CORNELIUS O PIETZSCH, OF EAST BEBNARD, TEXAS.
DRAFT ATTACHMENT FOR AUTOMOBILES. -Specification of letters Patent. Patented 1tar. 12, 1910.
Application filed May 1, 1917. Serial No. 165,708.To all whom it may concern:
Be it known that I, CoRELrus 0.
PIETZSCH, a citizen of the United States,
residing at East Bernard, in the county of
5 Wharton and State of Texas, have invent-
ed certain new and useful Improvements
in Draft Attachments for Automobiles, of
which the following is a specification.
This invention relates to new and useful
10 improvements in a draft attachment for au-
tomobiles.
The object of the invention is to provide
an attachment of the character described
whereby a motor vehicle which becomes
15 stalled by reason of soft, muddy or slippery
roads may be enabled to move itself by'a
positive pulling force independent of, or in
conjunction with the traction between the
drive wheels and the road surface.
20 Another object of the invention resides
in the provision of a draft attachment which
may be utilized for the purposes above set
forth for pulling the vehicle forward and
backward and Which may be either manu-
s5 ally driven or driven from the vehicle motor.
A further feature of the invention resides
in the provision of a draft attachment which
may be easily applied to and detached from
the front part of a motor vehicle.
so With the above and other objects in view,
the invention has particular relation to cer-
tain novel features of construction, oper-
ation and arrangement of parts an example
of which is given in this specification and
35 illustrated in the accompanying drawings,
wherein:
Figure lis a front view of an automobile,
showing the attachment fixed thereto.
Fig. 2 is a plan view of the front end of
40 said vehicle.
Fig. 3 is a sectional side view of the front
end of the vehicle showing the attachment
in its relation thereto, and
Fig. 4 is a fragmentary sectional view of
45 a clutch employed.
Fig. 5 is a fragmentary plan view show-
ing the connection of the drum shaft with
the shaft driven thereby.
Fig. 6 shows a plan view of the clutch
50 collar employed.
Referring now more -particularly to the
drawings wherein like numerals of reference.
designate similar parts in each of the figures,'
the numerals 1, 1, refer to the front wheels
85 of the vehicle which support the front axle
2. Secured to said front axle are the frontvehicle springs 3, 3, which in turn support
the forward ends of the side members 4, 4,
of the vehicle frame. A pair of clips 5, 5,
are provided which clip around the forward 60
ends of the side members 4 and the cor-
responding springs 3 as shown in Figs. 1
and 2, said clips being provided with bear-
ings 6, 6, wherein the respective ends of the
transverse shaft 7 'rotate. These clips 5 and 65
the shaft 7 are secured against detachment
by means of the tie bars 8, 8, whose front
ends are formed into open bearings 9, 9,
which receive said rod 7 and whose opposite
ends are turned downwardly forming the 70
shoulders 10 which engage over the front
axle 2 as shown in Fig. 3.
A drum 11 is loosely mounted on the
shaft 7 but may be secured to the shaft so
as to rotate therewith by meansof .the pin 75
12 which passes through alined orifices in
the hub of the drum and said shaft. A
metallic bar 14 is provided whose ends are
formed to rest upon the respective side
members 4, 4. This bar has a central bear- 00
ing to receive the shaft 15 which may be in-
serted therethrough and whose inner end is
formed to connect with the front end of the
engine shaft 16. Loosely mounted upon the
shaft 15 is the sprocket wheel 17 which fits 85
closely against the front side of the bar 14
and which may be clutched with said shaft
or declutched therefrom by means of the
clutch member 18. This member is splined
on the shaft 15 and is conical in form to en- 90
gage in a correspondingly shaped socket in
the hub of the sprocket wheel 17. The shaft
15 has an annular bearing 15' integral there-
with and spaced from the member 18 and in-
terposed between said member and bearing 95
and surrounding said shaft is a clutch col-
lar 18'. A manual lever 19 is provided, the
lower end of which is formed into a collar
19' which fits loosely around said clutch
collar and is provided with a finger 20' 100
which projects into a spiral shaped groove
21' carried by the clutch-collar.. A lateral
pull of the lever 19 will operate to engage
the clutch member 18 in the opposing socket
which will force the sprocket wheel to rotate 105
with the shaft 15, the finger 20' operating
against the sloping side of the groove
21' to cause a relative backward movement
of the collar 19. When the lever is re-
leased the clutch collar will ordinarily dis- 110
engage. The friction between the shaft 15
and the clutch collar 18' will cause said1,2589807.
