branch connecting two subsequent tangential parts forms an acute angle with the former one. The branch of the spring connecting the tangential part with the subsequent one may, suitably, bear on the latter so as to be yieldingly supported thereby. By this means a very gentle yielding is obtained which is uniform in all directions round about the box.
In the drawing, Figure 1 is a horizontal section of a box bearing embodying the invention. Fig. 2 is a similar view of a somewhat modified construction.
Referring to Fig. 1, the spring is made in one piece and bent in such a manner that one of the two arts at and b forming together a wave or fold has such a position in relation to the box as to be bent or caused to yield sidewise, when the box moves laterally, and at the same time glide against the box. The other part, which is suitably S-shaped, extends, on the contrary, in a substantially radial direction and is ex osed to compression between the'box an the outer casin The part a, thus swings about the fixed fuT crurn 0, while the part b is compressed, and at the same time a gliding motion takes place between the part a and the box (Z, and such a gliding and yielding motion also takes place between the other parts a of the spring and the box' The spring illustrated in Fig. 2 is bent in substantially the same manner as that shown in Fig. 1. The only difference is that the inner portion of each of the parts I) is in con tact with and bears on the adjacent part a.
This form of construction is far more advantageous than that shown in Fig. 1 as the spring, as a whole, will. be more expansive, due to the fact that the two parts a and 1) bearing oneach other are, thereby, made to better cooperate with each other.
Having now described my invention, what I claim as new and desire to secure by Let ters Patent is:
1. In a box-bearing, the combination of an axle-box, a casing surrounding the said box, at a distance therefrom, and a s ring in the sha e of a ribbon placed on ed e etween the casing and the box and folde so as to bear alternately on the box and on the outer casing in such a manner that one of the two branches of each part of the spring lying be tween two adjacent points of contact of the spring withthe casing extends in a direction substantially tangential to the box, while the other branch connecting two subsequent tangential parts forms an acute angle with the former, substantially as and for the purpose set forth.
2. In a box bearing, the combination of an axle-box, a casing surrounding the said box, at a distance therefrom, and a spring placed between the casing and the box and forming a folded band bearing alternately on the box and 011 the outer casing in such a manner that one of the two branches of each part of the spring lyin between two adjacent points of contact of t e spring with the casing extends in adireetion substantially tangential name to this specification in the presence of to the box, 'vghile the ether brancfh gennefiztttvd subscribing Witnesses. in two su sequent tan 'entia ranc es Y a foi ms an acute angle with the former and ALGOT LEVIN OHRIbTmSOm 5 bears on the subsequent tangential part, subl Witnesses:
stantially as and for the pu ose set forth. SIGURD DAHL,
In testimony whereof I ave signed my ERIK LUNDBERG.
