J., assignor to Dri-Fast Process Corp., New Brunswick, N. .L, a corporation of New Jersey Application January 25, 1947, Serial No. 724,410
The invention relates generally to resilient connectors and has particular reference to such connisms in presses and like machines, extension springs have been used and have generally been found unsatisfactory because of compound stresses being set up which this type of spring cannot satisfactorily handle. Under these circumstances, it has been found impossible to keep the extension springs equally loaded due to lateral movements of the springs which caused them to fail. It is an object of this invention therefore to employ a type of spring which will not have these defects and which is related to suitable structure which will prevent lateral displacement and its consequent objectionable results.
It is a further object to provide a simple structure which is much more easily adjusted, in which maintenance is reduced to a minimum, and in which the recoil action is much more positive.
A further object is to provide a simple, strong, durable, efiicient device which is adaptable to be designed for the proper use of it with a wide variety of load conditions.
Further and more specific objects, features, and advantages will more clearly appear from a consideration of the specification hereinafter set forth especially when taken in connection with the accompanying drawings which illustrate a present preferred form which the invention may assume and which forms parts of the specification.
In brief and general terms, the invention comprises a compression spring device mounted on a housing which is provided with adjustable means to vary the tension in the spring device and also with simple and efiicient means for guiding the spring device in its movement under compression to prevent lateral or axial displacement whereby its efficiency is maintained constant, with perfect alignment.
More particularly the invention comprises two connector elements which are to be relatively moved, the one supporting a housing on which is mounted a resilient recoil device the parts of the housing acting to tension and guide the resilient device and the other connected to a compression plate acting against one end of the resilient device to compress it as the connector is moved in the recoil action of the machine to which it is connected.
The present preferred form which the inven- 1 Claim. (Cl. 267-70) 2 tion may assume is illustrated in the drawings, of which,
Fig. 1 is a side elevation, partly in section, through one form of connector device;
Fig. 2 is a similar view through a modified form of device; and
Fig. 3 is a horizontal cross section taken on the line 3-3 of Fig. 1.
In the preferred form shown in Figs. 1 and 3, there are two connector elements in the form of rods l0 and II the latter of which is adapted in any suitable manner to be connected to a fixed part of a machine and to be permitted to pivot or swing thereon in any desired manner (not shown) and the former of which is connected to a moving part of the machine such as a recoil mechanism (not shown) and adapted to move therewith.
To the lower or relatively fixed connector ll there is connected a housing formed of spaced plates l2 and [3 between which extend a plurality of tension elements such as rods l 4 which are provided with adjusting means such as nuts l5 threadable thereon to vary the distance between the plates and therefore to alter the normal tension and position of the compression spring I6 which is wrapped around the rods. This spring bears against the under face of the upper plate I2 of the housing and against the upper :face of an intermediate compression plate I! which is apertured to slide along the housing rods and is connected to the upper connector element III.
In this form it will be seen that as the movable connector Ill tends to move away from the other connector II, the plate I! or compression member connected thereto will move to compress the spring l6 and resist the movement but at the same time the nature of the housing constituted by the rods It will maintain the spring in proper axial alinement at all times and therefore will result in a definite determinable resistance of the spring to compression. Thus the spring in its reaction to compression is guided not only in its compressive motion but also against axial or lateral displacement and therefore there is avoided all the objectionable features of such lack of control formerly encountered in the employment of uncontrolled and guided springs.
In the form shown in Fig. 2 the action is substantially the same except that for heavier loads there is provided a second spring I 3 extending between the plate I 2 and the plate I 1 but coiled within the area defined by the guide rods l4. This multiple springs acts in the same manner as above described and is adapted to effectively react with heavier loads when required.
Thus there has been rovided a simple, efiicient, strong, durable device which can be adjusted easily, maintained within minimum expense, and which is adapted to cooperate with a wide variety of loads. It is one in which the compressive resistance of one or more springs is employed instead of their extensive reaction and in which they are'mounted on a housing-connected to one of the relatively movable elements which housing not only acts as a controller of their normal tensive position but also to prevent any axial displacement while under stress.
While the invention has been described'in'd'etail with respect to present preferredi'forms which the invention may assume, it is not to' be limited to such details and forms since many changes and modifications may be made in the-invention-without departing from the spirit and scope of'the invention in its broadest aspects. Hence itis desired to cover any and all forms and modifications of the invention which'may come within the language or scope of the appended claim.
WhatI claim asmy invention is:
A resilient connection comprising, a relatively fixed connector rod, a movable connectorrod, a
housing connected to the fixed rod amiucompriS- ing'threespaced disks'connected'by guide rods,
the disks beingmovable on the guide rods-,-a compression spring closely encircling the guide rods rod and being located between the two remaining disks,.the guide rods operating to prevent lateral distortion of both springs.
