FLEXIBLE CASING FOR VEHICLE SPRINGS Filed March 28, 1929 4 INVENTOR ATTORNEY Patented Apr. 26, 1932 FLEXIBLE CASING FOR SPRINGS Application filed March 28, 1929. ,iSerial No. 350,508.

This invention relates to flexible casings for vehicle springs of the leaf type and has for its object to provide a casing which is inexpensive to manufacture, yet which is durable and efiectively prevents the entrance of dirt or moisture While retaining the lubricant about the spring.

A further object is to provide the casing with novel oiling-means for supplying oil to and distributing it along the spring.

A still further object is to provide novel means for securing the edges of the casing together to hold it about the spring.

In general the invention resides in all the novel features of construction of the spring casing herein disclosed and particularly set forth in the appended claims.

In the drawings Fig. 1 is a side elevation of the casing secured in place about a spring;

Fig. 2 is a bottom plan view of the spring casing showing how the edges are secured together; Fig. 3 is a transverse section through the casing and oil reservoir on line 3-3 of Fig. 1; Fig. 4: is a fragmentary longitudinal section through the device on line 44 of Fig. 3.

In the form of my device illustrated in the accompanying drawings. 10 designates the casing broadly, which is preferably constructed of a water proof fabric and comprises a main portion 11 and a flap portion 12. The main portion 11 of the casing is made of a single piece of material slightly wider at one end than at the other, with its side edges provided with hems to receive resilient wires 13 for the purpose hereinafter set forth. Through the middle of the portion 11 are two parallel tucks 15 spaced apart the width of the spring on which the cover is to be used. Where the cover is to be used on springs which have clips to prevent separation of the leaves the tucks 15 are not stitched at that point so that an excess of material 16 is left to fit about these clips.

The tucks are made with the folded portion on the inside of the casing, so as to pro vide a channel in which is positioned a strip of felt or other absorbent material 17 which extends the length of the casing which is clamped to the top of the spring when the casing is secured in place, Across each end there is secured to the inner side of the portion 11 felt strips 18 which absorb any excess oil that may run along the spring and which serve to more effectively seal the ends of the casing about the spring to prevent the entrance of dirt;

At one side, either as a continuation of the material from which the portion 11.is made, or as a separate piece attached thereto is the flap 12 over which the opposite side of the portion 11 folds when the casing is see cured about a spring. The flap closes the space between the edgesof the cover portion 11 which are arranged underneath the spring.

An oil reservoir 20 having the form of a long fiat opentop pan is secured by rivets 21 with its open top against thefelt strip 17 and is arranged to extend between the tuck 15 with its fiat bottom resting on the top of the spring about which the casing is secured. A suitable oil inlet member 22 is provided in the casing 11 above the reservoir 20 so that oil may be supplied .to the reservoir from. time to time, the spring pressed pivoted cover 23 which is normally closed prevents the entrance of dirt therethrough- To secure the casing about the spring one side of the portion 11 just behind the wire member 13 is provided with hooks 25. The opposite side is provided with short flexible wires 26 each of which has one end secured about the wire 18 in that side.

When the casing is engaged over a spring the fiap 12 is folded under the free edge of the body portion 11, and the sides of the portion 11 are drawn together and the'wires 26 secured about the respective hooks 25. The wires 13 distribute the pull of the Wires on the hooks 25 throughout the length of the cover and permit the cover to accommodate itself to whatever shaped spring it is secured about, since the wires 13 are capable of being flexed in any direction, allowing for i springs of various curvatures as well as permitting the sides to be drawn closer together in some places along the length of the casing than in others to allow for irregularity about the spring, such as clips, etc.

Having thus described my invention, what I claim is:

1. A flexible casing for vehicle springs comprising a flexible body portion, means for securing it about a spring, a strip of absorbent material extending longitudinally of said casing and adapted to rest on the upper surface of the spring, an oil reservoir comprisin a fiat pan member open at one side, secure to the underside of said absorbent strip with its open side thereagainst and with its flat bottom adapted to rest on the spring, said casing being provided with an opening above said reservoir through which oil may be supplied, and means for closing said opening.

2. A flexible casing for vehicle springs comprising a body portion, parallel seams extending longitudinally thereof with the excess goods folded to the inside, said seams defining the top edges of said casing when secured about a spring, and a strip of absorbent material positioned between said seams and extending the length of the casing, the excess goods forming a channel into which said strip fits. v

3. A flexible casing forvehiclespringscoinprising a body portion, parallel seams extending longitudinally thereof with the excess goods folded to the inside, said seams defining the top edges of said casing when secured about a spring, a strip of absorbent material positioned between said seams and extending the length of the casing, the excess goods forming a channel into which said strip fits, and an oil receptacle having one open side, secured with said open side against the under face of said absorbent strip, whereby oil which is placed in said receptacle will splash against said absorbent strip and be distributed along said spring.

' In testimony whereof, I hereunto aflix my signature.
