Patented Feb. 24, 1931 HARRY R. MCMAHON, OF CORAOPOLIS, PENNSYLVANIA, ASSIGNOR 'I'O STANDARD STEEL SPRING COMPANY, A CORPORATION OF PENNSYLVANIA BUMPER END CONSTRUCTION Application filed July 17, 1930. Serial No. 468,615.
This inventionrelates to a bumper end construction of the same eneral type as that disclosed in my copen mg application Serial N 0. 468,614, filed July 17, 1930, for a Bumper end construction (Case A).
Both in the aforesaid application and in the present invention the construction is such as to avoid edge bends which are recognized as hitherto accepted disadvantages inherent in many types of bumper construction, the same being a relatively difficult and also a relatively expensive procedure.
The present invention is an improvement over my copending application in that a certain simplification of parts has been eiiected, at the same time cient construction.
An object of the present invention is the reconstruction of a bumper end assembly so as to provide a minimum of parts and a maximum of simplicity.
Another object of the invention is the provision of a bumper end construction wherein the bumper bar ends are formed into concentric inner and outer cylinders, the rear bar having the smaller narrower cylinder generally, which fits within the wider and thicker cylinder formed at the end of the single front or im act bar.
A urther object is the elimination of a spacing member and a contouring of the outer cylinder so as to receive efliciently the inner cylinder and at the same time form a shoulder which rests upon the upper edge of the,
rear bar.
Other and further objects will be understood frommy copending application and by those skilled in this particular art orwill be pointed out hereinafter.
In the accompanying drawings: 7
Figure 1 is'a plan view of a bumper end construction embodying the present improvement. I Fig.2 is an elevational view of Fig. 1;
Fig. 3 is a cross section on the line IIIIII of Fig. 1: and v Fig. 4 is a perspective view of the foregoing embodiment, p
In the drawings, and referrin to the elements illustrated therein in detai the single providing an unusually efiifrontor impact bar 10 is formed with a cyliner at its end and similarly the rear bar 11 is formed with a cylinder at its end, the various comments as to size and proportions referred to in my aforesaid copending application being of equal force here.
The larger cylinder formed at the end of the single front or impact bar 10 is, however, provided with a cut-out portion 12 extending vertically from the bottom of the cylinder to a point near the top and then horizontally to the end of the cylinder, thus leaving a shoulder, the function of which will be more fully explained hereinafter.
The cut-out portion 12 permits the insertion of the smaller second cylinder from the bottom of the larger cylinder until the upper edge of the rear bar abuts the shoulder which prevents further movement. The formation at the upper end of the larger cylinder in addition to the functions already described acts as a substitute for the upper spacer member of my copending application, there being necessary, therefore, only one spacer 18 at the bottom in the location shown.
The usual lock washers 17 and bolt 13 with enlarged head 14 and nut 15 are provided as shown and as understood without repetition here as is also the lock washer 16, with or without intermediate washers.
The construction shown provides for a very simple assembly and an equally readily disassembly when required. When assembled a very simple, but efiicient construction is provided allowing for necessary relative movement of the parts when the front bar is impacted. The cylinders as shown are coiled in opposite directions due to the fact that the ends of the respective bars are oppositelybent; This has the advantage of keeping the portion of the rear bar adjacent its cylinder from too close proximity to the similar portion of the front bar, thereby preventing undue wear. It also has the advantage of so spacing and positioning one bar with respect to t e other that each will have a more or less independent shock resisting resiliency. What I claim as new and desire to secure by Letters Patent is:
1. In a bumper construction, a her having an end with a slotted cylinder, and a second bar having an end formed and coiled cylindrically in a direction opposite to said first cylinder and disposedwithin said first cylinder.
2. In a bumper construction, a bar having an end with a cylinder, said cylinder having a cut-out portion forming a slot and a shoulder near the top of the cylinder, andxa second bar having an end formed cylindrically and disposed within said first cylinder and passing through the slot thereof, and its upper edge abutting said shoulder.
3. In a bumper construction, an impact bar having its ends bent to form cylinders, said cylinders each having a cut-out portion and ashoulder near the top of the cylinder, and a rear bar having its ends passing through said slots and its upper edge abutting said shoulders, the ends of said rear bar being bent to form cylinders, and a bolt assembly maintaining the aforesaid elements in suchposition.
4. In a bumper construction, an impact bar having its ends bent to form cylinders, said cylinders each having a slot and a'shoulder near the top thereof, and a rear bar having its -ends passing through said slots and its upper edge. abutting said shoulders, the ends of said rear bar being oppositely bent to form cylinders within the first cylinders, and a bolt assembly including a spacer and lock washers for maintaining said elements in such position.
5. In a bumper end construction, two substantially concentric cylinders as the termini of front and rear bumper'bars, each of said cylinders being coiled 'n opposite directions for spacing said front and rear bars, and means for detachably securing said cylinders in operative association.
6. In a bumper endiconstruction, two cylinders as the termini of front and rear bumper bars, one cylinder having an external shoulder and slot and the other cylinder being internal of the first, the portion of the bar adjacent the internal cylinder passing through said slot and having its edge abutting said shoulder, and means for detachably securing said cylinders in such relation.
7. In a bum er construction, a bar having its ends coile into cylinders, a second bar having its ends coiled in a direction opposite to said first cylinders and concentrically thereof, said cylinders of the first of said bars having a cut-out portion forming a slot and a shoulder, an edge of said second bar being disposed to abut against said shoulder.
8. In a bumper construction, an impact bar having its ends bent to cylinders each having a cut-out portion and a shoulder near one end of the cylinder, and a rear bar having its ends passing through said slots and its upper edge abutting said shoulders, the ends of said rear bar being form cylinders, said bent to form cylinders disposed within the cylinders of said impact bar.
9. In a bumper construction,-an impact bar having its ends bent to form cylinders, said cylinders each having a cut-out portion and a shoulder near one end thereof and a rear bar havingits ends passing throu h said slots and its upper edge abutting sai shoulders, theends of said rear bar being bent to form cylinders, and a detachable assembly maintaining the aforesaid elements in such position.
10. In a bumper construction, an impact bar having its ends bent to form cylinders, said cylinders each having a cut-out portion and a shoulder near one end thereof, and a rear bar having its ends passing through said slots and one of its edges abutting said shoulders, the ends of said rear bar being bent in a direction opposite to said impact bar cylinders and being disposed therewithin.
In testimony whereof, I have hereunto subscribed my name this 14th day of July, 1930.
HARRY R. MOMAHON.
